Особенности модели безопасности промышленной системы управления

Abstract

The article examines the characteristics and functions of the automated process management system (ASU TP) in the format of ensuring its information security. The differences in information security between TP ASU and traditional IT systems are shown. Because of the importance of the time component, the high reliability, high availability and high security of the industrial management network, the differences between the security functions of the ASU TP and IT systems are presented as follows: functional requirements are more important in the IT environment in terms of risk, but the ASU TP is focused on the manufacturing process, and accessibility is considered to be the highest requirement and requires that production be sustainable; Resource requirements - the real-time ASU TP operating system is often limited by resources, and computational resources may not be available to update the security features of these systems in the ASU TP components; security implications - Unlike conventional IT systems, the loss of information in the ASU TP can damage the production process. In general, the security of the industrial management system can be divided into three areas: functional security to ensure the safety functions of equipment and enterprise, physical security is designed to reduce harm from physical factors and information security - preventing illegal or malicious intrusion into the industrial management system or interfering in the planned work. The article identifies the type of safety of the ASU TP and presents the structural model of the industrial management system, as well as the management scheme and components of the TP ASU.
