Computer systems in modern vehicles are very complex, they contain a huge quantity of devices and units that exchange a lot of data in real-time.
These components communicate via the vehicle’s network, dubbed Controller Area Network (CAN). Modern cars have multiple CAN buses combined with a gateway.
These components run software that could be potentially affected by security
Cisco has released a new hardware open-source tool called 4CAN that aims to help the automotive industry in security vehicles.
Researchers could use 4CAN to test their on-board computers for potential security flaws, according to the company it is very easy to use. Vehicles analyzed by Cisco’s researchers have 4 CAN buses all connected to the same gateway.
“A typical vehicle setup has multiple CAN buses combined with a gateway to arbitrate access between the CAN
Cisco explained that 4CAN has been designed to achieve the following goals:
The 4CAN project is loosely based on the IndustrialBerry QUAD CAN BUS adapter for Raspberry CanBerry.
“Using 4CAN, the test bench setup is vastly simplified. With a single Raspberry Pi, we can simultaneously test four CAN channels, and since the 4CAN exposes the entire 40-pin GPIO header, we can remotely control the test vehicle,” Cisco continues.
