Discussion

Security flaws with firmware 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 firmware updates. Flaws discovered during security assessments, continuous monitoring, incident response activities, or information system error handling must also be addressed expeditiously.

Check Content

Verify the network device has security-relevant firmware updates installed within 30 days unless the time period is directed by an authoritative source (e.g., IAVM, CTOs, DTMs, STIGs).

If the network device does not install security-relevant firmware updates within 30 days unless the time period is directed by an authoritative source, this is a finding.

Fix Text

Install security-relevant firmware updates within 30 days unless the time period is directed by an authoritative source (e.g., IAVM, CTOs, DTMs, STIGs).
