UBM – UVM Approach for Preventing Insider Data Theft from Cloud Storage

摘要

A huge number of internet users are employing cloud computing for data storage. As a result, proper security in potentially vulnerable areas of cloud storage technology has become a major point of concern for the users contracting with a cloud service provider. Strong and robust techniques for securing data on the cloud are thereby a compulsive need to the cloud service providers, to provide reliable service and cloud storage service users, to rely on the service providers. For securing data on the cloud, encryption and sophisticated user access are major techniques used. But these techniques corroborate to be weak in preventing data theft attacks when the data thief is a malevolent insider to the cloud service provider. In this paper, we propose a two-layered approach for securing data in the cloud using user behavior monitoring (UBM) and user verification mechanism (UVM) once any data thief is suspected by our detection system.
