Methods of Security Authentication and Authorization into Informationals Systems

There are many ways to organize authentication and authorization in information systems. Typically, authentication is used to provide login, and authentication is primarily a security tool for personal user data. It is the first level of protection against receiving any system information. In turn, authorization helps ensure data integrity when running multiple different users with different permissions. The security of information and communication systems includes the protection of information circulating in computer systems designed for storing, searching and processing information (databases, application programs, control systems for various devices, etc.) and computer systems intended for disseminating information (Internet, local control and wireless networks, mobile communications, radio communications, satellite communications, etc.), from unauthorized access, counterfeiting and destruction. In our time, the information and communication revolution is the most urgent task, the solution of which is important for security in various areas of human activity that use computer technology and telecommunications. This article considered the existing mechanisms of authentication and authorization, and their advantages and disadvantages that affect the cybersecurity of informational systems. Theoretical and methodological requirements for the use of standardized methods of information systems log in are stated.
