Dont forget this one, which is very theory based
-> The CEH Prep Guide: The Comprehensive Guide to Certified Ethical Hacking -Ronald L. Krutz (Author), Russell Dean Vines (Author).
The cd-rom that came with it is a repeat from the questionaires from the book itself.
I personally think Exam Cram 2 - Michael Gregg is very practical and hands-on. the cd-rom that came with it contains 125 questionaires which comes with good explanation.
CEH Official Review Guide-Kimberly Graves is very summarised and it helps re-inforced your understanding on the areas to be tested (which is important). the cd-rom came with 100 bonus questionaires that quite simulate the real exam test.
But since Ec-Council came up with v6, I hope Exam Cram 2 and other materials will be updated to reflect the changes in the exam based on v6.
Btw, the v5 official books are not worth it and contains too many stuffs in it.
better get something straight to the point.
Done all 3 certs, now going for CISSP.....
