Modal verbs terminology
In the present document "should", "should not", "may", "need not", "will", "will not", "can" and "cannot" are to be

Introduction
The growth of the Internet of Things has spurred the development of security requirements for IoT devices. ETSI
EN 303 645 [i.1] provides baseline cyber security provisions for a wide range of Consumer IoT products and remains
outcome focused. While ETSI TS 103 701 [i.3] deals with the assessment of conformance of IoT products against the
provisions of ETSI EN 303 645 [i.1], the present document has been developed to guide manufacturers on its
implementation, by providing non-exhaustive examples of practical solutions that can be used to meet these provisions.
Additionally, the examples provided herein are not limitative; it is possible to meet the provisions in ETSI
EN 303 645 [i.1] by using other solutions.

1 Scope
The present document serves as guidance to help manufacturers and other stakeholders in meeting the cyber security
provisions defined for Consumer IoT devices in ETSI EN 303 645 [i.1] and ETSI TS 103 645 [i.2].
The present document is complementary to ETSI EN 303 645 [i.1] and ETSI TS 103 701 [i.3]. It explains the
relationship between these specifications and how they can be used together. It also provides a non-exhaustive set of
example implementations that can be used to meet the provisions of ETSI EN 303 645 [i.1] and ETSI TS 103 645 [i.2],
noting that not all possible implementations are included. Where relevant, pointers to supporting specifications are
provided. Usage by industry players as well as future development of standards, such as specialisation into precise use
cases, or certification aspects, are being given consideration.
