Outlines the regulatory patch-timeframe landscape and supports the transition from rigid timelines to risk-informed vulnerability remediation.
Organizations face a conflicting landscape of patch requirements: CISA mandates a 45-day window for known exploited vulnerabilities (KEVs) on internet-facing systems, while federal agencies must remediate 'Critical' vulnerabilities in 15 days and 'High' in 30. FedRAMP imposes a 30/60/180-day schedule based on risk level, and PCI DSS requires 'Critical' patches within one month of release. However, immediate patching is often operationally non-viable due to the need for extensive testing in high-risk environments. The NIST SP 800-40 Rev. 4 framework advocates for a shift toward 'risk-based' remediation, where patching is viewed as only one form of risk response alongside acceptance, transfer, or mitigation through compensating controls.
Regulatory frameworks like PCI DSS and FedRAMP set specific brightline thresholds (e.g., 30 days) for critical remediation, which many organizations struggle to meet.
compliance failure and extended exposure to high-severity exploits due to delayed patch implementation
benchmarking a project's fix speed against these regulatory-standard 30-day windows is a reliable proxy for overall security maintenance effectiveness.
What if the vulnerability is in an end-of-life system and there won't be a patch? ... other compensating controls may be better?
Risk Guard focuses on available patches but does not evaluate or suggest compensating controls for end-of-life (EOL) or unpatchable components.
Risk Guard would be better if it suggested standard 'Compensating Controls' (e.g., network segmentation, WAF rules) for packages with unpatched critical vulnerabilities or EOL status.
