This curriculum spans the full lifecycle of automotive threat modeling, equivalent to a multi-workshop program embedded within a vehicle development organization’s cybersecurity governance, covering governance setup, cross-supplier collaboration, and integration with safety and compliance workflows.

Module 1: Establishing Threat Modeling Governance in Automotive Programs

Define cross-functional threat modeling ownership between systems engineering, cybersecurity, and safety teams within vehicle development programs.
Select and institutionalize a threat modeling methodology (e.g., STRIDE, TARA) aligned with ISO/SAE 21434 and OEM-specific cybersecurity management system (CSMS) requirements.
Integrate threat modeling milestones into phase-gate reviews for ECU and vehicle platform development to enforce compliance.
Develop artifact retention and versioning policies for threat models to support auditability and traceability during type approval processes.
Negotiate access controls and data handling protocols for threat models containing sensitive vehicle architecture details across suppliers and internal departments.
Establish escalation paths for unresolved high-risk threats that impact functional safety or regulatory compliance.

Module 2: Asset Identification and System Boundary Definition

Map electronic control units (ECUs), communication buses (e.g., CAN, Ethernet), and wireless interfaces (e.g., Bluetooth, cellular) to identify all in-scope assets.
Document data flows between ECUs and external entities, including cloud services and mobile applications, using data flow diagrams (DFDs) at appropriate abstraction levels.
Classify assets based on safety impact (e.g., steering, braking) and regulatory relevance to prioritize threat modeling efforts.
Define trust boundaries at physical and logical interfaces, such as between domain controllers and zonal networks, to scope threat analysis.
Resolve discrepancies between network topology documentation and actual vehicle implementations through engineering collaboration.
Identify third-party components (e.g., infotainment modules) with limited interface specifications and assess their impact on boundary completeness.

Module 3: Threat Enumeration Using Industry Frameworks

Apply ISO/SAE 21434 threat categories (e.g., unauthorized access, spoofing) to systematically enumerate threats at each trust boundary.
Customize STRIDE per attack vector (e.g., OBD-II port, OTA update server) to generate actionable threat statements with specific preconditions.
Use attack trees to decompose high-level threats (e.g., remote vehicle takeover) into feasible attacker paths based on known vehicle vulnerabilities.
Correlate identified threats with known vulnerabilities in automotive components (e.g., CVEs in telematics control units) to validate realism.
Document assumptions about attacker capabilities (e.g., physical access vs. remote) to ensure consistent threat severity scoring.
Iterate threat lists with red team findings and penetration test results to close detection gaps.

Module 4: Risk Assessment and Prioritization

Implement a risk matrix that combines likelihood (based on attacker access level and exploit complexity) and impact (on safety, privacy, brand) to score threats.
Adjust risk ratings based on existing controls (e.g., secure boot, firewall rules) and avoid double-counting mitigations in likelihood estimates.
Resolve conflicts between functional safety (ISO 26262) and cybersecurity risk rankings when a component affects both domains.
Document residual risk decisions for high-severity threats where mitigation is technically or economically infeasible.
Use attack feasibility timelines (e.g., immediate vs. long-term) to prioritize near-term mitigations for production vehicles.
Present risk treatment options (accept, mitigate, transfer, avoid) to technical steering committees for formal approval.

Module 5: Mitigation Strategy Development and Integration

Design mitigations that align with OEM security requirements, such as encrypted ECU-to-ECU communication or intrusion detection system (IDS) deployment.
Specify cryptographic key management approaches (e.g., PKI, symmetric key provisioning) for secure communication mitigations.
Coordinate with hardware teams to ensure mitigations like Hardware Security Modules (HSMs) are included in ECU designs before tape-out.
Define secure update mechanisms for software-based mitigations to ensure patchability in the field.
Validate that mitigations do not introduce unacceptable performance degradation on time-critical vehicle networks.
Document mitigation ownership and implementation timelines across supplier and internal engineering teams.

Module 6: Supplier Collaboration and Threat Model Exchange

Define threat modeling deliverables and review cycles in supplier contracts for tier-1 and tier-2 vendors.
Standardize threat model formats (e.g., JSON-based, Visio templates) to enable integration of supplier models into vehicle-level analyses.
Conduct joint threat modeling workshops with key suppliers to resolve interface threats and align on trust boundaries.
Audit supplier threat models for completeness, especially for components with limited OEM visibility (e.g., camera modules).
Negotiate intellectual property constraints when sharing threat models that contain proprietary architecture details.
Track supplier mitigation implementation through integration testing and vehicle-level validation campaigns.

Module 7: Continuous Threat Model Maintenance and Reassessment

Trigger threat model updates based on change requests, such as new ECU features or connectivity additions (e.g., V2X).
Reassess threat models after field incidents or emerging threats (e.g., new attack tools targeting specific ECUs).
Integrate threat model updates into software configuration management systems to maintain version consistency.
Align threat model refresh cycles with vehicle software release schedules for connected features.
Use automated tools to detect deviations between implemented systems and documented models during integration phases.
Archive legacy threat models with metadata to support forensic analysis during incident investigations.

Module 8: Integration with Broader Cybersecurity and Safety Workflows

Link threat model outputs to security test cases in validation plans for compliance with UNECE WP.29 R155.
Map identified threats to intrusion detection rules and SOC monitoring use cases for operational visibility.
Coordinate with functional safety teams to ensure cybersecurity threats affecting ASIL-rated components are jointly assessed.
Feed threat intelligence from fleet monitoring back into threat models to improve future designs.
Align threat model documentation with cybersecurity documentation required for vehicle type approval.
Use threat model data to inform cybersecurity bill of materials (CBoM) generation for vulnerability management.
