Firewalls 24seven [Paperback]

Book Description

Series: 24x7 (Sybex) | Publication Date: February 2002

Every company, large and small, needs to protect the information that resides on its networks, and firewalls represent the first line of defence. A "firewall" is a hardware or software product used to control network traffic between different parts of a network - most crucially, between a company's internal network and the Internet. A firewall inspects and approves or rejects each connection attempt made between the internal and external networks, keeping out unauthorized users, hiding the identity of internal users as they connect to the Internet, and in general providing border security for the company. This title shows the reader how to achieve 24x7 (continuous) security efficiently on their network, providing practical information that can be utilized immediately.

Firewalls is a guide to protecting an Internet-connected network from external threats--a complex task. You not only need to be aware of the known vulnerabilities of your system, you also need to remain alert to potential attacks. Firewalls are tools that help you do this by controlling access to and from your network.

This book teaches the basics of network operation and how a firewall is put together. It's important to understand risk, and the book helps explain risk management and how it impacts a security policy. You'll also see how hackers target and penetrate systems. There's a guide to TCP/IP and 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 that gives you everything you're likely to need when deciding how to choose a firewall for your network.

Firewalls is a very practical book 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, Amazon.co.uk --This text refers to an alternate Paperback edition.

This review is from: Firewalls 24seven (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

5.0 out of 5 stars One of the best for people with little security background, December 7, 2000

This review is from: Firewalls 24seven (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.

3.0 out of 5 stars facile market survey but little else, November 22, 1999

This review is from: Firewalls 24seven (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.
