RESEARCH AND ANALYSIS OF EMAIL PROTECTION AGAINST THREATS

Abstract

Abstract. The article is devoted to the problem of e-mail protection from threats and suggests measures to improve the security and reliability of e-mail correspondence. The Internet is now the mainstay of computer networking technology. Every organization uses the Internet, and they want to protect their information and data. E-mail is one of the most common means of communication in the world. However, as the number of users and the volume of messages sent increases, so does the number of threats that can harm the user and the organization. There are several ways to solve this problem, and one of them is a VPN, a virtual private network. It provides the comfort of an open network and protects the private network by creating a tunnel between the two parties, the sender and the receiver. This paper covers the following tasks: comparison of different types of algorithms, ciphers and protocols; analysis and study of types of network security; study of standards, methods and protocols. With the ever-growing Internet, the communications infrastructure is also growing, and the structure of the network in which computer communications are provided is becoming more complex. In addition to the many benefits it offers, the Internet has become a platform where the importance of information security is at its highest level because of attackers. Small, medium and large institutions and organizations provide their data exchange, for which information security is important, using special lines reserved for them by Internet service providers, due to the fact that the Internet is not secure. However, the high cost of these lines, lack of security and scalability led to the concept of private virtual network (VPN). When using a private virtual network in an unsecured Internet environment, data is exchanged securely using a virtual network.
