Abstract

With the rapid development of computer technology in China, network information technology has brought great convenience to people. It is widely used in all aspects of people's production and life, including finance, scientific research, education and other fields. It is related to the economic interests of the country, making network attacks everywhere, especially for the global open network information, local and even global network information loopholes Occurrence, network information security form research, strengthen network information technology security is related to national security, national development. Especially in the era of globalization and information, once data leakage occurs, the loss caused is immeasurable. Therefore, it is of great significance to advocate network security and constantly strengthen the construction of network information security to protect the overall image and interests of enterprises. Based on this, based on the overview of network information technology and its vulnerability, this paper discusses the common network attack methods, puts forward relevant strategies, and analyzes the Countermeasures of network security construction, so as to eliminate the hidden dangers of network information security and provide theoretical basis for creating a good network information environment.
