Query: A good book BUT....

This book is an excellent source for the CISSP exam and any one interested in computer security BUT it has problems. I gave it a one star because of the way it is poorly written. The errors in the book are too numerous to count and the formatting of the book makes it hard to read. I hope the next version some one will proof read it for grammical and content errors. In one page alone I found 6 glaring grammical errors. In several cases the graphics are so messed up they are hard to follow. I believe the part on firewalls was not even check for errors.Even though this book was hard to read, I still got a lot out of it.
