Hi Folks,
After years of following threads silently today, i signed up

I am in start of my CISSP prep and expect to take exam in next 2-3 months. For now I have following question:
I bought this ISC2 Official Guide to CISSP CBK 2nd Edition which do not have access control models in it , but if i go to CBTs and Cybex book, they have dedicated a lot of space on this topic .... does this mean that if it is not in the new edition, it's obsolete and is not going to be in the exam ?
Just wanted not to spend my energies on the topic which are obsolete.
thanks.
