StackHawk is a dynamic application security testing tool that helps you find, understand, and fix security bugs in your running HTTP applications and API endpoints. It runs active security tests using OWASP top 10 best practices and can be integrated into CI/CD workflows. The scanner provides detailed scan results, including findings like SQL injection and cross-site scripting issues, and can be configured using YAML. StackHawk can be used to triage and prioritize security issues, and it can be seamlessly integrated into the development workflow.

1. Introduction to StackHawk

Short description:

StackHawk is a dynamic application security testing tool that helps you find, understand, and fix security bugs in your running HTTP applications and API endpoints. It was built for automation and CICD to be part of your robust testing strategy for your application development lifecycle.

What's up TestJS Summit? I'm Scott Gerlach, Chief Security Officer and Co-Founder here at StackHawk. Thanks for taking time to check out StackHawk and I hope you're having a great conference with TestJS Summit.

Quickly, StackHawk is a dynamic application security testing tool. You can use it to test your running HTTP applications and API endpoints for security bugs and keep them from becoming vulnerable. You can use StackHawk to run active security tests on your running REST API, GraphQL API, SOAP API, server side application and single page applications. StackHawk was built for automation and CICD to be part of your robust testing strategy for your application development lifecycle. It also makes finding, understanding and fixing security bugs easy.

2. How StackHawk Works

Short description:

StackHawk runs active security tests against your applications to ensure they handle user input and output safely. It implements OWASP top 10 best practices and can be used locally or in CI/CD workflows. The scanner is configured via YAML, providing simple descriptions and examples of security issues. Integration with CI platforms and information tools is seamless, and scan results can be sent to various channels or used for breaking builds. Running the StackHawk scanner involves using a Docker command, which performs a crawl and an attack to identify potential security issues. The results include a summary of findings, such as SQL injection and cross-site scripting issues.

How does StackHawk work you ask? Great question. StackHawk runs active security tests against your running applications to ensure that your application is handling user input and output in a safe manner as well as implementing OWASP top 10 best practices for application security. We can do this against your running application on your local host, in CI CD workflows and against applications that have yet to be published on the internet.

We also made dynamic testing fast by placing the scanner as close to the application as possible and by using open standards to inform the scanner, open API spec, GraphQL, introspection queries soap, WSDL, in addition to the scanner tuning we've made, most StackHawk customer applications scan average around or under 10 minutes.

Finding and fixing security issues is simple with StackHawk. Our focus as a company is to help developers find, and most importantly fix, security issues. The StackHawk scanner and platform are built around this simplicity model. The scanner is configured via YAML that lives with the code for the application that you're testing. When StackHawk findings are triaged, the platform is trying to give you the simplest version of the information needed to help you quickly understand what the problem is with simple descriptions and examples of patterns to help you identify the antipattern, be able to recreate the issue with tools like simple curl command to replay the attack and get you into debug mode, stepping through code as fast as possible to help you fix issues and get back to your regular job of creating value for your customers.

All of this is CI-CD enabled. Again, you can integrate this into your CI process and importantly get feedback into the CI process on scan findings. This information can be used to break a build if you choose, based on severity of untriaged findings. Most of the major CI player logos are shown here on this slide and even if your particular one isn't, chances are pretty good StackHawk will work in your platform as long as it can run a Docker container. If you can run Docker, you can run StackHawk. You can also see here StackHawk integrates with your workflow and information tools. We can notify you of your scan results in a slack channel, publish that information to Datadog or send you a simple web hook message that you can then use to process and do with the data what you choose.

Let's take a look at what running the StackHawk scanner looks like. As you can see here, I've got a standard server-side application. This one is a pulls app that I want to test for security issues. So over here on my command line, I've got a simple Docker command that I ran. So Docker run StackHawk, I fed it the StackHawk yaml, we'll look at that in a second. As you can see, it did a standard crawl, looking for all the interesting things on the web page that it could, and then it did an attack. So it actively attacked this application for potential security issues. When it was all done, we've got a summary of these findings. So I've actually got a SQL injection issue that I need to take care of. You can see that it's new. I also have a cross-site scripting issue that I've done something with before. I actually made a ticket out of this. So now it's in an assigned status. We've got a bunch of other things that we can look at as well, but let's take a look at those too.

3. Analyzing Scan Results and Configuring the Scanner

Short description:

At the bottom, there is a link to the scan. The output in a CICD system would look similar. We can jump into the scan and examine the SQL injection issue. The scan provides details on what the scanner did, the request and response, and even a curl command to reproduce the attack. The Stackhawk yaml is used to configure the scanner, specifying the application location, environment, and application ID. Additional configuration options are available for authentication, handling cookies and CSRF tokens, and excluding certain scans. If there's no time to fix the issue, it can be pushed to a Jira ticket.

