Paranoid Penguin - Linux Firewalls for Everyone

Need a personal firewall, an enterprise Internet gateway or something in between? iptables does it all!
Conclusions

A couple years ago, Linux Journal named iptables its Security Tool of the year. It really is a remarkable achievement. If you're serious about network security, you'll want to explore iptables' power in much greater detail than we've done in this article, starting with the iptables(8) man page and progressing through the how-tos available on the Netfilter home page (see Resources).

Whether you use iptables to protect your laptop or your entire enterprise network, I hope you've found this introduction useful. Be safe!

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6

Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
