Before being assigned to endpoint computers or appliances, rule sets are assigned to policies and the policies are saved to the ePO - On-prem database.
Make sure you create rule sets (see Create a rule set) and activate them before assigning the rule sets to policies.
To activate rule sets, from the Policy Catalog page, edit the required DLP policy. On the selected policy page, go to Active Rule Sets tab and select Actions → Activate Rule Set, then click OK.
Note
On the Active Rule Sets page, you can click Apply Policy to apply the selected rule set to the policy. This is an alternate method of assigning rule sets to a selected policy.
On the DLP Policy Manager → Policy Assignment page, do one of the following:
Select Actions → Assign a Rule Set to policies. In the assignment window, select a rule set from the drop-down list and select the policies to assign it to. Click OK.
Select Actions → Assign Rule Sets to a policy. In the assignment window, select a policy from the drop-down list and select the rule sets to assign it to. Click OK.
Note
If you deselect a rule set or policy previously selected, the rule set is deleted from the policy.
Select Actions → Apply selected policies. In the assignment window, select the policies to save to the ePO - On-prem database. Click OK.
Only policies not yet saved to the database appear in the selection window. If you change a rule set assignment, or a rule in an assigned rule set, the policy appears and the revised policy is applied in place of the previous policy.
