SV-26976r2_rule The system's local firewall must implement a deny-all, allow-by-exception policy.

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

If the system is not a global zone, this vulnerability is not applicable. Check the firewall rules for a default deny rule. # ipfstat -i An example of a default deny rule is: block in log quick on ne3 from any to any. If there is no default deny rule, this is a finding.

Fix text

Edit /etc/ipf/ipf.conf and add a default deny rule. Restart the ipfilter service. # svcadm restart network/ipfilter

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.
