对于工业控制系统的安全而言,我们关注的焦点不应只是在网络安全(Security),保证信息本身的机密性和完整性,更为重要的是要关注工控系统安全问题可能对被控设备、乃至整个生产系统的破坏(本质安全),关注工控系统自身的防危性(Safety)。工业控制系统缺乏本质安全通过对相关的案例进行分析以后,我们发现工业控制系统在几大方面都存在着弱性。一般信息系统的安全架构强调信息的保密性、完整性和可用性,普遍采用:防火墙在网络边界提供访问
For the safety of industrial control systems, our focus should not only be on the network security (Security), to ensure the confidentiality and integrity of the information itself, more importantly, we must pay attention to industrial control system security issues may be accused of equipment, As well as the destruction of the entire production system (intrinsic safety), concerned about the industrial system’s own safety (Safety). Lack of Intrinsic Safety in Industrial Control Systems After analyzing the relevant cases, we found that there are several weaknesses in industrial control systems. The security architecture of a general information system emphasizes the confidentiality, integrity and availability of information and is commonly used: firewalls provide access at the network boundary
