Section 6

Topic 18: Vulnerability Management and Patching

Defining flaws in code logic, understanding the Common Vulnerabilities and Exposures (CVE) index system, and tracking severity metrics.

Automating deployment updates, verifying update signatures, and scheduling operational updates.

Reviewing baseline vulnerability signatures, checking configuration error states, and reading automated system health reports.

Patching high-severity, network-facing vulnerabilities first to minimize exploitation vectors.

Deploying software updates to isolated staging systems first, verifying core feature compatibility, and documenting rollback procedures.

Knowledge Check

Why is patch testing in a staging environment critical before full deployment?

It ensures that the security patch does not conflict with existing software, crash operational services, or cause performance degradation.
