Module 3: Threat Intelligence and Risk Assessment Integration

Integrating real-world automotive threat intelligence (e.g., from Auto-ISAC) into periodic risk assessment updates for audit validation.
Selecting a risk assessment methodology (e.g., ISO/SAE 21434 TARA) that produces auditable, defensible risk treatment decisions.
Documenting rationale for accepting residual risks above organizational thresholds, including management sign-off for audit evidence.
Ensuring threat scenarios include supply chain compromise vectors when auditing Tier 1 and Tier 2 suppliers.
Validating that threat modeling outputs are traceable to specific vehicle system architectures and software components.
Updating threat libraries annually and demonstrating revision control during audit walkthroughs.
Using attack trees to justify security control investments in response to high-impact threats during audit defense sessions.
Reconciling discrepancies between internal risk assessments and external auditor findings through root cause analysis.

Module 4: Audit Planning and Scope Definition

Determining whether to conduct process audits, product audits, or a hybrid approach based on organizational maturity and regulatory pressure.
Defining the audit scope to include over-the-air (OTA) update infrastructure, backend services, and mobile applications.
Selecting audit frequency for high-risk suppliers based on their cybersecurity maturity and historical performance.
Allocating audit resources between development phases (e.g., concept, design, production) to ensure lifecycle coverage.
Deciding whether to include legacy vehicle platforms in audit scope when they lack modern security controls.
Establishing criteria for selecting sample systems (e.g., ADAS, infotainment) to represent broader cybersecurity posture.
Coordinating audit schedules with product development milestones to avoid conflicts with critical delivery dates.
Defining audit success criteria in measurable terms (e.g., % of findings resolved within 90 days) for executive reporting.

Module 5: Third-Party and Supply Chain Audits

Requiring Tier 1 suppliers to provide evidence of internal cybersecurity audits as part of procurement contracts.
Assessing supplier cybersecurity maturity using standardized questionnaires (e.g., VDA QMC) during audit planning.
Conducting on-site audits of suppliers developing safety-critical software to verify secure coding practices.
Handling audit findings related to subcontracted software development where the primary supplier lacks visibility.
Enforcing encryption and secure transfer protocols for audit data exchanged with suppliers.
Requiring suppliers to report cybersecurity incidents within 24 hours as a contractual audit control.
Validating that supplier patch management processes meet OEM timelines for vulnerability remediation.
Using audit findings to trigger supplier risk reclassification and potential procurement de-certification.

Module 6: Technical Audit Procedures and Evidence Collection

Specifying acceptable forms of audit evidence (e.g., logs, configuration files, penetration test reports) for each control.
Using static application security testing (SAST) results as evidence for secure coding compliance during software audits.
Verifying cryptographic key management practices through direct inspection of HSM configurations and access logs.
Conducting live system inspections of ECU firmware to confirm secure boot implementation.
Requiring version-controlled documentation of cybersecurity requirements and design decisions for traceability.
Validating that intrusion detection systems (IDS) generate auditable alerts with sufficient forensic detail.
Collecting network traffic captures from vehicle test benches to verify segmentation and firewall rules.
Using fuzz testing outcomes as evidence of resilience against malformed input in communication stacks.

Module 7: Incident Response and Audit Trail Maintenance

Reviewing incident response playbooks to ensure they include forensic data collection procedures for audit purposes.
Verifying that SOC analysts preserve chain-of-custody for vehicle-related incident evidence during investigations.
Ensuring vehicle-generated logs are retained for a minimum of six months to satisfy audit and regulatory requirements.
Testing log integrity mechanisms (e.g., hashing, write-once storage) to prevent tampering during audit validation.
Mapping incident classifications to severity levels that trigger specific audit reporting obligations.
Conducting post-incident audits to evaluate response effectiveness and update controls accordingly.
Integrating vehicle telematics data into SIEM systems to support correlation during cybersecurity investigations.
Documenting decisions to withhold public disclosure of vulnerabilities based on coordinated vulnerability disclosure policies.

Module 8: Product Lifecycle and Change Management Controls

Requiring cybersecurity impact assessments for all engineering change requests (ECRs) affecting E/E architecture.
Verifying that software updates undergo cybersecurity regression testing before release approval.
Tracking cybersecurity requirements through change control boards to prevent unauthorized deviations.
Conducting audits of end-of-life (EOL) processes to ensure secure decommissioning of vehicle backend systems.
Enforcing dual approval for production environment changes involving security-critical configurations.
Validating that configuration baselines for ECUs are stored in version-controlled repositories accessible to auditors.
Reviewing design freeze exceptions to assess cybersecurity risk implications during audit reviews.
Ensuring that cybersecurity test results are re-validated after any software or hardware change in the development pipeline.

Module 9: Audit Reporting and Remediation Oversight

Classifying audit findings using a standardized severity scale (e.g., critical, high, medium, low) for consistent tracking.
Assigning remediation owners and deadlines for each finding, with escalation paths for overdue items.
