Title

SLEM 5 must not have unnecessary accounts. (Cat II impact)

Discussion

Accounts providing no operational purpose provide additional opportunities for system compromise. Unnecessary accounts include user accounts for individuals not requiring access to the system and application accounts for applications not installed on the system.

Check Content

Verify all SLEM 5 accounts are assigned to an active system, application, or user account 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 Obtain the list of authorized system accounts from the information system security officer (ISSO). If the accounts on the system do not match the provided documentation, this is a finding.

Fix Text

Configure SLEM 5 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.
