Electronic control system
Provided is an electronic control system configured to read a log recording an operation of a device and to detect a security event that is an event related to information security; execute a safety feature serving as a measure against a safety event that is an event related to functional safety; execute a security feature serving as a measure against the security event; store correspondence information indicating at least one of the safety feature and the security feature corresponding to the security event; and identify, based on the correspondence information, a feature corresponding to the security event to execute the identified feature, wherein the correspondence information records the event classified into at least one of the security events so as to correspond to the safety feature.
1 . An electronic control system comprising:
a gateway mounted on a vehicle, the gateway comprising:
a first computer processing unit (CPU) configured to:
collect a log, the log associated with an operation of a device and comprising a safety log and a security log,
detect a security event that is an event related to information security,
detect a safety event that is an event related to functional safety, and
a first storage device configured to execute a correspondence information table; and
an electronic control unit (ECU) comprising:
a second CPU configured to:
perform a security process serving as a measure against the security event, and
perform a safety process serving as a measure against the safety event, and
a second storage device configured to store the safety log and the security log,
wherein the electronic control system is further configured to:
correct the safety log and the security log,
store correspondence information indicating at least one of the safety process and the security process corresponding to the security event,
identify, based on the correspondence information, the security process corresponding to the security event, and
perform the identified security process,
wherein the correspondence information comprises the event classified into at least one of the security events so as to correspond to the safety process;
wherein the electronic control system is further configured to:
determine whether the safety process corresponding to the security event is stored as the correspondence information,
in response to the safety process being stored as the correspondence information, perform the safety process, and
in response to the safety process not stored being stored as the correspondence information, and the security process corresponding to the security event being stored as the correspondence information, perform the security process.
2 . The electronic control system according to claim 1 , wherein the ECU is further configured to detect the security event based on the safety event.
3 . The electronic control system according to claim 1 , wherein the ECU is further configured to:
identify, based on the correspondence information, the security process corresponding to the safety event, and
perform the identified security process.
