Jason,
How would you feel this relates to killchain?

This is very similar to what I have been working through
"Removing type information would reduce the IndicatorTypeVocab down to:

Compromised
Malicious
Watchlist
C2
Anonymization
Exfiltration
This was my internal list so far - thoughts?
Anomalous Activity
Malicious Activity
Command and Control *
Anonymization
Data Exfiltration
Lateral Movement
Privilege Escalation
Reconnaissance
Host/Process Compromise
Watchlist
Quantified Risk
Policy Violation **
* I prefer descriptive names other than acronyms like "C2", it makes it easier for translation purposes.
** Not sure about this one... its kind of straying outside the CTI realm.. although i do see a great value / need for it in the vocabulary.

I have created an issue for this as when I was reviewing the vocab list, it did not cover our use case.
The issue I created:
https://github.com/STIXProject/specifications/issues/35
I believe that this will help people use the Vocab better, and may reduce the need for custom vocabs.
Please comment on this issue to provide feed back.
Thanks.
I have included the text of the issue here for reference:
There is a discussion on cti-users and cti-stix about improving the IndicatorTypeVocab.
I believe that having a vocab is a useful thing. But I believe the existing vocab needs to be improved.
First off, type information, like e-mail, ip, file hash, domain, etc. should be removed. You should/must be able to get this information from the Observable that is part of the Indicator.
For one, there is no vocab to describe a malicious observiable, say network packet, stream, or other activity. Though if the e-mail type is removed from Malicious E-mail, and it just became Malicious (Observable), then we would have something.
Removing type information would reduce the IndicatorTypeVocab down to:
Compromised
Malicious
Watchlist
C2
Anonymization
Exfiltration
The first three are interesting, Compromised means that this Observable indicates that you ARE compromised. The Malicious means that you WILL be compromised by this Observable and Watchlist means that you MAY get compromised by this Observable.
Arguably, C2 should fall under Compromised, but as it probably requires further investigation to figure out the original compromised host, I'm fine leaving this as it's own separate type.

I think the first step would be to enter an issue in the tracker for this so that we can get it on the table. I also agree with an earlier statement that the issue of default vocab values has clear overlap with the interoperability SC so while we need to work internally within the STIX SC for ensuring our default vocabs have the appropriate values for STIX use cases it probably also makes sense to work at a higher level on the process by which we define and manage the various default controlled vocabs.
