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.

My letter urging Georgia governor to veto anti-hacking bill

Post Syndicated from Robert Graham original https://blog.erratasec.com/2018/04/my-letter-urging-georgia-governor-to.html

February 16, 2018

Office of the Governor
206 Washington Street
111 State Capitol
Atlanta, Georgia 30334

Re: SB 315

Dear Governor Deal:

I am writing to urge you to veto SB315, the “Unauthorized Computer Access” bill.

The cybersecurity community, of which Georgia is a leader, is nearly unanimous that SB315 will make cybersecurity worse. You’ve undoubtedly heard from many of us opposing this bill. It does not help in prosecuting foreign hackers who target Georgian computers, such as our elections systems. Instead, it prevents those who notice security flaws from pointing them out, thereby getting them fixed. This law violates the well-known Kirchhoff’s Principle, that instead of secrecy and obscurity, that security is achieved through transparency and openness.

That the bill contains this flaw is no accident. The justification for this bill comes from an incident where a security researcher noticed a Georgia state election system had made voter information public. This remained unfixed, months after the vulnerability was first disclosed, leaving the data exposed. Those in charge decided that it was better to prosecute those responsible for discovering the flaw rather than punish those who failed to secure Georgia voter information, hence this law.

Too many security experts oppose this bill for it to go forward. Signing this bill, one that is weak on cybersecurity by favoring political cover-up over the consensus of the cybersecurity community, will be part of your legacy. I urge you instead to veto this bill, commanding the legislature to write a better one, this time consulting experts, which due to Georgia’s thriving cybersecurity community, we do not lack.

Thank you for your attention.

Sincerely,
Robert Graham

EU Content Rules to Improve Access & Reduce Piracy Start April 1

Post Syndicated from Andy original https://torrentfreak.com/eu-content-rules-to-improve-access-reduce-piracy-start-april-1-180328/

Any subscriber of a service like Netflix will tell you that where you live can have a big impact on the content made available. Customers in the US enjoy large libraries while less populous countries are treated less well.

For many years and before Netflix largely closed the loophole, customers would bypass these restrictions, using VPNs to trick Netflix into thinking they were elsewhere. Some wouldn’t bother with the complication, choosing to pirate content instead.

But for citizens of the EU, things were even more complex. While the EU mandates free movement of people, the same can’t be said about licensing deals. While a viewer in the Netherlands could begin watching a movie at home, he could travel to France for a weekend break only to find that the content he paid for is not available, or only in French.

Last May, this problem was addressed by the European Parliament with an agreement to introduce new ‘Cross-border portability’ rules that will give citizens the freedom to enjoy their media wherever they are in the EU, without having to resort to piracy or VPNs – if they can find one that still works for any length of time with the service.

Now, almost 11 months on, the rules are about to come into force. From Sunday, content portability in the EU will become a reality.

“Citizens are at the core of all our digital initiatives. As of 1 April, wherever you are traveling to in the EU, you will no longer miss out on your favorite films, TV series, sports broadcasts, games or e-books, that you have digitally subscribed to at home,” European Commission Vice-President Andrus Ansip said in a statement.

“Removing the boundaries that prevented Europeans from traveling with digital media and content subscriptions is yet another success of the Digital Single Market for our citizens, following the effective abolition of roaming charges that consumers all over Europe have enjoyed since June 2017.”

This is how it will work. Consumers in the EU who buy or subscribe to films, sports broadcasts, music, e-books or games in their home Member States will now be able to access this content when they reside temporarily in another EU country.

So, if a person in the UK purchases Netflix to gain access to a TV show to watch in their home country, Netflix will have to add this content to the customer’s library so they can still access it wherever they travel in the EU, regardless of its general availability elsewhere.

“[P]roviders of paid-for online content services (such as online movie, TV or music streaming services) have to provide their subscribers with the same service wherever the subscriber is in the EU,” the Commission explains.

“The service needs to be provided in the same way in other Member States, as in the Member State of residence. So for Netflix for example, you will have access to the same selection (or catalog) anywhere in the EU, if you are temporarily abroad, just as if you were at home.”

The same should hold true for all other digital content. If it’s available at home, it must be made available elsewhere in Europe in order to comply with the regulations. In doing so, providers are allowed some freedom, provided it’s in the customer’s favor. If they want to give customers additional access to full home and overseas catalogs when they’re traveling, for example, that is fine.

There’s also a plus in there for content providers. While a company like Netflix will sometimes acquire rights on a per country basis, when a citizen travels abroad within the EU they will not be required to obtain licenses for those other territories where their subscribers stay temporarily.

There is, however, a question of what “temporarily” means since it’s not tightly defined in the regulations. The term will cover business trips and holidays, for example, but providers will be required to clearly inform their customers of their precise terms and conditions.

Providers will also need to determine a customer’s home country, something that will be established when a customer signs up or renews his contract. This can be achieved in a number of ways, including via payment details, a contract for an Internet or telephone connection, verifying a home address, or using a simple IP address check.

For providers of free online services, which are allowed to choose whether they want to be included in the new rules or not, there are special conditions in place.

“Once they opt-in and allow portability under the Regulation, all rules will apply to them in the same manner as for the paid services. This means that the subscribers will have to log-in to be able to access and use content when temporarily abroad, and service providers will have to verify the Member State of residence of the subscriber,” the Commission explains.

“If providers of free of charge online content services decide to make use of the new portability rules, they are required to inform their subscribers about this decision prior to providing the service. Such information could, for example, be announced on the providers’ websites.”

The good news for consumers is that providers will not be able to charge for offering content portability and if they don’t provide it as required, they’ll be in breach of EU rules. The EU believes that all providers are ready to meet the standard – the public will find out on Sunday.

Dotcom Affidavit Calls For Obama to Give Evidence in Megaupload Case

Post Syndicated from Andy original https://torrentfreak.com/dotcom-affidavit-calls-for-obama-to-give-evidence-in-megaupload-case-180320/

For more than six years since the raid on Megaupload, founder Kim Dotcom has insisted that the case against him, his co-defendants, and his company, was politically motivated.

The serial entrepreneur states unequivocally that former president Barack Obama’s close ties to Hollywood were the driving force.

Later today, Obama will touch down for a visit to New Zealand. In what appears to be a tightly managed affair, with heavy restrictions placed on the media and publicity, it seems clear that Obama wants to maintain control over his social and business engagements in the country.

But of course, New Zealand is home to Kim Dotcom and as someone who feels wronged by the actions of the former administration, he is determined to use this opportunity to shine more light on Obama’s role in the downfall of his company.

In a statement this morning, Dotcom reiterated his claims that attempts to have him extradited to the United States have no basis in law, chiefly due to the fact that the online dissemination of copyright-protected works by Megaupload’s users is not an extradition offense in New Zealand.

But Dotcom also attacks the politics behind his case, arguing that the Obama administration was under pressure from Hollywood to do something about copyright enforcement or risk losing financial support.

