Description: Extensible Authentication Protocol Tunneled Transport Layer Security (EAP-TTLS) is an EAP (Extensible Authentication Protocol) method that encapsulates a Transport Layer Security (TLS) session, consisting of two phases. The first involves authenticating the server to the client or mutually authenticating them to one another using standard Transport Layer Security (TLS) procedures to create a cryptographically secure tunnel for information exchange. This second phase involves authenticating the client to the server or mutually authenticating them to one another using an arbitrary authentication mechanism encapsulated within the secure tunnel.
Technology/Standard Usage Requirements: Users must ensure their use of this technology/standard is consistent with VA policies and standards, including, but not limited to, VA Handbooks 6102 and 6500; VA Directives 6004, 6513, and 6517; and National Institute of Standards and Technology (NIST) standards, including Federal Information Processing Standards (FIPS). Users must ensure sensitive data is properly protected in compliance with all VA regulations. Prior to use of this technology, users should check with their supervisor, Information Security Officer (ISO), Facility Chief Information Officer (CIO), or local Office of Information and Technology (OI&T) representative to ensure that all actions are consistent with current VA policies and procedures prior to implementation.
