A context-centered methodology for IoT forensic investigations.

The weakness of the security measures implemented on Internet of Things (IoT) devices, added to the sensitivity of the data that they handle, has created an attractive environment for cybercriminals to carry out attacks. This has caused a substantial increase in the number of cyberincidents, requiring the opening of digital investigations in order to shed light on what has occurred. However, the characteristics of this new environment, such as its variety of contexts, make it impossible to use the methodology followed until now in conventional analysis. Therefore, a new common procedure is needed to ensure that IoT examinations are carried out in a complete and efficient manner. In this article, after reviewing the methodological requirements of IoT forensics, and studying the suggestions made by the research community, a methodology to perform investigations in a certain context of the IoT environment is proposed. In addition, its practicality is evaluated in three different security incident scenarios, proving its effectiveness and appropriateness to be used in future cases. [ABSTRACT FROM AUTHOR]
