Security Regression Testing
Security regression testing is the process of re-running security tests after code changes, patches, configuration updates, or infrastructure modifications to confirm that previously fixed vulnerabilities have not reappeared and that existing security controls still work as expected. It is a subset of regression testing focused specifically on authentication, authorization, input validation, encryption, session management, and other security-related behaviors.
