OMG The Stupid It Burns

Post Syndicated from Robert Graham original https://blog.erratasec.com/2018/04/omg-stupid-it-burns.html

This article, pointed out by @TheGrugq, is stupid enough that it’s worth rebutting.

The article starts with the question “Why did the lessons of Stuxnet, Wannacry, Heartbleed and Shamoon go unheeded?“. It then proceeds to ignore the lessons of those things.
Some of the actual lessons should be things like how Stuxnet crossed air gaps, how Wannacry spread through flat Windows networking, how Heartbleed comes from technical debt, and how Shamoon furthers state aims by causing damage.
But this article doesn’t cover the technical lessons. Instead, it thinks the lesson should be the moral lesson, that we should take these things more seriously. But that’s stupid. It’s the sort of lesson people teach you that know nothing about the topic. When you have nothing of value to contribute to a topic you can always take the moral high road and criticize everyone for being morally weak for not taking it more seriously. Obviously, since doctors haven’t cured cancer yet, it’s because they don’t take the problem seriously.
The article continues to ignore the lesson of these cyber attacks and instead regales us with a list of military lessons from WW I and WW II. This makes the same flaw that many in the military make, trying to understand cyber through analogies with the real world. It’s not that such lessons could have no value, it’s that this article contains a poor list of them. It seems to consist of a random list of events that appeal to the author rather than events that have bearing on cybersecurity.
Then, in case we don’t get the point, the article bullies us with hyperbole, cliches, buzzwords, bombastic language, famous quotes, and citations. It’s hard to see how most of them actually apply to the text. Rather, it seems like they are included simply because he really really likes them.
The article invests much effort in discussing the buzzword “OODA loop”. Most attacks in cyberspace don’t have one. Instead, attackers flail around, trying lots of random things, overcoming defense with brute-force rather than an understanding of what’s going on. That’s obviously the case with Wannacry: it was an accident, with the perpetrator experimenting with what would happen if they added the ETERNALBLUE exploit to their existing ransomware code. The consequence was beyond anybody’s ability to predict.
You might claim that this is just the first stage, that they’ll loop around, observe Wannacry’s effects, orient themselves, decide, then act upon what they learned. Nope. Wannacry burned the exploit. It’s essentially removed any vulnerable systems from the public Internet, thereby making it impossible to use what they learned. It’s still active a year later, with infected systems behind firewalls busily scanning the Internet so that if you put a new system online that’s vulnerable, it’ll be taken offline within a few hours, before any other evildoer can take advantage of it.
See what I’m doing here? Learning the actual lessons of things like Wannacry? The thing the above article fails to do??
The article has a humorous paragraph on “defense in depth”, misunderstanding the term. To be fair, it’s the cybersecurity industry’s fault: they adopted then redefined the term. That’s why there’s two separate articles on Wikipedia: one for the old military term (as used in this article) and one for the new cybersecurity term.
As used in the cybersecurity industry, “defense in depth” means having multiple layers of security. Many organizations put all their defensive efforts on the perimeter, and none inside a network. The idea of “defense in depth” is to put more defenses inside the network. For example, instead of just one firewall at the edge of the network, put firewalls inside the network to segment different subnetworks from each other, so that a ransomware infection in the customer support computers doesn’t spread to sales and marketing computers.
The article talks about exploiting WiFi chips to bypass the defense in depth measures like browser sandboxes. This is conflating different types of attacks. A WiFi attack is usually considered a local attack, from somebody next to you in bar, rather than a remote attack from a server in Russia. Moreover, far from disproving “defense in depth” such WiFi attacks highlight the need for it. Namely, phones need to be designed so that successful exploitation of other microprocessors (namely, the WiFi, Bluetooth, and cellular baseband chips) can’t directly compromise the host system. In other words, once exploited with “Broadpwn”, a hacker would need to extend the exploit chain with another vulnerability in the hosts Broadcom WiFi driver rather than immediately exploiting a DMA attack across PCIe. This suggests that if PCIe is used to interface to peripherals in the phone that an IOMMU be used, for “defense in depth”.
Cybersecurity is a young field. There are lots of useful things that outsider non-techies can teach us. Lessons from military history would be well-received.
But that’s not this story. Instead, this story is by an outsider telling us we don’t know what we are doing, that they do, and then proceeds to prove they don’t know what they are doing. Their argument is based on a moral suasion and bullying us with what appears on the surface to be intellectual rigor, but which is in fact devoid of anything smart.
My fear, here, is that I’m going to be in a meeting where somebody has read this pretentious garbage, explaining to me why “defense in depth” is wrong and how we need to OODA faster. I’d rather nip this in the bud, pointing out if you found anything interesting from that article, you are wrong.

Netflix, Amazon and Hollywood Sue “SET TV” Over IPTV Piracy

Post Syndicated from Ernesto original https://torrentfreak.com/netflix-amazon-and-hollywood-sue-set-tv-over-iptv-piracy-180422/

In recent years, piracy streaming tools and services have become a prime target for copyright enforcers.

This is particularly true for the Alliance for Creativity and Entertainment (ACE), an anti-piracy partnership forged between Hollywood studios, Netflix, Amazon, and more than two dozen other companies.

After taking action against Kodi-powered devices Tickbox and Dragonbox, key ACE members have now filed a similar lawsuit against the Florida-based company Set Broadcast, LLC, which sells the popular IPTV service SET TV.

The complaint, filed at a California federal court on Friday, further lists company owner Jason Labbosiere and employee Nelson Johnson among the defendants.

According to the movie companies, the Set TV software is little more than a pirate tool, allowing buyers to stream copyright infringing content.

“Defendants market and sell subscriptions to ‘Setvnow,’ a software application that Defendants urge their customers to use as a tool for the mass infringement of Plaintiffs’ copyrighted motion pictures and television shows,” the complaint reads.

In addition to the software, the company also offers a preloaded box. Both allow users to connect to live streams of TV channels and ‘on demand’ content. The latter includes movies that are still in theaters, which SET TV allegedly streams through third-party sources.

“For its on-demand options, Setvnow relies on third-party sources that illicitly reproduce copyrighted works and then provide streams of popular content such as movies still exclusively in theaters and television shows.”

From the complaint

The intended use of SET TV is clear, according to the movie companies. They frame it as a pirate service and believe that this is the main draw for consumers.

“Defendants promote the use of Setvnow for overwhelmingly, if not exclusively, infringing purposes, and that is how their customers use Setvnow,” the complaint reads.

Interestingly, the complaint also states that SET TV pays for sponsored reviews to reach a broader audience. The videos, posted by popular YouTubers such as Solo Man, who is quoted in the complaint, advertise the IPTV service.

“[The] sponsored reviewer promotes Setvnow as a quick and easy way to access on demand movies: ‘You have new releases right there and you simply click on the movie … you click it and click on play again and here you have the movie just like that in 1 2 3 in beautiful HD quality’.”

The lawsuit aims to bring an end to this. The movie companies ask the California District for an injunction to shut down the infringing service and impound all pre-loaded devices. In addition, they’re requesting statutory damages which could go up to several million dollars.

At the time of writing the SET TV website is still in the air, selling subscriptions. The company itself has yet to comment on the allegations.

[$] Rhashtables: under the hood

Post Syndicated from corbet original https://lwn.net/Articles/751974/rss

The first article in this series described
the interface to the “rhashtable”
resizable hash-table abstraction in Linux 4.15. While a knowledge of
the interface can result in successful use of rhashtables, it often
helps to understand what is going on “under the hood”, particularly when
those details leak out through the interface, as is occasionally the
case with rhashtable. The centerpiece for understanding the
implementation is knowing exactly how the table is resized. So this
follow-on article will explain that operation; it will also present the
configuration parameters that were skimmed over last time and discuss
how they affect the implementation.

Russia Blacklists 250 Pirate Sites For Displaying Gambling Ads

Post Syndicated from Andy original https://torrentfreak.com/russia-blacklists-250-pirate-sites-for-displaying-gambling-ads-180421/

Blocking alleged pirate sites is usually a question of proving that they’re involved in infringement and then applying to the courts for an injunction.

In Europe, the process is becoming easier, largely thanks to an EU ruling that permits blocking on copyright grounds.

As reported over the past several years, Russia is taking its blocking processes very seriously. Copyright holders can now have sites blocked in just a few days, if they can show their operators as being unresponsive to takedown demands.

This week, however, Russian authorities have again shown that copyright infringement doesn’t have to be the only Achilles’ heel of pirate sites.

