Configure Interesting Services list

For PCI DSS, some services are required to be running within the PCI environment. This might include a patch service like Windows Update service or other services that should be on the systems within the environment.

View the "Interesting Services" list and view the current list of required services.

  1. Select Configure > Content > Content Management.
  2. Click the Interesting Services lookup. The Interesting Services lookup file (interesting_services.csv) appears in the lookup editor.

Configure secure and insecure services

Many services are considered insecure and should never be run within a cardholder data environment. The Splunk App for PCI Compliance populates a list of insecure services by default, but a solution administrator or compliance manager might need to modify this list.

Modify the "Interesting Services" list.

  1. Select Configure > Content > Content Management.
  2. Click Interesting Services. The Interesting Services lookup file (interesting_services.csv) opens in the editor.
  3. Modify this list to identify secure and insecure services.
  4. Click Save when you are done.

There is no file checking or verification for this editor, so any typo might break the lookup file.
