OT security protects industrial control systems and operational environments from cyber threats without disrupting critical processes. It involves risk assessments, ICS and SCADA security reviews, network segmentation, secure remote access, and continuous monitoring strategies. By aligning with standards such as IEC 62443 and NIST, organizations can reduce operational risks, improve resilience, and protect critical infrastructure.
Systems must run continuously without interruption.
Many OT systems use older hardware and software that cannot be easily patched or replaced.
Industrial equipment often operates for 10–20 years or more.
Systems control physical processes that require precise timing.
Failures can impact human safety and the environment.
Evaluate industrial systems to identify vulnerabilities, threats, and potential operational impacts.
Assess control systems, controllers, and industrial software for security weaknesses and misconfigurations.
Separate IT and OT networks to prevent attackers from moving between business and industrial systems.
Implement controlled and monitored remote connections using authentication, jump servers, and session monitoring.
Monitor OT networks for abnormal behavior or cyber threats using tools designed for industrial protocols.
Identify and maintain an accurate inventory of all devices and systems within the OT environment.
