ABSTRACT:
A system comprises at least one non-hardened processor configured to run a plurality of mission related processes; at least one threat detector configured to detect one or more conditions which indicate the onset of a threat to the operation of the at least one non-hardened processor; and at least one hardened processor configured to elevate at least one health monitoring process of the at least one non-hardened processor from a background process to a foreground process when the at least one threat detector detects a condition indicating the onset of a threat, wherein the at least one hardened processor manages the operation of the at least one non-hardened processor based on the results of the at least one health monitoring process.
