DMA Protection on Surface devices
Direct Memory Access (DMA) protection is designed to mitigate potential security vulnerabilities associated with using removable SSDs or external storage devices. Newer Surface devices come with DMA Protection enabled by default. These include:
- Surface Laptop 6, Surface Laptop 5, Surface Laptop 4, Surface Laptop 3, Surface Laptop SE, Surface Laptop Studio 2, Surface Laptop Studio, and Surface Laptop Go 3.
- Surface Pro 10, Surface Pro 9, Surface Pro 9 with 5G, Surface Pro 8, Surface Pro 7+, Surface Pro 7, and Surface Pro X.
- Surface Go 4 and Surface Go 3.
To check the presence of DMA protection feature on your device, open System Information (Start > msinfo32.exe), as shown in the figure below.
If a Surface removable SSD is tampered with, the device will shut off power. The resulting reboot causes UEFI to wipe memory, to erase any residual data.
