Document review for stix-v2.0-csprd01-part2-stix-objects.docx

Hi,
 

I have been working on CTI standards and network security for my PhD dissertation. I have reviewed stix-v2.0-csprd01-part2-stix-objects.docx document.  My comments are listed below:

 

If open vocabulary is defined for common external reference source names (CAPEC, CVE etc.), Interoperability will be increased between tools which will implement STIX 2.0

Some SDO object references in examples are not defined in document. If an example references other SDO or SRO, referenced SDO or SRO should be in example text or should be defined in the beginning of standard document. It will be make more clear to understand examples.  All referenced SDO and SRO id list can be reviewed. Only one example of this situation:

 

In example of course_of_action (page 16), “created_by_ref” SDO is not referenced in example or in document. I can not reach the definition of SDO

3-     Typo ErrorsIn example of course_of_action (page 16), for defining malware SDO property “relationship_type” must be “name”.Examples
