OWASP ZAP (Zed Attack Proxy) is an open-source web application security scanner. It is designed to find security vulnerabilities in web applications. ZAP is both flexible and extensible, making it suitable for both beginners and professionals in web application security.

• Automated Scanning: Automatically scans web applications for vulnerabilities.
• Manual Testing: Provides tools for manual security testing.
• API Integration: Can be integrated into CI/CD pipelines for automated security testing.
• Extensibility: Supports plugins to extend its functionality.

• Free and Open Source: No cost involved, with a large community for support.
• Comprehensive: Covers a wide range of security vulnerabilities.
• User-Friendly: Suitable for both beginners and advanced users.
• Regular Updates: Continuously updated with new features and vulnerability checks.

1. Download ZAP: Visit the official ZAP website and download the appropriate version for your operating system.
2. Install ZAP:
   • Windows: Run the installer and follow the on-screen instructions.
   • MacOS: Open the downloaded DMG file and drag ZAP to the Applications folder.
   • Linux: Extract the downloaded tar.gz file and run the zap.sh script.

1. Start ZAP: Launch the ZAP application.
2. Set Up Proxy: Configure your browser to use ZAP as a proxy. Typically, this involves setting the proxy server to localhost and the port to 8080.
3. API Key: Generate an API key if you plan to use ZAP's API for automation.

• Session Management: Save your sessions to keep track of your scans and results.
• Context Configuration: Define contexts to group related URLs and apply specific rules.
• Authentication: Configure authentication if your application requires login credentials.

• Active Scan: Actively probes the web application for vulnerabilities. This can be intrusive and may affect the application.
• Passive Scan: Monitors the traffic between the browser and the web application without actively probing for vulnerabilities.

1. Spidering: Use the spider tool to discover all the URLs in the web application.
2. Active Scan: Run an active scan on the discovered URLs to identify vulnerabilities.
3. Review Results: Analyze the scan results to identify and prioritize vulnerabilities.

• Spidering: The script first spiders the target URL to discover all the links.
• Active Scan: It then runs an active scan on the discovered URLs.
• Results: Finally, it retrieves and prints the scan results.

1. Set Up ZAP in CI/CD: Install ZAP on your CI/CD server.
2. API Usage: Use ZAP's API to automate scans as part of your CI/CD pipeline.
3. Reporting: Generate and analyze reports to ensure security checks are part of your deployment process.

• Install ZAP: Install ZAP on the Jenkins server.
• Jenkins Job: Create a Jenkins job that runs a ZAP scan using a script similar to the one above.
• Post-Build Actions: Add post-build actions to analyze the scan results and fail the build if critical vulnerabilities are found.

In this section, we covered the basics of OWASP ZAP, including its installation, configuration, and usage for vulnerability scanning. We also explored how to automate security tests using ZAP's API and integrate it into CI/CD pipelines. By mastering these concepts, you can effectively use ZAP to enhance the security of your web applications.
