Now in its third edition, the best-selling SECURITY+ GUIDE TO NETWORK SECURITY FUNDAMENTALS provides the most up-to-date industry information, reflecting the changes in security that have occurred since the most recent CompTIA Security+ objectives were created. The book covers all of the new CompTIA Security+ 2008 exam objectives and maps to the new Security+ 2008 exam. This updated edition features many all-new topics, including topics new to the CompTIA exams like cross site scripting, SQL injection, rootkits, and virtualization, as well as topics of increasing importance in the industry as a whole, like the latest breeds of attackers, Wi-Fi Protected Access 2, and Microsoft Windows Vista security.
My exam date for the Security+ exam is coming up soon in a couple of days, and the two books which I found the most accessible and useful were the security+ book for the SY0-401 exam by Emmett Dulaney and this book. Though this particular edition is for the previous version (SY0-301),it complemented the former book incredibly well and would recommend this only as a supplement.
I took this as part of an online course through Cengage. The textbook is well structured and provides a breadth overview of Security concerns. The labs had a tendency to overly rehash the material or go completely off target from the chapter material it is included in.
