What does Requirement 6.2 specify regarding security patches?

Requirement 6.2 emphasizes the importance of timely installation of security patches, particularly those labeled as critical. It specifies that critical patches should be installed within one month of their release. This requirement is crucial for maintaining the security posture of systems and preventing vulnerabilities that could be exploited by attackers. By ensuring that critical patches are applied promptly, organizations can address known security weaknesses and reduce the risk of security incidents.

The focus on critical patches highlights their significance in the overall security strategy, as they often address serious vulnerabilities that could lead to breaches, data loss, or system compromise. Delay in applying these patches can expose systems to unnecessary risks, making this requirement vital for robust security management.

In contrast, the other options do not align with the standard's intent. Installing patches quarterly may not address urgent vulnerabilities in a timely manner. Considering only optional patches undermines the necessity of addressing critical vulnerabilities. Lastly, limiting patch installations to maintenance windows could cause delays in implementing essential security updates, potentially increasing exposure to threats.
