An automated method of asset discovery is used at least fortnightly. A vulnerability scanner with an up-to-date vulnerability database is used. The scanner runs at least daily for operating systems of internet-facing servers and internet-facing network devices, and at least fortnightly for operating systems of workstations, non-internet-facing servers and non-internet-facing network devices. Patches for internet-facing OS and network device vulnerabilities are applied within 48 hours when critical or working exploits exist, otherwise within two weeks. Patches for workstation, non-internet-facing server and network device OS are applied within one month of release. Operating systems that are no longer supported by vendors are replaced.
ACSC Essential Eight E8-PATCHOS-ML1 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 24 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 0 it maps to, and the evidence behind each claim, over MCP and REST.
