Module 2: Threat Intelligence and Risk Assessment Integration

• Subscribe to automotive-specific threat intelligence feeds (e.g., Auto-ISAC) and operationalize data into risk models.
• Conduct STRIDE or TARA (Threat Analysis and Risk Assessment) exercises during concept and design phases of vehicle systems.
• Classify vehicle components by attack surface (e.g., telematics, infotainment, ADAS) and prioritize assessments accordingly.
• Map identified threats to MITRE ATT&CK for Vehicles to maintain a standardized threat taxonomy.
• Update threat models quarterly or after major software/hardware changes to reflect evolving attack vectors.
• Integrate threat intelligence into vulnerability management workflows to prioritize patching based on exploit likelihood.
• Document assumptions and limitations in threat models to prevent overconfidence in risk mitigation.
• Require third-party penetration test findings to be fed back into the threat assessment repository.

Module 3: Secure Product Development Lifecycle (SPDLC) Implementation

• Embed cybersecurity requirements into system requirements specifications (SysRS) using traceable identifiers.
• Enforce mandatory security checkpoints at phase gates in the vehicle development process (e.g., concept approval, prototype, SOP).
• Define secure coding standards for C, C++, and AUTOSAR-based systems with static analysis tooling integration.
• Conduct architecture risk analysis (ARA) for each ECU or domain controller design before hardware freeze.
• Require threat modeling outputs to be reviewed and signed off by designated security architects.
• Implement binary composition analysis (BCA) to detect open-source components with known vulnerabilities in build artifacts.
• Define secure boot and secure update requirements early in the development cycle to avoid retrofitting.
• Enforce mandatory security training for development teams tied to project access privileges.

Module 4: Supply Chain and Third-Party Risk Management

• Require Tier 1 and Tier 2 suppliers to provide evidence of ISO/SAE 21434 compliance or equivalent process maturity.
• Conduct on-site cybersecurity audits of critical suppliers handling safety-relevant software or hardware.
• Include contractual clauses mandating disclosure of cybersecurity incidents within 24 hours of detection.
• Enforce use of signed software bills of materials (SBOMs) for all delivered software components.
• Validate supplier vulnerability disclosure processes through tabletop exercises or simulated incidents.
• Implement a supplier risk scoring system based on component criticality, development location, and historical incident data.
• Restrict use of unapproved third-party libraries or development tools in supplier codebases.
• Require suppliers to participate in coordinated vulnerability disclosure (CVD) programs managed by OEMs.

Module 5: Vulnerability Management and Disclosure Operations

• Establish a vulnerability coordination center (VCC) with defined intake, triage, and response workflows.
• Define SLAs for vulnerability validation, impact assessment, and patch development based on severity (CVSS scoring).
• Implement a bug bounty program with clear scope, safe harbor terms, and payment criteria for researchers.
• Coordinate public disclosure timing with regulatory requirements and field fleet exposure.
• Maintain a vulnerability database with fields for component, affected models, exploit status, and mitigation status.
• Integrate vulnerability data with field monitoring systems to detect exploitation attempts in real-world fleets.
• Develop patch deployment strategies that account for OTA update capabilities and dealership service intervals.
• Conduct post-mortem reviews for critical vulnerabilities to identify systemic process gaps.

Module 6: Incident Response and Forensic Readiness

• Define incident classification criteria specific to automotive systems (e.g., CAN bus intrusion, OTA compromise).
• Develop playbooks for vehicle-specific incidents such as fleet-wide denial of service or key fob relay attacks.
• Integrate vehicle telematics data into SIEM platforms for real-time anomaly detection and correlation.
• Establish secure data preservation protocols for ECU memory and log extraction post-incident.
• Pre-negotiate access agreements with law enforcement and regulatory bodies for forensic data sharing.
• Conduct red team exercises simulating supply chain compromise or insider threat scenarios.
• Ensure forensic tools are compatible with automotive protocols (e.g., UDS, DoIP) and ECU architectures.
• Train dealership and service networks on initial response steps for suspected cyber incidents.

Module 7: Over-the-Air (OTA) Update Security Governance

• Define cryptographic signing requirements for OTA update packages using hardware-secured keys.
• Implement rollback protection mechanisms to prevent downgrade attacks on ECU firmware.
• Enforce multi-person authorization for production OTA deployment approvals.
• Conduct pre-deployment validation of OTA updates in representative vehicle fleets under test conditions.
• Monitor OTA delivery infrastructure for anomalies indicating compromise (e.g., unexpected server access).
• Design OTA update scheduling to minimize vehicle downtime and safety risks during transmission.
• Log all OTA transactions with immutable audit trails stored off-vehicle for forensic use.
• Define fallback mechanisms for failed updates, including recovery modes and dealership intervention paths.

Module 8: Regulatory Compliance and Audit Preparedness

• Maintain evidence dossiers for UNECE R155 and R156 compliance accessible during audits.
• Conduct internal gap assessments against regulatory requirements at least annually or after major product changes.
• Document risk acceptance decisions with technical and business justification for auditor review.
• Ensure cybersecurity management system (CSMS) documentation reflects actual operational practices.
• Train auditors within the organization on automotive-specific compliance expectations and evidence formats.
• Coordinate with notified bodies for audit scheduling and evidence submission timelines.
• Map internal controls to specific regulatory clauses to streamline audit responses.
• Implement version control for all compliance documentation to support audit trail integrity.

Module 9: Cybersecurity Metrics and Continuous Monitoring

• Define KPIs such as mean time to patch, vulnerability density per million lines of code, and threat detection rate.
• Deploy ECU-level intrusion detection systems (IDS) with centralized telemetry aggregation.
• Establish baselines for normal vehicle communication patterns to detect deviations in real time.
• Integrate cybersecurity metrics into executive dashboards with benchmarking against industry peers.
• Conduct quarterly red team assessments to validate detection and response capabilities.
• Use fleet-wide telemetry to identify anomalous behavior indicative of zero-day exploitation.

• Review and adjust monitoring thresholds based on vehicle usage patterns and environmental factors.

Module 10: Strategic Risk Communication and Stakeholder Alignment

• Develop tailored cybersecurity briefing templates for executives, board members, and investors.
• Translate technical risk assessments into business impact statements for non-technical stakeholders.
• Coordinate public messaging with legal and PR teams during vulnerability disclosures or incidents.
• Establish regular cybersecurity update cycles for product development teams and program managers.
• Facilitate workshops to align engineering constraints with business risk tolerance levels.
• Document decision rationales for high-risk trade-offs (e.g., feature delivery vs. security testing).
• Engage with regulators proactively to shape emerging standards and demonstrate compliance posture.
• Manage disclosure of security features to avoid creating attacker incentives through publicity.
