Fix Recommendation

Edit the "/etc/ssh/sshd_config" file to have the following line and save the change:
PermitRootLogin no

Restart SSH daemon:
# stopsrc -s sshd
# startsrc -s sshd

Check Contents

Determine if the SSH daemon is configured to disable root logins:
# grep -iE "PermitRootLogin[[:blank:]]*no" /etc/ssh/sshd_config | grep -v \#

If the above command displays a line, the root login is disabled.

If the root login is not disabled, this is a finding.
