Abstract

Systems and methods for a multi-sharing security firewall (200) are provided. Embodiments of a memory security firewall apparatus are provided that include region configuration logic (264), region selection logic (266), and access validation logic (268). The region configuration logic is operable to define memory protection regions of a target memory (118, 120, 146, 148), each memory protection region having two initiator groups and two sets of access attribute combinations, one for each initiator group. The region selection logic is operable to select a memory protection region that includes the address of a target memory access request from a system initiator (e.g., 122, 138). The access validation logic is operable to allow the requested memory access if the system initiator is in one of the initiator groups of the memory protection region selected by the region selection logic, and the combination of access attributes is in a set of access attribute combinations of the memory protection region.
