专用网安全隔离关键技术研究

Research on Key Technologies of Security Segregation in Private Networks

互联网技术快速发展,网络安全问题受到广泛重视,尤其是专用网运行过程中,更加注重安全性。笔者首先从数据链路层、网络层及应用层三个方面,围绕专用网的安全隔离技术进行具体的探究,在此基础上,将专用网作为具体的应用对象,分析其对于网络安全隔离技术的应用需求,随后梳理归纳关键的安全隔离技术,总结一套实用性较高的专用网安全隔离技术体系。

With the rapid development of Internet technology,the issue of network security has received extensive attention.Especially during the operation of private networks,more attention has been paid to security.The author begins with specific explorations of the security isolation technology of the private network from the data link layer,network layer and application layer.On this basis,as a specific application object,the private network first analyzes its application requirements for the network security isolation technology,then combs and summarizes the key security isolation technologies,and concludes a set of high-use-dedicated network security isolation technology system.
