SLES-15-020050 - The SUSE operating system 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.

The SUSE operating system needs to track periods of inactivity and disable application identifiers after 35 days of inactivity.

Solution

Configure the SUSE operating system to disable account identifiers after 35 days of inactivity since 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.
