Episode 22 — Refresh Access Control Essentials and Common Pitfalls

Strong access control depends on clean identities, clear roles, and consistent enforcement, and the exam probes whether you can spot weak links. We review core principles—least privilege, need to know, separation of duties, and defense in depth—then connect them to mechanisms such as multifactor authentication, privileged access management, session timeouts, and approval workflows. You’ll learn how provisioning, entitlement reviews, and revocation timelines form a chain of evidence, why mapping permissions to business tasks prevents privilege creep, and how to distinguish authentication from authorization in stems designed to blur them. We also cover service and shared accounts, emergency access, and nonrepudiation through logging and sign-offs that demonstrate who requested, who approved, and what changed.

We devote the second half to mistakes that appear both on the exam and in daily operations. Pitfalls include adding exceptions instead of fixing roles, cloning permissions across teams without revalidation, granting standing admin rights where just-in-time elevation would suffice, and confusing encryption with access control when key management is weak. We provide quick diagnostics: look for orphaned accounts, stale groups, inconsistent naming, excessive wildcard privileges, and absent evidence of review. You’ll see how to tighten controls without breaking workflows by using pilot groups, temporary dual entitlements during transitions, and clear rollback plans. By internalizing these patterns, you will choose answers that prioritize verifiable least privilege and sustainable administration rather than cosmetic fixes that leave risk unchanged.
