随着互联网应用的迅速发展，各种网络安全威胁不断出现。本文介绍了网络安全所呈现的特点以及目前所面临的形势。攻击方法的更新、攻击技术的提升以及攻击范围的扩大给应急工作带来了考验。应急工作的管理现状存在一定的问题，在核心技术、安全保障方面都比较落后。借鉴传统领域的应急体系，改善当前应急技术措施成为网络安全工作的重要部分。针对新时期的网络安全应急工作环境，提出了调动体系力量，多方联动的消除方法，从体制和机制等方面来进行保证，以防止网络威胁产生的巨大影响。

Considering the emergence of recent network security threats, this article presents network security features and the current situation. Updated attack methods, enhanced attack technology, and expanded attack scope have changed emergency work. Some problems exist in emergency management of the status quo; the core technology and security assurance are relatively backward. Learning from the emergency response system in traditional areas in order to improve current emergency technical measures becomes an important part of network security. In this paper, the author proposes a multi-linkage elimination method that can mobilize system strength and protect against network threats based on the system and the mechanism.
