Retrying Undelivered Voice Messages with Amazon Pinpoint

Post Syndicated from Heidi Gloudemans original https://aws.amazon.com/blogs/messaging-and-targeting/retrying-undelivered-voice-messages-with-amazon-pinpoint/

Note: This post was written by Murat Balkan, an AWS Senior Solutions Architect.


Many of our customers use voice notifications to deliver mission-critical and time-sensitive messages to their users. Customers often configure their systems to retry delivery when these voice messages aren’t delivered the first time around. Other customers set up their systems to fall back to another channel in this situation.

This blog post shows you how to retry the delivery of a voice message if the initial attempt wasn’t successful.

Architecture

By completing the steps in this post, you can create a system that uses the architecture illustrated in the following image:

 

First, a Lambda function calls the SendMessage operation in the Amazon Pinpoint API. The SendMessage operation then initiates a phone call to the recipient and generates a unique message ID, which is returned to the Lambda function. The Lambda function then adds this message ID to a DynamoDB table.

While Amazon Pinpoint attempts to deliver a message to a recipient, it emits several event records. These records indicate when the call is initiated, when the phone is ringing, when the call is answered, and so forth. Amazon Pinpoint publishes these events to an Amazon SNS topic. In this example, we’re only interested in the BUSY, FAILED, and NO_ANSWER event types, so we add some filtering criteria.

An Amazon SQS queue then subscribes to the Amazon SNS topic and monitors the incoming events. The Delivery Delay attribute of this queue is also set at the queue level. This configuration provides a back-off retry mechanism for failed voice messages.

When the Delivery Delay timer is reached, another Lambda function polls the queue and extracts the MessageId attribute from the polled message. It uses this attribute to locate the DynamoDB record for the original call. This record also tells us how many times Amazon Pinpoint has attempted to deliver the message.

The Lambda function compares the number of retries to a MAX_RETRY environment variable to determine whether it should attempt to send the message again.

Prerequisites

To start sending transactional voice messages, create an Amazon Pinpoint project and then request a phone number. Next, clone this GitHub repository to your local machine.

After you add a long code to your account, use AWS SAM to deploy the remaining parts of this serverless architecture. You provide the long number as an input parameter to this template.

The AWS SAM template creates the following resources:

  • A Lambda function (CallGenerator) that initiates a voice call using the Amazon Pinpoint API.
  • An Amazon SNS topic that collects state change events from Amazon Pinpoint.
  • An Amazon SQS queue that queues the messages.
  • A Lambda function (RetryCallGenerator) that polls the Amazon SQS queue and re-initiates the previously failed call attempt by calling the CallGenerator function.
  • A DynamoDB table that contains information about previous attempts to deliver the call.

The template also defines a custom Lambda resource, CustomResource, which creates a configuration set in Amazon Pinpoint. This configuration set specifies the events to send to Amazon SNS. A Lambda environment variable, CONFIG_SET_NAME, contains the name of the configuration set.

This architecture consists of two Lambda functions, which are represented as two different apps in the AWS SAM template. These functions are named CallGenerator and RetryCallGenerator. The CallGenerator function initiates the voice message with Amazon Pinpoint. The SendMessage API in Amazon Pinpoint returns a MessageId. The architecture uses this ID as a key to connect messages to the various events that they generate. The CallGenerator function also retains this ID in a DynamoDB table called call_attempts. The RetryCallGenerator function looks up the MessageId in the call_attempts table. If necessary, the function tries to send the message again by invoking the CallGenerator function.

 

Deploying and Testing

Start by downloading the template from the GitHub repository. AWS SAM requires you to specify an Amazon Simple Storage Service (Amazon S3) bucket to hold the deployment artifacts. If you haven’t already created a bucket for this purpose, create one now. The bucket should be reachable by a AWS Identity and Access Management (IAM) user.

At the command line, enter the following command to package the application:

sam package --template template.yaml --output-template-file output_template.yaml --s3-bucket BUCKET_NAME_HERE

In the preceding command, replace BUCKET_NAME_HERE with the name of the Amazon S3 bucket that should hold the deployment artifacts.

AWS SAM packages the application and copies it into the Amazon S3 bucket. This AWS SAM template requires you to specify three parameters: longCode, the phone number that’s used to make the outbound calls; maxRetry, which is used to set the MAX_RETRY environment variable for the RetryCallGenerator application; and retryDelaySeconds, which sets the delivery delay time for the Amazon SQS queue.

When the AWS SAM package command finishes running, enter the following command to deploy the package:

sam deploy --template-file output_template.yaml --stack-name blogstack --capabilities CAPABILITY_IAM --parameter-overrides maxRetry=2 longCode=LONG_CODE retryDelaySeconds=60

In the preceding command, replace LONG_CODE with the dedicated phone number that you acquired earlier.

When you run this command, AWS SAM shows the progress of the deployment. When the deployment finishes, you can test it by sending a sample event to the CallGenerator Lambda function. Use the following sample event to test the Lambda function:

{
"Message": "<speak>Thank you for visiting the AWS <emphasis>Messaging and Targeting Blog</emphasis>.</speak>",
"PhoneNumber": "DESTINATION_PHONE_NUMBER",
"RetryCount": 0
}

In the preceding event, replace DESTINATION_PHONE_NUMBER with the phone number to which you want to send a test message.

Important: Telecommunication providers take several steps to limit unsolicited voice messages. For example, providers in the United States only deliver a certain number of automated voice messages to each recipient per day. For this reason, you can only use Amazon Pinpoint to send 10 calls per day to each recipient. Keep this limit in mind during the testing process.

