This book was written to accomplish one goal: to teach network administrators what they need to know to understand the Internet security threat, the technologies used to prevent it, and the products that exist to help them. It's the book I wish I'd had when I couldn't find a common language between various vendors that I could use to compare firewall literature and books heavy on theory to the marketing blurbs I read on websites, or when I needed help matching a specific customer's requirements to a specific firewall product.
Welcome to the Sunbelt Personal Firewall User Guide. This guide provides in-depth information
and procedures that will not only help you to understand Sunbelt Personal Firewall, but also walk you through the steps needed to protect your computer or computer network.
In the five years since the first edition of this classic book was published, Internet use has exploded. The commercial world has rushed headlong into doing business on the Web, often without integrating sound security technologies and policies into their products and methods. The security risks--and the need to protect both business and personal data--have never been greater. We've updated Building Internet Firewalls to address these newer risks.
Firewall (construction), a barrier inside a building or vehicle, designed to limit the spread of fire, heat and structural collapse
Firewall (automobile), the part of the vehicle that separates the engine from the driver and passengers
Firewall (computing), a technological barrier designed to prevent unauthorized or unwanted communications between computer networks or hosts

Cisco Security Specialist's Guide to PIX Firewall immerses the reader in the highly complicated subject of firewall implementation, deployment, configuration, and administration. This guide will instruct the reader on the necessary information to pass the CSPFA exam including protocols, hardware, software, troubleshooting and more.
Firewalls have long provided the first line of defense in network security infrastructures. They accomplish this by comparing corporate policies about users' network access rights to the connection information surrounding each access attempt. User policies and connection information must match up, or the firewall does not grant access to network resources; this helps avert break-ins.
Chapter 7 - Quản trị bảo mật cho hệ thống (Security management system). After studying this chapter you will be able to: Understand the purpose of a network firewall and the kinds of firewall technology available on the market; understand the role of routers, switches, and other networking hardware in security; determine when VPN or RAS technology works to provide a secure network connection.

The world of IT is always evolving, but in every area there are stable, core concepts that anyone just setting out needed to know last year, needs to know this year, and will still need to know next year. The purpose of the Foundations series is to identify these concepts and present them in a way that gives you the strongest possible starting point, no matter what your endeavor.
Network Security Foundations provides essential knowledge about the principles and techniques used to protect computers and networks from hackers, viruses, and other threats.
Security of corporate networks has become big business. Many companies are willing
to provide hardware, software, consulting, design, and implementation services.The
product space is vast, offering many different levels of products that claim to provide
all manner of solutions.The problem with the current state of the security space is
that it can be a difficult sea to navigate.The vast range of companies and products as
well as the ever-growing number of consulting companies can make choosing a
network security product a grueling process.
This design guide defines the comprehensive functional components required to build a site-to-site
virtual private network (VPN) system in the context of enterprise wide area network (WAN)
connectivity. This design guide covers the design topology of dynamic multipoint VPN (DMVPN).
This guide is part of an ongoing series that addresses VPN solutions, using the latest VPN technologies
from Cisco, and based on practical design principles that have been tested to scale.
The adaptive security appliance delivers unprecedented levels of defense against threats to the network
with deeper web inspection and flow-specific analysis, improved secure connectivity via end-point
security posture validation, and voice and video over VPN support. It also provides enhanced support
for intelligent information networks through improved network integration, resiliency, and scalability.
The adaptive security appliance software combines firewall, VPN concentrator, and intrusion prevention
software functionality into one software image.
