The OEM’s Guide to Vehicle Cybersecurity

Accelerating Software-Defined Vehicles Without Regulatory Friction.

A Brand's Worst Nightmare

"Your engineering is excellent. Your bikes ride beautifully. Then a security researcher posts a video showing how your connected model can be hacked — and the press asks one question: where is your cybersecurity documentation?"

Mechanical excellence is no longer enough. As two-wheelers integrate connectivity, the first manufacturer publicly exposed for a security flaw — without ISO/SAE 21434 evidence or UN R155 compliance to stand behind — won't just face a recall. They'll lose the narrative. Competitors, media and regulators are already watching

What's Inside

01

The Security Imperative & SDV Revolution

02

Decoding the Mandates: UN R155 / R156 vs ISO 21434

03

The Shift-Left Philosophy

04

Anatomy of a Compliant Architecture

05

Continuous Monitoring & VSOC

06

Legacy Systems Strategies

The Connected Vehicle Is Already Here

Cars already run on 100 million lines of code. Two-wheelers are next: connected dashboards, telemetry, OTA, smart keys..

"Cybersecurity is no longer just a data privacy issue; it is a critical functional safety hazard."

Data Center

The Law vs. The Blueprint

The Audit

UN R155 / R156

The legal framework. Mandatory implementation of a Cybersecurity Management System (CSMS).


STATUS: MANDATORY FOR TYPE APPROVAL
The Textbook

ISO/SAE 21434

The engineering methodology. How to design, produce, and maintain security throughout the lifecycle.

STATUS: GLOBAL ENGINEERING STANDARD

The "Shift-Left" Strategy

Don't bolt security on at the end. Embed it at the core.

1
Concept
2
TARA Analysis
3
Design

Executing Threat Analysis and Risk Assessment (TARA) during the concept phase allows you to specify exact security requirements before a single line of code is written.

HSM Modules

Hardware-based isolation for critical cryptographic keys and operations.

Secure Boot

Ensuring only authenticated software runs on your vehicle controllers.

Secure Comm

Encrypted internal bus communication (CAN/Ethernet) to prevent injection.

Cyber Ops

Continuous Monitoring

Compliance doesn't end at the factory gate. You need a Vehicle Security Operations Center (VSOC) to monitor the fleet 24/7.

  • Real-time anomaly detection
  • Automated regulatory reporting
  • Secure OTA Update deployment

Saving Legacy Systems

How do you secure a 10-year-old ECU with zero cryptographic power?
Zonal Architectures and Security Gateways.

By placing vulnerable legacy systems behind high-performance secure domain controllers, we create a defensive perimeter without requiring a hardware overhaul.
