What is a security control assessment?

• A. Evaluation of how effectively controls mitigate risk; may include testing, reviews, and gap analysis.
• B. Auditing user passwords.
• C. Installing antivirus software.
• D. Designing network diagrams.

Answer: (C)

A security control assessment is about evaluating how well safeguards reduce risk in practice. It goes beyond just having controls in place and asks whether they actually work the way they’re supposed to. This typically includes testing the controls to verify their effectiveness, reviews of how they’re designed and implemented, and gap analysis to identify weaknesses or areas where residual risk remains. Think of it as a performance check: you’re measuring how well the controls mitigate threat scenarios, not just whether a control exists. For example, auditing passwords or installing antivirus are actions related to security, but they’re specific tasks. A full assessment, by contrast, looks at the overall set of controls and determines if they collectively reduce risk to acceptable levels. Designing network diagrams is part of planning or documentation, not an assessment of control effectiveness.
