13 **Change Impact**

15 Non-MDM applications granted with the MDM permission cannot be installed.
16 
17 The **app-distribution-type** field in the [signing certificate](../../../application-dev/security/app-provision-structure.md) is used to determine whether an application is an MDM application.
18 * If **app-distribution-type** is **enterprise_mdm**, the application is an MDM application.
19 * If **app-distribution-type** is not **enterprise_mdm**, the application is a non-MDM application.
20 
21 The **availableType** attribute in the **definePermissions** field in the [config.jso file](https://gitee.com/openharmony/utils_system_resources/blob/master/systemres/main/config.json) is used to determine whether the MDM permission is granted.
22 * If **availableType** is **MDM**, the MDM permission is granted.
23 * If **availableType** is not **MDM**, the MDM permission is not granted.

31 To grant the permission to an application, declare the permission in the [module.json5 file](../../../application-dev/quick-start/module-structure.md#internal-structure-of-the-reqpermissions-attribute) if the application is developed based on the stage model or in the [config.json file](../../../application-dev/quick-start/module-configuration-file.md#requestpermissions) if the application is developed based on the FA model. Non-MDM applications cannot apply for the MDM permission.
