Summary:A system and method for accessing a tagged global variable in software, including: randomly generating tags for global variables in the software; tagging the global variables with the random tags; creating a pointer to each global variable with the random tags in unused bits of the pointer wherein the pointer points to the associated global variable; accessing one global variable indirectly using the tagged pointer; determining whether tag on the accessed global variable matches the tag on the accessed pointer; and indicating a fault when the tag on the accessed global variable does not match the tag on the accessed pointer.
