For MS(GRCF)-CMDB, integration Rule engine to implement Organization sepcific rules.

While fetching the GRCF data from CMDB using integration, a Rule engine can be implement  that will help us in configuring the Organization specific rules around assets(CIA values or other attributes).

For ex: Bank ABC have a requirement that all device from IP range "XXXX" to "YYYY" should have Confidentiality value high. because they contains customer's personal data.

So there should be a rule engine where we can apply these setting(on basis of common attributes) so that we don't have to change these values manually every time data is pulled up from CMDB.
