Self-recovery Service Securing Edge Server in IoT Network against Ransomware Attack

摘要

Edge server takes an important role in IoT networks that distributes the computing power in the network and serves as a temporary storage for IoT devices. If there is any ransomware attack to the edge server, its network segment will be paralyzed, raising the data integrity and accuracy issues in the IoT system. In this paper, we propose a self-recovery method, called Self-Recovery Service (SRS), which can detect ransomware signature and recover victim files automatically. No interruption to the operation of edge server would be caused by ransomware. SRS is evaluated in the simulation test and the result shows that SRS takes insignificant system resources for its operation that does not degrade the performance of the edge server.
