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 ... games:x:12:100:Games account:/var/games:/bin/bash Accounts such as "games" and "gopher" are not authorized accounts as they do not support authorized system functions.

Fix Text (F-38025r618892_fix)

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.
