The explosive growth in computer systems and networks has increased the role of computer security within organizations. In many cases, ineffective protection against computer security treats leads to considerable damage, and even can cause an organization to be paralyzed. Therefore, the development of new models and methods of performance analysis of security systems seems to be very important. In this paper, the authors propose a model of computer security operation, and introduce its related performance measure. It is shown how the model can be applied to performance evaluation of actual systems. Finally, a technique of security system performance analysis is described and its practical implementation is discussed.
