Certified Ethical Hacker (CEH) Version 9 Cert Guide | Second Edition | By Pearson

As per author updates, less details provided in main function of hacking bound firewalls. I hope I will find in other authors publications. So if you need hacking in details please find another author. I am 100%firewall user while this books provides only 14 pages with many figures but not explained any practicals how to break their security with examples.

The book is excellent, however as a recent widower I had to drop this class to take care of my multiple impaired daughter. I'll continue to utilize this book self teaching myself. Thank You.