Conclusion

This architecture shows how Amazon Pinpoint can deliver state change events to Amazon SNS and how a serverless application can use it. You can adapt this architecture to apply to other use cases, such as call auditing, advanced call analytics and more.

Creating a Seamless Handoff Between Amazon Pinpoint and Amazon Connect

Your customers deserve to have helpful communications with your brand, regardless of the channel that you use to interact with them. There are many situations in which you might have to move customers from one channel to another—for example, when a customer is interacting with a chatbot over SMS, but their needs suddenly change to require voice assistance. To create a great customer experience, your communications with your customers should be seamless across all communication channels.

Welcome aboard Customer Obsessed Airlines

In this post, we look at a scenario that involves our fictitious airline, Customer Obsessed Airlines. Severe storms in one area of the country have caused Customer Obsessed Airlines to cancel a large number of flights. Customer Obsessed Airlines has to notify all of the affected customers of the cancellations right away. But most importantly, to keep customers as happy as possible in this unfortunate and unavoidable situation, Customer Obsessed Airlines has to make it easy for customers to rebook their flights.

Fortunately, Customer Obsessed Airlines has implemented the solution that’s outlined later in this post. This solution uses Amazon Pinpoint to send messages to a targeted segment of customers—in this case, the specific customers who were booked on the affected flights. Some of these customers might have straightforward travel itineraries that can simply be rebooked through interactions with a chatbot. Other customers who have more complex itineraries, or those who simply prefer to interact with a human over the phone, can be handed off to an agent in your call center.

About the solution

The solution that we’ll build to handle this scenario can be deployed in under an hour. The following diagram illustrates the interactions in this solution.

At a high level, this solution uses the following workflow:

  1. An event occurs. Automated impact analysis systems trigger the creation of custom segments—in this case, all passengers whose flights were cancelled.
  2. Amazon Pinpoint sends a message to the affected passengers through their preferred channels. Amazon Pinpoint supports the email, SMS, push, and voice channels, but in this example, we focus exclusively on SMS.
  3. Passengers who receive the message can respond. When they do, they interact with a chatbot that helps them book a different flight.
  4. If a passenger requests a live agent, or if their situation can’t be handled by a chatbot, then Amazon Pinpoint passes information about the customer’s situation and communication history to Amazon Connect. The passenger is entered into a queue. When the passenger reaches the front of the queue, they receive a phone call from an agent.
  5. After being re-booked, the passenger receives a written confirmation of the changes to their itinerary through their preferred channel. Passengers are also given the option of providing feedback on their interaction when the process is complete.

To build this solution, we use Amazon Pinpoint to segment our customers based on their attributes (such as which flight they’ve booked), and to deliver messages to those segments.

We also use Amazon Connect to manage the voice calling part of the solution, and Amazon Lex to power the chatbot. Finally, we connect these services using logic that’s defined in AWS Lambda functions.

Setting up the solution

Step 1: Set up Amazon Pinpoint and link it with Amazon Lex

The first step in setting up this solution is to create a new Amazon Pinpoint project and configure the SMS channel. When that’s done, you can create an Amazon Lex chatbot and link it to the Amazon Pinpoint project.

We described this process in detail in an earlier blog post. Complete the procedures in Create an SMS Chatbot with Amazon Pinpoint and Amazon Lex, and then proceed to step 2.

Step 2: Set up Amazon Connect and link it with your Amazon Lex chatbot

By completing step 1, we’ve created a system that can send messages to our passengers and receive messages from them. The next step is to create a way for passengers to communicate with our call center.

The Amazon Connect Administrator Guide provides instructions for linking an Amazon Lex bot to an Amazon Connect instance. For complete procedures, see Add an Amazon Lex Bot.

When you complete these procedures, link your Amazon Connect instance to the same Amazon Lex bot that you created in step 1. This step is intended to provide customers with a consistent, cohesive experience across channels.

Step 3: Set up an Amazon Connect callback queue and use Amazon Pinpoint keyword logic to trigger it

Now that we’ve configured Amazon Pinpoint and Amazon Connect, we can connect them.

Linking the two services makes it possible for passengers to request additional assistance. Traditionally, passengers in this situation would have to call a call center themselves and then wait on hold for an agent to become available. However, in this solution, our call center calls the passenger directly as soon as an agent is available. When the agent calls the passenger, the agent has all of the information about the passenger’s issue, as well as a transcript of the passenger’s interactions with your chatbot.

To implement an automatic callback mechanism, use the Amazon Pinpoint Connect Callback Requestor, which is available on the AWS GitHub page.

Next steps

By completing the preceding three steps, you can send messages to a subset of your users based on the criteria you choose and the type of message you want to send. Your customers can interact with your message by replying with questions. When they do, a chatbot responds intelligently and appropriately.

You can add to this solution by expanding it to cover other communication channels, such as push notifications. You can also automate the initial communication by integrating the solution with your systems of record.

We’re excited to see what you build using the solution that we outlined in this post. Let us know of your ideas and your successes in the comments.

Eavesdropping on SMS Messages inside Telco Networks

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2019/11/eavesdropping_o_8.html

Fireeye reports on a Chinese-sponsored espionage effort to eavesdrop on text messages:

FireEye Mandiant recently discovered a new malware family used by APT41 (a Chinese APT group) that is designed to monitor and save SMS traffic from specific phone numbers, IMSI numbers and keywords for subsequent theft. Named MESSAGETAP, the tool was deployed by APT41 in a telecommunications network provider in support of Chinese espionage efforts. APT41’s operations have included state-sponsored cyber espionage missions as well as financially-motivated intrusions. These operations have spanned from as early as 2012 to the present day. For an overview of APT41, see our August 2019 blog post or our full published report.

Yet another example that demonstrates why end-to-end message encryption is so important.