In connection with his case, Dotcom is currently suing the New Zealand government for billions of dollars so while Obama is in town, Dotcom is demanding that the former president gives evidence.

Dotcom’s case is laid out in a highly-detailed sworn affidavit dated March 19, 2018. The Megaupload founder explains that Hollywood has historically been a major benefactor of the Democrats so when seeking re-election for a further term, the Democrats were under pressure from the movie companies to make an example of Megaupload and Dotcom.

Dotcom notes that while he was based in Hong Kong, extradition to the US would be challenging. So, with Dotcom seeking residence in New Zealand, a plot was hatched to allow him into the country, despite the New Zealand government knowing that a criminal prosecution lay in wait for him. Dotcom says that by doing a favor for Hollywood, it could mean that New Zealand became a favored destination for US filmmakers.

“The interests of the United States and New Zealand were therefore perfectly aligned. I provided the perfect opportunity for New Zealand to facilitate the United States’ show of force on copyright enforcement,” Dotcom writes.

Citing documents obtained from Open Secrets, Dotcom shows how the Democrats took an 81% share of more than $46m donated to political parties in the US during the 2008 election cycle. In the 2010 cycle, 76% of more than $24m went to the Democrats and in 2012, they scooped up 78% of more than $56m.

Dotcom then recalls the attempts at passing the Stop Online Piracy Act (SOPA), which would have shifted the enforcement of copyright onto ISPs, assisting Hollywood greatly. Ultimately, Congressional support for the proposed legislation was withdrawn and Dotcom recalls this was followed by a public threat from the MPAA to withdraw campaign contributions on which the Democrats were especially reliant.

“The message to the White House was plain: do not expect funding if you do not advance the MPAA’s legislative agenda. On 20 January 2012, the day after this statement, I was arrested,” Dotcom notes.

Describing Megaupload as a highly profitable and innovative platform that highlighted copyright owners’ failure to keep up with the way in which content is now consumed, Dotcom says it made the perfect target for the Democrats.

Convinced the party was at the root of his prosecution, he utilized his connections in Hong Kong to contact Thomas Hart, a lawyer and lobbyist in Washington, D.C. with strong connections to the Democrats and the White House.

Dotcom said a telephone call between him and Mr Hart revealed that then Vice President Joe Biden was at the center of Dotcom’s prosecution but that Obama was dissatisfied with the way things had been handled.

“Biden did admit to have… you know, kind of started it, you know, along with support from others but it was Biden’s decision…,” Hart allegedly said.

“What he [President Obama] expressed to me was a growing concern about the matter. He indicated an awareness of that it had not gone well, that it was more complicated than he thought, that he will turn his attention to it more prominently after November.”

Dotcom says that Obama was “questioning the whole thing,” a suggestion that he may not have been fully committed to the continuing prosecution.

The affidavit then lists a whole series of meetings in 2011, documented in the White House visitor logs. They include meetings with then United States Attorney Neil McBride, various representatives from Hollywood, MPAA chief Chris Dodd, Mike Ellis of the MPA (who was based in Hong Kong and had met with New Zealand’s then Minister of Justice, Simon Power) and the Obama administration.

In summary, Dotcom suggests there was a highly organized scheme against him, hatched between Hollywood and the Obama administration, that had the provision of funds to win re-election at its heart.

From there, an intertwined agreement was reached at the highest levels of both the US and New Zealand governments where the former would benefit through tax concessions to Hollywood (and a sweetening of relations between the countries) and the latter would benefit financially through investment.

All New Zealand had to do was let Dotcom in for a while and then hand him over to the United States for prosecution. And New Zealand definitely knew that Dotcom was wanted by the US. Emails obtained by Dotcom concerning his residency application show that clearly.

“Kim DOTCOM is not of security concern but is likely to soon become the subject of a joint FBI / NZ Police criminal investigation. We have passed this over to NZ Police,” one of the emails reads. Another, well over a year before the raid, also shows the level of knowledge.

Bad but wealthy, so we have plans for him…

With “political pressure” to grant Dotcom’s application in place, Immigration New Zealand finally gave the Megaupload founder the thumbs-up on November 1, 2010. Dotcom believes that New Zealand was concerned he may have walked away from his application.

“This would have been of grave concern to the Government, which, at that time, was in negotiations with Hollywood lobby,” his affidavit reads.

“The last thing they would have needed at that delicate stage of the negotiations was for me to walk away from New Zealand and return to Hong Kong, where extradition would be more difficult. I believe that this concern is what prompted the ‘political pressure’ that led to my application finally being granted despite the presence of factors that would have caused anyone else’s application to have been rejected.”

Dotcom says that after being granted residency, there were signs things weren’t going to plan for him. The entrepreneur applied to buy his now-famous former mansion for NZ$37m, an application that was initially approved. However, after being passed to Simon Power, the application was denied.

“It would appear that, although my character was apparently good enough for me to be granted residence in November 2010, in July 2011 it was not considered good enough for me to buy property in New Zealand,” Dotcom notes.

“The Honourable Mr Power clearly did not want me purchasing $37 million of real estate, presumably because he knew that the United States was going to seek forfeiture of my assets and he did not want what was then the most expensive property in New Zealand being forfeited to the United States government.”

Of course, Dotcom concludes by highlighting the unlawful spying by New Zealand’s GCSB spy agency and the disproportionate use of force displayed by the police when they raided him in 2010 using dozens of armed officers. This, combined with all of the above, means that questions about his case must now be answered at the highest levels. With Obama in town, there’s no time like the present.

“As the evidence above demonstrates, this improper purpose which was then embraced by the New Zealand authorities, originated in the White House under the Obama administration. It is therefore necessary to examine Mr Obama in this proceeding,” Dotcom concludes.

Press blackouts aside, it appears that Obama has rather a lot of golf lined up for the coming days. Whether he’ll have any time to answer Dotcom’s questions is one thing but whether he’ll even be asked to is perhaps the most important point of all.

Deezer Piles Pressure on Pirates, Deezloader Reborn Throws in the Towel

Post Syndicated from Andy original https://torrentfreak.com/deezer-piles-pressure-on-pirates-deezloader-reborn-throws-in-the-towel-180315/

Spotify might grab most of the headlines in the world of music streaming but French firm Deezer is also growing in popularity.

Focused more on non-English speaking regions, the music service still has a massive selection of tens of millions of tracks. More importantly for pirates, it also has a loophole or two that allows users to permanently download songs from the service, a huge ‘selling’ point for the compulsive archiver.

One of the most popular third-party tools for achieving this was Deezloader but last year Deezer put pressure on its operators to cease-and-desist.

“On April 27, 2017 we received takedowns and threatened legal action from Deezer if we don’t shut down by April 29. So we decided to shut down Deezloader permanently,” the team announced.

Rather than kill the scene, the attack on Deezloader only seemed to spur things on. Many other apps underwent development in the months that followed but last December it became evident that Deezer (and probably the record labels supplying its content) were growing increasingly tired of these kinds of applications.

