【摘要】 利用基于策略的网络管理PBNM(policybasednetworkmanagement)的思想,提出了一种基于网络流数据分析和挖掘的方法来实现对网络安全状态的持续感知;在此基础上定义了一种访问控制策略描述语言,能够自动根据网络安全状态生成相应的控制策略规则,提供一种持续的网络安全控制能力。更多还原

【Abstract】 According to the principle of PBNM(policy based network management),a method based on analyzing and mining the network traffic is proposed to be aware of the network security status.With this mechanism an access control policy is defined.The policy rules are generated automatically in terms of the network security status and the policy action decision-making mechanism.A con-tinuous capability of network security control is provided.更多还原