Perverse Vulnerability from Interaction between 2-Factor Authentication and iOS AutoFill

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/06/perverse_vulner.html

Apple is rolling out an iOS security usability feature called Security code AutoFill. The basic idea is that the OS scans incoming SMS messages for security codes and suggests them in AutoFill, so that people can use them without having to memorize or type them.

Sounds like a really good idea, but Andreas Gutmann points out an application where this could become a vulnerability: when authenticating transactions:

Transaction authentication, as opposed to user authentication, is used to attest the correctness of the intention of an action rather than just the identity of a user. It is most widely known from online banking, where it is an essential tool to defend against sophisticated attacks. For example, an adversary can try to trick a victim into transferring money to a different account than the one intended. To achieve this the adversary might use social engineering techniques such as phishing and vishing and/or tools such as Man-in-the-Browser malware.

Transaction authentication is used to defend against these adversaries. Different methods exist but in the one of relevance here — which is among the most common methods currently used — the bank will summarise the salient information of any transaction request, augment this summary with a TAN tailored to that information, and send this data to the registered phone number via SMS. The user, or bank customer in this case, should verify the summary and, if this summary matches with his or her intentions, copy the TAN from the SMS message into the webpage.

This new iOS feature creates problems for the use of SMS in transaction authentication. Applied to 2FA, the user would no longer need to open and read the SMS from which the code has already been conveniently extracted and presented. Unless this feature can reliably distinguish between OTPs in 2FA and TANs in transaction authentication, we can expect that users will also have their TANs extracted and presented without context of the salient information, e.g. amount and destination of the transaction. Yet, precisely the verification of this salient information is essential for security. Examples of where this scenario could apply include a Man-in-the-Middle attack on the user accessing online banking from their mobile browser, or where a malicious website or app on the user’s phone accesses the bank’s legitimate online banking service.

This is an interesting interaction between two security systems. Security code AutoFill eliminates the need for the user to view the SMS or memorize the one-time code. Transaction authentication assumes the user read and approved the additional information in the SMS message before using the one-time code.

Friday Squid Blogging: Do Cephalopods Contain Alien DNA?

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/06/friday_squid_bl_627.html

Maybe not DNA, but biological somethings.

Cause of Cambrian explosion — Terrestrial or Cosmic?“:

Abstract: We review the salient evidence consistent with or predicted by the Hoyle-Wickramasinghe (H-W) thesis of Cometary (Cosmic) Biology. Much of this physical and biological evidence is multifactorial. One particular focus are the recent studies which date the emergence of the complex retroviruses of vertebrate lines at or just before the Cambrian Explosion of ~500 Ma. Such viruses are known to be plausibly associated with major evolutionary genomic processes. We believe this coincidence is not fortuitous but is consistent with a key prediction of H-W theory whereby major extinction-diversification evolutionary boundaries coincide with virus-bearing cometary-bolide bombardment events. A second focus is the remarkable evolution of intelligent complexity (Cephalopods) culminating in the emergence of the Octopus. A third focus concerns the micro-organism fossil evidence contained within meteorites as well as the detection in the upper atmosphere of apparent incoming life-bearing particles from space. In our view the totality of the multifactorial data and critical analyses assembled by Fred Hoyle, Chandra Wickramasinghe and their many colleagues since the 1960s leads to a very plausible conclusion — life may have been seeded here on Earth by life-bearing comets as soon as conditions on Earth allowed it to flourish (about or just before 4.1 Billion years ago); and living organisms such as space-resistant and space-hardy bacteria, viruses, more complex eukaryotic cells, fertilised ova and seeds have been continuously delivered ever since to Earth so being one important driver of further terrestrial evolution which has resulted in considerable genetic diversity and which has led to the emergence of mankind.

Two commentaries.

This is almost certainly not true.

As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

Monitoring your Amazon SNS message filtering activity with Amazon CloudWatch

Post Syndicated from Rachel Richardson original https://aws.amazon.com/blogs/compute/monitoring-your-amazon-sns-message-filtering-activity-with-amazon-cloudwatch/

This post is courtesy of Otavio Ferreira, Manager, Amazon SNS, AWS Messaging.

Amazon SNS message filtering provides a set of string and numeric matching operators that allow each subscription to receive only the messages of interest. Hence, SNS message filtering can simplify your pub/sub messaging architecture by offloading the message filtering logic from your subscriber systems, as well as the message routing logic from your publisher systems.

After you set the subscription attribute that defines a filter policy, the subscribing endpoint receives only the messages that carry attributes matching this filter policy. Other messages published to the topic are filtered out for this subscription. In this way, the native integration between SNS and Amazon CloudWatch provides visibility into the number of messages delivered, as well as the number of messages filtered out.

CloudWatch metrics are captured automatically for you. To get started with SNS message filtering, see Filtering Messages with Amazon SNS.

Message Filtering Metrics

The following six CloudWatch metrics are relevant to understanding your SNS message filtering activity:

  • NumberOfMessagesPublished – Inbound traffic to SNS. This metric tracks all the messages that have been published to the topic.
  • NumberOfNotificationsDelivered – Outbound traffic from SNS. This metric tracks all the messages that have been successfully delivered to endpoints subscribed to the topic. A delivery takes place either when the incoming message attributes match a subscription filter policy, or when the subscription has no filter policy at all, which results in a catch-all behavior.
  • NumberOfNotificationsFilteredOut – This metric tracks all the messages that were filtered out because they carried attributes that didn’t match the subscription filter policy.
  • NumberOfNotificationsFilteredOut-NoMessageAttributes – This metric tracks all the messages that were filtered out because they didn’t carry any attributes at all and, consequently, didn’t match the subscription filter policy.
  • NumberOfNotificationsFilteredOut-InvalidAttributes – This metric keeps track of messages that were filtered out because they carried invalid or malformed attributes and, thus, didn’t match the subscription filter policy.
  • NumberOfNotificationsFailed – This last metric tracks all the messages that failed to be delivered to subscribing endpoints, regardless of whether a filter policy had been set for the endpoint. This metric is emitted after the message delivery retry policy is exhausted, and SNS stops attempting to deliver the message. At that moment, the subscribing endpoint is likely no longer reachable. For example, the subscribing SQS queue or Lambda function has been deleted by its owner. You may want to closely monitor this metric to address message delivery issues quickly.

