随着计算机网络技术的迅猛发展和Internet的广泛使用,各高校的计算机网络也由一个传统的封闭式实验教学网络,发展成为开放式的信息资源共享和信息传输网络。但大量的不安全因素使得高校的计算机网络安全面临着重大威胁。因此,如何构建一个安全、可信的教育和科研计算机网络体系,使其适应网络技术和应用的新变化,从而更好的为高校教育服务是值得我们探讨的。 With the rapid development of computer network technology and the extensive use of the Internet, the computer networks of universities are also developed from an open and closed experimental teaching network to an open information resource sharing and information transmission network. However, a great deal of insecurity poses a serious threat to the computer network security in colleges and universities. Therefore, how to construct a safe and credible education and research computer network system to adapt to the new changes of network technology and application, so as to better serve the higher education is worth discussing.
