The Concept of Information Security in the Process Control System

The specifics of ensuring information security of the automated process control system consist in the fact that such systems interact with the processes of the physical world and their primary feature is to protect people and the environment from technological risks. The information security of an automated process control system is important because vulnerabilities can be used just for a physical attack of people, environment and tangible assets. Given the above, the provision and evaluation of information and functional safety of an automated process control system should be coordinated within a single life cycle (Safety & Security Life Cycle). This article systematizes the requirements for information security and functional safety of the process control system.
