Configure Interesting Services list

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

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

1. Select Configure > Data Enrichment > Lists and Lookups.
2. Click the Interesting Services list. The Interesting Services lookup file (interesting_services.csv) appears in the lookup editor.

Configure secure and insecure services

Many services are considered insecure (for example, Telnet) 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.
