SP800-116 provides Federal agencies and non-governmental organizations with risk-based guidelines for the incremental rollout of PIV-enabled access points. The PIV Implementation Maturity Model (PIMM) defines stages in the process, which progress from casual Ad Hoc PIV verification, to secured “Controlled, Limited, Exclusion” zones where specific PIV authentication mechanisms are mandated. Unfortunately PIV-enabled authentication devices have not been in step with the SP800-116 guidelines, making the incremental deployment of PIV cards difficult and expensive. Most PIV implementations ceased all forward motion at the lowest PIMM maturity levels. The Cheetah paves the path to full PIV deployment.
