2.3.17.4 Ensure 'User Account Control: Detect application installations and prompt for elevation' is set to 'Enabled'

Information

This policy setting controls the behavior of application installation detection for the computer.

The recommended state for this setting is: Enabled.

Rationale:

Some malicious software will attempt to install itself after being given permission to run. For example, malicious software with a trusted application shell. The user may have given permission for the program to run because the program is trusted, but if they are then prompted for installation of an unknown component this provides another way of trapping the software before it can do damage

Impact:

When an application installation package is detected that requires elevation of privilege, the user is prompted to enter an administrative user name and password. If the user enters valid credentials, the operation continues with the applicable privilege.

Solution

To establish the recommended configuration, set the following Device Configuration Policy to Enabled:

To access the Device Configuration Policy from the Intune Home page:

Click Devices

Click Configuration profiles

Click Create profile

Select the platform (Windows 10 and later)

Select the profile (Endpoint protection)

Click Create

Enter a Name

Click Next

Configure the following Setting

Path: Endpoint protection/Local device security options/User account control
Setting Name: Elevated prompt for app installations
Configuration: Enabled

Select OK

Continue through the Wizard to complete the creation of the profile (profile assignments, applicability etc.)

Note: More than one configuration setting from each of the Configuration profiles (ex: Administrative Templates, Custom etc.) can be added to each Device Configuration Policy.

Note #2: This setting can also be created via a Custom Configuration Profile using the following OMA-URI:

Name: <Enter name>
Description: <Enter Description>
OMA-URI: ./Device/Vendor/MSFT/Policy/Config/LocalPoliciesSecurityOptions/UserAccountControl_DetectApplicationInstallationsAndPromptForElevation
Data type: Integer
Value: 1

Select OK

Continue through the Wizard to complete the creation of the profile (profile assignments, applicability etc.)

Default Value:

Disabled. (Default for enterprise. Application installation packages are not detected and prompted for elevation.)
