Vulnerability discussion

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 content

To check if SSH has root logins enabled, run the following command: sudo grep ^PermitRootLogin /etc/sshd_config If there is no result, or the result is set to 'yes', this is a finding.

Fix text

In order to make sure that PermitRootLogin is disabled by sshd, run the following command: sudo sed -i.bak 's/^[\#]*PermitRootLogin.*/PermitRootLogin no/' /etc/sshd_config

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.
