Sybex's 24seven series is designed to provide the information needed by experienced system administrators and consultants. Each book is written by an expert or a team of experts. Firewalls
is a guide to securing a network from external threats, when connected to the Internet.
Keeping an Internet connected network secure is a complex task. You not only need to be aware of the known vulnerabilities of your system but also any potential attacks. Firewalls are tools for helping you do this, controlling access to and from your network.
With a copy of Firewalls you'll learn the basics of network operation and how a firewall is put together. It's important to understand risk and the book goes a long way to helping you understand risk management--and how it impacts a security policy. You'll also see how crackers target and penetrate systems. There's a guide to TCP/IP and the common Internet services. From this base camp, Firewalls begins to climb the mountain of Internet security. The basic technologies and security requirements that fit together to form a firewall are introduced, along with the security policies of the authors' "perfect firewall".
A large section of the book is taken up with comparative reviews of most of the main freeware and commercial firewall products currently available. This is a useful tool and gives you everything you're likely to need when deciding how to choose a firewall for your network.
Like the rest of the 24seven series, Firewalls is a very practical book and is aimed at the experienced network administrator who may be unfamiliar with Internet security. Real world examples and plenty of tips and warnings make this a welcome addition to the system administrator's bookshelf. --Simon Bisson
