Splunk® App for PCI Compliance

Installation and Configuration Manual

PCI Command History

This report provides visibility into the commands that are run on PCI assets. Monitor this report on a daily basis to ensure that no excessively privileged commands are being run. You should investigate unexpected commands further.

When configuring privileged IDs on systems, make sure you assign individuals only the least privileges needed for the task at hand. Assigning least privileges helps prevent users without sufficient training from incorrectly or accidentally changing operational configuration or altering security settings. Least privilege can also help to minimize the amount of damage from unauthorized access to a privileged ID.
