SV-38683r1_rule The system must prevent the root account from directly logging in except from the system console.

Vulnerability discussion

Limiting the root account direct logins to only system consoles protects the root account from direct unauthorized access from a non-console device.

Check content

Check the remote login ability of the root account. Procedure: # lsuser -a rlogin root If the rlogin value is not false, this is a finding.

Fix text

The root account can be protected from non-console device logins by setting rlogin = false in the root: stanza of the /etc/security/user file. #chsec -f /etc/security/user -s root -a rlogin=false

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.
