This policy setting allows you to specify a list of Plug and Play hardware IDs and compatible IDs for devices that Windows is prevented from installing. This policy setting takes precedence over any other policy setting that allows Windows to install a device. If you enable this policy setting, Windows is prevented from installing a device whose hardware ID or compatible ID appears in the list you create. If you enable this policy setting on a remote desktop server, the policy setting affects redirection of the specified devices from a remote desktop client to the remote desktop server. If you disable or do not configure this policy setting, devices can be installed and updated as allowed or prevented by other policy settings. The recommended state for this setting is: True (checked). Note: In versions of Windows 10 Release 1803 (and newer), there is a new control named Enumeration policy for external devices incompatible with Kernel DMA Protection available that mitigates much of the risk for malicious devices that may perform Direct Memory Access (DMA) attacks. The newer control is also now part of the Windows 10 CIS benchmark, in section 18.8.26. However, if your environment still contains any Windows 10 Release 1709 (or older) workstations, then the newer control will not work, so this setting remains important to disable Thunderbolt devices on those systems. Rationale: A BitLocker-protected computer may be vulnerable to Direct Memory Access (DMA) attacks when the computer is turned on or is in the Standby power state - this includes when the workstation is locked. BitLocker with TPM-only authentication lets a computer enter the power-on state without any pre-boot authentication. Therefore, an attacker may be able to perform DMA attacks. This issue is documented in Microsoft Knowledge Base article 2516445: Blocking the SBP-2 driver and Thunderbolt controllers to reduce 1394 DMA and Thunderbolt DMA threats to BitLocker. Impact: Existing devices (that match the device IDs specified) that were previously installed prior to the hardening will be disabled or removed.
To establish the recommended configuration, set the following Device Configuration Policy to Enabled, and check the Also apply to matching devices that are already installed. checkbox: 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 (Administrative Templates) Click Create Enter a Name Click Next Configure the following Setting Path: Computer Configuration/System/Device Installation/Device Installation Restrictions Setting Name: Prevent installation of devices that match any of these device IDs Configuration: Also apply to matching devices that are already installed. (checked) 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 recommendation can also be set using the Endpoint protection profile using Windows Encryption settings. Default Value: False (unchecked). (Pre-existing devices matching the device IDs will not be disabled or removed.)
