About Cybersecurity Labelling Scheme for IoT - CLS(IoT)

Introduction

In recent years, there has been an exponential increase in the number of connected Internet of Things (IoT) devices in the world. It is estimated that there will be some 50 billion IoT devices in use around the world by 2030^[1].

Amidst the growth in number of IoT products in the market, and in view of the short time-to-market and quick obsolescence, many consumer IoT products have been designed to optimise functionality and cost over security. As a result, many devices are being sold with poor cybersecurity provisions, with little to no security features built-in.

This poses cybersecurity risks such as the compromise of consumers’ privacy and data as hackers generally look for the easiest systems to attack that will net the most damage and returns.

Compromised IoT devices can also be used by threat actors to form a botnet to launch Distributed Denial of Service (DDoS) attacks which could bring down Internet services. One example of this is the Mirai botnet attack in 2016 which were carried out via innocuous IoT devices, such as home routers and IP cameras. The attack left much of the internet inaccessible in the US East Coast.

Currently, information on the amount of security that is built into these devices is not made readily available by the manufacturers. Thus, consumers are unable to make informed decisions towards purchasing more secure devices.

About the Cybersecurity Labelling Scheme

The Cyber Security Agency of Singapore (CSA) has launched the Cybersecurity Labelling Scheme (CLS) for consumer smart devices, as part of efforts to improve Internet of Things (IoT) security, raise overall cyber hygiene levels and better secure Singapore's cyberspace.

The CLS(IoT) is the first of its kind in the Asia-Pacific region. Under the scheme, smart devices will be rated according to their levels of cybersecurity provisions. This will enable consumers to identify products with better cybersecurity provisions and make informed decisions.

The CLS(IoT) also aims to help manufacturers stand out from their competitors and be incentivised to develop more secure products. Currently, consumer smart devices are often designed to optimise functionality and cost. They also have a short time-to-market cycle, where there is less scope for cybersecurity to be incorporated into product design from the beginning.

The CLS(IoT) was first introduced to cover Wi-Fi routers and smart home hubs. These products were prioritised because of their wider usage, as well as the impact that a compromise of the products could have on users. It has since been extended to include all categories of consumer IoT devices, such as IP cameras, smart door locks, smart lights and smart printers.

Mutual Recognition

Finland

Singapore and Finland have signed a Memorandum of Understanding (MoU) to mutually recognise the Cybersecurity Labels issued by CSA and the Transport and Communications Agency of Finland (Traficom) in 2021. Under the MoU, Consumer IoT products that have met the requirements of Finland’s Cybersecurity Label are recognised as having met the requirements of Level 3 of Singapore’s Cybersecurity Labelling Scheme, and products with CLS Level 3 and above are recognised by Finland to have met their requirements.

Level 3 and Level 4 applications for consumer connected products may be granted both Singapore’s Cybersecurity Labelling Scheme label and the Finnish Cybersecurity Label at once, with a single application process.

Germany

Singapore and Germany have signed a Mutual Recognition Arrangement (MRA) to mutually recognise the cybersecurity labels issued by CSA and the Federal Office for Information Security of Germany (BSI) in 2022. Under the MRA, smart consumer products issued with Germany’s IT Security Label will be recognised by CSA to have fulfilled Level 2 of Singapore’s Cybersecurity Labelling Scheme, and products with CLS Level 2 and above are recognised by Germany to have met their requirements.

The mutual recognition of cybersecurity labels will apply to devices intended for use by consumers such as Smart Cameras, Smart TVs, Smart Speakers, Smart Toys, Smart Garden and Household Robots, Gateways and Hubs for Home Automation, Health Trackers, Smart Lighting, Smart Plug (Smart Power Socket), and Smart Thermostats.

Republic of Korea

Singapore and Republic of Korea have signed a Mutual Recognition Arrangement (MRA) to mutually recognise Cybersecurity Labels issued by CSA and the Korea Internet & Security Agency (KISA). Under the MRA, smart consumer products issued with KISA’s Certification of IoT Cybersecurity (CIC) and Singapore’s Cybersecurity Label will be mutually recognised in either country.

The ROK’s CIC scheme consists of three levels: Lite, Basic, and Standard, with third party laboratory testing required at all levels. CSA will recognise products issued with CIC Basic Level and above to have fulfilled Cybersecurity Labelling Scheme (CLS)(IoT) Level 3 requirements. Similarly, KISA will recognise products labelled with CLS(IoT) Level 3 and above to have fulfilled CIC Basic Level.

The mutual recognition of cybersecurity labels will apply to devices intended for use by consumers such as smart cameras, smart televisions, smart speakers, smart toys, smart garden and household robots, gateways and hubs for home automation, health trackers, smart lighting, smart plug (smart power socket) and smart thermostats.

United Kingdom

Singapore and the United Kingdom have signed a Memorandum of Understanding (MoU) on cooperation for the mutual recognition of consumer IoT cybersecurity regimes. Under this arrangement, smart consumer products issued with Singapore’s CLS labels will be deemed compliant to the requirements of UK’s Product Security and Telecommunications Infrastructure (PSTI) Act. Similarly, smart consumer products compliant with the UK PSTI requirements may undergo a simplified application process to obtain the CLS(IoT) Level 1 label.

Connectivity Standards Alliance 

The Cyber Security Agency of Singapore (CSA) and the Connectivity Standards Alliance (Alliance) signed a Mutual Recognition Arrangement (MRA) for the recognition of their respective cybersecurity labels for consumer Internet-of-Things (IoT) devices on 19 March 2024.

It facilitates the mutual recognition of cybersecurity labels to reduce duplicated testing and costs for manufacturers, thereby advancing the cyber security of consumer IoT. The MRA also encompasses the exchange and alignment of information related to relevant standards, requirements, and other practices concerning the cybersecurity labelling of consumer IoT. It will foster collaboration on further developments of the respective cybersecurity certification/labelling schemes.
