The systems in a group, by default, inherit policies from their parent group. You can enforce changes to this default policy assignment on a single managed system by using policy enforcement.
Select Menu → Systems → System Tree, click Systems tab, then select the group under System Tree where the system belongs.
The list of systems belonging to this group appears in the details pane.
Select a system, then click Actions → Agent → Edit Policies on a Single System to open the Policy Assignment page.
Select a product, then click Enforcing next to Enforcement status.
Select Break inheritance and assign the policy and settings below.
Next to Enforcement status, select Enforcing or Not enforcing.
Click Save.
The policy changes are enforced to the target system.
