The world is full of experienced network administrators who have little or no experience configuring or managing firewalls. Firewalls 24seven, Second Edition is for them. Fully updated for the latest technologies, it starts at the highest level, drills down to specific firewall applications and scenarios, and offers systematic guidance on choosing and implementing the right firewall.
Matthew Strebe and Charles Perkins first show how "generic" firewalls work, identifying the threats and TCP/IP vulnerabilities they're intended to address, and helping you "filter out" vendor hype to identify the features you really need.
They give netadmins a thorough grounding in encryption, packet filtering, and network address translation for small networks; VPNs; and application-level proxies such as the TIS Firewall Toolkit, which serve as "middlemen" between desktop applications and Internet services.
Strebe and Perkins review today's leading firewall options, organized into several categories: free firewalls, the built-in Windows 2000 firewall; third-party Windows firewalls; UNIX firewalls; and dedicated firewalls. They also provide a detailed introduction to of Linux firewalling with ipchains, Tripwire, and other tools. And, since even the best firewall isn't always enough, they offer an up-to-date overview of the intrusion detection systems that are increasingly used in tandem with firewalls. (Bill Camarda)