Message filtering graphs

Through the AWS Management Console, you can compose graphs to display your SNS message filtering activity. The graph shows the number of messages published, delivered, and filtered out within the timeframe you specify (1h, 3h, 12h, 1d, 3d, 1w, or custom).

SNS message filtering for CloudWatch Metrics

To compose an SNS message filtering graph with CloudWatch:

  1. Open the CloudWatch console.
  2. Choose Metrics, SNS, All Metrics, and Topic Metrics.
  3. Select all metrics to add to the graph, such as:
    • NumberOfMessagesPublished
    • NumberOfNotificationsDelivered
    • NumberOfNotificationsFilteredOut
  4. Choose Graphed metrics.
  5. In the Statistic column, switch from Average to Sum.
  6. Title your graph with a descriptive name, such as “SNS Message Filtering”

After you have your graph set up, you may want to copy the graph link for bookmarking, emailing, or sharing with co-workers. You may also want to add your graph to a CloudWatch dashboard for easy access in the future. Both actions are available to you on the Actions menu, which is found above the graph.

Summary

SNS message filtering defines how SNS topics behave in terms of message delivery. By using CloudWatch metrics, you gain visibility into the number of messages published, delivered, and filtered out. This enables you to validate the operation of filter policies and more easily troubleshoot during development phases.

SNS message filtering can be implemented easily with existing AWS SDKs by applying message and subscription attributes across all SNS supported protocols (Amazon SQS, AWS Lambda, HTTP, SMS, email, and mobile push). CloudWatch metrics for SNS message filtering is available now, in all AWS Regions.

AWS IoT 1-Click – Use Simple Devices to Trigger Lambda Functions

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/aws-iot-1-click-use-simple-devices-to-trigger-lambda-functions/

We announced a preview of AWS IoT 1-Click at AWS re:Invent 2017 and have been refining it ever since, focusing on simplicity and a clean out-of-box experience. Designed to make IoT available and accessible to a broad audience, AWS IoT 1-Click is now generally available, along with new IoT buttons from AWS and AT&T.

I sat down with the dev team a month or two ago to learn about the service so that I could start thinking about my blog post. During the meeting they gave me a pair of IoT buttons and I started to think about some creative ways to put them to use. Here are a few that I came up with:

Help Request – Earlier this month I spent a very pleasant weekend at the HackTillDawn hackathon in Los Angeles. As the participants were hacking away, they occasionally had questions about AWS, machine learning, Amazon SageMaker, and AWS DeepLens. While we had plenty of AWS Solution Architects on hand (decked out in fashionable & distinctive AWS shirts for easy identification), I imagined an IoT button for each team. Pressing the button would alert the SA crew via SMS and direct them to the proper table.

Camera ControlTim Bray and I were in the AWS video studio, prepping for the first episode of Tim’s series on AWS Messaging. Minutes before we opened the Twitch stream I realized that we did not have a clean, unobtrusive way to ask the camera operator to switch to a closeup view. Again, I imagined that a couple of IoT buttons would allow us to make the request.

Remote Dog Treat Dispenser – My dog barks every time a stranger opens the gate in front of our house. While it is great to have confirmation that my Ring doorbell is working, I would like to be able to press a button and dispense a treat so that Luna stops barking!

Homes, offices, factories, schools, vehicles, and health care facilities can all benefit from IoT buttons and other simple IoT devices, all managed using AWS IoT 1-Click.

All About AWS IoT 1-Click
As I said earlier, we have been focusing on simplicity and a clean out-of-box experience. Here’s what that means:

Architects can dream up applications for inexpensive, low-powered devices.

Developers don’t need to write any device-level code. They can make use of pre-built actions, which send email or SMS messages, or write their own custom actions using AWS Lambda functions.

Installers don’t have to install certificates or configure cloud endpoints on newly acquired devices, and don’t have to worry about firmware updates.

Administrators can monitor the overall status and health of each device, and can arrange to receive alerts when a device nears the end of its useful life and needs to be replaced, using a single interface that spans device types and manufacturers.

I’ll show you how easy this is in just a moment. But first, let’s talk about the current set of devices that are supported by AWS IoT 1-Click.

Who’s Got the Button?
We’re launching with support for two types of buttons (both pictured above). Both types of buttons are pre-configured with X.509 certificates, communicate to the cloud over secure connections, and are ready to use.

The AWS IoT Enterprise Button communicates via Wi-Fi. It has a 2000-click lifetime, encrypts outbound data using TLS, and can be configured using BLE and our mobile app. It retails for $19.99 (shipping and handling not included) and can be used in the United States, Europe, and Japan.

The AT&T LTE-M Button communicates via the LTE-M cellular network. It has a 1500-click lifetime, and also encrypts outbound data using TLS. The device and the bundled data plan is available an an introductory price of $29.99 (shipping and handling not included), and can be used in the United States.

We are very interested in working with device manufacturers in order to make even more shapes, sizes, and types of devices (badge readers, asset trackers, motion detectors, and industrial sensors, to name a few) available to our customers. Our team will be happy to tell you about our provisioning tools and our facility for pushing OTA (over the air) updates to large fleets of devices; you can contact them at [email protected].

