Verify all noninteractive SLEM 5 accounts do not have an interactive shell assigned to them with the following command:
Check the system accounts on the system.
> awk -F: '($7 !~ "/sbin/nologin" && $7 !~ "/bin/false"){print $1 ":" $3 ":" $7}' /etc/passwd
root:0:/bin/bash
nobody:65534:/bin/bash
Obtain the list of authorized system accounts from the information system security officer (ISSO).
If noninteractive accounts such as "games" or "nobody" are listed with an interactive shell, this is a finding.
