SV-60975r1_rule Direct root account login must not be permitted for SSH access.

Vulnerability 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

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
