Re: [cti-taxii] Question about multiple trust group support

I agree - it could work that way. But it could also work the other way. The problem is - if you specify enrollment as part of the spec, then *everyone* needs to support that*, and the other way is now not possible.

*Unless it is part of some type of auto-enroll profile that is not mandatory.

Jason,

I could see a cloud TAXII server allowing short-lived on-the-fly channels to be setup, very similar to the way cloud based chat / IRC servers work today.  I could also see the person setting up the channel specifying a group password or some sort of auth-token to control who can join it, or even specifying a list of email address that are allowed to join it (think Slack auto-enroll).  


Thanks,

Bret

RE the below:

Realizing that these two people will NEED and WANT to create their own permissions to make sure only they can see each others CTI information. This has two steps:
I would assert this is not necessarily true. If there is a TAXII server in the cloud, and I am paying for access to it as a client - I would not expect that I have administrative control over that service and that I can make my own sharing channels. Rather I would just expect them to tell me what channel or channels to use, and I would use those. Those channels might be sourcing data from other internal data structures, the idea that I can always create them for every service doesn't make sense.
