The SPL above uses the following Macros:
Note that splunk_enterprise_information_disclosure_filter is a empty macro by default. It allows the user to filter out any results (false positives) without editing the SPL.
How To Implement
The REST endpoint that exposes system information is also necessary for the proper operation of Splunk clustering and instrumentation. Whitelisting your Splunk systems will reduce false positives.
Known False Positives
