TOOL OF PREVENTING UNAUTHORIZED ACCESS TO DATA NETWORK

Abstract

Security of the data networks has always been an object of great attention. Its importance caused by sufficient lag in developmentrate of levels of network security comparing to rates of development of network technologies. A large increase in the number of network users and their access to information, mainly via the Internet, which facilitates the implementation of destructive actions, results in a necessity of comprehensive approach to network security. Although these destructive actions have not always aimed tomalicious purposes, even such attempts may often lead to large losses, information leakages, etс. The paper describes the algorithm tool that allows identifying an unauthorized access in the data network. This tool is capable to solve the common tasks of network security in complex cooperation with other software and hardware approaches. In addition, the advantages and disadvantages of similar means were examined and analyzed. A code listing of scanning module tool and its overall practical software implementation are presented.
