Abstract: A risk analyzer analyzing a risk of a system including N (natural number greater than or equal to 2) elements connected includes: an inputter receiving, as inputs, a degree of safety of each N element against a threat to security, a connection relationship of the N elements, an entry point being an element serving as an entry to the system, and a defense target being an element protected in the system; an identifier identifying, among one or more paths from the entry point to the defense target, based on the degrees of safety and the connection relationship of the N elements, a target path in which a total sum of the degrees of safety of elements passed while the target path extends from the entry point to the defense target is lower than a threshold value; and an outputter outputting path information on the target path.

Abstract: An electronic control unit includes: a first determination unit which determines whether a message received is an address claim message; a second determination unit which determines, when it is determined that the message received is an address claim message, whether a device name included in the address claim message received is a predetermined device name; and a third determination unit which performs a predefined determination process, when it is determined that the device name included in the address claim message received is the predetermined device name, and determine whether the address claim message received is an unauthorized message according to a result of the predefined determination process.

Abstract: A risk analyzer analyzing risk of a system including N (natural number greater than or equal to 2) elements connected includes: an inputter receiving, as inputs, a cost of each N element for increasing a safety degree against a threat to security, a connection relationship of at least part of the N elements, an entry point being an element serving as an entry to the system, and a defense target being an element protected in the system; an identifier identifying, based on the cost of each N element and the connection relationship, a target element of one or more elements requiring a minimum total cost necessary for cutting off a target path from the entry point to the defense target by increasing a safety degree of one or more elements on the target path to a threshold value or more; and an outputter outputting element information indicating the target element.
