Fix Recommendation

Configure the system so all accounts on the system are assigned to an active system, application, or user account.

Remove accounts that do not support approved system activities or that allow for a normal user to perform administrative-level actions.

Document all authorized accounts on the system.

Check Contents

Verify all accounts on the system are assigned to an active system, application, or user account.

Obtain the list of authorized system accounts from the Information System Security Officer (ISSO).

Check the system accounts on the system with the following command:

# more /etc/passwd
root:x:0:0:root:/root:/bin/bash
bin:x:1:1:bin:/bin:/sbin/nologin
daemon:x:2:2:daemon:/sbin:/sbin/nologin
sync:x:5:0:sync:/sbin:/bin/sync
shutdown:x:6:0:shutdown:/sbin:/sbin/shutdown
halt:x:7:0:halt:/sbin:/sbin/halt
games:x:12:100:games:/usr/games:/sbin/nologin
gopher:x:13:30:gopher:/var/gopher:/sbin/nologin

Accounts such as "games" and "gopher" are not authorized accounts as they do not support authorized system functions.

If the accounts on the system do not match the provided documentation, or accounts that do not support an authorized system function are present, this is a finding.
