As stated in the subject, the 8570 will be renamed and refocus to include security for industrial controls systems (ICS). This is a major change in critical infrastructure protection for many organizations and customers of the DoD.
My my source is Michael Chipley who presented this information at the 9th Annual ICS Summit that I'm currently attending this week.
Also DIACAP will be replaced by the Risk Management Framework.