Back in 2006, online gambling was completely banned in Russia. Three years later in 2009, land-based gambling was also made illegal in all but four specified regions. Then, in 2012, the Russian Supreme Court ruled that ISPs must block access to gambling sites, something they had previously refused to do.

That same year, telecoms watchdog Rozcomnadzor began publishing a list of banned domains and within those appeared some of the biggest names in gambling. Many shut down access to customers located in Russia but others did not. In response, Rozcomnadzor also began targeting sites that simply offered information on gambling.

Fast forward more than six years and Russia is still taking a hard line against gambling operators. However, it now finds itself in a position where the existence of gambling material can also assist the state in its quest to take down pirate sites.

Following a complaint from the Federal Tax Service of Russia, Rozcomnadzor has again added a large number of ‘pirate’ sites to the country’s official blocklist after they advertised gambling-related products and services.

“Rozkomnadzor, at the request of the Federal Tax Service of Russia, added more than 250 pirate online cinemas and torrent trackers to the unified register of banned information, which hosted illegal advertising of online casinos and bookmakers,” the telecoms watchdog reported.

Almost immediately, 200 of the sites were blocked by local ISPs since they failed to remove the advertising when told to do so. For the remaining 50 sites, breathing space is still available. Their bans can be suspended if the offending ads are removed within a timeframe specified by the authorities, which has not yet run out.

“Information on a significant number of pirate resources with illegal advertising was received by Rozcomnadzor from citizens and organizations through a hotline that operates on the site of the Unified Register of Prohibited Information, all of which were sent to the Federal Tax Service for making decisions on restricting access,” the watchdog revealed.

Links between pirate sites and gambling companies have traditionally been close over the years, with advertising for many top-tier brands appearing on portals large and small. However, in recent times the prevalence of gambling ads has diminished, in part due to campaigns conducted in the United States, Europe, and the UK.

For pirate site operators in Russia, the decision to carry gambling ads now comes with the added risk of being blocked. Only time will tell whether any reduction in traffic is considered serious enough to warrant a gambling boycott of their own.

Implement continuous integration and delivery of serverless AWS Glue ETL applications using AWS Developer Tools

Post Syndicated from Prasad Alle original https://aws.amazon.com/blogs/big-data/implement-continuous-integration-and-delivery-of-serverless-aws-glue-etl-applications-using-aws-developer-tools/

AWS Glue is an increasingly popular way to develop serverless ETL (extract, transform, and load) applications for big data and data lake workloads. Organizations that transform their ETL applications to cloud-based, serverless ETL architectures need a seamless, end-to-end continuous integration and continuous delivery (CI/CD) pipeline: from source code, to build, to deployment, to product delivery. Having a good CI/CD pipeline can help your organization discover bugs before they reach production and deliver updates more frequently. It can also help developers write quality code and automate the ETL job release management process, mitigate risk, and more.

AWS Glue is a fully managed data catalog and ETL service. It simplifies and automates the difficult and time-consuming tasks of data discovery, conversion, and job scheduling. AWS Glue crawls your data sources and constructs a data catalog using pre-built classifiers for popular data formats and data types, including CSV, Apache Parquet, JSON, and more.

When you are developing ETL applications using AWS Glue, you might come across some of the following CI/CD challenges:

  • Iterative development with unit tests
  • Continuous integration and build
  • Pushing the ETL pipeline to a test environment
  • Pushing the ETL pipeline to a production environment
  • Testing ETL applications using real data (live test)
  • Exploring and validating data

In this post, I walk you through a solution that implements a CI/CD pipeline for serverless AWS Glue ETL applications supported by AWS Developer Tools (including AWS CodePipeline, AWS CodeCommit, and AWS CodeBuild) and AWS CloudFormation.

Solution overview

The following diagram shows the pipeline workflow:

This solution uses AWS CodePipeline, which lets you orchestrate and automate the test and deploy stages for ETL application source code. The solution consists of a pipeline that contains the following stages:

1.) Source Control: In this stage, the AWS Glue ETL job source code and the AWS CloudFormation template file for deploying the ETL jobs are both committed to version control. I chose to use AWS CodeCommit for version control.

To get the ETL job source code and AWS CloudFormation template, download the gluedemoetl.zip file. This solution is developed based on a previous post, Build a Data Lake Foundation with AWS Glue and Amazon S3.

2.) LiveTest: In this stage, all resources—including AWS Glue crawlers, jobs, S3 buckets, roles, and other resources that are required for the solution—are provisioned, deployed, live tested, and cleaned up.

The LiveTest stage includes the following actions:

  • Deploy: In this action, all the resources that are required for this solution (crawlers, jobs, buckets, roles, and so on) are provisioned and deployed using an AWS CloudFormation template.
  • AutomatedLiveTest: In this action, all the AWS Glue crawlers and jobs are executed and data exploration and validation tests are performed. These validation tests include, but are not limited to, record counts in both raw tables and transformed tables in the data lake and any other business validations. I used AWS CodeBuild for this action.
  • LiveTestApproval: This action is included for the cases in which a pipeline administrator approval is required to deploy/promote the ETL applications to the next stage. The pipeline pauses in this action until an administrator manually approves the release.
  • LiveTestCleanup: In this action, all the LiveTest stage resources, including test crawlers, jobs, roles, and so on, are deleted using the AWS CloudFormation template. This action helps minimize cost by ensuring that the test resources exist only for the duration of the AutomatedLiveTest and LiveTestApproval

3.) DeployToProduction: In this stage, all the resources are deployed using the AWS CloudFormation template to the production environment.

Try it out

This code pipeline takes approximately 20 minutes to complete the LiveTest test stage (up to the LiveTest approval stage, in which manual approval is required).

To get started with this solution, choose Launch Stack:

This creates the CI/CD pipeline with all of its stages, as described earlier. It performs an initial commit of the sample AWS Glue ETL job source code to trigger the first release change.

In the AWS CloudFormation console, choose Create. After the template finishes creating resources, you see the pipeline name on the stack Outputs tab.

After that, open the CodePipeline console and select the newly created pipeline. Initially, your pipeline’s CodeCommit stage shows that the source action failed.

Allow a few minutes for your new pipeline to detect the initial commit applied by the CloudFormation stack creation. As soon as the commit is detected, your pipeline starts. You will see the successful stage completion status as soon as the CodeCommit source stage runs.

In the CodeCommit console, choose Code in the navigation pane to view the solution files.

Next, you can watch how the pipeline goes through the LiveTest stage of the deploy and AutomatedLiveTest actions, until it finally reaches the LiveTestApproval action.

At this point, if you check the AWS CloudFormation console, you can see that a new template has been deployed as part of the LiveTest deploy action.

At this point, make sure that the AWS Glue crawlers and the AWS Glue job ran successfully. Also check whether the corresponding databases and external tables have been created in the AWS Glue Data Catalog. Then verify that the data is validated using Amazon Athena, as shown following.

Open the AWS Glue console, and choose Databases in the navigation pane. You will see the following databases in the Data Catalog:

Open the Amazon Athena console, and run the following queries. Verify that the record counts are matching.

SELECT count(*) FROM "nycitytaxi_gluedemocicdtest"."data";
SELECT count(*) FROM "nytaxiparquet_gluedemocicdtest"."datalake";

The following shows the raw data:

The following shows the transformed data:

The pipeline pauses the action until the release is approved. After validating the data, manually approve the revision on the LiveTestApproval action on the CodePipeline console.

Add comments as needed, and choose Approve.

The LiveTestApproval stage now appears as Approved on the console.

After the revision is approved, the pipeline proceeds to use the AWS CloudFormation template to destroy the resources that were deployed in the LiveTest deploy action. This helps reduce cost and ensures a clean test environment on every deployment.

Production deployment is the final stage. In this stage, all the resources—AWS Glue crawlers, AWS Glue jobs, Amazon S3 buckets, roles, and so on—are provisioned and deployed to the production environment using the AWS CloudFormation template.

After successfully running the whole pipeline, feel free to experiment with it by changing the source code stored on AWS CodeCommit. For example, if you modify the AWS Glue ETL job to generate an error, it should make the AutomatedLiveTest action fail. Or if you change the AWS CloudFormation template to make its creation fail, it should affect the LiveTest deploy action. The objective of the pipeline is to guarantee that all changes that are deployed to production are guaranteed to work as expected.

Conclusion

In this post, you learned how easy it is to implement CI/CD for serverless AWS Glue ETL solutions with AWS developer tools like AWS CodePipeline and AWS CodeBuild at scale. Implementing such solutions can help you accelerate ETL development and testing at your organization.

