Security protection of industrial control systems needs to consider every detail.From on-site I/O devices,controllers,to the computer operating system of the operation station,there are both an industrial control network that guarantees the industrial system and an office network that guarantees production and operation in the industrial control network.Considering the security and fault tolerance of different business terminals Depending on the level,defense strategies and safeguards should be classified according to levels,and implementing a hierarchical defense-in-depth architecture requires different corresponding means to build a three-dimensional defense system from the whole to the details.

工业控制系统的安全防护需要考虑每一个细节。从现场I/O设备、控制器，到操作站的计算机操作系统，工业控制网络中同时存在保障工业系统的工业控制网络和保障生产经营的办公网络，考虑到不同业务终端的安全性与故障容忍程度的不同，防御策略和保障措施应该按照等级进行划分，而实施分层次的纵深防御架构需要分别采取不同的对应手段，构筑从整体到细节的立体防御体系。
