Update Service Status
This report collects data on the patch service on cardholder systems and uses the information from the antimalware solution to display a list of the systems within the PCI environment that are updating their signatures appropriately. Use this report to identify systems that have not updated their malware signatures as required.
The best antimalware software has limited effectiveness if it does not have current signatures or if it is not active in the network or on an individual's computer. The PCI DSS standard requires that the antimalware tools are current, which includes the signatures used to detect localized threats.

The data in the Update Service Status report is populated by by a lookup against the services_tracker CSV. This tracker is populated by the Endpoint – Services Tracker - Lookup Gen saved search.
Review each lookup generating search to learn more about the search schedule and time range.
