4.5. Compliance, Auditing, and Vulnerability Management

Compliance turns security requirements into verifiable, auditable controls. An organization that says "we follow CIS Benchmarks" must be able to prove it — through automated scanning, audit logs, and file integrity monitoring. The XK0-006 exam tests the tools that implement this: OpenSCAP, AIDE, auditd, and secure destruction methods.

💡 First Principle: You cannot secure what you cannot measure. Compliance frameworks (CIS Benchmarks, OpenSCAP profiles) provide measurable, testable standards. File integrity monitoring detects unauthorized changes. Audit logs record who did what and when. Together, these tools answer the security question: "has anything changed that shouldn't have?"

⚠️ Common Misconception: Compliance is not security — it's a baseline. A system that passes all CIS Benchmark checks is not necessarily secure against all threats; it meets a defined minimum standard. True security requires continuous monitoring, rapid response, and threat intelligence beyond any checklist.
