Обоснование норм безопасности информации медицинских информационных систем с использованием методов эволюционного моделирования

Abstract

The analysis of a problem a substantiation of norms of safety of medical information of information systems in the form of quantitative requirements to security indicators is carried out. Mathematical statement of a problem of rationing of requirements to safety of the information of medical information systems is put in the form of an optimizing problem. On the basis of the comparative analysis of methods of the decision of optimizing problems with reference to the mathematical expression formalizing model of protection of the information, the algorithm of rationing based on methods of evolutionary modeling of protection of the information in medical information systems is offered. Use of genetic algorithms for the decision of optimizing problems of rationing of requirements to safety of the information allows to overcome a number of problems arising at application gradient methods in connection with a multi-peak kind of function conforming and a considerable quantity of optimized parameters. With use of the special software intended for realization of genetic algorithms from structure of the environment of mathematical calculations Matlab rationing of requirements to safety of the information is spent. As initial data the standard data containing in the most known popular database of realization of threats of safety of the information accumulated DARPA are used. Results of rationing of requirements safety are led to the information of medical information systems with use of evolutionary modelling at connection to a network "Internet" according to standard levels of realization of threats of safety of the information.
