Determination of suitability of network intrusion de­tection rules and their mathematical evaluation

Abstract

The article deals with the problems that arise when detecting network at­tacks using intrusion detection systems in the corporate network of an enter­prise. The features of the formation of signatures of network attacks are con­sidered. The problem of coincidence of parameters of network intrusions and parameters of damaged packets is investigated. To assess the suitability of the rules for detecting network attacks and their subsequent control, a method for upgrading the component composition of intrusion detection systems has been redesigned. A method of mathematical evaluation of the suitability of the rules for detecting network attacks is considered.

Human-machine interface for process automation

Abstract

The paper considers the process of car body painting at a factory. The quality of the body coating directly affects the service life of the vehicle. Mod­ern painting lines at facilities are equipped with robotic equipment. Using ro­bots allows to do painting work with high precision and less wastes. The hu­man-machine interface allows to control and manage complex production pro­cesses. The results of designing the operator's monitoring panel for tracking processes on the robotic line for car body painting are presented.
