Vulnerability discussion

The "iptables" service provides the system's host-based firewalling capability for IPv4 and ICMP.

Check content

If the system is a cross-domain system, this is not applicable. Run the following command to determine the current status of the "iptables" service: # service iptables status If the service is not running, it should return the following: iptables: Firewall is not running. If the service is not running, this is a finding.

Fix text

The "iptables" service can be enabled with the following commands: # chkconfig iptables on # service iptables start

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.