Down here at the bottom, we actually have a link to this scan. So we can actually take this link and paste it into a browser. By the way, output in a CICD system would look very much like this because this is the standard output. So if you did choose to break a build, you would have this same link in CICD output.

So we can go over here to our web browser and jump right into the scan that we're looking at. We were just looking at this exact same scan. We've got the SQL injection issue that we can look at quickly. You can see that we've got a SQL injection issue. We're quickly describing what SQL injection is, how to remediate it, what it's about and what risks it might pose to an application. We also have links to different language frameworks that show you the pattern of how to prevent SQL injection in Spring, Laravel, Django and Rails, so that you can help identify the anti-pattern that we're looking for. Let's take a look at this particular issue here. We can see that on the polls SQL path, we have a post method that has some kind of an issue. Over on our right hand panel, we've got a request and response of what the scanner actually did and then came back with. We can see that the scanner made a request here against the application and it responded in some form or fashion. We can actually see that the scanner made a case when injection here, so we could replay this if we wanted to. This is all helping you understand what the scanner is trying to do and what issue it thinks it's found. But interestingly, we've got this really cool validate button up here. As I mentioned before, this validate button gives you a curl command of exactly what the scanner did to identify this particular issue. So, you can copy and replay this attack against an application.

Let's take a look at that Stackhawk yaml. Here you can see the code that I've used to build my polls application. Inside of this repository, I've also stored the Stackhawk yaml. The Stackhawk yaml is how you configure the Stackhawk scanner. So, you can see the important information that's in here is where do I find the application I need to test? In this case, it's running on my local machine, so local-host 8020. What environment am I in and what is the application ID? That is the minimal amount of information you need to run a Stackhawk scan against your application. There are other pieces of information that help tune the scanner to your application, such as authentication, how to handle cookies and CSRF tokens, as well as things you don't want the scanner to scan. If you wanted to add open API spec or GraphQL, minimal additional configuration is needed to make that happen to point the scanner at those industry standard definitions of REST API and GraphQL.

Now let's say we don't have time to fix this particular issue. We need to get this feature out for our customer, but we do want to fix it. So we can push this quickly to a Jira ticket.

4. Integrating StackHawk and Conclusion

Short description:

You can send the issue to Jira and prioritize it for future sprints or epics. Triage the issues to avoid repeated notifications. StackHawk can be integrated into your development workflow to improve software development quality. Start a free trial at stackhawk.com.

So I can send this to a Jira Cloud or Jira data center ticket right now from this particular screen. So I can push this issue straight out to Jira, and now I can prioritize that and bring it back out of the backlog when I'm ready to do it in the next sprint or in the next epic.

As you will see, this has now turned into a triaged status issue. So when we come back here to our summary of findings, you can see that our cross-site scripting has been triaged and our SQL injections have been triaged. The next time the scanner finds these things, it will remember that you have triaged them already, and it will stop trying to bring your attention to it. If you've configured builds to break, this will undo the build break mechanism and your build will continue as normal.

I hope you enjoyed my talk today and perhaps learned something new about how StackHawk can be integrated into your development workflow. If you'd like to check out StackHawk and see how you can integrate it into your development process to keep pushing the limits on software development quality, you can always start a free trial at stackhawk.com. And StackHawk is always free to use on a single application. Thanks for watching.

Designing Effective Tests With React Testing Library
Featured Workshop
React Testing Library is a great framework for React component tests because there are a lot of questions it answers for you, so you don’t need to worry about those questions. But that doesn’t mean testing is easy. There are still a lot of questions you have to figure out for yourself: How many component tests should you write vs end-to-end tests or lower-level unit tests? How can you test a certain line of code that is tricky to test? And what in the world are you supposed to do about that persistent act() warning?
In this three-hour workshop we’ll introduce React Testing Library along with a mental model for how to think about designing your component tests. This mental model will help you see how to test each bit of logic, whether or not to mock dependencies, and will help improve the design of your components. You’ll walk away with the tools, techniques, and principles you need to implement low-cost, high-value component tests.
Table of contents- The different kinds of React application tests, and where component tests fit in- A mental model for thinking about the inputs and outputs of the components you test- Options for selecting DOM elements to verify and interact with them- The value of mocks and why they shouldn’t be avoided- The challenges with asynchrony in RTL tests and how to handle them
Prerequisites- Familiarity with building applications with React- Basic experience writing automated tests with Jest or another unit testing framework- You do not need any experience with React Testing Library- Machine setup: Node LTS, Yarn
