Research And Implementation Of An IoT Internet Security Solution Based On Virtualization

The rapid development of IoT(Internet of Things) brings us great convenience, but it does not take into account the security risks. In this paper, we find the shortcomings of traditional IoT system security solutions, and put forward an isolated security system which is more suitable for IoT system. The system takes advantage of virtualization technology, and consists of internet intrusion detection, memory forensics, system defense&recovery, and personalized customization modules. It provides a perfect recovery mechanism so that the IoT system is self-healing according to strategies which users had configured. This system overcomes the problem of tight coupling, single function, recovery incapable and some other drawbacks of traditional security system.In this paper, we analyze the problems and shortcomings of existing works about internet security technology. Combined with the IoT environment, we propose improvement measures in coupling, system defense and restoration, expansibility, and performance. Finally, we compare the new system with old ones in function and performance aspects, and hope to resolve security risks in IoT system. So that we can provide a fully functional, efficient internet security service for IoT system.
