Netfilter's Connection Tracking System
FILTERING POLICIES BASED UNIQUELY on packet header information are obsolete. PABLO NEIRA AYUSO These days, stateful firewalls provide advanced mechanisms to let sysadmins Netfilter’s and security experts define more intelli- gent policies. This article describes the connection implementation details of the connection tracking system tracking system provided by the Netfilter project and also presents the required Pablo Neira Ayuso has an M.S. in computer science background to understand it, such as an and has worked for several companies in the IT secu- rity industry, with a focus on open source solutions. understanding of the Netfilter framework. Nowadays he is a full-time teacher and researcher at the University of Seville. This article will be the perfect complement to understanding the subsystem that [email protected] enables the stateful firewall available in any recent Linux kernel. The Netfilter Framework The Netfilter project was founded by Paul “Rusty” Russell during the 2.3.x development series. At that time the existing firewalling tool for Linux had serious drawbacks that required a full rewrite. Rusty decided to start from scratch and create the Netfilter framework, which comprises a set of hooks over the Linux network protocol stack. With the hooks, you can register kernel modules that do some kind of network packet handling at different stages. Iptables, the popular firewalling tool for Linux, is commonly confused with the Netfilter framework itself. This is because iptables chains and hooks have the same names. But iptables is just a brick on top of the Netfilter framework. Fortunately, Rusty spent considerable time writ- ing documentation [1] that comes in handy for anyone willing to understand the framework, al- though at some point you will surely feel the need to get your hands dirty and look at the code to go further. -
