API security is an ongoing lifecycle, not a one-time setup. Integrate security testing into your CI/CD pipelines.

• Automated Testing: Use DAST tools (like OWASP ZAP) configured with your OpenAPI specification to fuzz endpoints during the build process.
• Dependency Scanning: Automatically scan your package.json or requirements.txt using tools like Snyk or Dependabot to prevent Supply Chain attacks.
• Documentation Security: Do not publicly expose OpenAPI/Swagger UI endpoints for private APIs. Ensure documentation does not leak internal IP addresses or sensitive architectural details.
