Title

The SUSE operating system must disable account identifiers (individuals, groups, roles, and devices) after 35 days of inactivity after password expiration. (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. The SUSE operating system needs to track periods of inactivity and disable application identifiers after 35 days of inactivity.

Check Content

Verify the SUSE operating system disables account identifiers after 35 days of inactivity since the password expiration. Check the account inactivity value by performing the following command: > sudo grep -i '^inactive' /etc/default/useradd INACTIVE=35 If no output is produced, or if "INACTIVE" is not set to a value greater than "0" and less than or equal to "35", this is a finding.

Fix Text

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.
