You keep hearing the term DIARMF, but the name of the new DoD 8510.01 document is simple RMF.
DoDI 8510.01 Risk Management Framework (RMF) for DoD Information Technology (IT), March 14, has been released.
So why do people keep calling it DIARMF? The draft version of DoDI 8510.01 floated around for almost 3 years and it was called DIARMF. Basically, when officials first started talking about using NIST SP 800-37 Risk Management Framework as the new DIACAP, the name DIARMF stuck.
The official name is RMF.
