This blog will teach you about GitHub DAST, its key features, setting up GitHub DAST, real-world examples, use cases, best practices, and alternatives to GitHub DAST.
Let’s get started
What is GitHub DAST?
GitHub DAST, short for Dynamic Application Security Testing, serves as a critical component of GitHub Security to enhance the security of web applications. It simulates attacks on web applications during their operational state to identify security vulnerabilities.
This approach mimics how malicious hackers attempt to breach an application, focusing on areas such as SQL injection, cross-site scripting, and insecure server configurations.
GitHub DAST aims to reveal these weaknesses. This enables developers to fix them before launching the application, helping to avoid potential cyberattacks. This can help prevent data breaches, protect brand reputation, and maintain customer trust.
Key Features of GitHub DAST
Understanding the effectiveness and utility of GitHub DAST requires delving into its key features. Here are the key features of GitHub DAST:
1. Empowerment of Developer Teams
GitHub DAST, along with other GitHub Security features like Code Scanning
, Secret Scanning, and Supply Chain Security
, empowers developer teams to secure their software and custom code across the software lifecycle. This integration embeds security tools directly into the DevOps workflow, facilitating a proactive security approach.
2. Real-World Attack Simulation
It simulates attacks similar to those carried out by malicious hackers, focusing on vulnerabilities that only appear in running applications. This approach helps identify security issues that other AppSec
tools might miss.
3. Few False Positives
Compared to other security testing methods, It generates fewer false positives, reporting only the vulnerabilities genuinely present in the application. This reduces the noise in the security reporting process, allowing teams to focus on genuine threats.
4. Application-Agnostic
Since it does not require access to the source code, it can be applied to any application. This flexibility means that one DAST tool can support all the development team’s applications, streamlining the security testing process.
5. Integration with Third-Party Tools
Developers can extend their security capabilities using GitHub Actions
by integrating third-party DAST tools. This extensibility allows for customized and automated security workflows, further enhancing the security posture of applications.

GitHub Actions allows you to automate workflows directly from your GitHub repository. Here’s how you should set up a workflow to run OWASP ZAP:
Create a Workflow File:
In your repository, navigate to the Actions tab and click New Workflow.
Choose to set up a workflow yourself or select a predefined template.
Edit the Workflow File:
Name your workflow file, e.g.,
dast.yml
.Copy and paste the following workflow configuration:
Step 5: Configure Secrets
If your DAST tool requires authentication or API keys, configure them in the GitHub repository settings:
Go to Settings -> Secrets.
Click on New Repository secret.
Add secrets (e.g.,
DAST_API_KEY
).
Step 6: Commit and Push Changes
Commit your workflow file to the repository:
Step 7: Monitor Workflow Runs
Navigate to the Actions tab in your repository.
You will see your DAST workflow running. Monitor its progress and check for any issues.
Step 8: Review the Report
Once you complete the workflow, you can access the DAST report as an artifact. You can download it and review it to identify and fix any vulnerabilities.
