Estimation of the boundaries of the region of stable functioning of elements of special-purpose information systems characteristic

In article the methods of imitating modeling realized in the conditions of ensuring unity and the required accuracy of results at assessment of stability of functioning of information structure of security system in the conditions of negative impacts are considered. Assessment of stability of functioning of information structure of security system in the conditions of negative impacts is initially made on the basis of development of model of information exchange of elements of information structures of security systems and negative impacts which is constructed on the basis of the set-theoretic approach allowing not only to describe features of creation of elements of the considered structures, but also to carry out formalization of process of functioning of models of security complexes in the form of creation of the discrete (matrix and vector) model differing in classifications of set of threats. On condition of the continuity of temporary parameters as information systems in the conditions of negative impacts it is possible to present process of functioning of information structures of security systems in the form of the integrated (dynamic) model constructed with use of the differential equations describing conditions of her elements that allows to estimate, in turn, borders of field of steady management of processes of interaction of the specified sets.
