Configure Interesting Services list

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.