RDS for Oracle: Extending Outbound Network Access to use SSL/TLS

Post Syndicated from Surya Nallu original https://aws.amazon.com/blogs/architecture/rds-for-oracle-extending-outbound-network-access-to-use-ssltls/

In December 2016, we launched the Outbound Network Access functionality for Amazon RDS for Oracle, enabling customers to use their RDS for Oracle database instances to communicate with external web endpoints using the utl_http and utl tcp packages, and sending emails through utl_smtp. We extended the functionality by adding the option of using custom DNS servers, allowing such outbound network accesses to make use of any DNS server a customer chooses to use. These releases enabled HTTP, TCP and SMTP communication originating out of RDS for Oracle instances – limited to non-secure (non-SSL) mediums.

To overcome the limitation over SSL connections, we recently published a whitepaper, that guides through the process of creating customized Oracle wallet bundles on your RDS for Oracle instances. By making use of such wallets, you can now extend the Outbound Network Access capability to have external communications happen over secure (SSL/TLS) connections. This opens up new use cases for your RDS for Oracle instances.

With the right set of certificates imported into your RDS for Oracle instances (through Oracle wallets), your database instances can now:

  • Communicate with a HTTPS endpoint: Using utl_http, access a resource such as https://status.aws.amazon.com/robots.txt
  • Download files from Amazon S3 securely: Using a presigned URL from Amazon S3, you can now download any file over SSL
  • Extending Oracle Database links to use SSL: Database links between RDS for Oracle instances can now use SSL as long as the instances have the SSL option installed
  • Sending email over SMTPS:
    • You can now integrate with Amazon SES to send emails from your database instances and any other generic SMTPS with which the provider can be integrated

These are just a few high-level examples of new use cases that have opened up with the whitepaper. As a reminder, always ensure to have best security practices in place when making use of Outbound Network Access (detailed in the whitepaper).

[$] Finding Spectre vulnerabilities with smatch

Post Syndicated from corbet original https://lwn.net/Articles/752408/rss

The furor over the Meltdown and Spectre vulnerabilities has calmed a bit —
for now, at least — but that does not mean that developers have stopped
worrying about them. Spectre variant 1 (the bounds-check bypass
vulnerability) has been of particular concern because, while the kernel is
thought to contain numerous vulnerable spots, nobody really knows how to
find them all. As a result, the defenses that have been developed for
variant 1 have only been deployed in a few places. Recently, though,
Dan Carpenter has enhanced the smatch tool to enable it to find possibly
vulnerable code in the kernel.

Cloudflare Kicks Out Torrent Site For Abuse Reporting Interference

Post Syndicated from Ernesto original https://torrentfreak.com/cloudflare-kicks-out-torrent-site-for-abuse-reporting-interference-180420/

As one of the leading CDN and DDoS protection services, Cloudflare is used by millions of websites across the globe.

The company’s clients include billion dollar companies and national governments, but also personal blogs, and even pirate sites.

Copyright holders are not happy with the latter category and are pressuring Cloudflare to cut their ties with sites like The Pirate Bay, both in and out of court.

Cloudflare, however, maintains that it’s a neutral service provider. They forward copyright infringement notices to their customers, for example, but deny any liability for these sites.

Generally speaking, the company only disconnects a customer in response to a court order, as it did with Sci-Hub earlier this year. That’s why it came as a surprise when the anime torrent site NYAA.si was disconnected this week.

The site, which is a replacement for the original NYAA, has millions of users and is particularly popular in Japan. Without prior warning, it became unavailable for several hours this week, after Cloudflare removed it from its services. So what happened?

TorrentFreak spoke to the operator who said that the exact reason for the termination remains a mystery to him. He reached out to Cloudflare looking for answers, but the comany simply stated that it’s about “avoiding measures taken to avoid abuse complaints,” as can be seen below.

One of Cloudflare’s messages

The operator says he hasn’t done anything out of the ordinary and showed his willingness to resolve any possible issues. However, that hasn’t changed Cloudflare’s stance.

“We asked multiple times for clarification. We also expressed that we were willing to attempt to work with them on whatever the problem actually was, if they would explain what they even mean.

“Naturally, I have been stonewalled by them at every stage. I’ve contacted numerous persons at Cloudflare and nobody will talk about this,” NYAA’s operator adds.

TorrentFreak asked Cloudflare for more details and the company confirmed that the matter was related to interference with its abuse reporting systems, without providing further detail.

“We determined that the customer had taken steps specifically intended to interfere with and thwart the operation of our abuse reporting systems,” Cloudflare’s General Counsel Doug Kramer informed us.

Cloudflare’s statement suggests that the site took active steps to interfere with the abuse process. The company added that it can’t go into detail, but says that the reason for the termination was shared with the website owner.

The website owner, on the other hand, informs us that he has no clue what the exact problem is. NYAA.si occasionally swaps IP addresses and have recently set up some mirror domains, but these were all under the same account. So, he has no idea why that would interfere with any abuse reports.

“I’m honestly unsure of what we could have done that ‘circumvents” their abuse system,” NYAA’s operator says, adding that the only abuse reports received were copyright related.

It’s unlikely, however, that copyright takedown notices alone would warrant account termination, as most of the largest torrent sites use Cloudflare.

NYAA’s operator says he can do little more than speculate at the point. Some have hinted at a secret court order while Japan’s recent crackdown on manga and anime piracy also came to mind, all without a grain of evidence of course.

Whatever the reason, NYAA.si now has to move on without Cloudflare, while the mystery remains.

“Frankly, this whole thing is a joke. I don’t understand why they would willingly host much bigger sites like ThePirateBay without any issue, or even ISIS, or the various hacking groups that have used them over time,” the operator says.

If more information about the abuse process interfere becomes available, we’ll definitely follow it up.

Securing Elections

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/04/securing_electi_1.html

Elections serve two purposes. The first, and obvious, purpose is to accurately choose the winner. But the second is equally important: to convince the loser. To the extent that an election system is not transparently and auditably accurate, it fails in that second purpose. Our election systems are failing, and we need to fix them.

Today, we conduct our elections on computers. Our registration lists are in computer databases. We vote on computerized voting machines. And our tabulation and reporting is done on computers. We do this for a lot of good reasons, but a side effect is that elections now have all the insecurities inherent in computers. The only way to reliably protect elections from both malice and accident is to use something that is not hackable or unreliable at scale; the best way to do that is to back up as much of the system as possible with paper.

Recently, there have been two graphic demonstrations of how bad our computerized voting system is. In 2007, the states of California and Ohio conducted audits of their electronic voting machines. Expert review teams found exploitable vulnerabilities in almost every component they examined. The researchers were able to undetectably alter vote tallies, erase audit logs, and load malware on to the systems. Some of their attacks could be implemented by a single individual with no greater access than a normal poll worker; others could be done remotely.

Last year, the Defcon hackers’ conference sponsored a Voting Village. Organizers collected 25 pieces of voting equipment, including voting machines and electronic poll books. By the end of the weekend, conference attendees had found ways to compromise every piece of test equipment: to load malicious software, compromise vote tallies and audit logs, or cause equipment to fail.

It’s important to understand that these were not well-funded nation-state attackers. These were not even academics who had been studying the problem for weeks. These were bored hackers, with no experience with voting machines, playing around between parties one weekend.

It shouldn’t be any surprise that voting equipment, including voting machines, voter registration databases, and vote tabulation systems, are that hackable. They’re computers — often ancient computers running operating systems no longer supported by the manufacturers — and they don’t have any magical security technology that the rest of the industry isn’t privy to. If anything, they’re less secure than the computers we generally use, because their manufacturers hide any flaws behind the proprietary nature of their equipment.

We’re not just worried about altering the vote. Sometimes causing widespread failures, or even just sowing mistrust in the system, is enough. And an election whose results are not trusted or believed is a failed election.

Voting systems have another requirement that makes security even harder to achieve: the requirement for a secret ballot. Because we have to securely separate the election-roll system that determines who can vote from the system that collects and tabulates the votes, we can’t use the security systems available to banking and other high-value applications.

We can securely bank online, but can’t securely vote online. If we could do away with anonymity — if everyone could check that their vote was counted correctly — then it would be easy to secure the vote. But that would lead to other problems. Before the US had the secret ballot, voter coercion and vote-buying were widespread.

We can’t, so we need to accept that our voting systems are insecure. We need an election system that is resilient to the threats. And for many parts of the system, that means paper.

