Conducting a threat model using STRIDE to identify risks in keyless entry systems, tire pressure monitoring systems (TPMS), and remote diagnostics interfaces.
Mapping wireless attack vectors such as relay attacks on passive keyless entry (PKE) systems and signal jamming during authentication.
Assessing the risk of over-the-air (OTA) software update channels being exploited to deliver malicious firmware via compromised cellular or Wi-Fi gateways.
Documenting adversary capabilities, including low-cost software-defined radios (SDRs) used to capture and replay CAN messages transmitted over Bluetooth.
Integrating vehicle-specific threat intelligence feeds into security operations to detect emerging wireless exploits targeting infotainment platforms.
Performing red team exercises to simulate wireless attacks on vehicle-to-everything (V2X) communication stacks under real-world driving conditions.

Module 2: Secure Wireless Protocol Design and Implementation

Implementing geographic revocation policies for compromised vehicle certificates based on jurisdictional and deployment zone boundaries.
Testing edge cases in V2X stack behavior when receiving malformed or out-of-sequence messages under high RF interference conditions.

Enforcing runtime application sandboxing for third-party apps using Android Automotive OS security policies.

Module 5: Over-the-Air (OTA) Update Security Architecture

Designing a dual-signature scheme where both the OEM and a trusted backend sign firmware images before deployment to prevent insider threats.
Validating hash chains in delta updates to ensure intermediate patches have not been tampered with during transmission.
Implementing secure rollback protection to prevent attackers from downgrading ECUs to vulnerable firmware versions.
Configuring OTA clients to authenticate update servers using certificate pinning with short-lived, auto-rotated TLS certificates.
Establishing a secure staging environment to test OTA packages for unintended side effects on wireless subsystems before fleet rollout.
Enforcing ECU-level access control so only authorized modules can accept and apply OTA updates via the telematics gateway.

Module 6: Wireless Intrusion Detection and Anomaly Monitoring

Deploying RF fingerprinting systems to detect cloned key fobs by analyzing subtle timing and modulation differences in transmitted signals.
Correlating CAN bus activity with wireless events (e.g., BLE unlock followed by unexpected diagnostic commands) to detect staged attacks.
Configuring IDS rules to flag abnormal message frequencies on TPMS networks, which may indicate spoofed sensor data.

Responding to detected anomalies by triggering module-level containment, such as disabling wireless interfaces on compromised gateways.

Module 7: Security Governance and Compliance for Wireless Systems

Aligning wireless security controls with ISO/SAE 21434 requirements for threat analysis and risk assessment (TARA) documentation.
