Abstract
Malware infection or an abnormal operation caused by a malicious attack is detected in real time, even in an electronic device with relatively inferior processing capacity. An electronic device includes an executable code identification unit configured to receive an executable code string output from a processor, and identify at least an execution address in a user program region of an operating system (OS), and an execution address in a kernel region, and a determination unit configured to check a predetermined feature value obtained at a predetermined timing from an identification result obtained by the executable code identification unit, against a predetermined expected value, and determine that an attack happens, in a case where a difference is equal to or larger than a predetermined difference, and the determination unit notifies the processor of a predetermined abnormality notification signal if the determination unit determines that an attack happens.
