Managing Application Protection Policies

Scenario

Application protection policies can be added, edited, and deleted in the following scenarios:

• Addition: HSS provides a default policy, which contains all the detection rules for application protection. If you need to customize the policy for a server, you can add a protection policy and customize the detection rules and configurations in the policy.
• Editing: You can edit a custom protection policy.
• Deletion: You can delete a custom protection policy that is not associated with any server.

2. Click in the upper left corner of the page, select a region, and choose Security > Host Security Service. The HSS page is displayed.
3. Choose PreventionApplication Protection and click Protection Policies. For more information, see Table 1.
   

   If your servers are managed by enterprise projects, you can select an enterprise project to view or operate the asset and scan information.
