主流网络代理安全性分析

Security Analysis of Mainstream Network Proxy

目前随着互联网的快速发展,从个人用户到企业、政府机构等通过网络代理连入互联网的方式非常普遍,一方面通过网络代理能够有效改善本地网络状况;另一方面也可解决目前IP地址资源有限的问题,同时也可对内部计算机进行一定的权限控制。首先介绍了目前几种主流的网络代理,然后结合各种网络代理实现原理在用户认证、代理服务等方面进行分析比较,最后研究了目前的代理在云计算安全中的作用。

Nowadays,with rapid development of the internet,it is common for individual users,enterprises and government agencies to access the internet through network agent.On the one hand,the local network condition is effectively improved through network agent,on the other,the problem of limited IP address resource can also be solved,and meanwhile certain access control can be exerted on the internal computer.This paper firstly describes several current mainstream network agents,then combined with a variety of network proxy implementation,analyzes and does comparisons on some aspects like user authentication,proxy service,and finally discusses the role of agent in cloud computing security.