Let’s start with the voter rolls. We know they’ve already been targeted. In 2016, someone changed the party affiliation of hundreds of voters before the Republican primary. That’s just one possibility. A well-executed attack that deletes, for example, one in five voters at random — or changes their addresses — would cause chaos on election day.

Yes, we need to shore up the security of these systems. We need better computer, network, and database security for the various state voter organizations. We also need to better secure the voter registration websites, with better design and better internet security. We need better security for the companies that build and sell all this equipment.

Multiple, unchangeable backups are essential. A record of every addition, deletion, and change needs to be stored on a separate system, on write-only media like a DVD. Copies of that DVD, or — even better — a paper printout of the voter rolls, should be available at every polling place on election day. We need to be ready for anything.

Next, the voting machines themselves. Security researchers agree that the gold standard is a voter-verified paper ballot. The easiest (and cheapest) way to achieve this is through optical-scan voting. Voters mark paper ballots by hand; they are fed into a machine and counted automatically. That paper ballot is saved, and serves as a final true record in a recount in case of problems. Touch-screen machines that print a paper ballot to drop in a ballot box can also work for voters with disabilities, as long as the ballot can be easily read and verified by the voter.

Finally, the tabulation and reporting systems. Here again we need more security in the process, but we must always use those paper ballots as checks on the computers. A manual, post-election, risk-limiting audit varies the number of ballots examined according to the margin of victory. Conducting this audit after every election, before the results are certified, gives us confidence that the election outcome is correct, even if the voting machines and tabulation computers have been tampered with. Additionally, we need better coordination and communications when incidents occur.

It’s vital to agree on these procedures and policies before an election. Before the fact, when anyone can win and no one knows whose votes might be changed, it’s easy to agree on strong security. But after the vote, someone is the presumptive winner — and then everything changes. Half of the country wants the result to stand, and half wants it reversed. At that point, it’s too late to agree on anything.

The politicians running in the election shouldn’t have to argue their challenges in court. Getting elections right is in the interest of all citizens. Many countries have independent election commissions that are charged with conducting elections and ensuring their security. We don’t do that in the US.

Instead, we have representatives from each of our two parties in the room, keeping an eye on each other. That provided acceptable security against 20th-century threats, but is totally inadequate to secure our elections in the 21st century. And the belief that the diversity of voting systems in the US provides a measure of security is a dangerous myth, because few districts can be decisive and there are so few voting-machine vendors.

We can do better. In 2017, the Department of Homeland Security declared elections to be critical infrastructure, allowing the department to focus on securing them. On 23 March, Congress allocated $380m to states to upgrade election security.

These are good starts, but don’t go nearly far enough. The constitution delegates elections to the states but allows Congress to “make or alter such Regulations”. In 1845, Congress set a nationwide election day. Today, we need it to set uniform and strict election standards.

timeShift(GrafanaBuzz, 1w) Issue 41

Implementing safe AWS Lambda deployments with AWS CodeDeploy

Post Syndicated from Chris Munns original https://aws.amazon.com/blogs/compute/implementing-safe-aws-lambda-deployments-with-aws-codedeploy/

AWS Lambda and AWS CodeDeploy recently made it possible to automatically shift incoming traffic between two function versions based on a preconfigured rollout strategy. This new feature allows you to gradually shift traffic to the new function. If there are any issues with the new code, you can quickly rollback and control the impact to your application.

Previously, you had to manually move 100% of traffic from the old version to the new version. Now, you can have CodeDeploy automatically execute pre- or post-deployment tests and automate a gradual rollout strategy. Traffic shifting is built right into the AWS Serverless Application Model (SAM), making it easy to define and deploy your traffic shifting capabilities. SAM is an extension of AWS CloudFormation that provides a simplified way of defining serverless applications.

In this post, I show you how to use SAM, CloudFormation, and CodeDeploy to accomplish an automated rollout strategy for safe Lambda deployments.

Scenario

For this walkthrough, you write a Lambda application that returns a count of the S3 buckets that you own. You deploy it and use it in production. Later on, you receive requirements that tell you that you need to change your Lambda application to count only buckets that begin with the letter “a”.

Before you make the change, you need to be sure that your new Lambda application works as expected. If it does have issues, you want to minimize the number of impacted users and roll back easily. To accomplish this, you create a deployment process that publishes the new Lambda function, but does not send any traffic to it. You use CodeDeploy to execute a PreTraffic test to ensure that your new function works as expected. After the test succeeds, CodeDeploy automatically shifts traffic gradually to the new version of the Lambda function.

Your Lambda function is exposed as a REST service via an Amazon API Gateway deployment. This makes it easy to test and integrate.

Prerequisites

To execute the SAM and CloudFormation deployment, you must have the following IAM permissions:

  • cloudformation:*
  • lambda:*
  • codedeploy:*
  • iam:create*

You may use the AWS SAM Local CLI or the AWS CLI to package and deploy your Lambda application. If you choose to use SAM Local, be sure to install it onto your system. For more information, see AWS SAM Local Installation.

All of the code used in this post can be found in this GitHub repository: https://github.com/aws-samples/aws-safe-lambda-deployments.

Walkthrough

For this post, use SAM to define your resources because it comes with built-in CodeDeploy support for safe Lambda deployments.  The deployment is handled and automated by CloudFormation.

SAM allows you to define your Serverless applications in a simple and concise fashion, because it automatically creates all necessary resources behind the scenes. For example, if you do not define an execution role for a Lambda function, SAM automatically creates one. SAM also creates the CodeDeploy application necessary to drive the traffic shifting, as well as the IAM service role that CodeDeploy uses to execute all actions.

Create a SAM template

To get started, write your SAM template and call it template.yaml.

AWSTemplateFormatVersion : '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: An example SAM template for Lambda Safe Deployments.

Resources:

  returnS3Buckets:
    Type: AWS::Serverless::Function
    Properties:
      Handler: returnS3Buckets.handler
      Runtime: nodejs6.10
      AutoPublishAlias: live
      Policies:
        - Version: "2012-10-17"
          Statement: 
          - Effect: "Allow"
            Action: 
              - "s3:ListAllMyBuckets"
            Resource: '*'
      DeploymentPreference:
          Type: Linear10PercentEvery1Minute
          Hooks:
            PreTraffic: !Ref preTrafficHook
      Events:
        Api:
          Type: Api
          Properties:
            Path: /test
            Method: get

  preTrafficHook:
    Type: AWS::Serverless::Function
    Properties:
      Handler: preTrafficHook.handler
      Policies:
        - Version: "2012-10-17"
          Statement: 
          - Effect: "Allow"
            Action: 
              - "codedeploy:PutLifecycleEventHookExecutionStatus"
            Resource:
              !Sub 'arn:aws:codedeploy:${AWS::Region}:${AWS::AccountId}:deploymentgroup:${ServerlessDeploymentApplication}/*'
        - Version: "2012-10-17"
          Statement: 
          - Effect: "Allow"
            Action: 
              - "lambda:InvokeFunction"
            Resource: !Ref returnS3Buckets.Version
      Runtime: nodejs6.10
      FunctionName: 'CodeDeployHook_preTrafficHook'
      DeploymentPreference:
        Enabled: false
      Timeout: 5
      Environment:
        Variables:
          NewVersion: !Ref returnS3Buckets.Version

This template creates two functions:

  • returnS3Buckets
  • preTrafficHook

The returnS3Buckets function is where your application logic lives. It’s a simple piece of code that uses the AWS SDK for JavaScript in Node.JS to call the Amazon S3 listBuckets API action and return the number of buckets.

