Product Description

Amazon Review

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 --This text refers to an out of print or unavailable edition of this title.

This book provides an excellent introduction to firewalls and computer security. It is extremely well written and I would highly recommend it. The book covers generic firewall theory, but also uses specific real-world product examples and technologies.

I am a network administrator and I bought this book a few months ago to help me decide which Firewall to purchase. I have not read any other books on firewalls, nor am I a security expert but this book certainly increased my knowlege by a huge amount! Real life examples, an excellent refresher course in basic network protocols and an easy to read style made this one of the best purchases I have made recently. I actually enjoyed reading the damn thing so either it fully deserves the 5 stars or I am even sadder than I thought :)

Exellent book for System admins concenred about security 30 Jan 2001
By Jeremy Pullicino - Published on
Format: Paperback
This book does not only teach you about firewalls - it also teaches you the details of network security, hackers etc.. It helps you set up your own firewall from really small (DOS!) to huge networks. It has excellent case studies where the author gives accounts of his own real life experiences. It shows you how to set up and use the most popular firewalls around, and gives you excellent security tips. This book is not about theory, but it is about real life. If you are a systems admin who is concenerned about secuirty but do not know where to start from, then buy this book. NOW!. Jeremy Pullicino Malta

facile market survey but little else 23 Nov 1999
By Bruce D. Wilner - Published on
Format: Paperback
This book contains useful market-savvy information surveying the technology offered by various firewall vendors. Products are compared, screen shots are produced, pricing information is presented, and partially correct information about market posture and perception is offered. However, the book lacks any in-depth technical treatment. The authors should spend less time telling us how brilliant they are and bragging in sidebars about this client and that client. Then again, since the authors slapped the MCSE credential on the book jacket but said nothing about meaningful academic achievements, I guess I got what I paid for.

One of the best for people with little security background 7 Dec 2000
By dupaski - Published on
Format: Paperback
I'm an admin. and needed to get up to speed on firewalls fast. This is a great introductory book. Follow this up with "Building internet firewalls" by Zwicky, (make sure to get the second edition). Couple that with some work and you will know as much about firewalls as any expert.

Not what I thought it would be 23 Dec 2004
By talex - Published on
Format: Paperback
I bought this hoping to get a decent refrence on firewalls, so far I have opened it 8 or 9 times to review a topic and find that in every case there is a knock of Microsoft products or stellar talk on linux, this and the fact that the authors listed are MCSE, I thought this would be different. I am very disapointed to have spent money on this just to have this tired argument thrown at me yet again. The book may have some nice content, I have yet to find much because I get pretty disgusted when the 1st things written are always a view point on this issue, if I wanted more of this crap I can get that from a blog for free, and frankly it is growing old.

Finally a book for the administrator! 7 April 2000
By IT1 Aaron Barr - Published on
Format: Paperback
Firewalls 24seven is a well thought out and direct to the point book. No frills, packed with information that every System Adminstrator needs to know. I direct the day to day operations of a large military division of IT personnel and I've made this book required reading.
