This curriculum spans the technical and organisational complexity of a multi-workshop automotive cybersecurity integration program, addressing segmentation across design, deployment, and operational lifecycle stages in a manner comparable to OEM-led initiatives involving internal engineering teams, supplier coordination, and compliance validation.

Module 1: Threat Landscape and Regulatory Requirements in Automotive Networks

Assessing attack surfaces across CAN, LIN, Ethernet, and wireless interfaces in modern vehicle architectures.
Selecting applicable regulatory frameworks such as UN R155, ISO/SAE 21434, and regional data privacy laws for segmentation compliance.
Mapping adversary tactics from MITRE Auto to inform segmentation boundaries and zone definitions.
Evaluating third-party component supply chain risks that introduce unsegmented communication paths.
Integrating threat intelligence feeds specific to automotive OEMs into segmentation design reviews.
Documenting segmentation rationale to support audit requirements during type approval processes.

Module 2: Architectural Principles for In-Vehicle Network Segmentation

Defining trust zones based on functional safety (ISO 26262 ASIL levels) and cyber risk exposure.
Implementing hardware-enforced boundaries between powertrain, infotainment, and ADAS domains.
Selecting gateway placement in domain-centralized vs. zone-based E/E architectures to enforce segmentation.
Designing data diodes or unidirectional gateways for OTA update distribution without bidirectional exposure.
Allocating bandwidth and prioritization policies across segmented networks to prevent denial-of-service.

Validating update package signatures before allowing cross-zone propagation from telematics to domain controllers.
Enforcing rollback protection mechanisms to prevent downgrade attacks on segmented ECUs.
Coordinating segmentation rules with delta update strategies to minimize cross-zone data transfer.
Testing update failure modes to ensure segmentation does not block recovery or safe fallback operation.
Monitoring update traffic patterns for anomalies indicating lateral movement attempts post-compromise.

Module 5: Diagnostics and Service Access Control
