Description

The use of PIV credentials facilitates standardization and reduces the risk of unauthorized access. PIV credentials are only used in an unclassified environment. DoD has mandated the use of the CAC to support identity management and personal authentication for systems covered under HSPD 12, as well as its use as a primary component of layered protection for national security systems. The application server must support the use of PIV credentials to access the management interface and perform management functions.
