How often should patches be updated and tested?

• A. Only after a security incident.
• B. At regular intervals.
• C. Never.
• D. Only on critical servers.

Answer: (B)

Patching should be performed on a regular, scheduled basis with testing. This approach keeps defenses up to date without surprising users or causing outages. Regular updates reduce the time vulnerable systems are exposed to known weaknesses, following a predictable cycle that your IT team can plan around. Testing patches first in a staging or test environment helps catch compatibility issues with applications, configurations, drivers, or security controls, so deploying them in production doesn’t disrupt operations or introduce new problems. Relying on patches only after a security incident leaves systems exposed for longer and depends on reacting to threats rather than proactively reducing risk. Patching never is insecure in itself, but leaving systems unpatched creates easy targets. Limiting patching to critical servers misses other parts of the environment that can be exploited, undermining defense in depth. In practice, teams build a regular patch cadence, with expedited handling for critical or zero-day patches when necessary, always accompanied by testing and rollback plans.