AWS IoT 1-Click Concepts
I’m eager to show you how to use AWS IoT 1-Click and the buttons, but need to introduce a few concepts first.

Device – A button or other item that can send messages. Each device is uniquely identified by a serial number.

Placement Template – Describes a like-minded collection of devices to be deployed. Specifies the action to be performed and lists the names of custom attributes for each device.

Placement – A device that has been deployed. Referring to placements instead of devices gives you the freedom to replace and upgrade devices with minimal disruption. Each placement can include values for custom attributes such as a location (“Building 8, 3rd Floor, Room 1337”) or a purpose (“Coffee Request Button”).

Action – The AWS Lambda function to invoke when the button is pressed. You can write a function from scratch, or you can make use of a pair of predefined functions that send an email or an SMS message. The actions have access to the attributes; you can, for example, send an SMS message with the text “Urgent need for coffee in Building 8, 3rd Floor, Room 1337.”

Getting Started with AWS IoT 1-Click
Let’s set up an IoT button using the AWS IoT 1-Click Console:

If I didn’t have any buttons I could click Buy devices to get some. But, I do have some, so I click Claim devices to move ahead. I enter the device ID or claim code for my AT&T button and click Claim (I can enter multiple claim codes or device IDs if I want):

The AWS buttons can be claimed using the console or the mobile app; the first step is to use the mobile app to configure the button to use my Wi-Fi:

Then I scan the barcode on the box and click the button to complete the process of claiming the device. Both of my buttons are now visible in the console:

I am now ready to put them to use. I click on Projects, and then Create a project:

I name and describe my project, and click Next to proceed:

Now I define a device template, along with names and default values for the placement attributes. Here’s how I set up a device template (projects can contain several, but I just need one):

The action has two mandatory parameters (phone number and SMS message) built in; I add three more (Building, Room, and Floor) and click Create project:

I’m almost ready to ask for some coffee! The next step is to associate my buttons with this project by creating a placement for each one. I click Create placements to proceed. I name each placement, select the device to associate with it, and then enter values for the attributes that I established for the project. I can also add additional attributes that are peculiar to this placement:

I can inspect my project and see that everything looks good:

I click on the buttons and the SMS messages appear:

I can monitor device activity in the AWS IoT 1-Click Console:

And also in the Lambda Console:

The Lambda function itself is also accessible, and can be used as-is or customized:

As you can see, this is the code that lets me use {{*}}include all of the placement attributes in the message and {{Building}} (for example) to include a specific placement attribute.

Now Available
I’ve barely scratched the surface of this cool new service and I encourage you to give it a try (or a click) yourself. Buy a button or two, build something cool, and let me know all about it!

Pricing is based on the number of enabled devices in your account, measured monthly and pro-rated for partial months. Devices can be enabled or disabled at any time. See the AWS IoT 1-Click Pricing page for more info.

Ray Ozzie’s Encryption Backdoor

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/05/ray_ozzies_encr.html

Last month, Wired published a long article about Ray Ozzie and his supposed new scheme for adding a backdoor in encrypted devices. It’s a weird article. It paints Ozzie’s proposal as something that “attains the impossible” and “satisfies both law enforcement and privacy purists,” when (1) it’s barely a proposal, and (2) it’s essentially the same key escrow scheme we’ve been hearing about for decades.

Basically, each device has a unique public/private key pair and a secure processor. The public key goes into the processor and the device, and is used to encrypt whatever user key encrypts the data. The private key is stored in a secure database, available to law enforcement on demand. The only other trick is that for law enforcement to use that key, they have to put the device in some sort of irreversible recovery mode, which means it can never be used again. That’s basically it.

I have no idea why anyone is talking as if this were anything new. Several cryptographers have already explained why this key escrow scheme is no better than any other key escrow scheme. The short answer is (1) we won’t be able to secure that database of backdoor keys, (2) we don’t know how to build the secure coprocessor the scheme requires, and (3) it solves none of the policy problems around the whole system. This is the typical mistake non-cryptographers make when they approach this problem: they think that the hard part is the cryptography to create the backdoor. That’s actually the easy part. The hard part is ensuring that it’s only used by the good guys, and there’s nothing in Ozzie’s proposal that addresses any of that.

I worry that this kind of thing is damaging in the long run. There should be some rule that any backdoor or key escrow proposal be a fully specified proposal, not just some cryptography and hand-waving notions about how it will be used in practice. And before it is analyzed and debated, it should have to satisfy some sort of basic security analysis. Otherwise, we’ll be swatting pseudo-proposals like this one, while those on the other side of this debate become increasingly convinced that it’s possible to design one of these things securely.

Already people are using the National Academies report on backdoors for law enforcement as evidence that engineers are developing workable and secure backdoors. Writing in Lawfare, Alan Z. Rozenshtein claims that the report — and a related New York Times story — “undermine the argument that secure third-party access systems are so implausible that it’s not even worth trying to develop them.” Susan Landau effectively corrects this misconception, but the damage is done.

Here’s the thing: it’s not hard to design and build a backdoor. What’s hard is building the systems — both technical and procedural — around them. Here’s Rob Graham:

He’s only solving the part we already know how to solve. He’s deliberately ignoring the stuff we don’t know how to solve. We know how to make backdoors, we just don’t know how to secure them.

