However, there are also many network se- curity problems. To deal with it, this article explores the computer applications based on management of network in- formation security technology. It analyzes the main factors threatening network information security from the security problems caused by computer applications. Combining with the application practice, specific measures are put forward for reference. Keywords: Network Information; Security Technology; Management; Computer Application 1. Introduction While bringing convenience to the whole world, computer network causes some negative effects. These security loopholes pose a great threat to people’s privacy and corporate confidential information. It is obvious that with the rapid development of information technology, the relationship between network security and people’s life and financial security is getting closer and closer. Thus, the research of computer applications based on management of network information security technology has become the focus at this stage. On this basis, specific protection strategies are designed according to the cor- responding factors. 2. Security problems caused by computer applications Network information security is to ensure the nor- mal and stable operation of the network, including pro- tecting the data information, software and hardware sys- tems in the network from being tampered with, destroyed or leaked [1] . The rapid development of computers has created convenient conditions for network information and data transmission, with increasing number of com- puter applications. However, if the security problems cannot be successfully solved, the rights and interests of users may suffer from seriously negative influence, and the hardware and software systems of computers may be damaged. At present, there is no mature management system of network information security technology in China, leaving many problems unsolved in the practical application, and further affecting the popularization of computer applications in China. Security problems in computer applications include the following aspects. First, stealing information. The computer system it- self has a certain protection function to ensure the secu- rity of information inside the application, but loopholes in the system enable criminals to steal information dur- ing information transmission or storage process.
