This curriculum spans the technical and organisational complexity of a multi-phase automotive cybersecurity rollout, comparable to securing a global OEM’s connected vehicle fleet across development, compliance, and incident response functions.

Module 1: Telematics Architecture and Attack Surface Analysis

  • Selecting between embedded, integrated, and aftermarket telematics control units (TCUs) based on OEM production constraints and security lifecycle requirements.
  • Mapping communication pathways between the TCU, CAN bus, gateway module, and cloud backend to identify high-risk data egress points.
  • Implementing hardware security modules (HSMs) within TCUs to protect cryptographic key storage and enforce secure boot processes.
  • Defining trust boundaries for over-the-air (OTA) update components, including update server, signing infrastructure, and in-vehicle update agent.
  • Evaluating the risk of legacy vehicle networks (e.g., CAN) lacking native authentication when interfacing with IP-based TCUs.
  • Documenting physical access points (OBD-II, USB, Ethernet) that expose telematics systems to local exploitation and defining mitigation controls.

Module 2: Secure Communication Protocols and Cryptographic Design

  • Choosing between TLS 1.2 and TLS 1.3 for vehicle-to-cloud communications based on hardware limitations and forward secrecy requirements.
  • Implementing mutual authentication between the TCU and backend servers using certificate-based PKI, including certificate revocation mechanisms.
  • Configuring DTLS for UDP-based vehicle-to-infrastructure (V2I) communications where packet loss precludes standard TLS.
  • Managing cryptographic key rotation schedules for symmetric keys used in intra-vehicle communications, balancing security and OTA bandwidth costs.
  • Integrating IEEE 1609.2 security services for DSRC-based V2X messages, including certificate pseudonym pools and geographic revocation lists.
  • Hardening MQTT brokers used in telematics data pipelines with TLS, client authentication, and topic-level access controls.

Module 3: Over-the-Air (OTA) Update Security and Integrity

  • Designing a dual-bank firmware update system to maintain a known-good fallback image during OTA updates.
  • Implementing end-to-end signature verification for OTA packages, from signing server to TCU execution environment.
  • Enforcing secure boot chain validation after an OTA update to prevent rollback attacks to vulnerable firmware versions.
  • Segmenting OTA update traffic from diagnostic and telemetry traffic to limit exposure during transmission.
  • Establishing a hardware-rooted trust anchor for verifying update authenticity using UEFI or secure element technology.
  • Logging and monitoring failed OTA attempts as potential indicators of tampering or denial-of-service attacks.

Module 4: Intrusion Detection and Anomaly Monitoring in Vehicle Networks

  • Deploying in-vehicle intrusion detection systems (IDS) that monitor CAN bus traffic for abnormal message frequency or spoofed identifiers.
  • Configuring behavioral baselines for ECU communication patterns to detect deviations indicating malware or unauthorized access.
  • Forwarding IDS alerts to a cloud-based security operations center (SOC) using encrypted, authenticated channels with rate limiting.
  • Integrating IDS event data with SIEM platforms for correlation with backend authentication logs and threat intelligence feeds.
  • Managing false positive rates in anomaly detection by tuning thresholds based on vehicle operating modes (e.g., ignition on, charging, idle).
  • Preserving forensic logs of detected anomalies with tamper-resistant storage and time synchronization mechanisms.

Module 5: Identity and Access Management for Telematics Services

  • Implementing OAuth 2.0 flows for mobile app access to telematics APIs, including secure token storage on user devices.
  • Defining role-based access controls (RBAC) for fleet management platforms to restrict command execution by user role.
  • Enforcing multi-factor authentication for administrative access to telematics backend systems and OTA orchestration tools.
  • Managing lifecycle of vehicle identities in identity providers (IdPs), including provisioning at manufacture and deactivation at decommission.
  • Integrating vehicle identity with user accounts to enable secure remote functions like door unlock and engine start.
  • Auditing access logs for sensitive telematics endpoints to detect unauthorized or anomalous usage patterns.

Module 6: Regulatory Compliance and Security Certification Frameworks

  • Aligning telematics security controls with UNECE WP.29 R155 and R156 requirements for CSMS and software updates.
  • Conducting ISO/SAE 21434 threat analyses and risk assessments (TARA) specifically for telematics communication scenarios.
  • Maintaining audit trails of security control implementation for compliance with GDPR and CCPA regarding vehicle data processing.
  • Documenting security-by-design decisions in architecture reviews to support third-party certification audits.
  • Implementing data minimization techniques in telematics data collection to reduce regulatory exposure and storage risk.
  • Establishing a vulnerability disclosure program (VDP) for researchers reporting telematics-related security flaws.

Module 7: Supply Chain and Third-Party Risk in Telematics Ecosystems

  • Assessing security maturity of Tier 2 suppliers providing TCU firmware or cryptographic libraries through standardized questionnaires and audits.
  • Enforcing secure software development lifecycle (SDLC) requirements in contracts with telematics software vendors.
  • Validating SBOMs (Software Bill of Materials) for open-source components in TCU software to identify vulnerable dependencies.
  • Isolating third-party application containers in connected car platforms to prevent privilege escalation to critical vehicle systems.
  • Monitoring API usage patterns from third-party service providers to detect data exfiltration or abuse.
  • Requiring penetration test reports from cloud infrastructure providers hosting telematics backend services.

Module 8: Incident Response and Forensic Readiness for Connected Vehicles

  • Developing playbooks for responding to telematics-specific incidents such as mass OTA compromise or GPS spoofing attacks.
  • Preserving volatile memory and logged CAN traffic from affected vehicles for forensic analysis after a security event.
  • Coordinating disclosure timelines with legal, PR, and regulatory teams when a telematics vulnerability affects multiple vehicle models.
  • Establishing secure, encrypted channels for remote vehicle diagnostics during an active incident investigation.
  • Conducting post-incident reviews to update threat models and improve detection capabilities for future events.
  • Engaging with law enforcement and information sharing organizations (ISACs) when attacks involve coordinated fleet targeting.
