OT versus IT security


OT (Operational Technology) security and IT (Information Technology) security are two distinct areas of cybersecurity that have unique challenges, objectives, and priorities.

OT security focuses on securing industrial control systems (ICS), including supervisory control and data acquisition (SCADA) systems, power plants, manufacturing facilities, and other critical infrastructure. OT systems are designed to control and monitor physical processes, such as the flow of water, oil and gas pipelines, and electrical grids. The focus of OT security is to maintain the safety, security, and reliability of these critical systems. Unlike IT security, where confidentiality and data integrity are the primary goals, OT security focuses on ensuring the safety and reliability of these systems to prevent physical harm to people, equipment, and the environment.

IT security, on the other hand, is concerned with securing computer networks, devices, and data within organizations, including personal identifiable information (PII), financial data, and business information. The central focus of IT security is to maintain the confidentiality, integrity, and availability of digital information.

Overall, while both OT security and IT security require cybersecurity measures, the objectives, priorities, and challenges differ significantly. Successful cybersecurity programs for OT and IT systems require a combination of technical expertise, industry knowledge, and understanding the unique requirements of each type of system.
