Abstract:
The present invention makes it possible for a built-in control device to suitably execute a security function while suppressing effects on the execution of primary functions. This security device is provided with: an attack detection unit, a security risk status determination unit, and an execution environment control unit. The attack detection unit detects a cyber attack against built-in devices controlled by a built-in control device. On the basis of the detection result, the security risk status determination unit determines a security risk status indicating the type of security threats and/or the degree of risk posed by the cyber attack. The execution environment control unit is provided in the built-in control device, and determines a security function against the cyber attack in accordance with the security risk status, and configures the environment of the built-in control device where the security function is to be executed so that the built-in control device can execute the security function.
