General Purpose Operating System SRG: SRG-OS-000118-GPOS-00060 (in versions v2 r7 through v1 r4)

Title

The operating system must disable account identifiers (individuals, groups, roles, and devices) after 35 days of inactivity. (Cat II impact)

Discussion

Inactive identifiers pose a risk to systems and applications because attackers may exploit an inactive identifier and potentially obtain undetected access to the system. Owners of inactive accounts will not notice if unauthorized access to their user account has been obtained. Operating systems need to track periods of inactivity and disable application identifiers after 35 days of inactivity.
