Meet mandatory requirements for CAN bus cyber security

CAN bus (CAN) is the primary networking technology used in vehicles for safety-critical systems. But CAN technology has well-known security shortcomings. For vehicle homologation today, manufacturers and suppliers need CAN bus cyber security capabilities in vehicle networks to meet industry standards and regulation and make sure that the CAN bus traffic is cyber-secure.
