2. Definition of Industrial Control Systems (ICS) Security
ICS security refers to the safeguarding of control systems and associated instrumentation used for industrial processes. These systems include Supervisory Control and Data Acquisition (SCADA) systems, Distributed Control Systems (DCS), and Programmable Logic Controllers (PLC). The primary objective of ICS security is to ensure the confidentiality, integrity, and availability of these systems, thereby preventing unauthorized access, data breaches, and operational disruptions.
The ICS security market has witnessed significant growth due to the escalating frequency of cyberattacks targeting critical infrastructure. According to Grand View Research, the global ICS security market was valued at USD 18.99 billion in 2023 and is projected to grow at a compound annual growth rate (CAGR) of 8.2% from 2024 to 2030.
The market encompasses a wide range of solutions and services designed to protect industrial control environments. These include network security, endpoint security, application security, and database security solutions, as well as consulting, integration, support, and maintenance services.
