Worked Examples

Map ASVS controls to a checkout service; repair SQL injection with parameterization; block stored XSS with contextual encoding and CSP; diagnose CORS versus CSRF; and fix cross-tenant object access at the policy boundary.

Required evidence

Submit authorized reproduction, request and response evidence with secrets removed, code and configuration repair, bypass variants, deterministic regression, ASVS mapping, scope analysis, and residual risk. Raw scanner severity is not accepted without triage.

Oral defense

Demonstrate the violated invariant, explain why the repair generalizes, run a bypass attempt, and identify adjacent routes or versions included in scope.

Source backbone

Use OWASP ASVS, OWASP WSTG, OWASP Cheat Sheets, and NIST SSDF.
