Episode 20 — Validate access control effectiveness with reviews, testing, and corrective action
This episode teaches how to validate access controls so you can detect gaps before attackers or auditors do, a theme that shows up frequently in control-focused exams. You’ll learn what “effective” means: access matches job needs, sensitive resources are protected, privileges are limited, and changes are reviewed and corrected on a schedule. We’ll cover access reviews, including frequency, scoping high-risk groups and resources, and validating that approvals are meaningful rather than rubber-stamped. You’ll also discuss testing approaches, such as attempting least-privilege verification, checking for privilege escalation paths, and confirming that revoked access truly stops working across sessions, tokens, and cached credentials. Real-world scenarios include cleaning up inherited permissions after reorganizations and validating that terminated users cannot access SaaS apps via lingering SSO sessions. Troubleshooting focuses on review fatigue, incomplete evidence, and corrective actions that never close, with guidance on tying findings to owners, deadlines, and proof of remediation so validation becomes a continuous improvement loop.
