# TNC IF-T: Binding to TLS

Specification

Part of the TNC architecture is IF-T, a standard protocol used to Transport the TNC assessment exchanges leveraging the existing network connectivity. Because TNC enables assessment to occur during the process of joining a network and after the endpoint has been placed on the network, several bindings of IF-T will exist to address these different scenarios.

This document defines and specifies the IF-T protocol used when the endpoint is already on the network (has an IP address) and thus able to make use of higher layer protocols such as Transport Layer Security (TLS) to carry the assessment. Readers interested in the use of IF-T prior to joining the network (e.g. carrying EAP message over 802.1X) should refer to the TNC IF-T: Bindings for Tunneled EAP Method specification.
