Patches, updates or other vendor mitigations for vulnerabilities in operating systems of internet-facing servers and internet-facing network devices are applied within 48 hours of release when vulnerabilities are assessed as critical by vendors or when working exploits exist. Required at Maturity Levels One, Two and Three of the Patch operating systems mitigation strategy (Appendices A, B and C); ISM control ISM-1877 in ASD's Essential Eight to ISM mapping (December 2023).
This control maps to 2 controls across 2 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
ACSC Essential Eight E8-PATCHOS-ISM-1877 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of ACSC Essential Eight your existing evidence covers. Hold FedRAMP Moderate and 18 of 176 ACSC Essential Eight controls already carry evidence.
Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 0 were rejected on the FedRAMP Moderate pair alone.
The graph holds this control, the 2 it maps to, and the evidence behind each claim, over MCP and REST.
