SYSTEM AND METHOD OF BLOCKING A COMPUTER ATTACK ON A MEANS OF TRANSPORTATION

Disclosed are systems and methods for detecting and blocking attacks on electronics systems of a means of transportation. A protection module intercepts messages being transmitted on the buses of the means of transportation and saves the intercepted messages, and also for each intercepted message at least one ECU of the means of transportation which is the recipient of that message. The protection module detects computer attacks on the electronics systems by applying one or more rules, which can be received from a security server, to the saved data in the log. The rules may depend on one or more indicators of compromise that include malicious messages used in a computer attack and information on at least one ECU that is a recipient of the malicious messages. The described system further blocks the computer attacks by blocking, modifying, or changing communications within the communications bus of the vehicle.
