Fix Recommendation

Configure TOSS to disable account identifiers after 35 days of inactivity after the password expiration.

Run the following command to change the configuration for useradd:

$ sudo useradd -D -f 35

DOD recommendation is 35 days, but a lower value is acceptable. The value "-1" will disable this feature, and "0" will disable the account immediately after the password expires.

Check Contents

Verify the account identifiers (individuals, groups, roles, and devices) are disabled after 35 days of inactivity with the following command:

Check the account inactivity value by performing the following command:

$ sudo grep -i inactive /etc/default/useradd

INACTIVE=35

If "INACTIVE" is set to "-1", a value greater than "35", or is commented out, this is a finding.
