Critical Infrastructure Operators Urged to Fortify Against Nation-State Attacks
Published on May 5, 2026, the Cybersecurity and Infrastructure Security Agency (CISA) has initiated a significant campaign aimed at enhancing the nation’s resilience against major cyber threats targeting critical infrastructure sectors. This new program, dubbed "CI Fortify," serves as both a warning and a guidance tool for operators, stressing the necessity to disconnect operational technology (OT) networks from business networks and prepare robust backup systems to counteract the potential corruption of vital files.
CISA’s Acting Director, Nick Andersen, highlighted the urgency of this initiative during a recent media briefing, positioning it as a foundational call-to-action for infrastructure providers nationwide. The plan advocates for a resilience model, allowing organizations to continue their essential service delivery in scenarios of network degradation, disrupted communications, or compromised core systems.
The CI Fortify framework emphasizes two essential capabilities: isolation and recovery. The concept of isolation focuses on severing the connections to third-party dependencies, such as cloud service providers, vendors, and telecommunications services. This strategy also serves to cut off adversarial command-and-control pathways, thereby limiting the enemy’s ability to manipulate or disrupt infrastructure systems.
Recovery, on the other hand, pertains to the restoration of vital systems while maintaining isolation. This includes leveraging pre-tested backup procedures, ensuring offline capabilities, and creating avenues for manual operations—essentially allowing operators to continue functioning effectively, even when faced with cybersecurity challenges. CISA underscores the importance of regular testing and exercises to confirm these capabilities, urging operators to validate their preparedness before a crisis arises.
As the backdrop for this initiative, federal cyber officials have expressed growing concern that foreign adversaries are already embedded within the nation’s critical infrastructure. Andersen articulated the gravity of the situation, indicating that nation-state actors aim to infiltrate infrastructure systems to disrupt essential services such as water, electricity, and communications. This context amplifies the importance of the CI Fortify initiative in safeguarding against potential threats.
CISA has begun conducting pilot assessments in collaboration with various infrastructure operators, intending to adapt its approach based on specific risks and operational requirements relevant to each sector. However, Andersen refrained from disclosing which particular organizations would be the first to engage with the agency on this initiative, leaving many in the industry eager for more specifics.
To support the extensive goals of CI Fortify, CISA has announced plans to significantly bolster its workforce, targeting the recruitment of over 300 additional personnel. The focus will be on increasing regional field operations and enhancing technical expertise related to industrial control systems and operational technology. This expanded regional presence is critical for assessing infrastructure operators and supporting effective implementation of the CI Fortify framework across ten regions recognized by the Federal Emergency Management Agency (FEMA).
Moreover, the initiative will require coordination with other federal agencies and sector partners, particularly as smaller operators may struggle to implement the necessary isolation and recovery measures independently. This collaborative effort aims to foster a more unified approach toward infrastructure security, facilitating a more robust defense against cyber threats.
Despite the important strides being made with CI Fortify, CISA continues to face challenges stemming from leadership instability and resource limitations. Concerns have been raised regarding the agency’s ability to adequately support its partners on a larger scale, especially given the recent prolonged funding lapses that have forced CISA into a more reactive stance. These constraints have historically limited proactive services, including vulnerability scanning and stakeholder engagement efforts.
In summary, the CI Fortify initiative represents a pivotal shift in how the United States approaches cybersecurity within its critical infrastructure sectors. By advocating for isolation and recovery strategies, CISA is not only urging operators to take precautionary measures but is also preparing them to maintain essential services through potential crises. As the threat landscape continues to evolve, the focus on resilience and proactive security measures will be crucial to safeguarding the nation’s vital systems against increasingly sophisticated cyber threats.