A bunch of us cryptographers have already explained why we don’t think this sort of thing will work in the foreseeable future. We write:

Exceptional access would force Internet system developers to reverse “forward secrecy” design practices that seek to minimize the impact on user privacy when systems are breached. The complexity of today’s Internet environment, with millions of apps and globally connected services, means that new law enforcement requirements are likely to introduce unanticipated, hard to detect security flaws. Beyond these and other technical vulnerabilities, the prospect of globally deployed exceptional access systems raises difficult problems about how such an environment would be governed and how to ensure that such systems would respect human rights and the rule of law.

Finally, Matthew Green:

The reason so few of us are willing to bet on massive-scale key escrow systems is that we’ve thought about it and we don’t think it will work. We’ve looked at the threat model, the usage model, and the quality of hardware and software that exists today. Our informed opinion is that there’s no detection system for key theft, there’s no renewability system, HSMs are terrifically vulnerable (and the companies largely staffed with ex-intelligence employees), and insiders can be suborned. We’re not going to put the data of a few billion people on the line an environment where we believe with high probability that the system will fail.

EDITED TO ADD (5/14): An analysis of the proposal.

Secure Build with AWS CodeBuild and LayeredInsight

Post Syndicated from Asif Khan original https://aws.amazon.com/blogs/devops/secure-build-with-aws-codebuild-and-layeredinsight/

This post is written by Asif Awan, Chief Technology Officer of Layered InsightSubin Mathew – Software Development Manager for AWS CodeBuild, and Asif Khan – Solutions Architect

Enterprises adopt containers because they recognize the benefits: speed, agility, portability, and high compute density. They understand how accelerating application delivery and deployment pipelines makes it possible to rapidly slipstream new features to customers. Although the benefits are indisputable, this acceleration raises concerns about security and corporate compliance with software governance. In this blog post, I provide a solution that shows how Layered Insight, the pioneer and global leader in container-native application protection, can be used with seamless application build and delivery pipelines like those available in AWS CodeBuild to address these concerns.

Layered Insight solutions

Layered Insight enables organizations to unify DevOps and SecOps by providing complete visibility and control of containerized applications. Using the industry’s first embedded security approach, Layered Insight solves the challenges of container performance and protection by providing accurate insight into container images, adaptive analysis of running containers, and automated enforcement of container behavior.

 

AWS CodeBuild

AWS CodeBuild is a fully managed build service that compiles source code, runs tests, and produces software packages that are ready to deploy. With CodeBuild, you don’t need to provision, manage, and scale your own build servers. CodeBuild scales continuously and processes multiple builds concurrently, so your builds are not left waiting in a queue. You can get started quickly by using prepackaged build environments, or you can create custom build environments that use your own build tools.

 

Problem Definition

Security and compliance concerns span the lifecycle of application containers. Common concerns include:

Visibility into the container images. You need to verify the software composition information of the container image to determine whether known vulnerabilities associated with any of the software packages and libraries are included in the container image.

Governance of container images is critical because only certain open source packages/libraries, of specific versions, should be included in the container images. You need support for mechanisms for blacklisting all container images that include a certain version of a software package/library, or only allowing open source software that come with a specific type of license (such as Apache, MIT, GPL, and so on). You need to be able to address challenges such as:

·       Defining the process for image compliance policies at the enterprise, department, and group levels.

·       Preventing the images that fail the compliance checks from being deployed in critical environments, such as staging, pre-prod, and production.

Visibility into running container instances is critical, including:

·       CPU and memory utilization.

·       Security of the build environment.

·       All activities (system, network, storage, and application layer) of the application code running in each container instance.

Protection of running container instances that is:

·       Zero-touch to the developers (not an SDK-based approach).

·       Zero touch to the DevOps team and doesn’t limit the portability of the containerized application.

·       This protection must retain the option to switch to a different container stack or orchestration layer, or even to a different Container as a Service (CaaS ).

·       And it must be a fully automated solution to SecOps, so that the SecOps team doesn’t have to manually analyze and define detailed blacklist and whitelist policies.

 

Solution Details

In AWS CodeCommit, we have three projects:
●     “Democode” is a simple Java application, with one buildspec to build the app into a Docker container (run by build-demo-image CodeBuild project), and another to instrument said container (instrument-image CodeBuild project). The resulting container is stored in ECR repo javatestasjavatest:20180415-layered. This instrumented container is running in AWS Fargate cluster demo-java-appand can be seen in the Layered Insight runtime console as the javatestapplication in us-east-1.
●     aws-codebuild-docker-imagesis a clone of the official aws-codebuild-docker-images repo on GitHub . This CodeCommit project is used by the build-python-builder CodeBuild project to build the python 3.3.6 codebuild image and is stored at the codebuild-python ECR repo. We then manually instructed the Layered Insight console to instrument the image.
●     scan-java-imagecontains just a buildspec.yml file. This file is used by the scan-java-image CodeBuild project to instruct Layered Assessment to perform a vulnerability scan of the javatest container image built previously, and then run the scan results through a compliance policy that states there should be no medium vulnerabilities. This build fails — but in this case that is a success: the scan completes successfully, but compliance fails as there are medium-level issues found in the scan.

This build is performed using the instrumented version of the Python 3.3.6 CodeBuild image, so the activity of the processes running within the build are recorded each time within the LI console.

Build container image

Create or use a CodeCommit project with your application. To build this image and store it in Amazon Elastic Container Registry (Amazon ECR), add a buildspec file to the project and build a container image and create a CodeBuild project.