'use strict';

var AWS = require('aws-sdk');
var s3 = new AWS.S3();

exports.handler = (event, context, callback) => {
	console.log("I am here! " + context.functionName  +  ":"  +  context.functionVersion);

	s3.listBuckets(function (err, data){
		if(err){
			console.log(err, err.stack);
			callback(null, {
				statusCode: 500,
				body: "Failed!"
			});
		}
		else{
			var allBuckets = data.Buckets;

			console.log("Total buckets: " + allBuckets.length);
			callback(null, {
				statusCode: 200,
				body: allBuckets.length
			});
		}
	});	
}

Review the key parts of the SAM template that defines returnS3Buckets:

  • The AutoPublishAlias attribute instructs SAM to automatically publish a new version of the Lambda function for each new deployment and link it to the live alias.
  • The Policies attribute specifies additional policy statements that SAM adds onto the automatically generated IAM role for this function. The first statement provides the function with permission to call listBuckets.
  • The DeploymentPreference attribute configures the type of rollout pattern to use. In this case, you are shifting traffic in a linear fashion, moving 10% of traffic every minute to the new version. For more information about supported patterns, see Serverless Application Model: Traffic Shifting Configurations.
  • The Hooks attribute specifies that you want to execute the preTrafficHook Lambda function before CodeDeploy automatically begins shifting traffic. This function should perform validation testing on the newly deployed Lambda version. This function invokes the new Lambda function and checks the results. If you’re satisfied with the tests, instruct CodeDeploy to proceed with the rollout via an API call to: codedeploy.putLifecycleEventHookExecutionStatus.
  • The Events attribute defines an API-based event source that can trigger this function. It accepts requests on the /test path using an HTTP GET method.
'use strict';

const AWS = require('aws-sdk');
const codedeploy = new AWS.CodeDeploy({apiVersion: '2014-10-06'});
var lambda = new AWS.Lambda();

exports.handler = (event, context, callback) => {

	console.log("Entering PreTraffic Hook!");
	
	// Read the DeploymentId & LifecycleEventHookExecutionId from the event payload
    var deploymentId = event.DeploymentId;
	var lifecycleEventHookExecutionId = event.LifecycleEventHookExecutionId;

	var functionToTest = process.env.NewVersion;
	console.log("Testing new function version: " + functionToTest);

	// Perform validation of the newly deployed Lambda version
	var lambdaParams = {
		FunctionName: functionToTest,
		InvocationType: "RequestResponse"
	};

	var lambdaResult = "Failed";
	lambda.invoke(lambdaParams, function(err, data) {
		if (err){	// an error occurred
			console.log(err, err.stack);
			lambdaResult = "Failed";
		}
		else{	// successful response
			var result = JSON.parse(data.Payload);
			console.log("Result: " +  JSON.stringify(result));

			// Check the response for valid results
			// The response will be a JSON payload with statusCode and body properties. ie:
			// {
			//		"statusCode": 200,
			//		"body": 51
			// }
			if(result.body == 9){	
				lambdaResult = "Succeeded";
				console.log ("Validation testing succeeded!");
			}
			else{
				lambdaResult = "Failed";
				console.log ("Validation testing failed!");
			}

			// Complete the PreTraffic Hook by sending CodeDeploy the validation status
			var params = {
				deploymentId: deploymentId,
				lifecycleEventHookExecutionId: lifecycleEventHookExecutionId,
				status: lambdaResult // status can be 'Succeeded' or 'Failed'
			};
			
			// Pass AWS CodeDeploy the prepared validation test results.
			codedeploy.putLifecycleEventHookExecutionStatus(params, function(err, data) {
				if (err) {
					// Validation failed.
					console.log('CodeDeploy Status update failed');
					console.log(err, err.stack);
					callback("CodeDeploy Status update failed");
				} else {
					// Validation succeeded.
					console.log('Codedeploy status updated successfully');
					callback(null, 'Codedeploy status updated successfully');
				}
			});
		}  
	});
}

The hook is hardcoded to check that the number of S3 buckets returned is 9.

Review the key parts of the SAM template that defines preTrafficHook:

  • The Policies attribute specifies additional policy statements that SAM adds onto the automatically generated IAM role for this function. The first statement provides permissions to call the CodeDeploy PutLifecycleEventHookExecutionStatus API action. The second statement provides permissions to invoke the specific version of the returnS3Buckets function to test
  • This function has traffic shifting features disabled by setting the DeploymentPreference option to false.
  • The FunctionName attribute explicitly tells CloudFormation what to name the function. Otherwise, CloudFormation creates the function with the default naming convention: [stackName]-[FunctionName]-[uniqueID].  Name the function with the “CodeDeployHook_” prefix because the CodeDeployServiceRole role only allows InvokeFunction on functions named with that prefix.
  • Set the Timeout attribute to allow enough time to complete your validation tests.
  • Use an environment variable to inject the ARN of the newest deployed version of the returnS3Buckets function. The ARN allows the function to know the specific version to invoke and perform validation testing on.

Deploy the function

Your SAM template is all set and the code is written—you’re ready to deploy the function for the first time. Here’s how to do it via the SAM CLI. Replace “sam” with “cloudformation” to use CloudFormation instead.

First, package the function. This command returns a CloudFormation importable file, packaged.yaml.

sam package –template-file template.yaml –s3-bucket mybucket –output-template-file packaged.yaml

Now deploy everything:

sam deploy –template-file packaged.yaml –stack-name mySafeDeployStack –capabilities CAPABILITY_IAM

At this point, both Lambda functions have been deployed within the CloudFormation stack mySafeDeployStack. The returnS3Buckets has been deployed as Version 1:

SAM automatically created a few things, including the CodeDeploy application, with the deployment pattern that you specified (Linear10PercentEvery1Minute). There is currently one deployment group, with no action, because no deployments have occurred. SAM also created the IAM service role that this CodeDeploy application uses:

There is a single managed policy attached to this role, which allows CodeDeploy to invoke any Lambda function that begins with “CodeDeployHook_”.

An API has been set up called safeDeployStack. It targets your Lambda function with the /test resource using the GET method. When you test the endpoint, API Gateway executes the returnS3Buckets function and it returns the number of S3 buckets that you own. In this case, it’s 51.

Publish a new Lambda function version

Now implement the requirements change, which is to make returnS3Buckets count only buckets that begin with the letter “a”. The code now looks like the following (see returnS3BucketsNew.js in GitHub):

'use strict';

var AWS = require('aws-sdk');
var s3 = new AWS.S3();

exports.handler = (event, context, callback) => {
	console.log("I am here! " + context.functionName  +  ":"  +  context.functionVersion);

	s3.listBuckets(function (err, data){
		if(err){
			console.log(err, err.stack);
			callback(null, {
				statusCode: 500,
				body: "Failed!"
			});
		}
		else{
			var allBuckets = data.Buckets;

			console.log("Total buckets: " + allBuckets.length);
			//callback(null, allBuckets.length);

			//  New Code begins here
			var counter=0;
			for(var i  in allBuckets){
				if(allBuckets[i].Name[0] === "a")
					counter++;
			}
			console.log("Total buckets starting with a: " + counter);

			callback(null, {
				statusCode: 200,
				body: counter
			});
			
		}
	});	
}

Repackage and redeploy with the same two commands as earlier:

sam package –template-file template.yaml –s3-bucket mybucket –output-template-file packaged.yaml
	
sam deploy –template-file packaged.yaml –stack-name mySafeDeployStack –capabilities CAPABILITY_IAM

CloudFormation understands that this is a stack update instead of an entirely new stack. You can see that reflected in the CloudFormation console:

During the update, CloudFormation deploys the new Lambda function as version 2 and adds it to the “live” alias. There is no traffic routing there yet. CodeDeploy now takes over to begin the safe deployment process.

The first thing CodeDeploy does is invoke the preTrafficHook function. Verify that this happened by reviewing the Lambda logs and metrics:

The function should progress successfully, invoke Version 2 of returnS3Buckets, and finally invoke the CodeDeploy API with a success code. After this occurs, CodeDeploy begins the predefined rollout strategy. Open the CodeDeploy console to review the deployment progress (Linear10PercentEvery1Minute):

Verify the traffic shift

During the deployment, verify that the traffic shift has started to occur by running the test periodically. As the deployment shifts towards the new version, a larger percentage of the responses return 9 instead of 51. These numbers match the S3 buckets.

A minute later, you see 10% more traffic shifting to the new version. The whole process takes 10 minutes to complete. After completion, open the Lambda console and verify that the “live” alias now points to version 2:

After 10 minutes, the deployment is complete and CodeDeploy signals success to CloudFormation and completes the stack update.

Check the results

If you invoke the function alias manually, you see the results of the new implementation.

aws lambda invoke –function [lambda arn to live alias] out.txt

You can also execute the prod stage of your API and verify the results by issuing an HTTP GET to the invoke URL:

Summary

This post has shown you how you can safely automate your Lambda deployments using the Lambda traffic shifting feature. You used the Serverless Application Model (SAM) to define your Lambda functions and configured CodeDeploy to manage your deployment patterns. Finally, you used CloudFormation to automate the deployment and updates to your function and PreTraffic hook.

Now that you know all about this new feature, you’re ready to begin automating Lambda deployments with confidence that things will work as designed. I look forward to hearing about what you’ve built with the AWS Serverless Platform.

Confused About the Hybrid Cloud? You’re Not Alone

Post Syndicated from Roderick Bauer original https://www.backblaze.com/blog/confused-about-the-hybrid-cloud-youre-not-alone/

Hybrid Cloud. What is it?

