Cause

These messages are produced by the Audit - Investigation Collection ACLs saved search. The search looks for non-admin permissions to the investigation KV store collections.

Solution

Remove the unnecessary read or write access from the collections. If you see these messages, remove the corresponding [collections/<stanza_name>] collections from $SPLUNK_HOME/etc/apps/SplunkEnterpriseSecuritySuite/metadata/local.meta. Access to these collections by non-admin roles is not recommended. After making the changes, refresh the file cache from Splunk Web: http://<yoursplunkserver>:8000/en-us/debug/refresh?.

In a search head cluster environment, make these changes to the local.meta file on each member in the cluster, via the deployer if applicable. Then refresh the file cache from Splunk Web for each search head: http://<yoursplunkserver>:8000/en-us/debug/refresh?. Alternately, if there are more than a few members in the cluster, a rolling restart can be used instead of the debug/refresh command.
