Network-based virus analysis and defense strategies
Abstract：With the rapid development of network technology, the network virus has gradually become a big challenge in the field of network security. Network viruses, with their concealment, diversity and intelligence, have brought serious threats to the network security of individuals, enterprises and even countries. These viruses spread through the Internet, infect computer systems, destroy system functions, steal sensitive information, and even lead to economic losses and social disorder. Therefore, this paper aims to conduct an in-depth analysis of network viruses and propose effective defense strategies. First, the article outlines the definition, classification, transmission mode, and infection mechanisms of network viruses, including transmission based on file sharing, infection using network vulnerabilities, and diffusion in the cloud environment. Then, the article reveals the problems of network virus defense, such as the lack of traditional defense mechanism, the imperfect network security regulations and the lack of user awareness of prevention. In view of these problems, the paper puts forward the strategic planning of strengthening the construction of the new defense mechanism, improving the network security laws and regulations, enhancing the user prevention awareness and skills training, and balancing the defense cost and technology investment. Through the research of this paper, it aims to provide beneficial reference and reference for the field of network security, reduce the possibility of network virus invasion, and reduce the economic loss and social impact.
