Abstract:

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 secur ity 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.

Key words: VPN, security policy, policy rule, security policy management
