工业控制系统信息管理和网络组建DCS安全防护就是工业控制系统信息管理和网络组建安全域,工业控制系统信息管理和网络组建安全域的概念是指同一系统内有相同的工业控制系统信息管理和网络组建安全保护需求,相互信任,并具有相同的工业控制系统信息管理和网络组建安全访问控制和边界控制策略的网络或系统。数据允许从低工业控制系统信息管理和网络组建安全等级的域流入高工业控制系统信息管理和网络组建安全等级域,反之,则受严格控制。从而保证用户网络内的数据工业控制系统信息管理和网络组建安全。
Industrial control system information management and network construction DCS security protection is the industrial control system information management and network security domain, industrial control system information management and network security domain concept is the same system with the same industrial control system information management and network Establish a network or system that needs security protection, mutual trust, and has the same information management of industrial control systems and network security access control and border control policies. Data allows the flow of information from highly-industrial control systems to information-management and network-based security levels from low-MI systems to information-management and network-organized security levels, and conversely, it is tightly controlled. So as to ensure the user’s network data industrial control system information management and network security.
