The accelerated growth of Internet of Things (IoT) exposes many unsecured issues related to design and usage of devices leading to a new technological security paradigm. This paper presents an evaluation method and corrective actions to be carried out in order to make the usage of IoT devices safer. This method combines both the developer’s perspective and user’s perspective, thus differing from current guides. The proposed evaluation method is divided by categories, each one composed of security control clauses and their corresponding action recommendation. The user perspective of such evaluation method was applied into a service company, and the developer perspective into an IoT device manufacturer. These experiments produced useful perceptions on such view points. The evaluation provided an opportunity to enhance manufacturer security awareness and improve user experience with IoT devices.
