A method, system, and apparatus are provided for preventing glitch attacks by using a glitch processing hardware unit (1) to deactivate a glitch filter connected between the monitored line and a reset processing unit in response to detecting a voltage glitch on a monitored line during a specified security system sequence and (2) to automatically drive a requested reaction in response to the voltage glitch by driving one of a plurality of configurable reactions comprising a device reset reaction and a process restart request, thereby preventing the voltage glitch from maliciously influencing the specified security system sequence.
