Product Description

Expert solutions for securing network infrastructures and VPNs

• Build security into the network by defining zones, implementing secure routing protocol designs, and building safe LAN switching environments
• Understand the inner workings of the Cisco PIX Firewall and analyze in-depth Cisco PIX Firewall and Cisco IOS Firewall features and concepts
• Understand what VPNs are and how they are implemented with protocols such as GRE, L2TP, and IPSec
• Gain a packet-level understanding of the IPSec suite of protocols, its associated encryption and hashing functions, and authentication techniques
• Learn how network attacks can be categorized and how the Cisco IDS is designed and can be set upto protect against them
• Control network access by learning how AAA fits into the Cisco security model and by implementing RADIUS and TACACS+ protocols
• Provision service provider security using ACLs, NBAR, and CAR to identify and control attacks
• Identify and resolve common implementation failures by evaluating real-world troubleshooting scenarios

As organizations increase their dependence on networks for core business processes and increase access to remote sites and mobile workers via virtual private networks (VPNs), network security becomes more and more critical. In today's networked era, information is an organization's most valuable resource. Lack of customer, partner, and employee access to e-commerce and data servers can impact both revenue and productivity. Even so, most networks do not have the proper degree of security. Network Security Principles and Practices provides an in-depth understanding of the policies, products, and expertise that brings organization to this extremely complex topic and boosts your confidence in the performance and integrity of your network systems and services. Written by the CCIE engineer who wrote the CCIE Security lab exam and who helped develop the CCIE Security written exam, Network Security Principles and Practices is the first book to help prepare candidates for the CCIE Security exams.

Network Security Principles and Practices is a comprehensive guide to network security threats and the policies and tools developed specifically to combat those threats. Taking a practical, applied approach to building security into networks, the book shows you how to build secure network architectures from the ground up. Security aspects of routing protocols, Layer 2 threats, and switch security features are all analyzed. A comprehensive treatment of VPNs and IPSec is presented in extensive packet-by-packet detail. The book takes a behind-the-scenes look at how the Cisco PIX(r) Firewall actually works, presenting many difficult-to-understand and new Cisco PIX Firewall and Cisco IOS(r) Firewall concepts. The book launches into a discussion of intrusion detection systems (IDS) by analyzing and breaking down modern-day network attacks, describing how an IDS deals with those threats in general, and elaborating on the Cisco implementation of IDS. The book also discusses AAA, RADIUS, and TACACS+ and their usage with some of the newer security implementations such as VPNs and proxy authentication. A complete section devoted to service provider techniques for enhancing customer security and providing support in the event of an attack is also included. Finally, the book concludes with a section dedicated to discussing tried-and-tested troubleshooting tools and techniques that are not only invaluable to candidates working toward their CCIE Security lab exam but also to the security network administrator running the operations of a network on a daily basis.

5.0 out of 5 stars This is the best book for the CCIE Security written and Lab, May 6, 2003

By	Double CCIE (Vista, ca United States) - See all my reviews

This book is very well written and covers everything you need to pass the Security part of your CCIE security lab. You will still need to study your routing and switching because that is 50% of the lab.

5.0 out of 5 stars To be added to your 'essentials' list of books, June 9, 2005

By	caskote (New Jersey, USA) - See all my reviews

Very, VERY good. The IPSec chapter alone is worth the book, and the AAA chapters are _great_. Saadat has been able to explain in a great technical level and very clearly subjects which you're going to find in your day to day work - if working with Cisco and security. But not only that: chapters about IPSec, RADIUS, TACACS, are of value even if you do not use Cisco gear.

Missing from the book: a better chapter on NAT, PPTP. Saadat should write the 2nd edition adding those two topics, updating the IDS section, IPSec (including NAT-T), maybe add a little something about SSL VPNs, PIX 7.0 ? The section on ISP security could also benefit from a refresher (CoPP, uRPF?)

4.5 starts because it shows it age - otherwise, 5 stars for sure.

5.0 out of 5 stars "the howto" security book to which others must aspire, March 17, 2004

By	Lloyd Charles Wittebol (UK) - See all my reviews

This is simply the best book for SecurIE's or security specialist's that I have ever read, the depth to which Mr Malik goes into and its accuracy are astounding.

It reads very well but also makes great reference material, and his explanation of IPsec and IKE has got rid of my 'numb feeling' from reading other books.

I cannot recommend this book enough!
