QA testing secure access to applications is not optional. Every authentication flow, every role-based check, every token exchange must be verified before code reaches production. Attackers look for weak links in the chain. QA exists to make sure they find none.
Secure access testing starts with authentication. Verify login forms against expected input and reject malformed requests. Test multi-factor authentication with valid, invalid, and expired codes. Check that password reset flows cannot be abused. Automate these tests and run them on every build.
Next is authorization. Confirm that users can only reach the resources allowed to them. Test direct object references, hidden endpoints, and API calls with spoofed roles. Use both automated scans and manual tests to catch edge cases.
Session management is critical. Test that sessions expire after inactivity. Confirm token revocation works. Ensure cookies are flagged with HttpOnly and Secure attributes. Simulate hijacked sessions and make sure they are destroyed.