Do you have a clear understanding of the hybrid cloud? If you don’t, it’s not surprising.

Hybrid cloud has been applied to a greater and more varied number of IT solutions than almost any other recent data management term. About the only thing that’s clear about the hybrid cloud is that the term hybrid cloud wasn’t invented by customers, but by vendors who wanted to hawk whatever solution du jour they happened to be pushing.

Let’s be honest. We’re in an industry that loves hype. We can’t resist grafting hyper, multi, ultra, and super and other prefixes onto the beginnings of words to entice customers with something new and shiny. The alphabet soup of cloud-related terms can include various options for where the cloud is located (on-premises, off-premises), whether the resources are private or shared in some degree (private, community, public), what type of services are offered (storage, computing), and what type of orchestrating software is used to manage the workflow and the resources. With so many moving parts, it’s no wonder potential users are confused.

Let’s take a step back, try to clear up the misconceptions, and come up with a basic understanding of what the hybrid cloud is. To be clear, this is our viewpoint. Others are free to do what they like, so bear that in mind.

So, What is the Hybrid Cloud?

The hybrid cloud refers to a cloud environment made up of a mixture of on-premises private cloud resources combined with third-party public cloud resources that use some kind of orchestration between them.

To get beyond the hype, let’s start with Forrester Research‘s idea of the hybrid cloud: “One or more public clouds connected to something in my data center. That thing could be a private cloud; that thing could just be traditional data center infrastructure.”

To put it simply, a hybrid cloud is a mash-up of on-premises and off-premises IT resources.

To expand on that a bit, we can say that the hybrid cloud refers to a cloud environment made up of a mixture of on-premises private cloud[1] resources combined with third-party public cloud resources that use some kind of orchestration[2] between them. The advantage of the hybrid cloud model is that it allows workloads and data to move between private and public clouds in a flexible way as demands, needs, and costs change, giving businesses greater flexibility and more options for data deployment and use.

In other words, if you have some IT resources in-house that you are replicating or augmenting with an external vendor, congrats, you have a hybrid cloud!

Private Cloud vs. Public Cloud

The cloud is really just a collection of purpose built servers. In a private cloud, the servers are dedicated to a single tenant or a group of related tenants. In a public cloud, the servers are shared between multiple unrelated tenants (customers). A public cloud is off-site, while a private cloud can be on-site or off-site — or on-prem or off-prem.

As an example, let’s look at a hybrid cloud meant for data storage, a hybrid data cloud. A company might set up a rule that says all accounting files that have not been touched in the last year are automatically moved off-prem to cloud storage to save cost and reduce the amount of storage needed on-site. The files are still available; they are just no longer stored on your local systems. The rules can be defined to fit an organization’s workflow and data retention policies.

The hybrid cloud concept also contains cloud computing. For example, at the end of the quarter, order processing application instances can be spun up off-premises in a hybrid computing cloud as needed to add to on-premises capacity.

Hybrid Cloud Benefits

If we accept that the hybrid cloud combines the best elements of private and public clouds, then the benefits of hybrid cloud solutions are clear, and we can identify the primary two benefits that result from the blending of private and public clouds.

Diagram of the Components of the Hybrid Cloud

Benefit 1: Flexibility and Scalability

Undoubtedly, the primary advantage of the hybrid cloud is its flexibility. It takes time and money to manage in-house IT infrastructure and adding capacity requires advance planning.

The cloud is ready and able to provide IT resources whenever needed on short notice. The term cloud bursting refers to the on-demand and temporary use of the public cloud when demand exceeds resources available in the private cloud. For example, some businesses experience seasonal spikes that can put an extra burden on private clouds. These spikes can be taken up by a public cloud. Demand also can vary with geographic location, events, or other variables. The public cloud provides the elasticity to deal with these and other anticipated and unanticipated IT loads. The alternative would be fixed cost investments in on-premises IT resources that might not be efficiently utilized.

For a data storage user, the on-premises private cloud storage provides, among other benefits, the highest speed access. For data that is not frequently accessed, or needed with the absolute lowest levels of latency, it makes sense for the organization to move it to a location that is secure, but less expensive. The data is still readily available, and the public cloud provides a better platform for sharing the data with specific clients, users, or with the general public.

Benefit 2: Cost Savings

The public cloud component of the hybrid cloud provides cost-effective IT resources without incurring capital expenses and labor costs. IT professionals can determine the best configuration, service provider, and location for each service, thereby cutting costs by matching the resource with the task best suited to it. Services can be easily scaled, redeployed, or reduced when necessary, saving costs through increased efficiency and avoiding unnecessary expenses.

Comparing Private vs Hybrid Cloud Storage Costs

To get an idea of the difference in storage costs between a purely on-premises solutions and one that uses a hybrid of private and public storage, we’ll present two scenarios. For each scenario we’ll use data storage amounts of 100 terabytes, 1 petabyte, and 2 petabytes. Each table is the same format, all we’ve done is change how the data is distributed: private (on-premises) cloud or public (off-premises) cloud. We are using the costs for our own B2 Cloud Storage in this example. The math can be adapted for any set of numbers you wish to use.

Scenario 1    100% of data on-premises storage

Data Stored
Data stored On-Premises: 100% 100 TB 1,000 TB 2,000 TB
On-premises cost range Monthly Cost
Low — $12/TB/Month $1,200 $12,000 $24,000
High — $20/TB/Month $2,000 $20,000 $40,000

Scenario 2    20% of data on-premises with 80% public cloud storage (B2)

Data Stored
Data stored On-Premises: 20% 20 TB 200 TB 400 TB
Data stored in Cloud: 80% 80 TB 800 TB 1,600 TB
On-premises cost range Monthly Cost
Low — $12/TB/Month $240 $2,400 $4,800
High — $20/TB/Month $400 $4,000 $8,000
Public cloud cost range Monthly Cost
Low — $5/TB/Month (B2) $400 $4,000 $8,000
High — $20/TB/Month $1,600 $16,000 $32,000
On-premises + public cloud cost range Monthly Cost
Low $640 $6,400 $12,800
High $2,000 $20,000 $40,000

As can be seen in the numbers above, using a hybrid cloud solution and storing 80% of the data in the cloud with a provider such as Backblaze B2 can result in significant savings over storing only on-premises. For other cost scenarios, see the B2 Cost Calculator.

When Hybrid Might Not Always Be the Right Fit

There are circumstances where the hybrid cloud might not be the best solution. Smaller organizations operating on a tight IT budget might best be served by a purely public cloud solution. The cost of setting up and running private servers is substantial.

An application that requires the highest possible speed might not be suitable for hybrid, depending on the specific cloud implementation. While latency does play a factor in data storage for some users, it is less of a factor for uploading and downloading data than it is for organizations using the hybrid cloud for computing. Because Backblaze recognized the importance of speed and low-latency for customers wishing to use computing on data stored in B2, we directly connected our data centers with those of our computing partners, ensuring that latency would not be an issue even for a hybrid cloud computing solution.

It is essential to have a good understanding of workloads and their essential characteristics in order to make the hybrid cloud work well for you. Each application needs to be examined for the right mix of private cloud, public cloud, and traditional IT resources that fit the particular workload in order to benefit most from a hybrid cloud architecture.

The Hybrid Cloud Can Be a Win-Win Solution

From the high altitude perspective, any solution that enables an organization to respond in a flexible manner to IT demands is a win. Avoiding big upfront capital expenses for in-house IT infrastructure will appeal to the CFO. Being able to quickly spin up IT resources as they’re needed will appeal to the CTO and VP of Operations.

Should You Go Hybrid?

We’ve arrived at the bottom line and the question is, should you or your organization embrace hybrid cloud infrastructures?

According to 451 Research, by 2019, 69% of companies will operate in hybrid cloud environments, and 60% of workloads will be running in some form of hosted cloud service (up from 45% in 2017). That indicates that the benefits of the hybrid cloud appeal to a broad range of companies.

In Two Years, More Than Half of Workloads Will Run in Cloud

Clearly, depending on an organization’s needs, there are advantages to a hybrid solution. While it might have been possible to dismiss the hybrid cloud in the early days of the cloud as nothing more than a buzzword, that’s no longer true. The hybrid cloud has evolved beyond the marketing hype to offer real solutions for an increasingly complex and challenging IT environment.

If an organization approaches the hybrid cloud with sufficient planning and a structured approach, a hybrid cloud can deliver on-demand flexibility, empower legacy systems and applications with new capabilities, and become a catalyst for digital transformation. The result can be an elastic and responsive infrastructure that has the ability to quickly respond to changing demands of the business.

