script = zap.script()
script.load_script("custom_script.js")
5. Reporting
Generate detailed reports to prioritize remediation efforts.
Command Example:
zap-cli report -o report.html
Setting Up OWASP ZAP
1. Install OWASP ZAP
Download ZAP from the official website. It is available for Windows, macOS, and Linux.
Command Example (Linux):
sudo apt install zaproxy
2. Configure ZAP
Set up proxy settings to intercept and analyze web traffic.
3. Run a Basic Scan
Perform an automated scan against a target web application.
Command Example:
zap-cli quick-scan https://example.com
4. Explore Applications Manually
Use the integrated browser to interact with the target and discover hidden vulnerabilities.
5. Analyze Results
Review the scan results to identify and prioritize vulnerabilities.
Common Use Cases for OWASP ZAP
1. Baseline Security Scans
Quickly identify common vulnerabilities in web applications.
2. Development Integration
Integrate ZAP into CI/CD pipelines for continuous security testing.
3. Manual Testing Support
