| Your Official Red Hat Linux Guide to Firewalls Reviewed and approved by the experts at Red Hat, this comprehensive reference guide gives you all the tools to construct firewalls on a Red Hat server that will lock out intruders and defend your network against attacks.
Red Hat Linux expert and IT professor Bill McCarty begins by giving you a solid foundation in security technology and philosophy. You’ll examine the importance of perimeter security and the central role packet-filtering firewalls play, understand the network traffic patterns associated with common Internet services, and explore ways to develop firewall policies that permit, prohibit, or restrict use. With this groundwork in place, you then discover how to cost-justify, design, implement, test, and operate packet-filtering firewalls constructed with Red Hat Linux. You’ll also gain valuable information about related topics, such as implementing bastion hosts and detecting network intrusion. This guidebook arms you with everything you need to secure your Red Hat Linux system with state-of-the-art firewalls.
