摘　　要：分析了当前网络维护管理和安全防护体系在网络自身运行状态监控方面存在的不足,提出一种网络边界安全守护的方法,主要解决了现有网络应用中无法全面监控网络结构的变化和无法详细了解网络边界接入状况的问题。通过使用多线程周期扫描和SNMP陷阱技术获取实时的网络信息,并将其与存储的历史信息进行比对,将异常状态以醒目的图形标示在管理界面上并发送报警通知,使得网络管理人员能够实时掌握网络结构与边界的状态变化,对于异常的接入情况能够及时采取管制措施,保障信息网络的边界安全。The paper analyses the shortcomings of the network status monitoring which existing in the current network management and security guard system, a secure network topology monitoring and boundaries .guarding method are put forward. It mainly solves problems that can not comprehensive monitor the change of network structure and detailedly find out the unknown boundary accessing. According to the result of periodically scanning with multi-thread, checking with historical information, the abnormal state will be labeled by striking color on the management interface. Additionally, the network manager enable to master network topology and boundaries variation real-time and take measures to block the invalidate access from internal network in time to ensure the security of the information network boundaries.