The company sent a wave of DMCA notices to developer platform GitHub, targeting several tools, claiming that they are “in total violation of our rights and of the rights of our music licensors.”

GitHub responded quickly by removing access to repositories referencing Deezloader, DeezerDownload, Deeze, Deezerio, Deezit, Deedown, and their associated forks. Deezer also reportedly modified its API, in order to stop or hinder apps already in existence.

However, pirates are a determined bunch and behind the scenes many sought to breathe new life into their projects, to maintain the flow of free music from Deezer. One of those that gained traction was the obviously-titled ‘Deezloader Reborn’ which enjoyed a new lease of life on both Github and Reddit after taking over from DeezLoader V2.3.1.

But in January 2018, Deezer turned up the pressure again, hitting Github with a wave (1,2) of takedown notices targeting various projects. On January 23, Deezer hit Deezloader Reborn itself with the notice detailed below.

The following project, identified in the paragraph below, makes available a hacked version of our Deezer application by describing methods to bypass Deezer’s security measures to unlawfully download its music catalogue, in total violation of our rights and of the rights of our music licensors (phonographic producers, performing artists, songwriters and composers):

https://github.com/ExtendLord/DeezLoader-Reborn

I therefore ask that you immediately take down the project corresponding to the URL above and all of the related forks by others members who have had access or even contributed to such projects.

Not only did Github comply with Deezer’s request, Reddit did too. According to a thread still listed on the site, Reddit removed a post about Deezloader Reborn following a copyright complaint from Deezer.

Two days later Deezer targeted similar projects on Github but by this time, Deezloader Reborn already had new plans. Speaking with TF, project developer ExtendLord said that he wouldn’t be shutting down but would continue on code repository Gitlab instead. Now, however, those plans have also come to an abrupt end after Gitlab took the page down.

Deezloader Reborn – gone from Gitlab

A copy of the page available on Archive.org shows Deezloader Reborn at version 3.0.5 with the ability to download music ready-tagged and in FLAC quality. Links to newer versions are being shared on Reddit but it appears there is no longer a central trusted source for the application.

There’s no official confirmation yet but it seems likely that Deezer was behind the Gitlab takedown. TorrentFreak has contacted ExtendLord who linked us to this page which states that “DeezLoader Reborn is no longer maintained due to DMCA. [Version] 3.1.0 is the last update, no more updates will be made.”

So, at least for now, it appears that Deezloader Reborn will go the way of various other Deezer-reliant applications. That won’t be the end of the story though, that’s a certainty.

Raspbian update: supporting different screen sizes

Post Syndicated from Simon Long original https://www.raspberrypi.org/blog/raspbian-update-screen-sizes/

You may have noticed that we released a updated Raspbian software image yesterday. While the main reason for the new image was to provide support for the new Raspberry Pi 3 Model B+, the image also includes, alongside the usual set of bug fixes and minor tweaks, one significant chunk of new functionality that is worth pointing out.

Updating Raspbian on your Raspberry Pi

How to update to the latest version of Raspbian on your Raspberry Pi.

Compatibility

As a software developer, one of the most awkward things to deal with is what is known as platform fragmentation: having to write code that works on all the different devices and configurations people use. In my spare time, I write applications for iOS, and this has become increasingly painful over the last few years. When I wrote my first iPhone application, it only had to work on the original iPhone, but nowadays any iOS application has to work across several models of iPhone and iPad (which all have different processors and screens), and also across the various releases of iOS. And that’s before you start to consider making your code run on Android as well…

Screenshot of clean Raspbian desktop

The good thing about developing for Raspberry Pi is that there is only a relatively small number of different models of Pi hardware. We try our best to make sure that, wherever possible, the Raspberry Pi Desktop software works on every model of Pi ever sold, and we’ve managed to do this for most of the software in the image. The only exceptions are some of the more recent applications like Chromium, which won’t run on the older ARM6 processors in the Pi 1 and the Pi Zero, and some applications that run very slowly due to needing more memory than the older platforms have.

Raspbian with different screen resolutions

But there is one area where we have no control over the hardware, and that is screen resolution. The HDMI port on the Pi supports a wide range of resolutions, and when you include the composite port and display connector as well, people can be using the desktop  on a huge number of different screen sizes.

Supporting a range of screen sizes is harder than you might think. One problem is that the Linux desktop environment is made up of a large selection of bits of software from various different developers, and not all of these support resizing. And the bits of software that do support resizing don’t all do it in the same way, so making everything resize at once can be awkward.

This is why one of the first things I did when I first started working on the desktop was to create the Appearance Settings application in order to bring a lot of the settings for things like font and icon sizes into one place. This avoids users having to tweak several configuration files whenever they wanted to change something.

Screenshot of appearance settings application in Raspbian

The Appearance Settings application was a good place to start regarding support of different screen sizes. One of the features I originally included was a button to set everything to a default value. This was really a default setting for screens of an average size, and the resulting defaults would not have worked that well on much smaller or much larger screens. Now, there is no longer a single defaults button, but a new Defaults tab with multiple options:

Screenshot of appearance settings application in Raspbian

These three options adjust font size, icon size, and various other settings to values which ought to work well on screens with a high or low resolution. (The For medium screens option has the same effect as the previous defaults button.) The results will not be perfect in all circumstances and for all applications — as mentioned above, there are many different components used to create the desktop, and some of them don’t provide any way of resizing what they draw. But using these options should set the most important parts of the desktop and installed applications, such as icons, fonts, and toolbars, to a suitable size.

Pixel doubling

We’ve added one other option for supporting high resolution screens. At the bottom of the System tab in the Raspberry Pi Configuration application, there is now an option for pixel doubling:

Screenshot of configuration application in Raspbian

We included this option to facilitate the use of the x86 version of Raspbian with ultra-high-resolution screens that have very small pixels, such as Apple’s Retina displays. When running our desktop on one of these, the tininess of the pixels made everything too small for comfortable use.

Enabling pixel doubling simply draws every pixel in the desktop as a 2×2 block of pixels on the screen, making everything exactly twice the size and resulting in a usable desktop on, for example, a MacBook Pro’s Retina display. We’ve included the option on the version of the desktop for the Pi as well, because we know that some people use their Pi with large-screen HDMI TVs.

As pixel doubling magnifies everything on the screen by a factor of two, it’s also a useful option for people with visual impairments.

How to update

As mentioned above, neither of these new functionalities is a perfect solution to dealing with different screen sizes, but we hope they will make life slightly easier for you if you’re trying to run the desktop on a small or large screen. The features are included in the new image we have just released to support the Pi 3B+. If you want to add them to your existing image, the standard upgrade from apt will do so. As shown in the video above, you can just open a terminal window and enter the following to update Raspbian:

sudo apt-get update
sudo apt-get dist-upgrade

As always, your feedback, either in comments here or on the forums, is very welcome.

