Tailored Security Measures for Diverse Device Types

The scope of the Radio Equipment Directive extends across a diverse range of wireless devices, each requiring tailored security measures:

1. Mobile devices (smartphones, tablets)

Mobile devices such as smartphones and tablets are ubiquitous in daily life, storing vast amounts of personal and sensitive data. Employing multi-factor authentication (MFA) enhances security by requiring multiple forms of verification (e.g., password, biometric data, security token), reducing the risk of unauthorized access even if one factor is compromised. These measures not only protect personal information stored on the device but also secure access to sensitive applications and services.

To enhance security, manufacturers must implement advanced user verification authentication methods. This could involve biometric recognition technologies like fingerprint scanning or facial recognition, which offer robust and convenient ways to verify user identity.

2. Wearable technology

Wearable devices like smartwatches, fitness trackers, and medical monitors collect and transmit personal health and activity data. Given their continuous interaction with users and other devices, secure data transmission protocols are essential. 

Manufacturers should implement protocols such as Bluetooth Low Energy (BLE) with encryption to ensure that data exchanged between wearables and connected devices (such as smartphones or cloud services) remains confidential and tamper-resistant. Encrypting data at rest and in transit is critical for maintaining privacy and preventing unauthorized access to sensitive user information.

3. Consumer IoT devices

IoT devices encompass a wide range of interconnected smart devices, from smart home appliances to industrial sensors. These devices often operate within complex networks, making them susceptible to cyber-attacks.

How to ensure compliance with RED’s essential requirements?

This task can be challenging as the directive's essential requirements are very generic. The fundamental principle is as follows: manufacturers must ensure that the radio equipment placed on the market is in conformity with the essential requirements of the RED and all applicable EU acts.

To this end the manufacturer needs to carry out conformity assessment to verify that the radio equipment complies with the essential requirements of the RED. This directive provides three possibilities, called conformity assessment procedures of modules A, B+C and H.

Modules A and C pertain to internal production control, involving a verification process executed by the manufacturer to confirm their radio equipment conforms with RED's essential requirements. This process requires comprehensive product testing against RED's requirements, including cybersecurity.

If manufacturers lack the necessary tools or expertise to perform these tests, they must enlist the help of competent bodies, such as an accredited testing laboratory. It's crucial to remember that module A is only permissible if the manufacturer has used all the harmonized standards covering essential requirements. If a product hasn't been fully manufactured according to the harmonized standards listed under RED, a Notified Body must perform the conformity assessment (via Module B or H procedures).

While the European ETSI EN 303 645 standard is commonly used for cybersecurity tests of consumer IoT devices, it isn't a harmonized standard for the RED's cybersecurity requirements. Therefore, a Notified Body should be involved in the conformity assessment for these aspects.

The EU Commission has requested the preparation of harmonized standards to address the three cybersecurity-related aspects of RED’s essential requirements. The EN 18031 series of standards will tackle these requirements. These standards are expected to be published in the first half of 2025. Nevertheless, based on past experience, cybersecurity tests typically take several months. Hence, manufacturers should start planning compliance projects well in advance of the deadline.

Lastly, manufacturers must create technical product documentation containing evidence, such as test reports, to demonstrate compliance with applicable requirements. Upon the completion of this documentation, which verifies full compliance with RED and all applicable EU laws, the manufacturer's representative must sign the EU Declaration of Conformity and affix the CE Marking to the radio equipment.