As data management professionals increasingly recognize the advantages of the hybrid cloud, we can expect more and more of them to embrace it as an essential part of their IT strategy.

Pirates Taunt Amazon Over New “Turd Sandwich” Prime Video Quality

Post Syndicated from Andy original https://torrentfreak.com/pirates-taunt-amazon-over-new-turd-sandwich-prime-video-quality-180419/

Even though they generally aren’t paying for the content they consume, don’t fall into the trap of believing that all pirates are eternally grateful for even poor quality media.

Without a doubt, some of the most quality-sensitive individuals are to be found in pirate communities and they aren’t scared to make their voices known when release groups fail to come up with the best possible goods.

This week there’s been a sustained chorus of disapproval over the quality of pirate video releases sourced from Amazon Prime. The anger is usually directed at piracy groups who fail to capture content in the correct manner but according to a number of observers, the problem is actually at Amazon’s end.

Discussions on Reddit, for example, report that episodes in a single TV series have been declining in filesize and bitrate, from 1.56 GB in 720p at a 3073 kb/s video bitrate for episode 1, down to 907 MB in 720p at just 1514 kb/s video bitrate for episode 10.

Numerous theories as to why this may be the case are being floated around, including that Amazon is trying to save on bandwidth expenses. While this is a possibility, the company hasn’t made any announcements to that end.

Indeed, one legitimate customer reported that he’d raised the quality issue with Amazon and they’d said that the problem was “probably on his end”.

“I have Amazon Prime Video and I noticed the quality was always great for their exclusive shows, so I decided to try buying the shows on Amazon instead of iTunes this year. I paid for season pass subscriptions for Legion, Billions and Homeland this year,” he wrote.

“Just this past weekend, I have noticed a significant drop in details compared to weeks before! So naturally I assumed it was an issue on my end. I started trying different devices, calling support, etc, but nothing really helped.

“Billions continued to look like a blurry mess, almost like I was watching a standard definition DVD instead of the crystal clear HD I paid for and have experienced in the past! And when I check the previous episodes, sure enough, they look fantastic again. What the heck??”

With Amazon distancing itself from the issues, piracy groups have already begun to dig in the knife. Release group DEFLATE has been particularly critical.

“Amazon, in their infinite wisdom, have decided to start fucking with the quality of their encodes. They’re now reaching Netflix’s subpar 1080p.H264 levels, and their H265 encodes aren’t even close to what Netflix produces,” the group said in a file attached to S02E07 of The Good Fight released on Sunday.

“Netflix is able to produce drastic visual improvements with their H265 encodes compared to H264 across every original. In comparison, Amazon can’t decide whether H265 or H264 is going to produce better results, and as a result we suffer for it.”

Arrr! The quality be fallin’

So what’s happening exactly?

A TorrentFreak source (who tells us he’s been working in the BluRay/DCP authoring business for the last 10 years) was kind enough to give us two opinions, one aimed at the techies and another at us mere mortals.

“In technical terms, it appears [Amazon has] increased the CRF [Constant Rate Factor] value they use when encoding for both the HEVC [H265] and H264 streams. Previously, their H264 streams were using CRF 18 and a max bitrate of 15Mbit/s, which usually resulted in file sizes of roughly 3GB, or around 10Mbit/s. Similarly with their HEVC streams, they were using CRF 20 and resulting in streams which were around the same size,” he explained.

“In the past week, the H264 streams have decreased by up to 50% for some streams. While there are no longer any x264 headers embedded in the H264 streams, the HEVC streams still retain those headers and the CRF value used has been increased, so it does appear this change has been done on purpose.”

In layman’s terms, our source believes that Amazon had previously been using an encoding profile that was “right on the edge of relatively good quality” which kept bitrates relatively low but high enough to ensure no perceivable loss of quality.

“H264 streams encoded with CRF 18 could provide an acceptable compromise between quality and file size, where the loss of detail is often negligible when watched at regular viewing distances, at a desk, or in a lounge room on a larger TV,” he explained.

“Recently, it appears these values have been intentionally changed in order to lower the bitrate and file sizes for reasons unknown. As a result, the quality of some streams has been reduced by up to 50% of their previous values. This has introduced a visual loss of quality, comparable to that of viewing something in standard definition versus high definition.”

With the situation failing to improve during the week, by the time piracy group DEFLATE released S03E14 of Supergirl on Tuesday their original criticism had transformed into flat-out insults.

“These are only being done in H265 because Amazon have shit the bed, and it’s a choice between a turd sandwich and a giant douche,” they wrote, offering these images as illustrative of the problem and these indicating what should be achievable.

With DEFLATE advising customers to start complaining to Amazon, the memes have already begun, with unfavorable references to now-defunct group YIFY (which was often chastized for its low quality rips) and even a spin on one of the most well known anti-piracy campaigns.

You wouldn’t download stream….

TorrentFreak contacted Amazon Prime for comment on both the recent changes and growing customer complaints but at the time of publication we were yet to receive a response.

In 2012, Coolest Projects was conceived as an opportunity for CoderDojo Ninjas to showcase their work and for supporters to acknowledge these achievements. Week after week, Ninjas would meet up to work diligently on their projects, hacks, and code; however, it can be difficult for them to see their long-term progress on a project when they’re concentrating on its details on a weekly basis. Coolest Projects became a dedicated time each year for Ninjas and supporters to reflect, celebrate, and share both the achievements and challenges of the maker’s journey.

Audit Trail Overview

Post Syndicated from Bozho original https://techblog.bozho.net/audit-trail-overview/

As part of my current project (secure audit trail) I decided to make a survey about the use of audit trail “in the wild”.

I haven’t written in details about this project of mine (unlike with some other projects). Mostly because it’s commercial and I don’t want to use my blog as a direct promotion channel (though I am doing that at the moment, ironically). But the aim of this post is to shed some light on how audit trail is used.

The survey can be found here. The questions are basically: does your current project have audit trail functionality, and if yes, is it protected from tampering. If not – do you think you should have such functionality.

The results are interesting (although with only around 50 respondents)

So more than half of the systems (on which respondents are working) don’t have audit trail. While audit trail is recommended by information security and related standards, it may not find place in the “busy schedule” of a software project, even though it’s fairly easy to provide a trivial implementation (e.g. I’ve written how to quickly setup one with Hibernate and Spring)

A trivial implementation might do in many cases but if the audit log is critical (e.g. access to sensitive data, performing financial operations etc.), then relying on a trivial implementation might not be enough. In other words – if the sysadmin can access the database and delete or modify the audit trail, then it doesn’t serve much purpose. Hence the next question – how is the audit trail protected from tampering:

And apparently, from the less than 50% of projects with audit trail, around 50% don’t have technical guarantees that the audit trail can’t be tampered with. My guess is it’s more, because people have different understanding of what technical measures are sufficient. E.g. someone may think that digitally signing your log files (or log records) is sufficient, but in fact it isn’t, as whole files (or records) can be deleted (or fully replaced) without a way to detect that. Timestamping can help (and a good audit trail solution should have that), but it doesn’t guarantee the order of events or prevent a malicious actor from deleting or inserting fake ones. And if timestamping is done on a log file level, then any not-yet-timestamped log file is vulnerable to manipulation.

I’ve written about event logs before and their two flavours – event sourcing and audit trail. An event log can effectively be considered audit trail, but you’d need additional security to avoid the problems mentioned above.

