Executive Architecture Interpretation

Classification: Inferred from Requirements

The architecture should be read as an ECU/component security architecture with a supplier evidence wrapper around it. The product boundary contains system core behavior, application software, hardware platform, security services, diagnostic/update handling, and logging. Outside the boundary are vehicle networks, diagnostic tools, backend/IT systems, PKI/provisioning, development/ALM tooling, security operations, and OEM/customer approval.

Confidence level: Medium
Classification: Inferred from Requirements

System Boundary

Classification: Inferred from Requirements

The system boundary is the Electric Clutch Actuator ECU security scope plus supplier-controlled lifecycle evidence. Exact vehicle-function allocation remains open.

External Actors

Classification: Inferred from Requirements

OEM/customer, vehicle network/other ECUs, diagnostic/service tools, backend/cloud/IT systems, PKI/provisioning, development/ALM tooling, and security operations.

Major Subsystems

Classification: Inferred from Requirements

System Core, Application Software, Hardware Platform, Security Services, External Interfaces, Backend and IT Systems, Engineering Toolchain, and Compliance Process.

Main Interfaces

Classification: Inferred from Requirements

OEM/customer cybersecurity approval and evidence interface; Diagnostic/service tool to ECU interface; Vehicle network secure data communication interface; Secure update, flash, and IVD interface; Certificate and key provisioning interface; Backend/cloud/IT operational interface; Development, ALM, and evidence tooling interface; Security operations and vulnerability reporting interface; Application software to security services interface; Hardware platform and key storage interface

Main Data Flows

Classification: Inferred from Requirements

Requirements/evidence flow, diagnostic access flow, vehicle data flow, secure update/flash flow, key/certificate flow, security event/logging flow, and vulnerability/incident flow.

Security Architecture Logic

Classification: Recommendation

Protect the highest-risk boundaries first: diagnostics, vehicle network communication, update/flash, key/certificate handling, and backend/tooling evidence. Use traceability and customer approval to keep inferred architecture distinct from confirmed requirements.

What Is Explicitly Required

Classification: Explicit Requirement

Cybersecurity concept documentation, risk assessment input, control derivation and traceability, verification/validation evidence, diagnostic/security controls, key/certificate handling, logging/audit elements, vulnerability and incident handling elements.

What Is Inferred

Classification: Inferred from Requirements

Layered ECU security services, backend/update actors, PKI/provisioning flow, security operations flow, and componentized architecture views.

Key Assumptions

Classification: Expert Assumption

The item is treated as one or more ECUs/E/E components until the customer confirms the exact product item definition.

Open Architecture Decisions

Classification: Needs Customer Clarification

Confirm item definition, network topology, diagnostic roles, update mechanism, PKI ownership, HSM capability, backend ownership, and final TARA outputs.

Recommended Next Design Steps

Classification: Recommendation

Hold an item-definition workshop, confirm boundary diagrams, allocate interfaces and assets, perform TARA, confirm security mechanisms, and update traceability with customer-approved decisions.

Logical Architecture

Classification: Inferred from Requirements

The logical architecture decomposes the Electric Clutch Actuator ECU into System Core, Application Software, Hardware Platform, Security Services, External Interfaces, Backend/IT, Engineering Toolchain, and Compliance Process.

Security Relevance

This view shows where an asset, interface, trust boundary, or evidence obligation could create security risk.

Constraints

No final TARA, topology, algorithm, or implementation ownership is claimed unless a requirement explicitly supports it.

Open Questions

Confirm customer ownership, exact item boundary, allocated mechanisms, and verification evidence for this view.
