Security evaluations provide assurance that systems meet defined security requirements. In this episode, we examine key evaluation frameworks including Common Criteria (CC), the NIST Risk Management Framework (RMF), and the ISO/IEC 27000 series. You'll learn how these models define evaluation assurance levels, categorize controls, and guide secure system development. We also discuss how evaluation results support procurement, risk analysis, and compliance audits. For CISSP candidates and practitioners, understanding security evaluation frameworks is essential for aligning technical design with governance expectations.
