A Logging Model for Enabling Digital Forensics in IoT, in an Inter-connected IoT, Cloud Eco-systems

Rapid advancement in the smart device technologies have accelerated the deployment of Internet-of-Things (IoT) to control, monitor or to exchange information of any real world systems and improve the quality of life. The IoT allows to create a network of billions of devices, using multitude of communication and data processing technologies, supporting varying business needs both in civilian settings and sensitive applications. This also creates an increased footprint for security vulnerabilities and cyber-attacks. Therefore, the security and digital forensics capabilities have to be built into the design of the IoT. In this work, we summarized the IoT forensic challenges and defined the IoT forensic requirements. We then proposed a conceptual event logging model and design architecture to support digital forensics in IoT, for an integrated IoT-Cloud computing environment. The model exploits the power of the Cloud computing, same time complements the deficiencies of IoT, utilizing an integrated environment.
