Ensuring computer security of the node by its parametric adjustment under resource constraints

Implementation of the infrastructure of modern organizations based on information technology plays an important role in the formation and development of complex management structures. The various tasks that organizations face require continuous and constant growth of quantitative indicators of the eff eness of these organizations as part of the daily tasks of forming and modernizing new activity models. The signifi of this leads to the need to analyze further possible ways to develop the information infrastructure, which is reduced to separate, allocated computer nodes. Information circuits of modern organizations include a large number of computer nodes. These computer nodes are vulnerable to unauthorized attacks. Such attacks lead to deterioration of their basic nodal characteristics. Deterioration aff the economic performance of organizations. The aim of the work is to develop an analytical model of a computer node and to formulate an optimization problem based on it to adjust the node parameters. An approach based on analytical modeling is considered. The approach allows you to adjust the parameters of the computer node. This adjustment can compensate for incoming unauthorized intrusions. The approach is based on the use of queuing systems. A multichannel queuing system with buff is considered. On the basis of its analytical model the optimization problem is constructed. The solution of the optimization problem with the use of known methods allows to obtain the required parameters of the computer node. Their installation is a necessary adjustment to compensate for incoming unauthorized intrusions. The resulting approach allows to control the computer node when changing the input fl w of applications. The performance value determined by the formulas obtained in the article is the optimal performance value of the computer node. This value can be set by the node management tools on it, depending on the intensity values obtained from the node monitoring subsystems. Read more...