So, let’s see what would various levels of security and usefulness of audit logs look like. There are many papers on the topic (e.g. this and this), and they often go into the intricate details of how logging should be implemented. I’ll try to give an overview of the approaches:

  • Regular logs – rely on regular INFO log statements in the production logs to look for hints of what has happened. This may be okay, but is harder to look for evidence (as there is non-auditable data in those log files as well), and it’s not very secure – usually logs are collected (e.g. with graylog) and whoever has access to the log collector’s database (or search engine in the case of Graylog), can manipulate the data and not be caught
  • Designated audit trail – whether it’s stored in the database or in logs files. It has the proper business-event level granularity, but again doesn’t prevent or detect tampering. With lower risk systems that may is perfectly okay.
  • Timestamped logs – whether it’s log files or (harder to implement) database records. Timestamping is good, but if it’s not an external service, a malicious actor can get access to the local timestamping service and issue fake timestamps to either re-timestamp tampered files. Even if the timestamping is not compromised, whole entries can be deleted. The fact that they are missing can sometimes be deduced based on other factors (e.g. hour of rotation), but regularly verifying that is extra effort and may not always be feasible.
  • Hash chaining – each entry (or sequence of log files) could be chained (just as blockchain transactions) – the next one having the hash of the previous one. This is a good solution (whether it’s local, external or 3rd party), but it has the risk of someone modifying or deleting a record, getting your entire chain and re-hashing it. All the checks will pass, but the data will not be correct
  • Hash chaining with anchoring – the head of the chain (the hash of the last entry/block) could be “anchored” to an external service that is outside the capabilities of a malicious actor. Ideally, a public blockchain, alternatively – paper, a public service (twitter), email, etc. That way a malicious actor can’t just rehash the whole chain, because any check against the external service would fail.
  • WORM storage (write once, ready many). You could send your audit logs almost directly to WORM storage, where it’s impossible to replace data. However, that is not ideal, as WORM storage can be slow and expensive. For example AWS Glacier has rather big retrieval times and searching through recent data makes it impractical. It’s actually cheaper than S3, for example, and you can have expiration policies. But having to support your own WORM storage is expensive. It is a good idea to eventually send the logs to WORM storage, but “fresh” audit trail should probably not be “archived” so that it’s searchable and some actionable insight can be gained from it.
  • All-in-one – applying all of the above “just in case” may be unnecessary for every project out there, but that’s what I decided to do at LogSentinel. Business-event granularity with timestamping, hash chaining, anchoring, and eventually putting to WORM storage – I think that provides both security guarantees and flexibility.

I hope the overview is useful and the results from the survey shed some light on how this aspect of information security is underestimated.

IsoHunt Founder Returns With New Search Tool

Post Syndicated from Ernesto original https://torrentfreak.com/isohunt-founder-returns-with-new-search-tool-180419/

Of all the major torrent sites that dominated the Internet at the beginning of this decade, only a few remain.

One of the sites that fell prey to ever-increasing pressure from the entertainment industry was isoHunt.

Founded by the Canadian entrepreneur Gary Fung, the site was one of the early pioneers in the world of torrents, paving the way for many others. However, this spotlight also caught the attention of the major movie studios.

After a lengthy legal battle isoHunt’s founder eventually shut down the site late 2013. This happened after Fung signed a settlement agreement with Hollywood for no less than $110 million, on paper at least.

Launching a new torrent search engine was never really an option, but Fung decided not to let his expertise go to waste. He focused his time and efforts on a new search project instead, which was unveiled to the public this week.

The new app called “WonderSwipe” has just been added to Apple’s iOS store. It’s a mobile search app that ties into Google’s backend, but with a different user interface. While it has nothing to do with file-sharing, we decided to reach out to isoHunt’s founder to find out more.

Fung tells us that he got the idea for the app because he was frustrated with Google’s default search options on the mobile platform.

“I find myself barely do any search on the smartphone, most of the time waiting until I get to my desktop. I ask why?” Fung tells us.

One of the main issues he identified is the fact that swiping is not an option. Instead, people end up browsing through dozens of mobile browser tabs. So, Fung took Google’s infrastructure and search power, making it swipeable.

“From a UI design perspective, I find swiping through photos on the first iPhone one of the most extraordinary advances in computing. It’s so easy that babies would be doing it before they even learn how to flip open a book!

“Bringing that ease of use to the central way of conducting mobile search and research is the initial eureka I had in starting work on WonderSwipe,” Fung adds.

That was roughly three years ago, and a few hours ago WonderSwipe finally made its way into the App store. Android users will have to wait for now, but the application will eventually be available on that platform as well.

In addition to swiping through search results, the app also promises faster article loading and browsing, a reader mode with condensed search results, and a hands-free mode with automated browsing where summaries are read out loud.

WonderwSwipe


Of course, WonderSwipe is nothing like isoHunt ever was, apart from the fact that Google is a search engine that also links to torrents, indirectly.

This similarity was also brought up during the lawsuit with the MPAA, when Fung’s legal team likened isoHunt to Google in court. However, the Canadian entrepreneur doesn’t expect that Hollywood will have an issue with WonderSwipe in particular.

“isoHunt was similar to Google in how it worked as a search engine, but not in scope. Torrents are a small subset of all the webpages Google indexes,” Fung says.

“WonderSwipe’s aim is to find answers in all webpages, powered by Google search results. It presents results in extracted text and summaries with no connection to BitTorrent clients. As such, WonderSwipe can be bigger than isoHunt has ever been.”

Ironically, in recent years Hollywood has often criticized Google for linking to pirated content in its search results. These results will also be available through WonderSwipe.

However, Fung says that any copyright issues with WonderSwipe will have to be dealt with on the search engine level, by Google.

“If there are links to pirated content, tell search engines so they can take them down!” he says.

WonderSwipe is totally free and Fung tells us that he plans to monetize it with in-app purchases for pro features, and non-intrusive advertising that won’t slow down swiping or search results. More details on the future plans for the app are available here.

Pirate Party Urges Swedish Govt to Stop ‘Copyright Troll’ Invasion

Post Syndicated from Ernesto original https://torrentfreak.com/pirate-party-urges-swedish-govt-to-stop-copyright-troll-invasion-180418/

In recent years, millions of file-sharers around the world have been ordered to pay significant settlement fees, or face legal repercussions.

These so-called “copyright trolling” efforts have been a common occurrence in several countries, with Sweden one of the latest hunting grounds.

Over the past months, tens of thousands of Swedes have been targeted in this manner.

The copyright holders go to court, armed with a list of IP-addresses, and when permission is granted they ask the associated ISPs for the account details of individual subscribers.

These suspected pirates then get a settlement demand in their mailbox, urging them to pay the equivalent of a few hundred dollars, or have their day in court.

As in many other countries, these practices are not without controversy. Several experts have spoken out against them, and ISPs have raised objections too. However, according to Swedish law, the rightsholders have the right to pursue these cases.

Despite its name, the Swedish Pirate Party has been relatively silent on the issue. However, that changed this week, as the party now calls on Justice Minister Morgan Johansson to take action.

The Pirate Party describes the copyright trolling efforts as extortion. It stresses that the evidence copyright holders rely on is far from solid, something they believe the courts should take into account.

“It is a scandal that the Swedish judicial system facilitates the mafia-like methods of copyright trolls,” says Pirate Party leader Magnus Andersson.

“To condone the sending of extortion letters without reasonable ground for suspicion of criminal activity is not acceptable. We demand the Justice Minister to do something about the situation with these copyright trolls!”

The Pirate Party sees plenty of opportunities to intervene. The Government could, for example, change how the IPRED directive is interpreted and demand higher scrutiny of the provided evidence.

Another option would be to work at the EU level to repeal the IPRED-directive in its entirety.

Besides calling on the Justice Minister to take action, the Pirate Party is also backing the anti-copyright troll initiative of Internet provider Bahnhof. Through this campaign, members of the public can voice their concerns to the Swedish Government.

Through these and other efforts, the Pirate Party hopes that something will be done to protect the public from the ‘trolling’ practices.

“We cannot accept a situation where private companies use the judicial system as a weapon of fear to extort innocent people,” Andersson tells TorrentFreak.

“This creates contempt for the judiciary and supports the view that the courts only exist to serve the state’s and the big companies’ interests,” he adds.

Thus far the copyright holders have shown no sign of backing down. They refute the “trolling” characterizations and counter that they are merely enforcing their rights. And with the courts on their side, they have little to worry about for now.

Oblivious DNS

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/04/oblivious_dns.html

Interesting idea:

…we present Oblivious DNS (ODNS), which is a new design of the DNS ecosystem that allows current DNS servers to remain unchanged and increases privacy for data in motion and at rest. In the ODNS system, both the client is modified with a local resolver, and there is a new authoritative name server for .odns. To prevent an eavesdropper from learning information, the DNS query must be encrypted; the client generates a request for www.foo.com, generates a session key k, encrypts the requested domain, and appends the TLD domain .odns, resulting in {www.foo.com}k.odns. The client forwards this, with the session key encrypted under the .odns authoritative server’s public key ({k}PK) in the “Additional Information” record of the DNS query to the recursive resolver, which then forwards it to the authoritative name server for .odns. The authoritative server decrypts the session key with his private key, and then subsequently decrypts the requested domain with the session key. The authoritative server then forwards the DNS request to the appropriate name server, acting as a recursive resolver. While the name servers see incoming DNS requests, they do not know which clients they are coming from; additionally, an eavesdropper cannot connect a client with her corresponding DNS queries.
