How to make indicators part of a TAXII server collection?

[pottapitot]

Hi, I configured TAXII Server v1 on Cortex XSOAR. I am trying to get understand the idea of collections. I wish to create a multiple collections within XSOAR so that when a taxii client polls for the list of collections, it can see the list and select on the indicators required. How do I make the indicators/threat report that are added to XSOAR threat intel part of specific collections that I define in XSOAR TAXII Server?

Each configured collection is just a query that is run against the local threat intel data. The query uses the same syntax as the search bar on the indicators page, so you can test your queries and use the drop-down help from that page to help write and test your queries.

Generally a query based on the standard fields of the indicators (eg, type, verdict, source, etc) would be sufficient, but more advanced logic can be implemented if required by tagging indicators (either manually, or with a playbook in a job or incident) and then having the query look for those tag(s).
