首先,来看看因特网技术在工业上应用隐含的安全性问题,我们考虑管理一个从工厂层到顶层的信息系统。因特网使用的数据传输方式设计为主要在相对低优先权的应用中传输文本报文。对传统的办公室应用不要求根本上的改进。然而,新型的因特网用于分散的数据传输需要更高和完善的安全性。安全应用包括:远程监控、诊断、控制和维护;生产和管理中全集成的计算机系统(这样也产生了新的弱点);以
First, let’s take a look at the implications of the industrial application of Internet technology for security. Let’s consider managing an information system from the factory level to the top level. The data transmission methods used by the Internet are designed to transmit text messages primarily in relatively low priority applications. The traditional office applications do not require fundamental improvements. However, the new Internet requires more and better security for decentralized data transmission. Security applications include: remote monitoring, diagnostics, control and maintenance; fully integrated computer systems in production and management (this also creates new weaknesses);
