A firewall and an intrusion detection systems (IDS) are two important weapons in that fight, enabling you to proactively deny access and monitor network traffic for signs of an attack.\u003cbr\u003e\u003cbr\u003e\u003ci\u003eLinux Firewalls\u003c\/i\u003e 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 authentication layer around iptables with fwknop.\u003cbr\u003e\u003cbr\u003eConcrete examples illustrate concepts such as firewall log analysis and policies, passive network authentication and authorization, exploit packet traces, Snort ruleset emulation, and more with coverage of these topics:\u003cbr\u003e–Passive network authentication and OS fingerprinting\u003cbr\u003e–iptables log analysis and policies\u003cbr\u003e–Application layer attack detection with the iptables string match extension\u003cbr\u003e–Building an iptables ruleset that emulates a Snort ruleset\u003cbr\u003e–Port knocking vs. Single Packet Authorization (SPA)\u003cbr\u003e–Tools for visualizing iptables logs\u003cbr\u003e\u003cbr\u003ePerl and C code snippets offer practical examples that will help you to maximize your deployment of Linux firewalls. If you're responsible for keeping a network secure, you'll find \u003ci\u003eLinux Firewalls\u003c\/i\u003e invaluable in your attempt to understand attacks and use iptables—along with psad and fwsnort—to detect and even prevent compromises.\u003c\/p\u003e\n                        \u003ch3\u003e\u003cstrong\u003eAbout the Author\u003c\/strong\u003e\u003c\/h3\u003e\n                        \u003cp\u003e\u003cb\u003eMichael Rash\u003c\/b\u003e is a Security Architect on the Dragon Intrusion Detection System with Enterasys Networks, Inc., and is a frequent contributor to open source projects.
