TNC IF-T Binding to TLS Version 1.0, Revision 16

IF-T is the “transport” layer protocol that is responsible for carrying the TNC’s protocol messages over the network. Because it’s the lowest TNC protocol layer, it needs to be able to operate over different network technologies so that TNC can perform assessments on different kinds of networks.

In 2006, TNC released an “IF-T Binding to Tunneled EAP Methods“ specification allowing for assessments of endpoints before having TCP/IP access.  That IF-T binding leverages EAP, which is a common technology in 802.1X and IPSec’s Internet Key Exchange (IKE) protocol.  The new IF-T Binding to TLS specification describes a method of running TNC assessment over a TLS session.  This allows endpoints already on a TCP/IP network to be assessed.
