Equip your automotive development team with a comprehensive self-assessment programme designed to strengthen cybersecurity across vehicle networks. This industry-aligned resource delivers practical insights into secure communication protocols, threat modelling, and resilience strategies critical for modern in-vehicle systems—aligned with global standards and real-world OEM and Tier-1 implementation practices.

Explore two core modules that deliver measurable impact:

  • Threat Modelling for In-Vehicle Networks: Develop robust threat models tailored to complex E/E architectures. Learn to apply data flow and attack tree methodologies based on system complexity and collaboration requirements. Define trust boundaries across domain controllers—such as ADAS and infotainment—when sharing CAN FD or Ethernet networks. Apply STRIDE analysis to evaluate attacker capabilities, including physical access and remote attack vectors, ensuring accurate risk prioritisation. Integrate threat model updates into variant management and align them with vehicle lifecycle phases to maintain security from manufacturing through to end-of-life. Deliver actionable mitigation plans for high-severity threats—like sensor spoofing—in formats that support both development teams and functional safety compliance.
  • Secure Communication Protocols: Optimise security across constrained automotive networks by selecting appropriate mechanisms such as MAC-based authentication (e.g., SecOC) or lightweight encryption. Configure IEEE 802.1AE (MACsec) on Ethernet backbones to balance security and latency in time-critical domains. Implement secure ECU-to-ECU session establishment using efficient TLS variants like TLS-PSK where full PKI is impractical. Streamline key management by mapping communication matrices to cryptographic groups, reducing operational complexity across vehicle fleets.

Designed for engineering leads, cybersecurity architects, and systems engineers, this self-assessment enables organisations to identify capability gaps, strengthen compliance posture, and future-proof vehicle designs against evolving cyber threats.

Elevate your cybersecurity maturity—start the assessment today and build confidence in your vehicle security framework.
