Managing Network Security
1 Select the "New" button to create a new policy within the Policy Manager.
2 Define the new policy based on network resources (groups, devices), users (hosts or groups of
hosts), and the predefined list of network resource services (protocols, allowed or denied).
3 Save your new policy.
4 Click the "Order" button to set the order of precedence for your policies. This must match the order
you determined while designing your access lists.
5 Verify your policies match your access list requirements using the ACL Viewer option in the Policy
Manager.
