Title

Direct root account login must not be permitted for SSH access. (Cat II impact)

Discussion

The system should not allow users to log in as the root user directly, as audited actions would be non-attributable to a specific user.

Check Content

Determine if root login is disabled for the SSH service. # grep "^PermitRootLogin" /etc/ssh/sshd_config If the output of this command is not: PermitRootLogin no this is a finding.

Fix Text

The root role is required. Modify the sshd_config file # pfedit /etc/ssh/sshd_config Locate the line containing: PermitRootLogin Change it to: PermitRootLogin no Restart the SSH service. # svcadm restart svc:/network/ssh