Scan container image

Once the image is built, create a new buildspec in the same project or a new one that looks similar to below (update ECR URL as necessary):

version: 0.2
phases:
  pre_build:
    commands:
      - echo Pulling down LI Scan API client scripts
      - git clone https://github.com/LayeredInsight/scan-api-example-python.git
      - echo Setting up LI Scan API client
      - cd scan-api-example-python
      - pip install layint_scan_api
      - pip install -r requirements.txt
  build:
    commands:
      - echo Scanning container started on `date`
      - IMAGEID=$(./li_add_image --name <aws-region>.amazonaws.com/javatest:20180415)
      - ./li_wait_for_scan -v --imageid $IMAGEID
      - ./li_run_image_compliance -v --imageid $IMAGEID --policyid PB15260f1acb6b2aa5b597e9d22feffb538256a01fbb4e5a95

Add the buildspec file to the git repo, push it, and then build a CodeBuild project using with the instrumented Python 3.3.6 CodeBuild image at <aws-region>.amazonaws.com/codebuild-python:3.3.6-layered. Set the following environment variables in the CodeBuild project:
●     LI_APPLICATIONNAME – name of the build to display
●     LI_LOCATION – location of the build project to display
●     LI_API_KEY – ApiKey:<key-name>:<api-key>
●     LI_API_HOST – location of the Layered Insight API service

Instrument container image

Next, to instrument the new container image:

  1. In the Layered Insight runtime console, ensure that the ECR registry and credentials are defined (click the Setup icon and the ‘+’ sign on the top right of the screen to add a new container registry). Note the name given to the registry in the console, as this needs to be referenced in the li_add_imagecommand in the script, below.
  2. Next, add a new buildspec (with a new name) to the CodeCommit project, such as the one shown below. This code will download the Layered Insight runtime client, and use it to instruct the Layered Insight service to instrument the image that was just built:
    version: 0.2
    phases:
    pre_build:
    commands:
    echo Pulling down LI API Runtime client scripts
    git clone https://github.com/LayeredInsight/runtime-api-example-python
    echo Setting up LI API client
    cd runtime-api-example-python
    pip install layint-runtime-api
    pip install -r requirements.txt
    build:
    commands:
    echo Instrumentation started on `date`
    ./li_add_image --registry "Javatest ECR" --name IMAGE_NAME:TAG --description "IMAGE DESCRIPTION" --policy "Default Policy" --instrument --wait --verbose
  3. Commit and push the new buildspec file.
  4. Going back to CodeBuild, create a new project, with the same CodeCommit repo, but this time select the new buildspec file. Use a Python 3.3.6 builder – either the AWS or LI Instrumented version.
  5. Click Continue
  6. Click Save
  7. Run the build, again on the master branch.
  8. If everything runs successfully, a new image should appear in the ECR registry with a -layered suffix. This is the instrumented image.

Run instrumented container image

When the instrumented container is now run — in ECS, Fargate, or elsewhere — it will log data back to the Layered Insight runtime console. It’s appearance in the console can be modified by setting the LI_APPLICATIONNAME and LI_LOCATION environment variables when running the container.

Conclusion

In the above blog we have provided you steps needed to embed governance and runtime security in your build pipelines running on AWS CodeBuild using Layered Insight.

The Amazon SES Blog is now the AWS Messaging and Targeting Blog

Post Syndicated from Brent Meyer original https://aws.amazon.com/blogs/messaging-and-targeting/the-amazon-ses-blog-is-now-the-aws-messaging-and-targeting-blog/

Regular visitors to this blog may have noticed that its name has changed from the Amazon SES Blog to the AWS Messaging and Targeting Blog. The Amazon SES team has been working closely with the Amazon Pinpoint team in recent months, so we decided to create a single source of information for both products.

If you’re a dedicated Amazon SES user, don’t worry—Amazon SES isn’t going anywhere. However, as the goals of our two teams started to overlap more and more, we realized that we had lots of ideas for blog posts that would be relevant to users of both products.

If you’re not familiar with Amazon Pinpoint yet, allow us to make a brief introduction. Amazon Pinpoint was originally created to help mobile app developers analyze the ways that their customers used their apps, and to send mobile push messages to those users. Over time, the capabilities of Amazon Pinpoint grew to include the ability to send transactional messages (such as order confirmations, welcome messages, and one-time passwords), segment your audience, schedule campaign execution, and send messages using other channels (including SMS and email). In short, Amazon Pinpoint helps you deliver the right message to the right customers at the right time using the right channel.

In the past, this blog focused mainly on providing information about new features and common issues. Our new blog will include that same information, as well as practical tips, industry best practices, and the exciting things our customers have done using Amazon SES and Amazon Pinpoint. We hope you enjoy it!

If you have any questions, or if there’s anything you’d like to see us cover in the blog, please let us know in the comments section.

AWS Certificate Manager Launches Private Certificate Authority

Post Syndicated from Randall Hunt original https://aws.amazon.com/blogs/aws/aws-certificate-manager-launches-private-certificate-authority/

Today we’re launching a new feature for AWS Certificate Manager (ACM), Private Certificate Authority (CA). This new service allows ACM to act as a private subordinate CA. Previously, if a customer wanted to use private certificates, they needed specialized infrastructure and security expertise that could be expensive to maintain and operate. ACM Private CA builds on ACM’s existing certificate capabilities to help you easily and securely manage the lifecycle of your private certificates with pay as you go pricing. This enables developers to provision certificates in just a few simple API calls while administrators have a central CA management console and fine grained access control through granular IAM policies. ACM Private CA keys are stored securely in AWS managed hardware security modules (HSMs) that adhere to FIPS 140-2 Level 3 security standards. ACM Private CA automatically maintains certificate revocation lists (CRLs) in Amazon Simple Storage Service (S3) and lets administrators generate audit reports of certificate creation with the API or console. This service is packed full of features so let’s jump in and provision a CA.

Provisioning a Private Certificate Authority (CA)

First, I’ll navigate to the ACM console in my region and select the new Private CAs section in the sidebar. From there I’ll click Get Started to start the CA wizard. For now, I only have the option to provision a subordinate CA so we’ll select that and use my super secure desktop as the root CA and click Next. This isn’t what I would do in a production setting but it will work for testing out our private CA.

