#### To configure security for the Admin Service's JMX connector

The Admin Service determines whether the server instance is a regular instance, a domain administration server (DAS), or a combination. Platform Edition has only one server instance, and it is a combination. Use the Admin Service to configure a JSR-160 compliant remote JMX connector, which handles communication between the domain administration server and the node agents, which manage server instances on a host machine, for remote server instances.

1. Expand the Configurations node.

2. Select the instance to configure:

   - To configure a particular instance, expand the instance's config node. For example, the default instance, `server`, expand the `server-config` node.

   - To configure the default settings for all instances, expand the `default-config` node.

3. Expand the Admin Service node.

4. Select the admin service to be modified.

5. Follow the procedure in To set listener security properties to set security properties.

6. Click Save to save the changes, or click Load Defaults to restore the properties to their default values.
