Michael Rash's book on Linux Firewalls and IDS/IPS

Linux Firewalls is subtitled "Attack Detection and Response with iptables, psad, and fwsnort", and focuses heavily on what is possible from an intrusion detection and prevention standpoint within the context of iptables. There are many books that discuss firewall concepts and still other books that discuss intrusion detection, but none that really focus on the combination of the two technologies. Significant coverage in Linux Firewalls is devoted to seeing how attacks appear within iptables logs (with automated analysis performed by psad), and how the string match extension is used by fwsnort to detect application layer attacks. The book has two chapters on port knocking and Single Packet Authorization, and wraps up with a set of visualizations with Gnuplot and AfterGlow of iptables log data from the Honeynet project. The book is available for a substantial discount at:
