Security flaws with software applications are discovered daily. Vendors are constantly updating and patching their products to address newly discovered security vulnerabilities. Organizations (including any contractor to the organization) are required to promptly install security-relevant software updates (e.g., patches, service packs, and hot fixes). Flaws discovered during security assessments, continuous monitoring, incident response activities, or information system error handling must also be addressed expeditiously. The web server will be configured to check for and install security-relevant software updates from an authoritative source within an identified time period from the availability of the update. By default, this time period will be every 24 hours.
Verify the web server installs security-relevant software updates within 30 days unless the time period is directed by an authoritative source (e.g., IAVM, CTOs, DTMs, STIGs). If security-relevant software updates to the web server are not installed within 30 days, unless the time period is directed by an authoritative source, this is a finding.
Install security-relevant web server updates within 30 days unless the time period is directed by an authoritative source (e.g., IAVM, CTOs, DTMs, STIGs).
