SV-38684r1_rule The system must not permit root logins using remote access programs, such as ssh.

Vulnerability discussion

Even though communications are encrypted, an additional layer of security may be gained by extending the policy of not logging directly on as root. In addition, logging in with a user-specific account preserves the audit trail.

Check content

Determine if the SSH daemon is configured to permit root logins. Procedure: # find / -name sshd_config -ls # grep -v "^#" | grep -i permitrootlogin If the PermitRootLogin entry is not found or is not set to no, this is a finding.

Fix text

Edit the /etc/ssh/sshd_config file and set the PermitRootLogin option to no and refresh sshd. #kill -1

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.
