Data Loss Prevention processes rules and templates by priority. If a rule is set to Pass, Data Loss Prevention processes the next rule in the list. If a rule is set to Block or User Justification, Data Loss Prevention blocks or accepts the user action and does not process that rule/template further.

  2. Specify a name for the rule.
  3. Configure the template settings:
