-This policy is intended to provide additional security against external DMA capable devices. It allows for more control over the enumeration of external DMA capable devices incompatible with DMA Remapping/device memory isolation and sandboxing. 
+This policy is intended to provide additional security against external DMA capable devices. It allows for more control over the enumeration of external DMA capable devices incompatible with [DMA Remapping](https://docs.microsoft.com/windows-hardware/drivers/pci/enabling-dma-remapping-for-device-drivers)/device memory isolation and sandboxing. 
 
 Device memory sandboxing allows the OS to leverage the I/O Memory Management Unit (IOMMU) of a device to block unallowed I/O, or memory access, by the peripheral. In other words, the OS assigns a certain memory range to the peripheral. If the peripheral attempts to read/write to memory outside of the assigned range, the OS blocks it.
