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


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).

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.
