Abstract
In a processing apparatus, a determination unit determines whether a jump destination address of a jump instruction in a process execution program being executed corresponds to a sensitive address region. When the determination unit determines that the jump destination address does not correspond to the sensitive address region, the security control unit executes control to allow the execution of the jump instruction and record a jump source address and the jump destination address of the jump instruction in jump history information as a jump execution record. When it is determined that the jump destination address corresponds to the sensitive address region, the security control unit searches for a 'suspicious record' in the jump history information. The suspicious record is a jump execution record corresponding to an “unusual jump destination address”.
