ACSC Essential Eight E8-PATCHOS-ML3: Patch Operating Systems (ML3)

All ML2 requirements plus: A vulnerability scanner is used at least fortnightly to identify missing patches in drivers and in firmware. Patches for drivers and firmware are applied within 48 hours of release when critical or working exploits exist, otherwise within one month. Patches for workstations, non-internet-facing servers and non-internet-facing network device operating systems are applied within 48 hours when critical or working exploits exist (rather than one month). The latest release, or the previous release, of operating systems are used. Operating systems that are no longer supported by vendors are replaced.
