ETSI EN 303 645 is a cybersecurity standard developed by the European Telecommunications Standards Institute (ETSI) for consumer Internet of Things (IoT) devices. It establishes a set of baseline requirements to ensure devices are secure by design, addressing key areas such as data protection, software updates, and vulnerability reporting. This standard is useful as it provides manufacturers with a clear framework to mitigate security risks, enhancing consumer trust and protecting user data. In the methods-and-patterns quadrant, ETSI EN 303 645 is particularly relevant as it sets fundamental guidelines for developing secure IoT devices, emphasizing the need for security considerations during the design phase. The adoption of this standard is encouraged due to the increasing prevalence of IoT devices and the associated security challenges, making it crucial for organizations involved in IoT development to prioritize security best practices.
