Abstract
Embodiments of the claimed subject matter provide systems and methods for protecting data in dynamically allocated regions of memory. The method can include receiving the read request where the read request comprises a virtual address associated with a memory and determining a physical address associated with the virtual address. The further includes determining whether the physical address associated with the virtual address is read protected and determining whether the read request is from a component allowed to access read protected memory. The read protected memory was dynamically allocated on a per page basis. The method further includes in response to determining that the read request is to a read protected physical address and determining that the component is allowed to access read protected memory, sending the data from the physical address in the memory.
