Description
Kernel DMA Protection to protect PCs against drive-by Direct Memory Access (DMA) attacks using PCI hot plug devices connected to Thunderbolt 3 ports. Drive-by DMA attacks can lead to disclosure of sensitive information residing on a PC, or even injection of malware that allows attackers to bypass the lock screen or control PCs remotely.

Who does this work

12 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \Software\Policies\Microsoft\Windows\Kernel DMA Protection Value Name: DeviceEnumerationPolicy Value Type: REG_DWORD Value: 0

Fix Text (F-56829r829361_fix)

Configure the policy value for Computer Configuration >> Administrative Templates >> System >> Kernel DMA Protection >> "Enumeration policy for external devices incompatible with Kernel DMA Protection" to "Enabled" with "Enumeration Policy" set to "Block All".
