工控系统信息安全与加工网络防护方案研究

摘要

文章通过分析当前工控系统的信息安全问题，得到了加工网络与办公网络进行信息交换的需求，研究了加工网络中的安全风险，给出了加工网络信息安全防护方案。该方案对数控加工网络边界隔离设备和数控系统终端防护设备的功能进行了详细的说明，并给出了这两款防护设备在数控加工网络中的部署方式。该方案的实施能够提高数控加工网络的信息安全等级，保障了数控加工信息安全。%The requirements of connection between numerical control network and ofifce network are given by analyzing the problem of information security in industrial control system. The security risks of numerical control network in military industry are studied, and the solution of information security for is this network proposed. In this solution the functions of security isolation equipment and the terminal security equipment for numerical control system are illustrated. The deployment way of these two equipments are also expressed. The implementation of the scheme would upgrade information security of numerical control network in military industry to insure its information security.
