Security In Operating System Virtualisation

While server and desktop PCs continually pose problems for IT managers in terms of manageability, flexibility and security, the isolated execution environments provided by virtual machines are one way of addressing such issues. Another advantage is that virtualisation technology can help organisations protect themselves from accidental data leakage if notebook computers are lost.

With increased hardware support for virtualisation by the major microprocessor vendors, virtualisation products are becoming a practical solution for IT management. In this paper, we discuss the management issues around virtualisation technology, as well as the options available for deploying virtualisation technology in both server and desktop environments.
