Information

This policy setting allows you to join Microsoft Active Protection Service (MAPS), which Microsoft has now renamed to 'Windows Defender Antivirus Cloud Protection Service'. Microsoft MAPS / Windows Defender Antivirus Cloud Protection Service is the online community that helps you choose how to respond to potential threats. The community also helps stop the spread of new malicious software infections. You can choose to send basic or additional information about detected software. Additional information helps Microsoft create new definitions and help it to protect your computer.

Possible options are:

(0x0) Disabled (default)

(0x1) Basic membership

(0x2) Advanced membership

Basic membership will send basic information to Microsoft about software that has been detected including where the software came from the actions that you apply or that are applied automatically and whether the actions were successful.

Advanced membership in addition to basic information will send more information to Microsoft about malicious software spyware and potentially unwanted software including the location of the software file names how the software operates and how it has impacted your computer.

The recommended state for this setting is: Disabled.




Rationale:

The information that would be sent can include things like location of detected items on your computer if harmful software was removed. The information would be automatically collected and sent. In some instances personal information might unintentionally be sent to Microsoft. However, Microsoft states that it will not use this information to identify you or contact you.

For privacy reasons in high security environments, it is best to prevent these data submissions altogether.

Solution

To establish the recommended configuration via GP, set the following UI path to Disabled:

Computer Configuration\Policies\Administrative Templates\Windows Components\Windows Defender Antivirus\MAPS\Join Microsoft MAPS

Note: This Group Policy path may not exist by default. It is provided by the Group Policy template WindowsDefender.admx/adml that is included with the Microsoft Windows 8.1 & Server 2012 R2 Administrative Templates (or newer).

Impact:

None - this is the default behavior.

Default Value:

Disabled. (Microsoft MAPS / Windows Defender Antivirus Cloud Protection Service will not be joined.)