Raspberry Jam Big Birthday Weekend 2018 roundup

Post Syndicated from Ben Nuttall original https://www.raspberrypi.org/blog/big-birthday-weekend-2018-roundup/

A couple of weekends ago, we celebrated our sixth birthday by coordinating more than 100 simultaneous Raspberry Jam events around the world. The Big Birthday Weekend was a huge success: our fantastic community organised Jams in 40 countries, covering six continents!

We sent the Jams special birthday kits to help them celebrate in style, and a video message featuring a thank you from Philip and Eben:

Raspberry Jam Big Birthday Weekend 2018

To celebrate the Raspberry Pi’s sixth birthday, we coordinated Raspberry Jams all over the world to take place over the Raspberry Jam Big Birthday Weekend, 3-4 March 2018. A massive thank you to everyone who ran an event and attended.

The Raspberry Jam photo booth

I put together code for a Pi-powered photo booth which overlaid the Big Birthday Weekend logo onto photos and (optionally) tweeted them. We included an arcade button in the Jam kits so they could build one — and it seemed to be quite popular. Some Jams put great effort into housing their photo booth:



Here are some of my favourite photo booth tweets:

The great Raspberry Jam bake-off

Traditionally, in the UK, people have a cake on their birthday. And we had a few! We saw (and tasted) a great selection of Pi-themed cakes and other baked goods throughout the weekend:






Raspberry Jams everywhere

We always say that every Jam is different, but there’s a common and recognisable theme amongst them. It was great to see so many different venues around the world filling up with like-minded Pi enthusiasts, Raspberry Jam–branded banners, and Raspberry Pi balloons!

Personally, I managed to get to three Jams over the weekend: two run by the same people who put on the first two Jams to ever take place, and also one brand-new one! The Preston Raspberry Jam team, who usually run their event on a Monday evening, wanted to do something extra special for the birthday, so they came up with the idea of putting on a Raspberry Jam Sandwich — on the Friday and Monday around the weekend! This meant I was able to visit them on Friday, then attend the Manchester Raspberry Jam on Saturday, and finally drop by the new Jam at Worksop College on my way home on Sunday.

HDD vs SSD: What Does the Future for Storage Hold?

Post Syndicated from Roderick Bauer original https://www.backblaze.com/blog/ssd-vs-hdd-future-of-storage/

SSD 60 TB drive

This is part one of a series. Use the Join button above to receive notification of future posts on this and other topics.

Customers frequently ask us whether and when we plan to move our cloud backup and data storage to SSDs (Solid-State Drives). That’s not a surprising question considering the many advantages SSDs have over magnetic platter type drives, also known as HDDs (Hard-Disk Drives).

We’re a large user of HDDs in our data centers (currently 100,000 hard drives holding over 500 petabytes of data). We want to provide the best performance, reliability, and economy for our cloud backup and cloud storage services, so we continually evaluate which drives to use for operations and in our data centers. While we use SSDs for some applications, which we’ll describe below, there are reasons why HDDs will continue to be the primary drives of choice for us and other cloud providers for the foreseeable future.

HDDs vs SSDs

HDD vs SSD

The laptop computer I am writing this on has a single 512GB SSD, which has become a common feature in higher end laptops. The SSD’s advantages for a laptop are easy to understand: they are smaller than an HDD, faster, quieter, last longer, and are not susceptible to vibration and magnetic fields. They also have much lower latency and access times.

Today’s typical online price for a 2.5” 512GB SSD is $140 to $170. The typical online price for a 3.5” 512 GB HDD is $44 to $65. That’s a pretty significant difference in price, but since the SSD helps make the laptop lighter, enables it to be more resistant to the inevitable shocks and jolts it will experience in daily use, and adds of benefits of faster booting, faster waking from sleep, and faster launching of applications and handling of big files, the extra cost for the SSD in this case is worth it.

Some of these SSD advantages, chiefly speed, also will apply to a desktop computer, so desktops are increasingly outfitted with SSDs, particularly to hold the operating system, applications, and data that is accessed frequently. Replacing a boot drive with an SSD has become a popular upgrade option to breathe new life into a computer, especially one that seems to take forever to boot or is used for notoriously slow-loading applications such as Photoshop.

We covered upgrading your computer with an SSD in our blog post SSD 101: How to Upgrade Your Computer With An SSD.

Data centers are an entirely different kettle of fish. The primary concerns for data center storage are reliability, storage density, and cost. While SSDs are strong in the first two areas, it’s the third where they are not yet competitive. At Backblaze we adopt higher density HDDs as they become available — we’re currently using both 10TB and 12TB drives (among other capacities) in our data centers. Higher density drives provide greater storage density per Storage Pod and Vault and reduce our overhead cost through less required maintenance and lower total power requirements. Comparable SSDs in those sizes would cost roughly $1,000 per terabyte, considerably higher than the corresponding HDD. Simply put, SSDs are not yet in the price range to make their use economical for the benefits they provide, which is the reason why we expect to be using HDDs as our primary storage media for the foreseeable future.

What Are HDDs?

HDDs have been around over 60 years since IBM introduced them in 1956. The first disk drive was the size of a car, stored a mere 3.75 megabytes, and cost $300,000 in today’s dollars.

IBM 350 Disk Storage System — 3.75MB in 1956

The 350 Disk Storage System was a major component of the IBM 305 RAMAC (Random Access Method of Accounting and Control) system, which was introduced in September 1956. It consisted of 40 platters and a dual read/write head on a single arm that moved up and down the stack of magnetic disk platters.

The basic mechanism of an HDD remains unchanged since then, though it has undergone continual refinement. An HDD uses magnetism to store data on a rotating platter. A read/write head is affixed to an arm that floats above the spinning platter reading and writing data. The faster the platter spins, the faster an HDD can perform. Typical laptop drives today spin at either 5400 RPM (revolutions per minute) or 7200 RPM, though some server-based platters spin at even higher speeds.

Exploded drawing of a hard drive

Exploded drawing of a hard drive

The platters inside the drives are coated with a magnetically sensitive film consisting of tiny magnetic grains. Data is recorded when a magnetic write-head flies just above the spinning disk; the write head rapidly flips the magnetization of one magnetic region of grains so that its magnetic pole points up or down, to encode a 1 or a 0 in binary code. If all this sounds like an HDD is vulnerable to shocks and vibration, you’d be right. They also are vulnerable to magnets, which is one way to destroy the data on an HDD if you’re getting rid of it.

The major advantage of an HDD is that it can store lots of data cheaply. One and two terabyte (1,024 and 2,048 gigabytes) hard drives are not unusual for a laptop these days, and 10TB and 12TB drives are now available for desktops and servers. Densities and rotation speeds continue to grow. However, if you compare the cost of common HDDs vs SSDs for sale online, the SSDs are roughly 3-5x the cost per gigabyte. So if you want cheap storage and lots of it, using a standard hard drive is definitely the more economical way to go.

What are the best uses for HDDs?

