Vulnerability discussion

The SSH daemon must be configured for IP filtering to provide a layered defense against connection attempts from unauthorized addresses.

Check content

Check the TCP wrappers configuration files to determine if sshd is configured to use TCP wrappers. # cat /etc/hosts.deny | grep -i sshd # cat /etc/hosts.allow| grep -i sshd If no entries are returned, the TCP wrappers are not configured for sshd, this is a finding.

Fix text

Add appropriate IP restrictions for SSH to the /etc/hosts.deny and/or /etc/hosts.allow files.

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.
