CCNA Security Exam Cram (Exam IINS 640-553) Review

Average Reviews:

(More customer reviews)I purchased this book to prepare for the CCNA Security Exam due to the ratings I saw at the Amazon store. The book is pretty concise and everything is really well explained. The only dissapointing thing is the fact that there is a chapter not fully covered in the book. That is the Securing Layer 2 devices chapter. To have a full read about that topic, I would recommend the CCNA Security Official Exam Certification Guide from Cisco written by Kevin Wallace. Anyway, the Exam Cram has result in a very good book to read for preparing the exam, which I hope pass in a few weeks.
Hope you find interesting this review.

CCNA Security Official Exam Certification Guide (Exam 640-553) Review

Average Reviews:

(More customer reviews)DON'T BUY! ABSOLUTELY WORTHLESS FOR THE EXAM. This book should be billed as a primer only. It contains good introductory-level information but was nowhere near the level of depth of information required on the actual exam. The cover says it has "realistic exam questions." Not so. I passed all practice exams with ease, but on the actual exam, the level of granularity on the questions was much more in-depth than anything covered in the book. This book in no way, shape, or form prepares you for the exam. Like I said, good as an intro to the subject but definitely NOT good for exam preparation. Sorry to disappoint, but either they changed the exam to make it harder, or whoever advertised the book over-reached on their claims for how the book would prepare you. In any case, if it ever was good, it is NOT good for this exam any longer. DON'T BUY!

Implementing Cisco IOS Network Security (IINS): (CCNA Security exam 640-553) (Authorized Self-Study Guide) Review

Average Reviews:

(More customer reviews)The book is an authoritative way to learn how to configure and control various Cisco routers and switches. Perhaps most importantly from the standpoint of security, you see how routers can be used to maintain a firewall. For most companies that are connected to the Internet, a firewall is often a necessity.
Some background in understanding the basics of TCP/IP is needed. But the book explains the relevant details. If you are wondering how to configure your internal network behind a firewall, the text has common setup examples that you can copy.
There are also candid discussions about the advantages and disadvantages of various filtering methods. For example, firewalls that do packet filtering are often used. This involves maintaining a policy table with conditions for allowing or denying traffic based on parameters like source IP address, destination IP address and the port numbers. The Cisco routers that do this are very fast, because inspecting the packet headers is simple to do in silicon. But the book also explains the limitations. Notably, the analysis is stateless, so a connection that uses a multipacket handshake cannot be checked, assuming it passes the above tests. Still, packet filtering is so simple and fast that you should probably do it.
The book also delves into how to make a VPN across the Internet. A powerful and popular way to have more secure communications.
The questions at the end of each chapter are fairly straightforward. Nothing that is too complicated.
Strictly, the book is meant for those studying for a Cisco network certificate. But potentially, the scope is broader. It's a good overall explanation of routing and switching, and especially about setting up firewalls and VPNs. Not necessarily restricted to Cisco hardware. But even for the latter, the book might read better than a typical manual for a specific device.
