Risk in systems with virtualization : test case analysis

The paper presents an approach to risk analysis of exemplar test case information systems. Authors point out the common practice to implement virtualization and put away security considerations for future[5]. The overview of virtualization techniques, focusing on server virtualization is given. Next, authors present risk analysis of exemplar GIS system. First of all identification of threats is taken out focusing on virtualization aspects, but it also includes common threats for both that could have a significant impact on safety when using a virtualization. The risk assessment for the test case system was performed using qualitative method. Assessment of the likelihood and magnitude of impact of identified risks was performed on the basis of the expert’s knowledge and experience. The obtained results were used to develop risk rankings, which indicate the risks that need special attention when designing and managing a virtual system.