  • Disk arrays (NAS, RAID, etc.) where high capacity is needed
  • Desktops when low cost is priority
  • Media storage (photos, videos, audio not currently being worked on)
  • Drives with extreme number of reads and writes

What Are SSDs?

SSDs go back almost as far as HDDs, with the first semiconductor storage device compatible with a hard drive interface introduced in 1978, the StorageTek 4305.

Storage Technology 4305 SSD

The StorageTek was an SSD aimed at the IBM mainframe compatible market. The STC 4305 was seven times faster than IBM’s popular 2305 HDD system (and also about half the price). It consisted of a cabinet full of charge-coupled devices and cost $400,000 for 45MB capacity with throughput speeds up to 1.5 MB/sec.

SSDs are based on a type of non-volatile memory called NAND (named for the Boolean operator “NOT AND,” and one of two main types of flash memory). Flash memory stores data in individual memory cells, which are made of floating-gate transistors. Though they are semiconductor-based memory, they retain their information when no power is applied to them — a feature that’s obviously a necessity for permanent data storage.

Samsung SSD

Samsung SSD 850 Pro

Compared to an HDD, SSDs have higher data-transfer rates, higher areal storage density, better reliability, and much lower latency and access times. For most users, it’s the speed of an SSD that primarily attracts them. When discussing the speed of drives, what we are referring to is the speed at which they can read and write data.

For HDDs, the speed at which the platters spin strongly determines the read/write times. When data on an HDD is accessed, the read/write head must physically move to the location where the data was encoded on a magnetic section on the platter. If the file being read was written sequentially to the disk, it will be read quickly. As more data is written to the disk, however, it’s likely that the file will be written across multiple sections, resulting in fragmentation of the data. Fragmented data takes longer to read with an HDD as the read head has to move to different areas of the platter(s) to completely read all the data requested.

Because SSDs have no moving parts, they can operate at speeds far above those of a typical HDD. Fragmentation is not an issue for SSDs. Files can be written anywhere with little impact on read/write times, resulting in read times far faster than any HDD, regardless of fragmentation.

Samsung SSD 850 Pro (back)

Due to the way data is written and read to the drive, however, SSD cells can wear out over time. SSD cells push electrons through a gate to set its state. This process wears on the cell and over time reduces its performance until the SSD wears out. This effect takes a long time and SSDs have mechanisms to minimize this effect, such as the TRIM command. Flash memory writes an entire block of storage no matter how few pages within the block are updated. This requires reading and caching the existing data, erasing the block and rewriting the block. If an empty block is available, a write operation is much faster. The TRIM command, which must be supported in both the OS and the SSD, enables the OS to inform the drive which blocks are no longer needed. It allows the drive to erase the blocks ahead of time in order to make empty blocks available for subsequent writes.

The effect of repeated reading and erasing on an SSD is cumulative and an SSD can slow down and even display errors with age. It’s more likely, however, that the system using the SSD will be discarded for obsolescence before the SSD begins to display read/write errors. Hard drives eventually wear out from constant use as well, since they use physical recording methods, so most users won’t base their selection of an HDD or SSD drive based on expected longevity.

SSD internals

SSD circuit board

Overall, SSDs are considered far more durable than HDDs due to a lack of mechanical parts. The moving mechanisms within an HDD are susceptible to not only wear and tear over time, but to damage due to movement or forceful contact. If one were to drop a laptop with an HDD, there is a high likelihood that all those moving parts will collide, resulting in potential data loss and even destructive physical damage that could kill the HDD outright. SSDs have no moving parts so, while they hold the risk of a potentially shorter life span due to high use, they can survive the rigors we impose upon our portable devices and laptops.

What are the best uses for SSDs?

  • Notebooks, laptops, where performance, lightweight, areal storage density, resistance to shock and general ruggedness are desirable
  • Boot drives holding operating system and applications, which will speed up booting and application launching
  • Working files (media that is being edited: photos, video, audio, etc.)
  • Swap drives where SSD will speed up disk paging
  • Cache drives
  • Database servers
  • Revitalizing an older computer. If you’ve got a computer that seems slow to start up and slow to load applications and files, updating the boot drive with an SSD could make it seem, if not new, at least as if it just came back refreshed from spending some time on the beach.

Setting up bug bounties for success

Post Syndicated from Michal Zalewski original https://lcamtuf.blogspot.com/2018/03/setting-up-bug-bounties-for-success.html

Bug bounties end up in the news with some regularity, usually for the wrong reasons. I’ve been itching to write
about that for a while – but instead of dwelling on the mistakes of the bygone days, I figured it may be better to
talk about some of the ways to get vulnerability rewards right.

What do you get out of bug bounties?

There’s plenty of differing views, but I like to think of such programs
simply as a bid on researchers’ time. In the most basic sense, you get three benefits:

  • Improved ability to detect bugs in production before they become major incidents.
  • A comparatively unbiased feedback loop to help you prioritize and measure other security work.
  • A robust talent pipeline for when you need to hire.

What bug bounties don’t offer?

You don’t get anything resembling a comprehensive security program or a systematic assessment of your platforms.
Researchers end up looking for bugs that offer favorable effort-to-payoff ratios for their skills and given the
very imperfect information they have about your enterprise. In other words, you may end up with a hundred
people looking for XSS and just one person looking for RCE.

Your reward structure can steer them toward the targets and bugs you care about, but it’s difficult to fully
eliminate this inherent skew. There’s only so far you can jack up your top-tier rewards, and only so far you can
go lowering the bottom-tier ones.

Don’t you have to outcompete the black market to get all the “good” bugs?

There is a free market price discovery component to it all: if you’re not getting the engagement you
were hoping for, you should probably consider paying more.

That said, there are going to be researchers who’d rather hurt you than work for you, no matter how much you pay;
you don’t have to win them over, and you don’t have to outspend every authoritarian government or
every crime syndicate. A bug bounty is effective simply if it attracts enough eyeballs to make bugs statistically
harder to find, and reduces the useful lifespan of any zero-days in black market trade. Plus, most
researchers don’t want their work to be used to crack down on dissidents in Egypt or Vietnam.

Another factor is that you’re paying for different things: a black market buyer probably wants a reliable exploit
capable of delivering payloads, and then demands silence for months or years to come; a vendor-run
bug bounty program is usually perfectly happy with a reproducible crash and doesn’t mind a researcher blogging
about their work.

In fact, while money is important, you will probably find out that it’s not enough to retain your top talent;
many folks want bug bounties to be more than a business transaction, and find a lot of value in having a close
relationship with your security team, comparing notes, and growing together. Fostering that partnership can
be more important than adding another $10,000 to your top reward.

How do I prevent it all from going horribly wrong?

Bug bounties are an unfamiliar beast to most lawyers and PR folks, so it’s a natural to be wary and try to plan
for every eventuality with pages and pages of impenetrable rules and fine-print legalese.

