This curriculum spans the technical and procedural rigor of a multi-phase automotive cybersecurity integration project, comparable to designing and deploying a vehicle-wide firewall system across development, validation, and fleet operations teams.

Module 1: Threat Landscape and Attack Surface Analysis in Automotive Systems

  • Conducting a vehicle-level attack surface inventory, including all ECUs, communication buses (CAN, LIN, Ethernet), and wireless interfaces (Bluetooth, Wi-Fi, cellular).
  • Mapping known automotive cyber threats (e.g., CAN injection, ECU reprogramming, telematics gateway exploitation) to specific vehicle subsystems.
  • Integrating threat intelligence from sources like ISO/SAE 21434, UNECE WP.29, and CVE databases into risk assessment workflows.
  • Identifying high-risk entry points such as OBD-II ports, mobile app interfaces, and over-the-air (OTA) update mechanisms.
  • Assessing the impact of third-party components and supplier-provided software on the overall threat model.
  • Documenting threat scenarios with likelihood and impact ratings to prioritize firewall placement and rule sets.

Module 2: Firewall Architecture Design for In-Vehicle Networks

  • Selecting between centralized (gateway-based) and distributed firewall architectures based on vehicle E/E topology and performance constraints.
  • Defining firewall placement at domain boundaries (e.g., between infotainment and powertrain domains) to enforce segmentation.
  • Specifying hardware requirements for firewall nodes, including processing power, memory, and real-time OS support for deterministic packet filtering.
  • Designing stateful vs. stateless inspection capabilities based on protocol complexity and latency tolerance of safety-critical systems.
  • Integrating firewall functionality into existing gateway ECUs without degrading routing performance or CAN-to-Ethernet bridging.
  • Establishing trust zones and defining inter-zone communication policies using zone-based firewall models.

Module 3: Protocol-Specific Filtering and Deep Packet Inspection

  • Developing CAN ID whitelists and payload length filters to block malformed or unauthorized messages on critical buses.
  • Implementing deep packet inspection for Ethernet-based protocols like SOME/IP and DoIP, including service and method-level filtering.
  • Configuring firewall rules to detect and block diagnostic session abuse (e.g., unauthorized UDS services on CAN).
  • Handling protocol encapsulation scenarios, such as tunneling CAN over IP, without creating blind spots in inspection.
  • Addressing timing-based attacks by enforcing inter-message timing constraints in firewall rule logic.
  • Managing exceptions for legitimate but anomalous traffic patterns during ECU initialization or fault recovery.

Module 4: Integration with Vehicle Security Management Systems

  • Synchronizing firewall rule updates with the vehicle’s Security Operations Center (SOC) via secure OTA channels.
  • Forwarding firewall logs and alert events to an onboard Intrusion Detection System (IDS) for correlation and anomaly detection.
  • Configuring firewall behavior in response to security state changes, such as switching to lockdown mode after intrusion detection.
  • Integrating with Hardware Security Modules (HSMs) to validate digital signatures on rule update packages.
  • Establishing secure communication channels between firewalls and the central security manager using TLS or IPSec.
  • Implementing secure fallback mechanisms when security management systems are offline or compromised.

Module 5: Rule Management and Policy Lifecycle Governance

  • Developing version-controlled firewall rule sets aligned with vehicle software release cycles.
  • Creating role-based access controls for rule modification, limiting changes to authorized engineering and security teams.
  • Conducting pre-deployment rule validation using simulation environments to prevent unintended communication disruptions.
  • Establishing rollback procedures for firewall configurations in case of rule-induced system failures.
  • Documenting rule rationale and mapping each rule to specific threat mitigations for audit compliance.
  • Rotating and deprecating rules during vehicle lifecycle updates, especially after ECU replacements or feature deactivations.

Module 6: Performance, Latency, and Real-Time Constraints

  • Measuring firewall processing latency under peak load to ensure compliance with real-time deadlines for safety-critical messages.
  • Optimizing rule evaluation order to minimize inspection overhead on high-frequency signals (e.g., brake pedal position).
  • Allocating dedicated CPU cores or hardware accelerators for firewall operations in multi-core gateway ECUs.
  • Implementing bypass modes for non-critical buses during ECU diagnostics to avoid interference with service tools.
  • Validating firewall resilience under denial-of-service conditions, such as high-volume spoofed message floods.
  • Monitoring memory usage to prevent buffer exhaustion from log accumulation or state table growth.

Module 7: Compliance, Auditing, and Certification Requirements

  • Aligning firewall design and operation with ISO/SAE 21434 requirements for cybersecurity engineering processes.
  • Preparing evidence for UNECE WP.29 R155 cybersecurity management system audits, including firewall configuration records.
  • Implementing immutable logging for firewall events to support forensic investigations and regulatory reporting.
  • Conducting penetration testing that includes firewall bypass attempts and rule evasion techniques.
  • Documenting security assumptions and limitations in the firewall’s design for safety certification (e.g., ISO 26262 ASIL alignment).
  • Coordinating with third-party testing labs to validate firewall effectiveness as part of vehicle type approval.

Module 8: Field Deployment, Monitoring, and Incident Response

  • Designing remote monitoring dashboards to track firewall drop rates, rule triggers, and anomaly patterns across vehicle fleets.
  • Implementing secure, bandwidth-efficient log aggregation from vehicles to backend security operations platforms.
  • Developing incident playbooks for responding to sustained firewall alerts, including ECU isolation procedures.
  • Updating firewall rules in response to emerging threats while maintaining backward compatibility with older vehicle models.
  • Conducting post-incident forensic analysis using firewall logs to determine attack vectors and lateral movement paths.
  • Managing end-of-life firewall support, including rule deactivation and secure decommissioning of cloud-connected components.
