UNECE R155 / R156

UNECE R155 & R156 Compliance for Connected Vehicles

CyberWhiz helps automotive manufacturers, suppliers, and mobility technology providers align with R155/R156 cybersecurity and software update regulations through hands-on technical cybersecurity expertise.

Mandatory for Vehicle Type Approval in Many Global Markets
UNECE R155 and R156 are mandatory regulations for vehicle type approval across many countries, including the European Union.

Preparing Automotive Systems for Cybersecurity and OTA Compliance

Connected and software-defined vehicles are increasingly exposed to cyber threats through wireless interfaces, ECUs, mobile applications, cloud platforms, and over-the-air (OTA) update mechanisms.

UNECE R155 and R156 introduce mandatory cybersecurity and software update management requirements for vehicle manufacturers and their supply chains.

CyberWhiz supports OEMs, Tier-1 suppliers, EV manufacturers, and mobility technology companies in building secure automotive systems aligned with UNECE expectations.

UNECE R155 - Cyber Security Management System (CSMS)

UNECE R155 requires vehicle manufacturers to establish and maintain a Cyber Security Management System (CSMS) covering the entire vehicle lifecycle.

Manufacturers must demonstrate that cybersecurity risks are continuously identified, assessed, mitigated, and monitored across:

• In-vehicle networks (CAN, Ethernet, LIN)
• ECUs and embedded systems
• Wireless interfaces (Wi-Fi, Bluetooth, LTE, V2X)
• Backend cloud platforms
• Mobile applications
• OTA infrastructure
• Supply chain components

The regulation also requires manufacturers to validate cybersecurity through testing, risk analysis, and continuous monitoring activities.

UNECE R156 - Software Update Management System (SUMS)

UNECE R156 focuses on secure software update processes for vehicles and connected automotive systems.

Manufacturers must implement a Software Update Management System (SUMS) capable of securely managing:

• OTA update mechanisms
• Software integrity validation
• Update traceability
• Version management
• Secure deployment processes
• Rollback and recovery procedures
• Update approval workflows

The regulation ensures that vehicle software updates do not introduce cybersecurity or safety risks during the operational lifecycle of the vehicle.

How CyberWhiz Supports UNECE R155 & R156 Compliance

CyberWhiz works closely with leading automotive manufacturers and mobility technology providers to help them achieve UNECE R155/R156 cybersecurity and software update compliance.

For UNECE R155 compliance, we support vehicle manufacturers throughout the cybersecurity validation and vehicle type approval process. Our team has performed embedded penetration testing, ECU security assessments, and TARA (Threat Analysis and Risk Assessment) activities for major automotive companies including Otokar and Karsan. We also provide secure manufacturing and deployment capabilities through our End-of-Line (EOL) tooling infrastructure, enabling vehicle software to be securely provisioned and validated during production.

CyberWhiz has extensive experience in automotive penetration testing activities required for type approval readiness and cybersecurity assurance processes. In this context, we have collaborated with organizations such as BMC, Ford Otosan, and Anadolu Isuzu on automotive cybersecurity penetration testing and validation activities.

For UNECE R156 compliance, we help OEMs establish secure end-to-end Software Update Management Systems (SUMS). Together with Otokar and Karsan, we have designed and implemented secure OTA infrastructures covering the entire update ecosystem, from in-vehicle central electronic control units (ECUs) to cloud backend servers, OTA orchestration systems, and web management dashboards. Our approach ensures software integrity, authenticity, traceability, and secure deployment throughout the vehicle lifecycle.

With expertise spanning embedded systems, vehicle communications, backend security, mobile applications, and cloud infrastructure, CyberWhiz provides the technical capabilities required to support secure connected vehicle platforms and UNECE compliance programs.
