November 2026 | Cybersecurity and Infrastructure Resilience
Hospitals need electricity and communications. Water utilities rely on operational equipment and skilled personnel. Transportation systems depend on technology, suppliers, and physical facilities. When one essential service fails, the effects can extend far beyond the organization that experienced the disruption. That interconnected reality is the focus of the Cybersecurity and Infrastructure Security Agency's (CISA) Critical Infrastructure Security and Resilience Month 2026.
Under the theme Resolve to be Resilient, CISA is encouraging organizations to understand what they depend on, focus on consequential risks, prepare workable plans, and measure whether they can respond and recover. The message is not that every disruption can be prevented. It is that organizations can make better decisions before an incident threatens essential services.
Key Takeaways
- November is CISA's annual Critical Infrastructure Security and Resilience Month.
- The 2026 campaign emphasizes four practices: understand systems and dependencies, prioritize risks, create actionable plans, and measure progress.
- Critical infrastructure resilience covers cyber threats, physical hazards, operational failures, and recovery capabilities.
- Organizations should test continuity and recovery arrangements rather than assuming a written plan will work.
- CISA offers a campaign toolkit and additional resources for operators, government partners, and communities.
What Critical Infrastructure Resilience Means
Critical infrastructure includes the assets, systems, and networks that support essential functions of everyday life. CISA describes a landscape of 16 critical infrastructure sectors within an interconnected ecosystem. Infrastructure security seeks to reduce the likelihood or impact of harmful events. Resilience goes further: it asks whether essential functions can continue, adapt, or recover when something does go wrong.
A resilient organization does not rely on a single firewall, backup, or emergency contact. It understands the combination of people, technology, buildings, suppliers, communications, and procedures required to deliver its most important services. It also knows which functions must be restored first and how to operate temporarily when normal systems are unavailable.
Consider a hypothetical water utility whose billing website becomes unavailable. That could be inconvenient, but a disruption to equipment monitoring or communications with operators may have more urgent operational consequences. A useful resilience program distinguishes between these situations instead of treating every system as equally critical.
Resilience is not only a cybersecurity concern. CISA's campaign also discusses physical threats, natural hazards, infrastructure reliability, and other causes of disruption. Organizations should examine how these risks interact rather than maintain disconnected plans for each department.
What CISA Announced for November 2026
CISA's 2026 campaign continues the theme Resolve to be Resilient. In its November 2 announcement, the agency highlighted the frontline operators who keep essential services functioning and described four recurring actions that can help organizations prepare for disruption. The campaign also includes a communications toolkit containing materials organizations can use to discuss resilience with their audiences.
The official materials place particular emphasis on practical preparation. Instead of focusing exclusively on abstract risk ratings, CISA encourages organizations to identify important assets and outside services, assess meaningful threats, create usable plans, and learn from exercises and incidents. These priorities are relevant to large infrastructure operators, local governments, suppliers, and smaller businesses that support essential services.
The campaign is an awareness and preparedness initiative. Its existence does not, by itself, establish a new cybersecurity regulation, a specific incident, or a universal technical requirement for every organization. Sector-specific obligations must be evaluated separately.
Priority 1: Know Your Infrastructure and Dependencies
The first step is understanding what actually keeps the organization running. A conventional inventory may list servers and applications, but a resilience inventory must also show the relationships among essential functions, staff, physical facilities, power, network connectivity, third-party providers, and specialized equipment.
Start with essential services
Identify the services whose interruption would create the greatest consequences for safety, public welfare, operations, or customers. For each service, record the systems and teams required to deliver it. Then identify the dependencies that sit outside direct organizational control.
For example, a hypothetical emergency communications provider may rely on electricity, carrier connectivity, cloud authentication, a building access system, and a limited number of trained administrators. If any one of those becomes unavailable, the provider needs to know whether it has an alternate route.
Look for hidden single points of failure
Shared identity platforms, remote access gateways, backup repositories, telecommunications circuits, and vendor-managed systems may support multiple services simultaneously. A dependency map helps reveal where one failure could cause several outages. It can also expose outdated documentation, unclear ownership, or assumptions about supplier recovery capabilities.
Practical exercise: Choose one essential service and draw its dependencies on a single page. Ask what would happen if the main network, primary facility, or most important supplier were unavailable for a day. Record which answers are confirmed and which require investigation.
Priority 2: Prioritize the Risks That Matter Most
Organizations rarely have unlimited budgets or personnel. CISA's guidance therefore emphasizes risk-based decisions. Rather than applying equal effort everywhere, leaders should consider which threats, vulnerabilities, and consequences could most seriously disrupt essential operations.
Risk prioritization requires more than a list of technical weaknesses. A high-severity software issue on an isolated test machine may pose a different operational concern from a moderate weakness in a system that controls a critical business process. Exposure, exploitability, compensating controls, and potential service consequences all matter.
Use a repeatable risk review
A practical review can ask: What could fail? How would that failure affect essential services? Which dependencies make the consequences worse? What controls already exist? Which actions would reduce risk most efficiently? The answers should inform decisions on maintenance, access control, supplier oversight, physical protection, and recovery investments.
For cybersecurity, organizations can review privileged access, unsupported systems, internet-exposed services, backup protection, network segmentation, and monitoring coverage. For physical resilience, they may assess facility access, alternate power, environmental hazards, and the availability of essential personnel. These are examples of areas to evaluate, not a claim that CISA mandated a single checklist for every operator.
Prioritization should be revisited when infrastructure changes, a major supplier changes, a new threat emerges, or an exercise reveals a weakness. A risk register that never influences operational decisions offers limited value.
Priority 3: Make Actionable Response and Recovery Plans
A resilience plan must work under pressure. It should explain who makes decisions, which services receive priority, how staff communicate, and what steps allow operations to continue when normal technology or facilities are unavailable. A lengthy document is not necessarily an effective plan.
