Network Security Principles and Practices

Very clear explanations of the core security technologies. The author doesn't shy away from the hard subjects, and makes them quite accessible. The IPSec chapter is the best explanation of the subject I have seen anywhere. I used this book to pass the CCIE security written exam, and highly recommend it. It is also a very good reference for practicing consultants and network security architects.

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.

Not only for exam preparation, this book is for every Cisco lover. Covers a lot of stuff, took me over 2 months to finish but I feel way more knowledgeable now.

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!

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. JeremyCCIE (R/S, Security
