This curriculum spans the technical and procedural rigor of a multi-phase automotive cybersecurity engagement, addressing wireless threat modeling, secure V2X design, and incident response with the depth expected in OEM-level security architecture reviews and third-party penetration testing programs.
Module 1: Threat Modeling and Risk Assessment for Automotive Wireless Systems
- Conduct STRIDE-based threat modeling on key wireless interfaces such as Bluetooth, Wi-Fi, and cellular to identify spoofing, tampering, and denial-of-service risks in vehicle ECUs.
- Define attack surfaces for over-the-air (OTA) update mechanisms, including vulnerabilities in update manifest validation and cryptographic signature verification.
- Evaluate the risk exposure of legacy ECUs that lack hardware security modules (HSMs) when integrated into modern wireless communication architectures.
- Map regulatory compliance requirements (e.g., UNECE WP.29, ISO/SAE 21434) to specific threat scenarios involving wireless entry points.
- Perform attack tree analysis on keyless entry systems to assess relay attack feasibility and determine required countermeasures like distance bounding protocols.
- Assess the impact of shared wireless stacks across multiple vehicle domains (infotainment, telematics, ADAS) on lateral movement risk during a compromise.
Module 2: Secure Design of Vehicle-to-Everything (V2X) Communications
- Implement IEEE 1609.2 certificate management and message signing procedures for DSRC-based safety messages while managing certificate revocation list (CRL) distribution latency.
- Configure pseudonym certificate pools for C-V2X to balance privacy preservation with traceability requirements during forensic investigations.
- Integrate secure time synchronization mechanisms to prevent replay attacks in V2X message exchanges without relying on GPS availability.
- Design secure roadside unit (RSU) authentication workflows that prevent rogue infrastructure from injecting false traffic advisories.
- Enforce message rate limiting and source validation at the V2X stack to mitigate distributed denial-of-service attacks from compromised vehicles.
- Validate the cryptographic agility of V2X implementations to support migration from ECDSA to post-quantum digital signatures as standards evolve.
Module 3: Hardening In-Vehicle Wireless Technologies (Bluetooth, Wi-Fi, NFC)
- Enforce secure pairing policies in Bluetooth Low Energy (BLE) key fobs using just-works vs. secure connections based on threat context and user experience trade-offs.
- Isolate infotainment Wi-Fi hotspots from critical CAN or Ethernet domains using hardware-enforced network segmentation and firewall rules.
- Disable unused wireless profiles and services (e.g., Wi-Fi Direct, OBEX) in production ECUs to reduce attack surface.
- Implement secure firmware update mechanisms for wireless co-processors that cannot rely on the main ECU’s HSM for signature validation.
- Configure NFC controllers to reject card emulation mode outside authenticated maintenance sessions to prevent unauthorized diagnostics access.
- Monitor for rogue wireless access points masquerading as legitimate vehicle hotspots using 802.11w management frame protection.
Module 4: Secure Over-the-Air (OTA) Software and Configuration Updates
- Design dual-signed update packages requiring both manufacturer and fleet operator signatures for enterprise vehicle deployments.
- Implement delta update verification procedures that prevent rollback attacks while minimizing bandwidth consumption in low-connectivity regions.
- Enforce secure boot chain validation after OTA updates, including measurement of updated firmware into Trusted Platform Module (TPM) registers.
- Configure update retry logic to prevent denial-of-service via repeated failed update attempts that exhaust ECU storage or processing resources.
- Integrate secure rollback protection by storing monotonic counters in write-once memory to prevent downgrade to vulnerable firmware versions.
- Coordinate OTA update scheduling across dependent ECUs to maintain vehicle operability during partial update failures.
Module 5: Telematics and Cellular Interface Security
- Enforce mutual TLS authentication between the telematics control unit (TCU) and backend servers using embedded hardware-backed certificates.
- Implement secure SIM lifecycle management, including remote provisioning (eSIM) and decommissioning procedures for lost or stolen vehicles.
- Filter and validate incoming SMS commands to the TCU to prevent unauthorized remote actions like door unlocking or engine start.
- Configure cellular modem firmware update processes with secure rollback prevention and integrity checks independent of the host ECU.
- Monitor for IMSI-catchers by analyzing unexpected changes in cellular tower signal strength and encryption downgrade patterns.
- Segregate diagnostic data streams from consumer-facing services (e.g., navigation, streaming) within the TCU’s data handling pipeline.
Module 6: Intrusion Detection and Anomaly Monitoring for Wireless Channels
- Deploy CAN IDS sensors to detect wireless-originated anomalies such as unexpected ECU reprogramming requests from the infotainment gateway.
- Establish baselines for normal wireless communication patterns (e.g., Bluetooth connection frequency, Wi-Fi scan intervals) to detect probing behavior.
- Correlate wireless interface logs with vehicle state (e.g., ignition off, parked) to flag suspicious remote access attempts.
- Implement rate-based thresholds on wireless-initiated diagnostic requests to mitigate brute-force attacks on UDS services.
- Integrate ECU-level execution monitoring to detect code injection resulting from wireless protocol stack vulnerabilities.
- Forward encrypted IDS alerts to backend security operations centers using authenticated, low-latency channels without exposing raw vehicle data.
Module 7: Security Testing and Validation of Wireless Systems
- Conduct protocol fuzzing on Bluetooth stack implementations using tools like AFL or Boofuzz to uncover memory corruption vulnerabilities.
- Perform wireless penetration testing using software-defined radios (SDRs) to simulate rogue base stations and man-in-the-middle attacks.
- Validate secure key storage in wireless ECUs by attempting physical extraction using JTAG and chip-off techniques in lab environments.
- Test resilience of V2X message validation under high-load conditions to ensure safety-critical messages are not dropped during congestion.
- Verify secure disposal of cryptographic keys in decommissioned or repurposed telematics units.
- Assess the effectiveness of RF shielding and jamming detection mechanisms in preventing unauthorized wireless access during physical vehicle inspections.
Module 8: Incident Response and Forensics for Wireless Attacks
- Preserve RF log metadata (e.g., signal strength, channel usage, timestamps) during wireless intrusion investigations for timeline reconstruction.
- Isolate compromised wireless ECUs using remote disable commands while maintaining minimal connectivity for forensic data exfiltration.
- Recover and analyze firmware images from wireless co-processors to identify persistent malware or backdoors.
- Coordinate with mobile network operators to obtain call detail records (CDRs) for forensic correlation during telematics-based attacks.
- Document chain-of-custody procedures for wireless modules removed from vehicles for laboratory analysis.
- Implement secure remote wipe policies for embedded wireless credentials without disrupting critical vehicle functionality.
