Subject: Working Call Recap


All,


We had a good call today and were able to resolve some of the last few issues that were holding up the release of Working Draft 04.


Summary:


1) After editorial review we noticed that the language for identifiers would not allow two organizations to write code and produce the same deterministic ID.  So we needed to tighten down the language and define what an OASIS STIX 2 deterministic ID actually is. Prior to the call I worked with Allan, Trey, Rich P, and the MISP folks on an acceptable solution. We reviewed the changes on the working call and the changes are now in section 2.9.  Please review. 


2) On the Malware Analysis object we had a property called "analysis_environment" that was a dictionary that used a three value vocabulary.  This design no longer works since we do not have the cyber observable container anymore.  So we had to make a change. The consensus on the call was to use properties on the malware analysis object itself and remove the vocabulary.  Those changes have been made in suggestion mode in section 4.11.  Please review.


3) We also accepted small changes to the following sections;


a) 2.7 Hashes
b) 3.2 Spec Version
c) 10.13 Infrastructure Type Vocabulary
d) 4.3 Course of Action os_execution_envs
e) 4.13 Observed Data
f) 4.18 Vulnerability Relationships



Action Items:


i) Please make a final in depth review of COA and provide any description text changes you feel appropriate. 

ii) Review the changes to Malware Analysis 

iii) Review the changes to the identifier 

iv) Start making your top down full review of the documents



Schedule:

On the call we said we would give the TC one more week to review the changes to Malware Analysis and the identifier.  So depending on how next week's working call goes, we might be able to release Working Draft 04 next week. 



Thanks

Bret
