PCI Asset Logging

This report provides a list of all PCI assets that have stopped logging their data to Splunk Enterprise or that have never logged data to Splunk Enterprise. Use this report to ensure that all PCI assets are logging their data to Splunk Enterprise. Use this report to repair any systems that are non-compliant in their logging configurations.

PCI DSS requires that audit logs from systems, applications, and devices in the cardholder data environment be promptly backed up to a central log server. Splunk Enterprise functions as this central log server and monitors the data flow from all PCI assets.

Relevant data sources

Relevant data sources for this report include Splunk metadata and audit logs.

How to configure this report

You do not have to configure this report. It uses Splunk metadata and the assets table to create results.

Report description

The data in the PCI Asset Logging report is populated by a lookup that runs against the assets.csv file. The user creates the asset table.
