How do you know your security testing is thorough? In this episode, we examine test coverage metrics and how they help evaluate the effectiveness and completeness of assessments. We explain different forms of coverage—such as code path coverage, requirement coverage, and risk-based coverage—and how to map test cases to threat models and control objectives. You'll also learn how to interpret results and identify coverage gaps. Effective measurement allows CISSPs to ensure that testing efforts align with business risks and produce actionable insights for continuous improvement.
