Vulnerability discussion

Disabling directed broadcast prevents packets directed to a gateway to be broadcasted on a remote network.

Check content

Check the directed_broadcast option. # /usr/sbin/no -o directed_broadcast If the value returned is not 0, this is a finding.

Fix text

Configure directed_broadcast to 0. # /usr/sbin/no -p -o directed_broadcast=0

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.
