Algorithms for determining illegal activities in the network in providing information security

Algorithms for detecting illegal activities in the network are mentioned in this article. Currently, the development of economic and social spheres of any country cannot be imagined without modern information technologies. For this reason, the demand and need for information in the whole world is increasing day by day. In particular, the development of information technologies is the reason for the increase in the volume of data. This, in turn, requires a different assessment of information, that is, looking at it as content and creating new relationships, as well as identifying illegal attacks on information. The inbound filters in the aforementioned algorithms increase network security and help with security planning to manage traffic flow. They allow only secure and trusted networks, hosts or autonomous systems access to a secure network, use routers to restrict traffic and define rules and policies that govern a particular port, service, server or network.
