Abstract:
Various embodiments are generally directed to an apparatus, method and other techniques for allocating a portion of the memory as system management random access memory (SMRAM) including a system management interrupt (SMI) handler for a system management mode (SMM), the SMI handler to handle SMIs for the SMM, generating a page table for the SMM, the page table comprising one or more mapped pages to map virtual addresses to physical addresses for the SMM, and setting one or more page table attributes for the page table to prevent a malicious code attack on the SMM.
