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).^[1]^[2]^[3]

History

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]

TNC Customer Adoption

The U.S. Army has planned to use this technology to enhance the security of its computer networks.^[16]

The South Carolina Department of Probation, Parole, and Pardon Services has tested a TNC-SCAP integration combination in a pilot program.^[17]
