From Barnes & NobleCisco PIX firewalls offer industrial-strength network security, but -- like most powerful firewalls -- they’re a challenge to configure and manage. And, since they use their own operating system and commands, there’s even more to learn. Cisco PIX Firewalls demystifies firewalls in general, then walks you through every key task, from basic traffic filtering to sophisticated IPSec configuration.
Richard Deal has written a PIX book that’s equally useful whether you’re running a PIX 501 in your home office or supporting thousands of connections with your PIX 525. How can that be possible? Well, Cisco helped, by giving all its PIXes the same operating system (and typically, the same browser-based management tool).
Second, home office and business folk are both likely to need changes in the PIX’s standard filtering. For example, if you view streaming media content, you may have to accommodate RTSP; if you use videoconferencing at work, you’ll need to handle H.323. Deal explains how to change any type of filtering, and presents specific adjustments for the most common business and home issues.
Deal presents simple explanations of outbound filtering and access lists, configuring Java and ActiveX filters for web traffic, using the basic intrusion detection built into most PIXes, password recovery, upgrades, and more. Low-end users will appreciate his coverage of NAT and DHCP -- and if you’re unfortunate enough to be saddled with PPPoE, that’s discussed, too. High-end users will appreciate his discussions of centralizing security and setting up PIX failover. Everyone will appreciate his clarity and experience. (Bill Camarda)
