System administrators need to stay ahead of new security vulnerabilities
that leave their networks exposed every day. 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. 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 authentication layer around iptables with fwknop.
Concrete 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:
- Passive network authentication and OS fingerprinting
- iptables log analysis and policies
- Application layer attack detection with the iptables string match
extension
- Building an iptables ruleset that emulates a Snort ruleset
- Port knocking vs. Single Packet Authorization (SPA)
- Tools for visualizing iptables logs Perl 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 Linux Firewalls invaluable in your attempt to understand
attacks and use iptables-along with psad and fwsnort-to detect and even
prevent compromises.
