计算机网络已经渗透到社会生产、生活的各个领域。一方面,作为一种信息传播媒介,计算机网络本身具有优越性,它打破了人类传统交流方式,在信息的便捷流通中构建了新型的社会存在形式;另一方面,由于计算机网络的开放性、互联性,再加上本身存在的技术弱点和人为的疏忽,网络安全面临各种风险。所以,研究规避风险的对策是当前一大时代课题,具有重大现实意义。 Computer networks have infiltrated all areas of social production and life. On the one hand, as an information media, the computer network itself has advantages. It breaks the traditional way of human communication and constructs a new form of social existence in the convenient circulation of information. On the other hand, due to the openness of the computer network, Interconnectivity, coupled with its own technical weaknesses and human negligence, poses a variety of risks to cybersecurity. Therefore, studying the measures to evade risks is a topic of a great era and of great realistic significance.
