Security Testing Integration

Automated security testing must be integrated seamlessly into the development workflow to catch XSS vulnerabilities early. Static analysis should run on every commit, providing immediate feedback about potential vulnerabilities. Configure tools to match your security standards, customizing rules to flag organization-specific anti-patterns. Integration with pull request workflows allows security checks to block merges of vulnerable code.

Dynamic testing requires more infrastructure but provides crucial verification that XSS protections work correctly. Implement automated scanners in staging environments that test after each deployment. These tests should cover both basic XSS patterns and advanced bypass techniques relevant to your application. Create custom test suites that understand your application's specific features, testing scenarios that generic scanners might miss.

Manual security testing remains essential for complex applications. Establish regular penetration testing schedules, focusing on new features and changed code. Security champions within development teams can perform lightweight security testing during feature development. Create playbooks for common testing scenarios, making it easier for non-security specialists to identify potential vulnerabilities. Document findings from all testing activities to identify patterns and improve automated detection.
