A firewall and an intrusion detection system (IDS) are two important weapons in that fight, enabling you to proactively deny access and monitor network traffic for signs of an attack. Linux Firewalls discusses the technical details of the iptables firewall and the Netfilter framework that are built into the Linux kernel, and it explains how they provide strong filtering, Network Address Translation (NAT), state tracking, and application layer inspection capabilities that rival many commercial tools. You’ll learn how to deploy iptables as an IDS with psad and fwsnort and how to build a strong, passive authentica- tion layer around iptables with fwknop. --------------------------
