Send data from sensors to specific receivers and searchnodes

[brazorfajeje]

I am considering for a securityonion installation on multiple geographic zones, and I would like the data in each geographic zone to be resident in the region (e.g. US data in US and EU data in EU).
The idea is obviously a distributed architecture with receiver and searchnode residing in the different geographic areas. I was wondering if there was any way to define:

• To which receivers the sensor can send data (can I define a subset of the receivers? or maybe just block the connections from firewall?)
• To which searchnodes the specific receivers can send data
  and then prevent elastic from rebalancing and sending data to searchnodes in different geographic areas, but only to those specified.

Thanks in advance
