Rule Set Prerequisites

Some rule sets have prerequisites that must be met before they can be fully configured and ready for use in your web policy.

Rule set Prerequisites
Activity Control

This rule set gives you fine-grained control over the cloud services in the Service Catalog, allowing you to select which activities you want blocked instead of blocking entire services. For example, you can select Box from the Service Catalog, then select download and upload activities for blocking, while allowing edit and post activities. Before you can configure these rules, you must add cloud services from the Service Catalog.

Prerequisites:

  • Add a cloud service from the Service Catalog

  2. Verify that Skyhigh Web Security Gateway Service can connect to your Advanced Threat Defense instance.
    Required settings:
    • User name and password that WSGS uses to authenticate and connect to Gateway ATD
    • Host name or IP address and port number of the server hosting Gateway ATD
