Linux Firewalls

Linux Firewalls, authored by Michael Rash and published by No Starch Press, covers five main topics:

• traditional packet filtering with iptables
• port scan detection
• snort rule translation
• port knocking
• log visualization

Linux Firewalls discusses the technical details of the iptables firewall and the Netfilter framework that are built into the Linux kernel and presents valuable information right from the first chapter.
