摘要： 对多级分布式的大型网络进行集中安全管理，可以有效提高网络的安全防御能力和安全管理效率，成为网络安全研究的一个迫切问题。本文阐述一种多级分布式安全管理系统（MD-SMS Multilevel and Distributed Security Management System），首先描述其体系结构，然后讨论三个关键问题的解决：设备建模、通信机制和协同处理，最后以Worm_Sasser蠕虫为例，分析其网络协同防御能力。
Abstract: In recent years, how to defend worms and attacks in a large-scale network has been an urgent problem. This paper proposes a Multilevel and Distributed Security Management System (MD-SMS) which can manage security devices over multilevel and distributed networks. We firstly describe its architecture, then discuss three key problems, lastly we bring forth its effect on cooperated defense based on an example of Worm_Sasser.
