Digital Witnesses: trusted devices for Cybersecurity in IoT

Project Overview: 
The Internet of Things (IoT) is growing to be a major global technological force, and also becoming a cornerstone of the European economic fabric in the short and medium term. However, it is also among the environments most threatened by the incessant increase of cybercrime. In this sense, within the IoT, cyber attacks can be perpetrated by any device with minimal computing and communications capabilities, from anywhere, and with total impunity; thus it becomes a problem that is impossible to solve only with existing tools.

This project aims to help solve this problem by introducing a security solution that is radically different from those that have been used until now. In particular, this project proposes the design and development of Digital Witnesses, trusted electronic devices capable of obtaining electronic evidence and safeguarding it in a protected area. Using these devices as a foundation, the IoTest project aims to offer a dynamic solution that will record events on heterogeneous, unpredictable and uncertain scenarios.

Moreover, since existing digital evidence processes and regulations are not prepared to deal with the new cybersecurity issues created by these highly dynamic and distributed scenarios, the deployment of digital witnesses will result on a qualitative advancement in the evolution of electronic evidence management systems, improving their effectiveness in the detection of attacks and identification of cybercriminals.
