Configure Prohibited Traffic list

The PCI data security standards requires that systems in a cardholder data environment only include services necessary on the system. Using the Prohibited Traffic list, PCI compliance solutions administrators can define a list of prohibited services that they do not expect to see on systems within the environment.

To view the Prohibited Traffic list, do the following:

  1. Select Configure > Data Enrichment > Lists and Lookups.
  2. Click the Prohibited Traffic list. The Prohibited Traffic lookup file (prohibited_traffic.csv) appears in the lookup editor.

The first line in the file describes the fields in the file.
