VPN系统中安全策略系统的设计与实现

VPN技术是解决网络端到端连接的安全问题的一条有效途径,其中的关键方面就是建立适合网络需求的安全策略,而安全策略由一条或多条描述特定行为的规则组成。本文对安全策略模块进行了研究,提出了一个安全策略模型,分析了安全策略管理器中规则的角色和状态转换并加以实现。实验结果表明,VPN系统工作正常,性能稳定。

Design and Implementation of the Security Policy System in VPN Systems

The VPN technology is an efficient way to solve the end-to-end security problem in networks. The most pivotal aspect is to build the fit network security policies, which consist of one or more rules that describe the specific actions. This paper studies the security policy module, proposes a security policy model,and analyses the roles and the state translation of rules in security policy management tools. The results of experiment show that our VPN system can work normally and steadily.