This is generally unnecessary: there is a strong self-selection bias, and almost every participant in a
vulnerability reward program will be coming to you in good faith. The more friendly, forthcoming, and
approachable you seem, and the more you treat them like peers, the more likely it is for your relationship to stay
positive. On the flip side, there is no faster way to make enemies than to make a security researcher feel that they
are now talking to a lawyer or to the PR dept.

Most people have strong opinions on disclosure policies; instead of imposing your own views, strive to patch reported bugs
reasonably quickly, and almost every reporter will play along. Demand researchers to cancel conference appearances,
take down blog posts, or sign NDAs, and you will sooner or later end up in the news.

But what if that’s not enough?

As with any business endeavor, mistakes will happen; total risk avoidance is seldom the answer. Learn to sincerely
apologize for mishaps; it’s not a sign of weakness to say “sorry, we messed up”. And you will almost certainly not end
up in the courtroom for doing so.

It’s good to foster a healthy and productive relationship with the community, so that they come to your defense when
something goes wrong. Encouraging people to disclose bugs and talk about their experiences is one way of accomplishing that.

What about extortion?

You should structure your program to naturally discourage bad behavior and make it stand out like a sore thumb.
Require bona fide reports with complete technical details before any reward decision is made by a panel of named peers;
and make it clear that you never demand non-disclosure as a condition of getting a reward.

To avoid researchers accidentally putting themselves in awkward situations, have clear rules around data exfiltration
and lateral movement: assure them that you will always pay based on the worst-case impact of their findings; in exchange,
ask them to stop as soon as they get a shell and never access any data that isn’t their own.

So… are there any downsides?

Yep. Other than souring up your relationship with the community if you implement your program wrong, the other consideration
is that bug bounties tend to generate a lot of noise from well-meaning but less-skilled researchers.

When this happens, do not get frustrated and do not penalize such participants; instead, help them grow. Consider
publishing educational articles, giving advice on how to investigate and structure reports, or
offering free workshops every now and then.

The other downside is cost; although bug bounties tend to offer far more bang for your buck than your average penetration
test, they are more random. The annual expenses tend to be fairly predictable, but there is always
some possibility of having to pay multiple top-tier rewards in rapid succession. This is the kind of uncertainty that
many mid-level budget planners react badly to.

Finally, you need to be able to fix the bugs you receive. It would be nuts to prefer to not know about the
vulnerabilities in the first place – but once you invite the research, the clock starts ticking and you need to
ship fixes reasonably fast.

So… should I try it?

There are folks who enthusiastically advocate for bug bounties in every conceivable situation, and people who dislike them
with fierce passion; both sentiments are usually strongly correlated with the line of business they are in.

In reality, bug bounties are not a cure-all, and there are some ways to make them ineffectual or even dangerous.
But they are not as risky or expensive as most people suspect, and when done right, they can actually be fun for your
team, too. You won’t know for sure until you try.

Dotcom: Obama Admitted “Mistakes Were Made” in Megaupload Case

Post Syndicated from Andy original https://torrentfreak.com/dotcom-obama-admitted-mistakes-were-made-in-megaupload-case-180301/

When Megaupload was forcefully shut down in 2012, it initially appeared like ‘just’ another wave of copyright enforcement action by US authorities.

When additional details began to filter through, the reality of what had happened was nothing short of extraordinary.

Not only were large numbers of Megaupload servers and millions of dollars seized, but Kim Dotcom’s home in New Zealand was subjected to a military-style raid comprised of helicopters and dozens of heavily armed special tactics police. The whole thing was monitored live by the FBI.

Few people who watched the events of that now-infamous January day unfold came to the conclusion this was a routine copyright-infringement case. According to Kim Dotcom, whose life had just been turned upside down, something of this scale must’ve filtered down from the very top of the US government. It was hard to disagree.

At the time, Dotcom told TorrentFreak that then-Vice President Joe Biden directed attorney Neil MacBride to target the cloud storage site and ever since the Megaupload founder has leveled increasingly serious allegations at officials of the former government of Barack Obama.

For example, Dotcom says that since the US would have difficulty gaining access to him in his former home of Hong Kong, the government of New Zealand was persuaded to welcome him in, knowing they would eventually turn him over to the United States. More recently he’s been turning up the pressure again, such as a tweet on February 20th which cast more light on that process.

“Joe Biden had a White House meeting with an ‘extradition expert’ who worked for Hong Kong police and a handful of Hollywood executives to discuss my case. A week prior to this meeting Neil MacBride hand-delivered his action plan to Biden’s chief of staff, also at the White House,” Dotcom wrote.

But this claim is just the tip of an extremely large iceberg that’s involved illegal spying on Dotcom in New Zealand and a dizzying array of legal battles that are set to go on for years to come. But perhaps of most interest now is that rather than wilting away under the pressure, Dotcom appears to be just warming up.

A few hours ago Dotcom commented on an article published in The Hill which revealed that Barack Obama will visit New Zealand in March, possibly to celebrate the opening of Air New Zealand’s new route to the U.S.

Rather than expressing disappointment, the Megaupload founder seemed pleased that the former president would be touching down next month.

“Great. I’ll have a Court subpoena waiting for him in New Zealand,” Dotcom wrote.

But that was just a mere hors d’oeuvre, with the main course was yet to come. But come it did.

“A wealthy Asian Megaupload shareholder hired a friend of the Obamas to enquire about our case. This person was recommended by a member of the Chinese politburo ‘if you want to get to Obama directly’. We did,” Dotcom revealed.

Dotcom says he’ll release a transcript detailing what Obama told his friend on March 21 when Obama arrives in town but in the meantime, he offered another little taster.

“Mistakes were made. It hasn’t gone well,” Obama reportedly told the person reporting back to Megaupload. “It’s a problem. I’ll see to it after the election.”

Of course, Obama’s position after the election was much different to what had gone before, but that didn’t stop Dotcom’s associates infiltrating the process aimed at keeping the Democrats in power.

“Our friendly Obama contact smuggled an @EFF lawyer into a re-election fundraiser hosted by former Vice President Joe Biden,” he revealed.

“When Biden was asked about the Megaupload case he bragged that it was his case and that he ‘took care of it’,” which is what Dotcom has been claiming all along.

On March 21, when Obama lands in New Zealand, Dotcom says he’ll be waiting.

“I’m looking forward to @BarackObama providing some insight into the political dimension of the Megaupload case when he arrives in the New Zealand jurisdiction,” he teased.

Better get the popcorn ready….

Most Users of Exclusive Torrent Site Also Pay For Services Like Netflix or Prime

Post Syndicated from Andy original https://torrentfreak.com/most-users-of-exclusive-torrent-site-also-pay-for-services-like-netflix-or-prime-180225/

Despite a notable move to unlicensed streaming portals, millions of people still use public torrent sites every day to obtain the latest movies and TV shows. The process is easy, relatively quick, and free.

