SV-26763r1_rule The SSH daemon must restrict login ability to specific users and/or groups.

Vulnerability discussion

Restricting SSH logins to a limited group of users, such as system administrators, prevents password-guessing and other SSH attacks from reaching system accounts and other accounts not authorized for SSH access.

Check content

Check the SSH daemon configuration for the AllowGroups setting. # grep -i AllowGroups /etc/ssh/sshd_config | grep -v '^#' If no lines are returned, this is a finding.

Fix text

Edit the SSH daemon configuration and add an AllowGroups directive.

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.
