In the information society, people rely more and more on the Internet. However, with the rapid development of the Internet, cyber security seems to have become a huge potential problem. Under the bright prospects of network development, the issue of network information security has clouded a dark cloud. Although China’s computer manufacturing industry has made great strides, its core components manufacturing technology is still very weak. Computer software development and development are also subject to the monopoly of foreign markets, especially the operating system, so the current use of a large number of computer software and hardware from outside the country, which makes our country’s network security problems have to be
