CISA wants critical infrastructure to operate ‘weeks to months’ in isolation during conflict

CyberScoop

May 5, 2026 at 9:47 PM

Overview

The Cybersecurity and Infrastructure Security Agency (CISA) is initiating assessments aimed at ensuring critical infrastructure can function independently for extended periods, ranging from weeks to months, particularly during conflicts. This strategy focuses on disconnecting operational technology (OT) networks from information technology (IT) systems and third-party vendors. The goal is to enhance resilience against potential cyber threats that could arise during times of crisis. By encouraging critical infrastructure entities to prepare for isolation, CISA is addressing vulnerabilities that could be exploited by adversaries looking to disrupt essential services. This initiative is crucial for maintaining public safety and service continuity during emergencies.

Key Takeaways

Affected Systems: Critical infrastructure systems, including energy, water, and transportation sectors.
Action Required: Implement measures to isolate OT networks from IT and third-party connections.
Timeline: Newly disclosed