Define acceptable downtime
Different services have different tolerance for interruption. Organizations should determine how long an essential function can be unavailable before consequences become unacceptable. They should also define the data and operational capabilities needed to restore that function safely.
These objectives help teams decide whether they need alternate equipment, redundant communications, manual procedures, offline documentation, or protected backups. Recovery targets should be realistic and validated through exercises, not selected only because they sound reassuring.
Prepare for degraded operations
CISA's toolkit emphasizes continuity and the ability to function in a degraded state. A practical plan might describe how employees verify instructions when email is unavailable, how operators reach emergency contacts when a network fails, and how a critical process can continue safely while a system is restored.
Cyber incident response and operational continuity should reinforce one another. A response team may need to isolate compromised equipment, while operational leaders must understand what that isolation means for essential services. These decisions should be coordinated before a crisis.
Exercise the plan
Tabletop exercises can test decision-making and communication. Technical recovery tests can reveal missing credentials, incompatible backups, unavailable replacement hardware, or undocumented dependencies. After each exercise, assign owners and deadlines to corrective actions. Rehearsal is valuable because it reveals problems while there is still time to fix them.
Priority 4: Measure Progress and Improve
The fourth CISA priority is to track progress and update plans using real lessons. Resilience cannot be judged only by whether a policy exists. Organizations need evidence that protective measures, recovery processes, and communications work as intended.
Useful measures might include the percentage of critical services with documented dependencies, the number of recovery procedures successfully tested, the age of unresolved high-priority findings, and the time required to restore a selected service during an exercise. These are suggested operational measures, not official CISA scoring criteria.
Metrics should support decisions rather than become a reporting exercise. If a recovery test takes longer than the agreed operational tolerance, leaders should investigate the cause, update the plan, and test again. If a supplier dependency remains unclear, the organization should establish an owner and obtain the missing information.
Progress also requires reviewing real disruptions, near misses, and changes in the environment. Lessons learned are most useful when they result in revised procedures, improved training, stronger technical controls, or better coordination with partners.
A Practical Critical Infrastructure Resilience Checklist
The following YARVICO checklist translates the campaign's four themes into a starting workflow. It is a general planning aid, not a regulatory compliance assessment.
- Identify essential functions: List the services whose interruption would have the greatest impact.
- Map dependencies: Document required systems, facilities, personnel, utilities, and vendors.
- Assign ownership: Name people responsible for each essential service and its recovery plan.
- Review cyber and physical exposure: Examine access, network connectivity, facility risks, and supplier dependencies.
- Prioritize corrective actions: Address weaknesses based on operational consequences and feasible risk reduction.
- Protect recovery capabilities: Review backup access, alternate communications, emergency contacts, and restoration procedures.
- Set recovery objectives: Define what must return first and how much interruption is acceptable.
- Test a realistic scenario: Exercise a loss of connectivity, facility access, or a key technology service.
- Record findings: Capture gaps, owners, target dates, and follow-up evidence.
- Repeat: Revisit assumptions after exercises, incidents, major upgrades, or supplier changes.
Example: A small infrastructure supplier might begin with a two-hour workshop involving operations, IT, management, and a vendor representative. The goal is not to solve every risk immediately. It is to agree on the most important service, its dependencies, the first likely failure scenarios, and a testable improvement plan.
What Different Organizations Can Do
Infrastructure owners and operators
Focus on operational consequences and continuity. Identify the systems that support essential functions, review critical supplier arrangements, test recovery procedures, and ensure technical teams and operational managers understand one another's priorities. CISA's toolkit also discusses modernization, secure-by-design principles, and scalable risk reduction.
Small businesses and technology suppliers
Smaller organizations may not operate a utility or transportation network, but they can still be important dependencies. A managed service provider, software vendor, equipment maintainer, or local logistics business may affect customers that provide essential services. Document service commitments, secure remote access, and clarify incident communication and recovery responsibilities.
Government and community partners
CISA encourages collaboration among industry and government stakeholders. Local officials can use the campaign to discuss regional dependencies, preparedness, public communication, and mutual assistance. Exercises involving several organizations may reveal coordination problems that a single organization's internal test would miss.
Students and cybersecurity professionals
Learning to defend critical infrastructure requires understanding operations as well as security technology. Students can practice dependency mapping, incident triage, network fundamentals, and recovery planning using fictional scenarios. Analysts should connect alerts and technical findings to business consequences, rather than treating every event as an isolated ticket.
Common Resilience Mistakes to Avoid
Confusing security with guaranteed availability: Strong prevention lowers risk but cannot eliminate all disruption. Recovery planning remains necessary.
Ignoring third parties: An organization may have excellent internal controls yet depend on a supplier with unclear continuity arrangements.
Writing plans that nobody tests: Contact lists become outdated, procedures fail, and critical assumptions go unchallenged when exercises are skipped.
Measuring activity instead of readiness: Counting completed meetings or documents does not show whether an essential service can be restored within an acceptable period.
Separating cyber and physical teams: A network outage, building problem, or cyber incident can have overlapping operational effects. Coordinated planning makes these dependencies easier to manage.

Conclusion: Make Resilience a Repeatable Practice
Critical Infrastructure Security and Resilience Month 2026 offers a straightforward lesson: preparation is strongest when organizations know what matters, understand what those services depend on, make decisions based on consequences, and test whether their plans work. The goal is not a perfect checklist. It is a repeatable process that reduces avoidable disruption and improves the ability to respond and recover.
For YARVICO readers, a practical first step is to select one essential service this week, document its dependencies, identify one high-consequence failure scenario, and schedule a short exercise. That modest starting point can produce more useful insight than an ambitious plan that never leaves the page.
