Trusted Network Connect

Trusted Network Connect (TNC) is an open architecture for network access control, promulgated by the Trusted Network Connect Work Group (TNC-WG) of the Trusted Computing Group (TCG).

History

The TNC architecture was first introduced at the RSA Conference in 2005. TNC was originally a network access control standard with a goal of multi-vendor endpoint policy enforcement.

In 2009 TCG announced expanded specifications which extended the specifications to systems outside of the enterprise network. Additional uses for TNC which have been reported include Industrial Control System (ICS), SCADA security, and physical security.
