Trust an application

Note: If you use role-based administration:

You must have the Policy setting - firewall right to configure a firewall policy.
You cannot edit a policy if it is applied outside your active sub-estate.

For more information, see Managing roles and sub-estates.

To trust an application on a group of computers:

Check which firewall policy is used by the group(s) of computers you want to configure.
See Check which policies a group uses.
In the Policies pane, double-click Firewall, and then double-click the policy you want to change.
On the Welcome page of the Firewall Policy wizard, click Advanced firewall policy.
Under Configurations, click Configure next to the location that you want to configure.
Click the Applications tab.
If the application is not in the list, follow the instructions in Add an application to a firewall policy to add it.
Select the application in the list, and then click Trust.

The application is added to the firewall policy and marked as Trusted.
The application's checksum is added to the list of allowed checksums.

Trusted applications are allowed full and unconditional network access, including access to the internet. For greater security, you can apply one or more application rules to specify the conditions under which the application can run.
