Securing Netfilter connection tracking helpers

Following the presentation I’ve made during the 8th Netfilter Workshop, it was decided to write a document containing the best practices for a secure use of iptables and connection tracking helpers.

This document called “Secure use of iptables and connection tracking helpers” is now available on this site. It contains recommendations that should be followed carefully if you are the administrator of a Netfilter/Iptables or the developer of a Netfilter based software.
