Research on Key Technologies of Network Security Multidimensional Dynamic Risk Assessment

Abstract

The emergence of the Internet has had a huge impact on people’s lives and work. In the 21st century, human society has fully entered the Internet age. Through the Internet, people can realize zero-distance, data transmission and information sharing without time and space restrictions. The network has become an important tool for modern people to obtain information, disseminate and share information, and has been applied to almost all fields, from scientific research to astronomy, national defense, medical care, small to home entertainment, production office, web browsing must use the network. However, network security issues have always restricted the application of the network. The network has the characteristics of openness, complexity and speciality. Some lawless elements will steal other people’s information and finance through cyber attacks. The network security problem cannot be ignored. It is important to do a multi-dimensional dynamic risk assessment of network security. This paper will conduct research and analysis on the key technologies of network security multi-dimensional dynamic risk assessment.
