Industrial Control Systems

Critical infrastructure (CI) across all sectors depend on control systems for safe and efficient operation. Advancing the security and resilience of industrial control systems (ICS) is one of CISA’s top priorities. As the lead federal agency responsible for helping CI partners manage ICS security risk, we partner with government and industry to deploy the technologies and practices that will guard critical infrastructure from the threats of today, while building innovative capabilities to defend against emerging threats on the horizon.

The security of industrial control systems is among the most important aspects of our collective effort to defend cyberspace. As ever, CISA remains committed to working with the industrial control systems (ICS) community to address both urgent operational cyber events and long-term ICS risk. While the ICS risk landscape evolves, this truth remains: the only way the nation can permanently shift the cybersecurity advantage to ICS cyber defenders is through collective action.

CISA’s efforts to reduce cyber risk to control systems center around four core priorities.

1. We must defend ICS environments against the most urgent threats.
2. Find and defeat adversaries before they cause harm. CISA and its partners will work together to improve visibility in OT environments so that we identify and defeat malicious activity quickly before it causes wide-spread harm.
3. We must equip critical infrastructure owners and operators and cyber defenders with the technologies and tools required to dramatically raise adversary time, costs, and technical barriers.
4. Finally, we must sustain operational resilience by addressing systemic weaknesses to better enable control systems to withstand cyber incidents with minimal impact to critical infrastructure.
