A computer-implemented system and method for protecting a memory are provided. The system includes a memory section with privileged and non-privileged sections, a host gateway (HG) to generate a capability credential, a device controller (DC) to append the credential to data transmitted to the memory, and at least one IO device enabled to do direct memory access (DMA) transactions with the memory.
