The TNC architecture was first introduced at the RSA Conference in 2005.[4] TNC was originally a network access control standard with a goal of multi-vendor endpoint policy enforcement.[5]
In 2009 TCG announced expanded specifications which extended the specifications to systems outside of the enterprise network.[6] Additional uses for TNC which have been reported include Industrial Control System (ICS), SCADA security,[7][8] and physical security.[9]
Specifications introduced by the TNC Work Group:[10]
- TNC Architecture for Interoperability
- IF-IMC - Integrity Measurement Collector Interface
- IF-IMV - Integrity Measurement Verifier Interface[11]
- IF-TNCCS - Trusted Network Connect Client-Server Interface[12]
- IF-M - Vendor-Specific IMC/IMV Messages Interface
- IF-T - Network Authorization Transport Interface[13]
