OT cybersecurity safeguards operational technology (OT) systems, including industrial control systems (ICS) and supervisory control and data acquisition (SCADA) systems, from cyber threats. These systems are crucial for managing critical infrastructure like power plants, water treatment facilities, and manufacturing plants. OT cybersecurity involves implementing measures such as network segmentation, access controls, encryption, and intrusion detection to protect OT assets from unauthorized access, manipulation, or disruption.
