IoT Cybersecurity Testing

Security for all devices
in the Internet of Things

IoT cybersecurity audits target the security of all devices on the Internet of Things (IoT). These devices include sensors and actuators as well as back-end connections and optionally communicate with gateways and smartphone apps – security measures to protect against threats should be set up accordingly.

Why IoT cybersecurity?

Digital networking in particular makes applications and components of mobile or static IoT devices vulnerable to attacks. To access a networked device, three main targets are attacked: the device itself, the network and the infrastructure (app, cloud). However, the security of the networked environment, for example in industry, can prevent such external access or IoT attacks. Elements of holistic IoT cybersecurity include:

  • Secure application
  • Robust design
  • Trustworthy handling of private data
  • Update/upgrade of firmware and software
  • Security against attacks on the data validity and authenticity of the communication partners

Cybersecurity testing according to the Radio Equipment Directive
- Regulation (EU) 2022/30, Article 3.3 (d), (e) and (f)

The Radio Equipment Directive (RED Directive) 2014/53/EU sets the legal framework for all products that use radio technologies. The main defined requirements are health and safety, electromagnetic compatibility and efficient use of radio frequencies. Manufacturers and suppliers of these products must demonstrate compliance with RED in the EU market by providing a type examination based on technical documentation (TD) or a declaration of conformity (DoC) and CE marking.

Since 2022, the topic of IoT cybersecurity has also been defined in the RED and thus provides manufacturers with specifications as to which device security requirements must be taken into account in the future:

  • In January 2022, the Delegated Regulation EU 2022/30 was published in the Official Journal of the EU. This regulation supplements parts of Article 3.3 of the RED and thus becomes relevant for manufacturers of products with wireless technologies who want to place their products on the EU market.
  • Delegated Regulation EU 2022/30 defines requirements in the area of cybersecurity for products covered by the RED. This relates in particular to letters d) to f) of Article 3.3:
    • “d) the radio equipment does not interfere with the network or its operation, nor does it misuse network resources, causing an unacceptable degradation of service
    • e) the radio equipment contains security measures to ensure that the personal data and privacy of the user and the subscriber are protected
    • f) the radio equipment supports certain functions that ensure protection against fraud.”

Delegated Regulation (EU) 2022/30 – Radio equipment types

RED Article 3.3 point (f)
(protection from fraud)
any internet-connected radio equipment to transfer money, monetary value or virtual currency (Directive (EU) 2019/713)

  • payment


Originally, the new requirements for sections d) to f) of Article 3.3 were to come into force as early as August 1,2024 and thus become mandatory for affected manufacturers in a timely manner. However, the European Commission has now issued an extension of the transition period, so that the new cybersecurity requirements will come into force on August 1, 2025. Manufacturers must test their products against the new cybersecurity requirements and declare compliance with Delegated Regulation EU 2022/30. This affects both devices that are newly approved and devices that enter the EU market after August 1, 2025.

Even though the deadline has now been postponed by the EU Commission and the standards are currently not yet harmonized, we can already help you with the topic of IoT cybersecurity. With the involvement of our notified bodies, we test your products according to the cybersecurity requirements of the RED and support you in the declaration of conformity. Secure your devices now for the time after August 1, 2025 – with our expertise in the field of IoT device security, we make sure your devices are prepared for future requirements and regulations.

IoT Cybersecurity testing according to
ETSI EN 303 645 and ETSI TS 103 701

ETSI EN 303 645 defines essential security requirements for IoT devices intended for consumers. Thanks to its universal focus, the standard can cover a wide range of IoT devices, from fitness trackers to smart fridges. This standard is primarily aimed at the manufacturers of these devices. These have the option of voluntarily integrating the requirements during the development process (security by design) and implementing them in the manufacture of their products:

ETSI EN 303 645 – Essential requirements

  • Defines basic cybersecurity requirements for consumer IoT devices, but does not include testing or testing procedures
  • Covers all types of consumer IoT devices
  • Includes 33 mandatory requirements and 35 recommendations, including:
    • No universal default passwords
    • Implement a system to manage security vulnerability reports
    • Keeping software up to date
    • Securely storing sensitive security parameters
    • Communicate securely
    • Ensure software integrity
    • Ensuring the security of personal data
    • Make systems resilient to failures
    • Review system telemetry data
    • Easy deletion of user data by the user
    • Ease of installation and maintenance of equipment
    • Validation of input data
    • Data protection requirements
  • Is not suitable to become a harmonized standard under the RED (Radio Equipment Directive)
  • Harmonized standards under RED must contain requirements that are verifiable beyond reasonable doubt (unambiguous test results: yes or no). However, ETSI EN 303 645 contains several result-oriented provisions (e.g. implementation of cryptographic best practices) that are not testable in this way.

Another document that can be used for IoT cybersecurity testing is ETSI TS 103 701. The specification helps manufacturers to design networked devices securely from the outset (security by design). At the same time, it acts as an internationally recognized benchmark for assessing minimum cybersecurity requirements for devices. The specification describes how conformance can be defined and comprehensively tested in accordance with the ETSI EN 303 645 security standard.

ETSI TS 103 701 – Conformity assessment of basic requirements

  • Describes how to assess the compliance of consumer IoT devices with ETSI EN 303 645
  • Contains 109 tests

ETSI TS 103 701 ensures that test results of the security properties of IoT devices are comparable. This enables experienced IoT experts to make accurate safety assessments. Manufacturers have the option of using the test specification for self-testing or having their products evaluated by a testing body.

The cybersecurity tests according to ETSI EN 303 645 and ETSI TS 103 701 can be performed in the cetecom advanced laboratories. We are happy to help you on the way to cyber security for your devices.
