Abstract
Embodiments of the present disclosure provide a method, computer program product, and system for monitoring a dynamic random-access memory (DRAM) device to detect and respond to a cryogenic attack. A processor receives a set of memory information about a DRAM device. The processor then determines a set of error indicators by processing the memory information using a set of decision parameters. The error indicators are then compared to an attack syndrome to determine if the DRAM is experiencing a cryogenic attack. If the DRAM is experiencing a cryogenic attack, access to the DRAM device is disabled.
