Description

This curriculum spans the technical and procedural rigor of a multi-workshop threat modeling and secure architecture engagement, matching the depth required for an OEM to design, audit, and operate remote access systems in alignment with automotive-specific standards and real-world attack surface management.

Module 1: Threat Modeling for Vehicle Remote Access Systems

Decide whether to adopt STRIDE or attack tree methodologies based on OEM threat intelligence maturity and regulatory alignment.
Map remote access entry points (telematics unit, mobile app, OTA backend) to MITRE ATT&CK for Automotive to prioritize mitigation.
Document attacker capabilities assuming compromised mobile device or stolen user credentials in threat scenarios.
Integrate threat model outputs into system architecture reviews to enforce security-by-design in telematics control units.
Update threat models quarterly to reflect new attack vectors observed in industry ISAC reports.
Align threat model scope with UNECE WP.29 R155 requirements for audit readiness.

Module 2: Secure Authentication and Identity Management

Implement mutual TLS between mobile apps and backend APIs using hardware-backed key storage on user devices.
Enforce multi-factor authentication for high-privilege actions such as remote start or door unlock via push notification or FIDO2.
Design short-lived JWTs with vehicle-specific claims to limit lateral movement after token compromise.
Integrate vehicle identity into enterprise IAM systems using standardized claims formats (e.g., OIDC vehicle extensions).
Manage lifecycle of vehicle-to-cloud certificates including revocation via OCSP stapling in low-bandwidth conditions.
Balance user convenience against security by configuring re-authentication intervals for session persistence.

Module 3: Secure Communication Architecture

Segment remote access traffic using V2X security gateways to isolate CAN bus from cloud-facing services.
Deploy encrypted tunnels (IPsec or DTLS) between telematics units and cloud endpoints with hardware-accelerated crypto.
Enforce strict cipher suite policies aligned with NIST recommendations, excluding weak or deprecated algorithms.
Implement certificate pinning in mobile applications to prevent MITM attacks via rogue CA compromises.
Optimize payload encryption for low-latency commands (e.g., remote horn) without sacrificing integrity checks.
Monitor for anomalous traffic patterns indicating tunneling or covert channels within legitimate remote access sessions.

Module 4: Backend Infrastructure Security

Design zero-trust access policies for cloud microservices handling remote vehicle commands using SPIFFE identities.
Isolate command processing workloads in dedicated VPCs with egress filtering to prevent lateral cloud compromise.
Apply least privilege IAM roles to services that validate and forward remote access requests to vehicles.
Implement audit logging for all remote command executions with immutable storage and SIEM integration.
Conduct regular penetration testing on public-facing APIs used for remote access initiation.
Enforce input validation and rate limiting on all endpoints to mitigate DoS and injection attacks.

Module 5: In-Vehicle Security Enforcement

Deploy secure gateways to enforce access control policies before remote commands reach critical ECUs.
Implement secure boot and runtime integrity monitoring on telematics control units to detect tampering.
Configure ECU firewalls to reject unauthorized remote diagnostic or control messages based on source zone.
Use hardware security modules (HSMs) in vehicle networks to offload cryptographic operations for command validation.
Log all remote access attempts at the gateway level with time synchronization for forensic correlation.
Design fallback modes that disable remote functions when security monitors detect anomalies or violations.

Module 6: Over-the-Air (OTA) Update Security

Sign OTA update packages using dual-controlled keys in HSMs with split custody between security and engineering teams.
Verify update authenticity and integrity on the vehicle using public key infrastructure before installation.
Implement delta updates with cryptographic consistency checks to prevent partial or corrupted installations.
Enforce secure rollback policies that prevent downgrade to vulnerable firmware versions.
Coordinate OTA deployment windows to minimize exposure during update transmission and application.
Monitor for spoofed update servers by validating domain certificates and enforcing DNSSEC on update resolution.

Module 7: Incident Response and Forensics

Define escalation paths for confirmed unauthorized remote access incidents involving legal, PR, and regulatory teams.
Preserve vehicle and cloud logs with chain-of-custody procedures for potential regulatory investigations.
Simulate remote compromise scenarios in red team exercises to validate detection and containment playbooks.
Deploy remote kill switches for telematics units with multi-person authorization requirements.
Integrate vehicle telemetry into SOCs with correlation rules for anomalous remote access patterns.
Conduct post-incident reviews to update threat models and controls based on actual attack data.

Module 8: Regulatory Compliance and Audit Readiness

Map remote access controls to specific clauses in UNECE R155 and ISO/SAE 21434 for compliance documentation.
Maintain evidence of security validation for remote access components during third-party audits.
Implement data residency controls for remote access logs to comply with GDPR and CCPA requirements.
Document risk acceptance decisions for legacy vehicle platforms lacking modern cryptographic support.
Coordinate with legal teams to define data retention periods for remote command audit trails.
Prepare technical evidence packages for regulators demonstrating secure design and operational controls.
