随着当今网络科技的迅速发展，与此相伴的网络安全问题也越来越受得人们的重视。现有的防御手段在当今的大数据时代只能疲于应对频出的网络入侵等安全事件。针对此问题，文章提出了一种基于云架构的网络安全事件监测系统架构，描述了此系统的结构和主要功能，讨论并实现了其中的关键技术。该系统可以实现蠕虫、DDoS攻击等安全事件的监测，满足了网络安全管理的需求。

英文摘要：

With the rapid development of network technology, network security problems are more important to people. Existing means of defense in the era of big data has been struggling to cope with the frequent network intrusion security events. For this problem, this paper proposes a network security event monitoring system architecture based on cloud architecture, describes the structure and function of this system and the key technologies. The system can monitore security incidents such as worm, DDoS attacks, while meeting the needs of network security management.