Now, I’ll configure the CA with some common details. The most important thing here is the Common Name which I’ll set as secure.internal to represent my internal domain.

Now I need to choose my key algorithm. You should choose the best algorithm for your needs but know that ACM has a limitation today that it can only manage certificates that chain up to to RSA CAs. For now, I’ll go with RSA 2048 bit and click Next.

In this next screen, I’m able to configure my certificate revocation list (CRL). CRLs are essential for notifying clients in the case that a certificate has been compromised before certificate expiration. ACM will maintain the revocation list for me and I have the option of routing my S3 bucket to a custome domain. In this case I’ll create a new S3 bucket to store my CRL in and click Next.

Finally, I’ll review all the details to make sure I didn’t make any typos and click Confirm and create.

A few seconds later and I’m greeted with a fancy screen saying I successfully provisioned a certificate authority. Hooray! I’m not done yet though. I still need to activate my CA by creating a certificate signing request (CSR) and signing that with my root CA. I’ll click Get started to begin that process.

Now I’ll copy the CSR or download it to a server or desktop that has access to my root CA (or potentially another subordinate – so long as it chains to a trusted root for my clients).

Now I can use a tool like openssl to sign my cert and generate the certificate chain.


$openssl ca -config openssl_root.cnf -extensions v3_intermediate_ca -days 3650 -notext -md sha256 -in csr/CSR.pem -out certs/subordinate_cert.pem
Using configuration from openssl_root.cnf
Enter pass phrase for /Users/randhunt/dev/amzn/ca/private/root_private_key.pem:
Check that the request matches the signature
Signature ok
The Subject's Distinguished Name is as follows
stateOrProvinceName   :ASN.1 12:'Washington'
localityName          :ASN.1 12:'Seattle'
organizationName      :ASN.1 12:'Amazon'
organizationalUnitName:ASN.1 12:'Engineering'
commonName            :ASN.1 12:'secure.internal'
Certificate is to be certified until Mar 31 06:05:30 2028 GMT (3650 days)
Sign the certificate? [y/n]:y


1 out of 1 certificate requests certified, commit? [y/n]y
Write out database with 1 new entries
Data Base Updated

After that I’ll copy my subordinate_cert.pem and certificate chain back into the console. and click Next.

Finally, I’ll review all the information and click Confirm and import. I should see a screen like the one below that shows my CA has been activated successfully.

Now that I have a private CA we can provision private certificates by hopping back to the ACM console and creating a new certificate. After clicking create a new certificate I’ll select the radio button Request a private certificate then I’ll click Request a certificate.

From there it’s just similar to provisioning a normal certificate in ACM.

Now I have a private certificate that I can bind to my ELBs, CloudFront Distributions, API Gateways, and more. I can also export the certificate for use on embedded devices or outside of ACM managed environments.

Available Now
ACM Private CA is a service in and of itself and it is packed full of features that won’t fit into a blog post. I strongly encourage the interested readers to go through the developer guide and familiarize themselves with certificate based security. ACM Private CA is available in in US East (N. Virginia), US East (Ohio), US West (Oregon), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Canada (Central), EU (Frankfurt) and EU (Ireland). Private CAs cost $400 per month (prorated) for each private CA. You are not charged for certificates created and maintained in ACM but you are charged for certificates where you have access to the private key (exported or created outside of ACM). The pricing per certificate is tiered starting at $0.75 per certificate for the first 1000 certificates and going down to $0.001 per certificate after 10,000 certificates.

I’m excited to see administrators and developers take advantage of this new service. As always please let us know what you think of this service on Twitter or in the comments below.

Security of Cloud HSMBackups

Post Syndicated from Balaji Iyer original https://aws.amazon.com/blogs/architecture/security-of-cloud-hsmbackups/

Today, our customers use AWS CloudHSM to meet corporate, contractual and regulatory compliance requirements for data security by using dedicated Hardware Security Module (HSM) instances within the AWS cloud. CloudHSM delivers all the benefits of traditional HSMs including secure generation, storage, and management of cryptographic keys used for data encryption that are controlled and accessible only by you.

As a managed service, it automates time-consuming administrative tasks such as hardware provisioning, software patching, high availability, backups and scaling for your sensitive and regulated workloads in a cost-effective manner. Backup and restore functionality is the core building block enabling scalability, reliability and high availability in CloudHSM.

You should consider using AWS CloudHSM if you require:

  • Keys stored in dedicated, third-party validated hardware security modules under your exclusive control
  • FIPS 140-2 compliance
  • Integration with applications using PKCS#11, Java JCE, or Microsoft CNG interfaces
  • High-performance in-VPC cryptographic acceleration (bulk crypto)
  • Financial applications subject to PCI regulations
  • Healthcare applications subject to HIPAA regulations
  • Streaming video solutions subject to contractual DRM requirements

We recently released a whitepaper, “Security of CloudHSM Backups” that provides in-depth information on how backups are protected in all three phases of the CloudHSM backup lifecycle process: Creation, Archive, and Restore.

[$] Read-only dynamic data

Post Syndicated from corbet original https://lwn.net/Articles/750215/rss

Kernel developers go to some lengths to mark read-only data so that it can
be protected by the system’s memory-management unit.
Memory that cannot be changed cannot be altered by an attacker to corrupt the
system. But the kernel’s mechanisms for managing read-only memory do not
work for memory that must be initialized after the initial system bootstrap
has completed. A patch set from Igor Stoppa
seeks to change that situation by creating a new API just for
late-initialized read-only data.
