TNC IF-TNCCS Specification

The Trusted Network Connect Work Group (TNC-WG) has defined an open solution architecture that enables network operators to enforce policies regarding the security state of endpoints in order to determine whether to grant access to a requested network infrastructure.

This security assessment of each endpoint is performed using a set of asserted integrity measurements covering aspects of the operational environment of the endpoint. Integrity measurements are carried between the TNC Client and TNC Server on a protocol called IF-TNCCS (Trusted Network Connect Client-Server).
