This next presentation is an overview of TCP/IP and network security with the Linux Netfilter (iptables) framework.

I’ve always thought that a network or firewall administrator needed a good grounding in networking basics, so this was part of a two-hour presentation that was designed to touch on TCP/IP before talking about iptables rulesets. You can download it here in the original Oo.org or PDF formats, or check it out online:

TCP/IP and Network Security with Iptables - OpenOffice.org
TCP/IP and Network Security with Iptables - PDF
TCP/IP and Network Security with Iptables - Online Version

One of the books I recommend anyone wanting to seriously broaden their networking knowledge read is Richard Stevens’ masterpiece The Protocols (TCP/IP Illustrated, Volume 1).
