   • File Based
     1. Enable DLP rule match criteria for file-based based traffic.
     2. (Prisma Access 5.1 and later) Select the File Scan Mode to explicitly include or exclude specific file types.
        A DLP rule supports only one type of file mode. You can't configure a DLP rule to both include and exclude specific file types.
        • Include—Enterprise DLP only inspects the selected file types. The NGFW or Prisma Access tenant ignores all other file types and does not forward them to Enterprise DLP for inspection and verdict rendering.
        • Exclude—The NGFW or Prisma Access tenant excludes the selected file types and does not send them Enterprise DLP for inspection and verdict rendering. The NGFW or Prisma Access tenant forwards all other file types to Enterprise DLP but Enterprise DLP inspects and renders verdicts only on supported file types.
     3. Specify one or more supported file types to include in the match criteria.
        All supported file types are included in the match criteria by default.
     4. Specify the File Direction (Upload, Download, or Both).
        The default file direction is Upload. File direction support is dependent on the app. Review the list of supported apps to learn which file directions Enterprise DLP supports.

     

   • Non-File Based
     1. Enable DLP rule match criteria for non-file based traffic.
     2. Select the URL Category List Exclusions to exclude forwarding traffic from one or more specific URLs to Enterprise DLP.
        You can use a predefined URL category or create a custom URL category in the Global Configuration Scope. You can select multiple URL categories to exclude traffic from non-file inspection.
     3. Select the Application List Exclusion to exclude forwarding traffic from one or more specific apps to Enterprise DLP.
        You can use a predefined application filter or create a custom application filter in the Global Configuration Scope. You can select multiple application filters to exclude app traffic from non-file inspection.
        Enterprise DLP requires at least one Application Filter if you enable exclusions for non-file based traffic. Palo Alto Networks recommends adding the predefined DLP App Exclusion application filter if you don't have a custom or predefined application filter you want to add.

     
6. Configure the Action & Log settings.

   1. Select the Action (Alert, or Block) taken when Enterprise DLP detects sensitive data.

      The default action is Alert.
   2. Set the Log Severity when Enterprise DLP detects traffic that matches the DLP rule.

      The default severity is Low.
