Abstract: With the rapid development of the Internet, the frequency and breadth of the network social activities among college students are constantly expanding, and the hidden dangers of network information security are also increasing. In this paper, we put the college students in Chengdu as the research object, and use self-made questionnaire to investigate the basic information of students, network information security awareness, protective behavior and demand. The results show that the information security awareness of students is weak, the information security of personal network is not enough, the information security accidents of university students occur frequently, the female college students are not as good as the male students in the network information security consciousness and protection; they expect full-time teachers and courses to carry out network information security education. It is suggested that colleges should strengthen the education of network information security of university students, improve their network information security awareness, strengthen the network information security protection ability and reduce the harm caused by information security accidents.
