SANS MGT 414 has been fully updated:
Course authors Eric Conrad and Seth Misenar have revised MGT414 to take into account the 2015 updates to the CISSP® exam and prepare students to navigate all types of questions included in the new version.
MGT414 focuses solely on the 8 domains of knowledge as determined by (ISC)2 that form a critical part of CISSP® exam. Each domain of knowledge is dissected into its critical components, and those components are then discussed in terms of their relationship with one another and with other areas of information security.
We are also working on the CISSP® Study Guide Third Edition. It is due out in November 2015. We will update the Eleventh Hour CISSP Study Guide after that.
I have received a lot of questions regarding CISSP® Study Guide version 2E (and other books that predate this update). Here's ISC2's take:
Q: Since the CISSP has changed from 10 to 8 domains, was some content deleted?
A: No. Content was not removed from the exam and/or training material, but rather refreshed and reorganized to include the most current information and best practices relevant to the global information security industry.
So all of the CISSP® Study Guide Second Edition material still applies, but new concepts have been added. See the CISSP® 2015 Candidate Information Bulletin for specific details on the testable topics. Here's Clement Dupuis' take on cccure.training.
Clement also has a fantastic guide to the changes (with links to online sources of new material).
