Description

Our understanding is that the RFC for EAP-TLS requires mutual authentication, so we propose modifying the Module to mandate the relevant mutual authentication SFRs.

For the interface between the TOE and the NAS, is there a standard direction that the connection will always go (e.g. does the NAS as a client initiate an EAP-TLS connection with the TOE as the server, or does the TOE as a client open a persistent EAP-TLS channel to the NAS where the NAS is the server)?

The answer to this will determine whether we need to mandate FCS_TLSS_EXT.2, FCS_TLSC_EXT.2, both, or either.

Research direction

Review the EAP-TLS RFC and the Module's relevant mutual-authentication SFRs, then resolve whether the NAS or TOE initiates the connection. Done means documenting the directionality and deciding whether FCS_TLSS_EXT.2, FCS_TLSC_EXT.2, both, or either must be mandated.
