Özet:

Developing technology leads to innovations in the field of industry, while information technology started Industrial 4, which is called Industrial Revolution. The biggest problem of Industry 4, which is rapidly integrating into mechanical production lines, is the cyber-attacks that threaten the information integrity. Smart Factory period has started with the transfer of control technology of Information technology which makes life easier to the chemical production processes. In smart factories, devices, systems, robots and all the objects in the network are communicated with each other by a certain protocol and carried out by the concept of Internet of Objects or Systems. Particularly in smart factories, it is inevitable to experience catastrophic accident by the operating parameters go out of control, as well as economic impacts by cyber-attacks. The healthy establishment of the security management of Smart Factories requires proper planning of the "Safety Instrumented System" design done next to the process design. This design can be carried out with remote secure access considering all possible risk combinations, and the establishment of accessing to system in when logical decisions can be necessary in complex situations.
