Subject: Re: [cti-taxii] HTTPs
I am actually starting to migrate to the camp that we should not mandate HTTPS at all. We should get out of that level of the stack.
For all we know people have TAXII deployed on a private IPSEC network or over a point to point tunnel.

Currently the spec has changed from "TAXII must require HTTPS" to "TAXII must require HTTPS TLS 1.2 with TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 and <insert two full pages of text here>.
I very much disagree with us specifying TLS levels and ciper suites in our specification. There are many problems with this
- There will be vendors who do not have the ability to implement the prescribed suite for a variety of reasons, and if this is part of the spec we are basically saying those vendors can't implement TAXII.
- There will be consumers who will not want to implement the prescribed suite for a variety of reasons, and if this is part of the spec we are basically saying those consumers can't consume TAXII
- The minimally viable cipher suite viable today is not the same one that will be minimally viable 6 months from now, so the whole chapter is entirely pointless and actually can be counter-productive, as at that point it will be mandating an insecure baseline.
