Abstract—The growth of networking services has led to an increase of users using these services. Because of the limitation of network infrastructure, each physical server is typically used for deploying a networking service for a group of users. In this model, data is centrally stored; As a result, ensuring its privacy is a critical requirement. In current systems, an administrator could use access control mechanisms provided by operating systems to prevent illegal access. However, these solutions are difficult to deploy and operate. Because of this issue, the administrator has difficulty comprehensively handling data security issues in a shared environment. In this paper, we propose a new approach using virtualization concept for securing data in this shared environment. The approach has been successfully implemented in the Linux environment, and has shown positive results. It can properly solve data security problems in the shared environment and surmount the weaknesses found in current solutions.
Index Terms—Access control, data security, shared environment, virtualization.