While these open-to-all platforms are undoubtedly popular, others prefer to use so-called ‘private trackers’, torrent sites with a private members’ club feel. Barriers to entry are much higher and many now require either an invitation from someone who is already a member or the passing of what amounts to an entrance exam.

Once accepted as a member, however, the rewards can be great. While public sites are a bit of a free-for-all, private trackers tend to take control of the content on offer, weeding out poor quality releases and ensuring only the best reach the user. Seeders are also plentiful, meaning that downloads complete in the fastest times.

On the flipside, some of the most exclusive trackers are almost impossible to join. A prime example is HDBits, a site that at last count wouldn’t accept more than 21,000 users yet keeps actual memberships down to around the 18,000 mark. Invites are extremely rare and those already inside tend to guard their accounts with their lives.

Second chances are rare on a site indexing more than 234,000 high-quality releases seeded by more than 950,000 peers and one of the broadest selection of Blu-ray offerings around. That’s what makes the results of a survey currently being carried out on the site even more remarkable.

In a poll launched by site staff, HDBits members – who by definition are already part of one of the most exclusive pirate haunts around – were asked whether they also pay for legal streaming services such as Netflix, Hulu or Amazon Prime.

At the time of writing more than 5,300 members have responded, with a surprising 57% (3,036) stating that they do indeed subscribe to at least one legal streaming service. When questioned on usage, more than a quarter of respondents said they actually use the legal service MORE than they use HDBits, which for a site of that caliber is quite a revelation.

HDBits poll – 57% of pirates pay for legal services

Keeping in mind that the site is creeping towards a quarter of a million torrents and is almost impossible to get into, it’s perhaps no surprise that unscrupulous people with access to an invitation on the site are selling them (against the site’s wishes) for up to $350 each online.

Let that sink in. For access to a pirate service, people are being asked to pay the equivalent of three years’ worth of Netflix subscriptions. Yet of those that are already members, more than a quarter use their Netflix, Hulu or Amazon Prime account more than they do HDBits. That’s a huge feather in the cap for the legal platforms that have nowhere near the selection that HDBits does.

One commenter in the HDBits survey thread gave his opinion on why Netflix might be winning the war.

“A thread several years ago like this was why I bought Netflix stock. Stunned not just that people here would actually pay for streaming 1 year old content in poor quality, but that almost everyone seemed to be doing it. If Netflix can win over [HDBits] then it is clearly a solution that will win over everyone,” he wrote.

Of course, perhaps the most important thing here is that even the most hardcore pirates have no problem purchasing official content, when the environment is right.

Unlike other surveys that can scare people away from admitting they’re breaking the law, most people on HDBits have nothing to hide from their peers. They know they’re pirates and aren’t afraid to admit it, yet almost 60% of them are happy to pay for legal content on top.

Entertainment companies often like to put pirates in one box and legitimate customers in another. Once again it’s now being made clear that such neatly defined barriers aren’t easy to come by.

Election Security

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/02/election_securi_2.html

I joined a letter supporting the Secure Elections Act (S. 2261):

The Secure Elections Act strikes a careful balance between state and federal action to secure American voting systems. The measure authorizes appropriation of grants to the states to take important and time-sensitive actions, including:

  • Replacing insecure paperless voting systems with new equipment that will process a paper ballot;
  • Implementing post-election audits of paper ballots or records to verify electronic tallies;

  • Conducting “cyber hygiene” scans and “risk and vulnerability” assessments and supporting state efforts to remediate identified vulnerabilities.

    The legislation would also create needed transparency and accountability in elections systems by establishing clear protocols for state and federal officials to communicate regarding security breaches and emerging threats.

The Challenges of Opening a Data Center — Part 1

This is part one of a series. The second part will be posted later this week. Use the Join button above to receive notification of future posts in this series.

Though most of us have never set foot inside of a data center, as citizens of a data-driven world we nonetheless depend on the services that data centers provide almost as much as we depend on a reliable water supply, the electrical grid, and the highway system. Every time we send a tweet, post to Facebook, check our bank balance or credit score, watch a YouTube video, or back up a computer to the cloud we are interacting with a data center.

In this series, The Challenges of Opening a Data Center, we’ll talk in general terms about the factors that an organization needs to consider when opening a data center and the challenges that must be met in the process. Many of the factors to consider will be similar for opening a private data center or seeking space in a public data center, but we’ll assume for the sake of this discussion that our needs are more modest than requiring a data center dedicated solely to our own use (i.e. we’re not Google, Facebook, or China Telecom).

Data center technology and management are changing rapidly, with new approaches to design and operation appearing every year. This means we won’t be able to cover everything happening in the world of data centers in our series, however, we hope our brief overview proves useful.

What is a Data Center?

A data center is the structure that houses a large group of networked computer servers typically used by businesses, governments, and organizations for the remote storage, processing, or distribution of large amounts of data.

While many organizations will have computing services in the same location as their offices that support their day-to-day operations, a data center is a structure dedicated to 24/7 large-scale data processing and handling.

Depending on how you define the term, there are anywhere from a half million data centers in the world to many millions. While it’s possible to say that an organization’s on-site servers and data storage can be called a data center, in this discussion we are using the term data center to refer to facilities that are expressly dedicated to housing computer systems and associated components, such as telecommunications and storage systems. The facility might be a private center, which is owned or leased by one tenant only, or a shared data center that offers what are called “colocation services,” and rents space, services, and equipment to multiple tenants in the center.

A large, modern data center operates around the clock, placing a priority on providing secure and uninterrrupted service, and generally includes redundant or backup power systems or supplies, redundant data communication connections, environmental controls, fire suppression systems, and numerous security devices. Such a center is an industrial-scale operation often using as much electricity as a small town.

Types of Data Centers

There are a number of ways to classify data centers according to how they will be used, whether they are owned or used by one or multiple organizations, whether and how they fit into a topology of other data centers; which technologies and management approaches they use for computing, storage, cooling, power, and operations; and increasingly visible these days: how green they are.

Data centers can be loosely classified into three types according to who owns them and who uses them.

Exclusive Data Centers are facilities wholly built, maintained, operated and managed by the business for the optimal operation of its IT equipment. Some of these centers are well-known companies such as Facebook, Google, or Microsoft, while others are less public-facing big telecoms, insurance companies, or other service providers.

Managed Hosting Providers are data centers managed by a third party on behalf of a business. The business does not own data center or space within it. Rather, the business rents IT equipment and infrastructure it needs instead of investing in the outright purchase of what it needs.

Colocation Data Centers are usually large facilities built to accommodate multiple businesses within the center. The business rents its own space within the data center and subsequently fills the space with its IT equipment, or possibly uses equipment provided by the data center operator.

Backblaze, for example, doesn’t own its own data centers but colocates in data centers owned by others. As Backblaze’s storage needs grow, Backblaze increases the space it uses within a given data center and/or expands to other data centers in the same or different geographic areas.

