Administrator users must never log in directly as root. To assure individual accountability and prevent unauthorized access, logging in as root over a remote connection must be disabled. Administrators should only run commands as root after first authenticating with their individual user names and passwords.

Check Text ( C-33731r607245_chk )
If SSH is not being used, this is Not Applicable. To check if SSH has root logins enabled, run the following command: /usr/bin/grep ^PermitRootLogin /etc/ssh/sshd_config If there is no result, or the result is set to "yes", this is a finding.

Fix Text (F-33704r607246_fix)
To ensure that "PermitRootLogin" is disabled by sshd, run the following command: /usr/bin/sudo /usr/bin/sed -i.bak 's/^[\#]*PermitRootLogin.*/PermitRootLogin no/' /etc/ssh/sshd_config
