Verify RHEL 10 system accounts do not have an interactive login shell with the following command: $ awk -F: '($3<1000){print $1 ":" $3 ":" $7}' /etc/passwd root:0:/bin/bash bin:1:/sbin/nologin daemon:2:/sbin/nologin adm:3:/sbin/nologin lp:4:/sbin/nologin Identify the listed system accounts that have a shell other than nologin. If any system account (other than the root account) has a login shell and it is not documented with the information system security officer (ISSO), this is a finding.

Fix Text (F-85634r1166455_fix)

Configure RHEL 10 so that all noninteractive accounts on the system do not have an interactive shell assigned to them. If the system account needs a shell assigned for mission operations, document the need with the ISSO. Run the following command to disable the interactive shell for a specific noninteractive user account: Replace <user> with the user that has a login shell. $ sudo usermod --shell /sbin/nologin <user> Do not perform the steps in this section on the root account. Doing so will cause the system to become inaccessible.
