🛡️Critical Infrastructure Protected by Shared Command🛡️
💡 Imagined Endstate:
Imagine a homeland response system where a cyberattack on power, water, ports, hospitals, communications, or military support infrastructure does not leave local responders improvising alone and private-sector operators can see the same operating picture, exchange the right information, and move together before disruption turns into cascading failure.

O’Donohue, D. (2026, April 24). Why cyber threats to critical infrastructure demand a new homeland response model. Homeland Security Today. link.
💥 What’s the Big Deal:
Imagine a future where homeland cyber response works like a practiced emergency network, not a last-minute conference call🔦. Critical infrastructure defense cannot stop at the firewall. It has to extend into emergency management, civil support, intelligence sharing, mobile coordination, and public accountability. When cyberattacks can reach the water pump, the hospital generator, the port gate, or the base power line, the response model must be built for the real world, not just the server room.
The article opens with a disaster that was not cyber at all: the July 2025 central Texas flash flooding, where volunteers and local authorities used CIVTAK, a civilian version of the military’s Technical Awareness Kit, to coordinate search operations across more than 60 miles. People used mobile devices to check in, navigate, share maps, and maintain accountability during a chaotic response🌐. That example matters because it shows what modern response now requires: not just courage on the ground, but a shared command-and-control picture when the situation is moving faster than the paperwork.
O’Donohue’s warning is that cyberattacks on critical infrastructure would demand the same kind of coordination, but at a much larger and more complex scale🏗️. The threat is not theoretical. The article notes that nation-state cyber actors such as Salt Typhoon, Volt Typhoon, and CARR have already infiltrated U.S. power and water infrastructure, creating risk for communities far beyond the technical teams that manage networks.
The big deal is that cyber is no longer just an IT department problem💻. If power, water, ports, telecommunications, medical support, fuel systems, or satellite ground stations are disrupted, the consequences become physical fast. The attack may begin in code, but people experience it as darkness, delay, confusion, and loss of confidence.
That is why the missing piece is command and coordination📡. O’Donohue argues that the United States lacks a robust C2 plan that can connect during a critical infrastructure cyber incident. State and local partners may stop many cyber threats, but nation-state-level threats require a response model that can move intelligence, authority, technical support, and operational decisions across many layers of government.
The article’s three-part answer is useful because it is not just “buy more cyber tools”. It calls for resilience, information exchange, and mobile C2🧰. Resilience means preparing systems to withstand attack, not simply checking compliance boxes. Information exchange means building ways to share sensitive intelligence with responders who may not normally hold federal clearances. Mobile C2 means using the devices people already carry, so coordination does not depend on perfect conditions or fixed command posts.
For the Pacific, this is especially urgent🌺. Island systems are tightly connected and geographically constrained. A disruption to power, water, ports, undersea cables, airports, hospitals, fuel, or military support can ripple quickly across daily life. In Hawaiʻi, Guam, CNMI, Palau, and other Pacific jurisdictions, cyber resilience is also disaster resilience. If the systems that support response are disrupted, the community may have to manage both the incident and the failure of the tools needed to respond.
