Securing Vehicular Controller Area Networks: An Approach to Active Bus-Level Countermeasures

With the increasing number of embedded processors and wireless interfaces being incorporated into modern automobiles, cybersecurity is emerging as a major concern for the automotive industry [1], [2]. Numerous remote attack surfaces and a high level of computer-controlled critical systems make security of automotive networks an increasingly complex technical challenge [3], [4]. Many researchers have demonstrated attacks that leverage a car's wireless interfaces to gain access to internal communication buses [5], [6]. With bus level access, an attacker has the ability to control or manipulate critical systems, such as the antilock brakes and cruise control, potentially affecting driver safety [7], [8].
