SV-63149r1_rule The system must employ a local firewall.

Vulnerability discussion

A local firewall protects the system from exposing unnecessary or undocumented network services to the local enclave. If a system within the enclave is compromised, firewall protection on an individual system continues to protect it from attack.

Check content

Determine if the system is using a local firewall. # chkconfig --list iptables If the service is not "on" in the standard runlevel (ordinarily 3 or 5), this is a finding.

Fix text

Enable the system's local firewall. # 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.
