城市供排水工控系统分析与“1+4”多重工控信息安全防护应用

Analysis of Industrial Control System(ICS)of Urban W ater Supply and Drainage and the Application of ICS"1+4"Security Protection

随着国家信息化建设的推进,城市供排水系统数字化、信息化水平不断提高,其原来封闭的网络环境也逐步开放,带来了一定的信息安全问题,严重影响城市用水。城市供排水系统中原水、供水、排水及管网工控系统缺少安全设计,导致系统抵御外界网络攻击的能力不足。工控系统"1+4"多重工控信息安全防护体系实现城市供排水工控网络安全可知、可视、可管、可控,有效提升城市供排水工控网络安全水平。

With the advancem ent of national inform atization,the level of digitalization and informatization of urban water supply and drainage systems has been continuously improved,and the closed network environm ent is gradually opening up,which brings some information security problems and seriously affect urban water.The lack of safety design of the industrial control system of raw water,water supply,drainage and pipe network in urban water supply and drainage system leads to the lack of the ability of the system to resist external netw ork attacks.The"1+4"m ultiple industrial control information security protection system of industrial control system realizes the knowable,visible,manageable and controllable security of urban water supply and drainage industrial control network,and effectively improves the security level of urban w ater supply and drainage industrial control network.
