Preemptive Cyber Response Strategy and IoT Forensic Evidence

With the development of IoT technology, the use of IoT terminals connected with smart phones is increasing. At the same time, security incidents are occurring. IoT security incidents can be linked to risk at both a personal and national level through social disruption and cyberterrorism. In this study, we analyze the security infringement environment in an IoT smart watch device. We extract forensic evidence from the watch, using a hashing function to verify data integrity, and create a forensic report to be used as legal evidence of a cyber attack point of origin. Finally, we suggest that IoT smart terminals are infiltration targets and that preventive measures and accountability should be adopted in order to form a preemptive response to attacks as part of national cyber security.
