-== Configure cross-cluster search privilege warnings
-
-Each time a detection rule runs using a remote cross-cluster search (CCS) index pattern, it will return a warning saying that the rule may not have the required `read` privileges to the remote index. Because privileges cannot be checked across remote indices, this warning displays even when the rule actually does have `read` privileges to the remote index.
-
-If you've ensured that your detection rules have the required privileges across your remote indices, you can use the `securitySolution:enableCcsWarning` setting to disable this warning and reduce noise.
