1.   SCOPE








1.1.


This Regulation applies to vehicles, with regard to cybersecurity, of the Categories M and N.
This Regulation also applies to vehicles of Category O if fitted with at least one electronic control unit.












1.2.


This Regulation also applies to vehicles of the Categories L6 and L7 if equipped with automated driving functionalities from level 3 onwards, as defined in the ‘Reference document with definitions of Automated Driving under WP.29 and the General Principles for developing a UN Regulation on automated vehicles’ (ECE/TRANS/WP.29/1140).












1.3.


This Regulation is without prejudice to other UN Regulations, regional or national legislations governing the access by authorized parties to the vehicle, its data, functions and resources, and conditions of such access. It is also without prejudice to the application of national and regional legislation on privacy and the protection of natural persons with regard to the processing of their personal data.












1.4.


This Regulation is without prejudice to other UN Regulations, national or regional legislation governing the development and installation/system integration of replacement parts and components, physical and digital, with regards to cybersecurity.




2.   DEFINITIONS
For the purpose of this Regulation the following definitions shall apply:






2.1.


‘Vehicle type’ means vehicles which do not differ in at least the following essential respects:






(a)


The manufacturer’s designation of the vehicle type;










(b)


Essential aspects of the electric/electronic architecture and external interfaces with respect to cybersecurity.














2.2.


‘Cybersecurity’ means the condition in which road vehicles and their functions are protected from cyber threats to electrical or electronic components.










2.3.


‘Cybersecurity Management System (CSMS)’ means a systematic risk-based approach defining organisational processes, responsibilities and governance to treat risk associated with cyber threats to vehicles and protect them from cyberattacks.










2.4.


‘System’ means a set of components and/or sub-systems that implements a function or functions.










2.5.


‘Development phase’ means the period before a vehicle type is type approved.










2.6.


‘Production phase’ refers to the duration of production of a vehicle type.










2.7.


‘Post-production phase’ refers to the period in which a vehicle type is no longer produced until the end-of-life of all vehicles under the vehicle type. Vehicles incorporating a specific vehicle type will be operational during this phase but will no longer be produced. The phase ends when there are no longer any operational vehicles of a specific vehicle type.










2.8.


‘Mitigation’ means a measure that is reducing risk.










2.9.


‘Risk’ means the potential that a given threat will exploit vulnerabilities of a vehicle and thereby cause harm to the organization or to an individual.










2.10.


‘Risk Assessment’ means the overall process of finding, recognizing and describing risks (risk identification), to comprehend the nature of risk and to determine the level of risk (risk analysis), and of comparing the results of risk analysis with risk criteria to determine whether the risk and/or its magnitude is acceptable or tolerable (risk evaluation).










2.11.


‘Risk Management’ means coordinated activities to direct and control an organization with regard to risk.










2.12.


‘Threat’ means a potential cause of an unwanted incident, which may result in harm to a system, organization or individual.

If the reporting or response is not sufficient the Approval Authority may decide to withdraw the CSMS in compliance with paragraph 6.8.




8.   MODIFICATION OF VEHICLE TYPE AND EXTENSION OF TYPE APPROVAL








8.1.


Every modification of the vehicle type which affects its technical performance with respect to cybersecurity and/or documentation required in this Regulation shall be notified to the approval authority which approved the vehicle type. The Approval Authority may then either:












8.1.1.


Consider that the modifications made still comply with the requirements and documentation of existing type approval; or












8.1.2.


Proceed to necessary complementary assessment pursuant to paragraph 5, and require, where relevant, a further test report from the Technical Service responsible for conducting the tests.