Availability is Key

When designing or selecting a data center, an organization needs to decide what level of availability is required for its services. The type of business or service it provides likely will dictate this. Any organization that provides real-time and/or critical data services will need the highest level of availability and redundancy, as well as the ability to rapidly failover (transfer operation to another center) when and if required. Some organizations require multiple data centers not just to handle the computer or storage capacity they use, but to provide alternate locations for operation if something should happen temporarily or permanently to one or more of their centers.

Organizations operating data centers that can’t afford any downtime at all will typically operate data centers that have a mirrored site that can take over if something happens to the first site, or they operate a second site in parallel to the first one. These data center topologies are called Active/Passive, and Active/Active, respectively. Should disaster or an outage occur, disaster mode would dictate immediately moving all of the primary data center’s processing to the second data center.

While some data center topologies are spread throughout a single country or continent, others extend around the world. Practically, data transmission speeds put a cap on centers that can be operated in parallel with the appearance of simultaneous operation. Linking two data centers located apart from each other — say no more than 60 miles to limit data latency issues — together with dark fiber (leased fiber optic cable) could enable both data centers to be operated as if they were in the same location, reducing staffing requirements yet providing immediate failover to the secondary data center if needed.

This redundancy of facilities and ensured availability is of paramount importance to those needing uninterrupted data center services.

LEED Certification

Leadership in Energy and Environmental Design (LEED) is a rating system devised by the United States Green Building Council (USGBC) for the design, construction, and operation of green buildings. Facilities can achieve ratings of certified, silver, gold, or platinum based on criteria within six categories: sustainable sites, water efficiency, energy and atmosphere, materials and resources, indoor environmental quality, and innovation and design.

Green certification has become increasingly important in data center design and operation as data centers require great amounts of electricity and often cooling water to operate. Green technologies can reduce costs for data center operation, as well as make the arrival of data centers more amenable to environmentally-conscious communities.

The ACT, Inc. data center in Iowa City, Iowa was the first data center in the U.S. to receive LEED-Platinum certification, the highest level available.

Factors to Consider When Selecting a Data Center

There are numerous factors to consider when deciding to build or to occupy space in a data center. Aspects such as proximity to available power grids, telecommunications infrastructure, networking services, transportation lines, and emergency services can affect costs, risk, security and other factors that need to be taken into consideration.

The size of the data center will be dictated by the business requirements of the owner or tenant. A data center can occupy one room of a building, one or more floors, or an entire building. Most of the equipment is often in the form of servers mounted in 19 inch rack cabinets, which are usually placed in single rows forming corridors (so-called aisles) between them. This allows staff access to the front and rear of each cabinet. Servers differ greatly in size from 1U servers (i.e. one “U” or “RU” rack unit measuring 44.50 millimeters or 1.75 inches), to Backblaze’s Storage Pod design that fits a 4U chassis, to large freestanding storage silos that occupy many square feet of floor space.

Location

Location will be one of the biggest factors to consider when selecting a data center and encompasses many other factors that should be taken into account, such as geological risks, neighboring uses, and even local flight paths. Access to suitable available power at a suitable price point is often the most critical factor and the longest lead time item, followed by broadband service availability.

With more and more data centers available providing varied levels of service and cost, the choices increase each year. Data center brokers can be employed to find a data center, just as one might use a broker for home or other commercial real estate.

Websites listing available colocation space, such as upstack.io, or entire data centers for sale or lease, are widely used. A common practice is for a customer to publish its data center requirements, and the vendors compete to provide the most attractive bid in a reverse auction.

Business and Customer Proximity

The center’s closeness to a business or organization may or may not be a factor in the site selection. The organization might wish to be close enough to manage the center or supervise the on-site staff from a nearby business location. The location of customers might be a factor, especially if data transmission speeds and latency are important, or the business or customers have regulatory, political, tax, or other considerations that dictate areas suitable or not suitable for the storage and processing of data.

Climate

Local climate is a major factor in data center design because the climatic conditions dictate what cooling technologies should be deployed. In turn this impacts uptime and the costs associated with cooling, which can total as much as 50% or more of a center’s power costs. The topology and the cost of managing a data center in a warm, humid climate will vary greatly from managing one in a cool, dry climate. Nevertheless, data centers are located in both extremely cold regions and extremely hot ones, with innovative approaches used in both extremes to maintain desired temperatures within the center.

Geographic Stability and Extreme Weather Events

A major obvious factor in locating a data center is the stability of the actual site as regards weather, seismic activity, and the likelihood of weather events such as hurricanes, as well as fire or flooding.

Backblaze’s Sacramento data center describes its location as one of the most stable geographic locations in California, outside fault zones and floodplains.

Sacramento Data Center

Sometimes the location of the center comes first and the facility is hardened to withstand anticipated threats, such as Equinix’s NAP of the Americas data center in Miami, one of the largest single-building data centers on the planet (six stories and 750,000 square feet), which is built 32 feet above sea level and designed to withstand category 5 hurricane winds.

Most data centers don’t have the extreme protection or history of the Bahnhof data center, which is located inside the ultra-secure former nuclear bunker Pionen, in Stockholm, Sweden. It is buried 100 feet below ground inside the White Mountains and secured behind 15.7 in. thick metal doors. It prides itself on its self-described “Bond villain” ambiance.

Usually, the data center owner or tenant will want to take into account the balance between cost and risk in the selection of a location. The Ideal quadrant below is obviously favored when making this compromise.

Cost vs Risk in selecting a data center

Cost = Construction/lease, power, bandwidth, cooling, labor, taxes
Risk = Environmental (seismic, weather, water, fire), political, economic

Risk mitigation also plays a strong role in pricing. The extent to which providers must implement special building techniques and operating technologies to protect the facility will affect price. When selecting a data center, organizations must make note of the data center’s certification level on the basis of regulatory requirements in the industry. These certifications can ensure that an organization is meeting necessary compliance requirements.

Power

Electrical power usually represents the largest cost in a data center. The cost a service provider pays for power will be affected by the source of the power, the regulatory environment, the facility size and the rate concessions, if any, offered by the utility. At higher level tiers, battery, generator, and redundant power grids are a required part of the picture.

Fault tolerance and power redundancy are absolutely necessary to maintain uninterrupted data center operation. Parallel redundancy is a safeguard to ensure that an uninterruptible power supply (UPS) system is in place to provide electrical power if necessary. The UPS system can be based on batteries, saved kinetic energy, or some type of generator using diesel or another fuel. The center will operate on the UPS system with another UPS system acting as a backup power generator. If a power outage occurs, the additional UPS system power generator is available.

Many data centers require the use of independent power grids, with service provided by different utility companies or services, to prevent against loss of electrical service no matter what the cause. Some data centers have intentionally located themselves near national borders so that they can obtain redundant power from not just separate grids, but from separate geopolitical sources.

Higher redundancy levels required by a company will of invariably lead to higher prices. If one requires high availability backed by a service-level agreement (SLA), one can expect to pay more than another company with less demanding redundancy requirements.
