Subject: Re: [cti-stix] STIX 2.0-CORE Draft 1 8.4.​ Versioning Question


Digital Signatures is on my personal list of things I would like to see for STIX 2.1.  Once we do them, we can do things like confidence, opinions, assertions, etc. 


Thanks,

Bret

I do understand that and agree for the majority of cases.
To give a -special case- often coming as a concern/question about CTI:
What would happen if an adversary introduces fake/disinformation/counter-CTI?
Yes, one could use Confidence/Opinion/Judgment
But I'm looking for an answer to this, imho, valid concern.

Thanks
Best regards
