Testing IT systems of a vehicle for existing bugs, backdoors or weak points in the software architecture is becoming more and more complex. The reasons for this are more and more third-party applications, the increasing complexity and ever faster update cycles, which can also be executed remotely. The new Secure Communication Unit (SCU) addresses cyber-security issues in the development process of networked vehicles, regardless of any existing software or third-party systems. SCU is connected to various sub-networks or gateways in the vehicle and acts as a control unit for secure inbound and outbound data traffic. Tight security policies and separation among each other prevent unwanted contact between individual vehicle components and ensure trouble-free data communication within the vehicle network.
SCU is a software platform whose components follow the trustworthy-by-design approach. The proprietary microkernel-based operating system KasperskyOS has been developed according to proven, safety-oriented principles and is particularly suitable for use within embedded systems with strict cyber-security requirements. KasperskyOS prevents undocumented functionality from being executed, minimizing the risk of cyber attacks. Even if unauthorized code were to get into the system, it could not be executed because any undocumented functionality is not permitted by default.
