摘要:由于冶金工业工控网络的相对封闭性,目前针对工控系统的攻击以APT(恶意软件为载体)、病毒、木马、勒索软件等恶意程序为主。恶意程序通过自我复制、主动探测、自动传播等方式,可在工业网络内快速扩散,造成网络延迟、主机失效、业务波动,甚至造成物理损坏、业务停产等严重后果,对冶金工业企业安全生产构成极大威胁。

Abstract: Due to the relative closeness of industrial control network of metallurgical industry, the current attacks on industrial control system mainly focus on malicious programs such as APT (malicious software as carrier), virus, Trojan horse, blackmail software and so on. Malicious programs can spread rapidly in industrial networks by means of selfreplication, active detection and automatic transmission, which can cause network delay, host failure, business fluctuation, even physical damage, business shutdown and other serious consequences, and pose a great threat to safety production of metallurgical industry enterprises.

Key words: ICS; Network security technology; Network virus
