NIST announces the final release of NIST Interagency Report (NISTIR) 7904, Trusted Geolocation in the Cloud: Proof of Concept Implementation. This report describes a proof of concept implementation that was designed by NIST to address challenges with Infrastructure as a Service (IaaS) cloud computing technologies and geolocation. The publication provides sufficient details about the proof of concept implementation so that organizations can reproduce it if desired. NIST IR 7904 is intended to be a blueprint or template that can be used by the general security community to validate and implement the described proof of concept implementation.
