Why is patch management important, and what is a typical patch cycle?

• A. A cycle that includes vendor negotiations.
• B. Patches fix security vulnerabilities; cycle includes inventory, assessment, testing, deployment, and verification.
• C. A cycle focused only on deployment.
• D. A cycle that excludes verification.

Answer: (D)

Patch management reduces risk by addressing known vulnerabilities through updates. A typical patch cycle starts with inventory to identify what hardware and software exist and need updates, then assessment to determine urgency and potential impact, followed by testing to ensure patches don’t disrupt critical systems, then deployment to apply the patches, and finally verification to confirm that patches are installed correctly and systems are functioning as expected. This sequence matters because you can’t rely on deployment alone—you must know what needs patching, ensure compatibility, confirm successful installation, and verify ongoing security. Vendor negotiations aren’t part of the cycle, focusing only on deployment misses planning and risk checks, and a cycle that excludes verification would leave you unsure whether patches actually took effect or if issues were introduced.
