SLEM-05-411070 - SLEM 5 must disable account identifiers (individuals, groups, roles, and devices) after 35 days of inactivity after password expiration.
Information
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.SLEM 5 must track periods of inactivity and disable application identifiers after 35 days of inactivity.
Solution
Configure SLEM 5 to disable account identifiers after 35 days of inactivity after the password expiration.Run the following command to change the configuration for "useradd" to disable the account identifier after "35" days:
> sudo useradd -D -f 35
DOD recommendation is "35" days, but a lower value greater than "0" is acceptable.
