Create a data access rule

A data access rule creates an additional layer of protection by managing access and enhancing protection for specific usages.

When creating a data access rule, you can do one of the following:

Create a draft of the rule. This action doesn't start the synchronization (sync), allowing you to work on the rule later. The sync status of a draft rule is Draft.
Publish the rule. This action starts the sync, sending the rule to the source. The sync status of a published rule is initially Pending, and it changes to Active if the sync is successful.

Prerequisites

You have a global role that has the Protect > Edit or Protect > Administration global permission.
You have the Catalog global role. This role is required to view data classifications for selection in a data access rule.
Protect groups are created.

Steps

Open Protect.
Click the Data Access Rules tab.
Click Create Data Access Rule.
