Episode 9 — Document Functional Control Types With Real Examples
Understanding control types helps you choose the most effective safeguard and justify it clearly. We distinguish preventive, detective, and corrective controls; physical, technical, and administrative forms; and compensating controls used when preferred options are not feasible. The episode explains how exam questions often hinge on identifying the control type needed to meet a stated objective or constraint, and how to avoid mixing categories when crafting answers. We also cover assurance language—how to phrase control statements so that scope, frequency, and responsibility are unambiguous.
We bring those definitions to life with concrete cases. For access management, a preventive control is role-based provisioning with approvals; a detective control is a weekly entitlement review; a corrective control is immediate revocation when anomalies are found. For network defense, a technical preventive control is a deny-by-default firewall rule set; a detective control is an alert for policy violations; a corrective control is an automated quarantine action. We examine how compensating controls are justified with documented risk analysis and how evidence—screenshots, logs, ticket numbers, sign-offs—proves they are equivalent or better. Troubleshooting highlights include spotting ineffective detective controls that never trigger and corrective actions without owners. By translating the taxonomy into examples and artifacts, you’ll answer classification questions with precision and design layered defenses that stand up to scrutiny.
