Reduce, Replace, Recover: Three Cybersecurity Priorities for Critical Infrastructure

Cybersecurity is no longer only an IT concern. For organizations that own, operate, or support critical infrastructure, it is closely connected to the ability to keep essential systems and services running.

Power, water, communications, transportation, healthcare, and other critical services increasingly depend on connected technologies. That connectivity creates opportunity, but it also makes cybersecurity preparation increasingly important. CISA emphasizes that organizations supporting critical infrastructure play an important role in protecting the services communities depend on.

Cybersecurity is ultimately about protecting more than technology. It is about protecting operations, services, and the people who depend on them.

During Cybersecurity Awareness Month, CISA is highlighting three straightforward priorities for critical infrastructure owners and operators: Reduce, Replace, Recover.

Reduce Vulnerabilities

Every connected system can introduce potential risk, and not every vulnerability carries the same level of urgency.

Organizations should understand where their greatest exposures exist and focus attention on vulnerabilities that could create the most significant consequences for their systems and operations.

CISA provides additional guidance on prioritizing security updates based on risk.

Reducing cyber risk starts with knowing where your organization is most exposed.

Replace End-of-Support Technology

Technology that reaches the end of vendor support can become increasingly difficult to protect. Without ongoing security updates, vulnerabilities may remain unresolved and create unnecessary exposure.

Keeping an inventory of devices and systems, and planning for their replacement before support ends, can help organizations stay ahead of these risks rather than reacting to them later.

Technology lifecycle planning is also cybersecurity planning.

Recover and Keep Operations Moving

Cybersecurity cannot be built around prevention alone.

Organizations also need to consider what happens when systems are disrupted. Recovery planning helps teams prepare to restore critical functions, protect essential services, and continue operating when normal systems or communications are unavailable.

CISA's CI Fortify resources offer guidance focused on strengthening the ability of critical infrastructure organizations to withstand and recover from disruption.

A strong cybersecurity strategy does not only ask, “How do we prevent an incident?” It also asks, “How will we continue operating if one happens?”

Cybersecurity Is an Ongoing Responsibility

Cybersecurity Awareness Month gives organizations an opportunity to revisit their preparedness, but cyber resilience requires attention throughout the year.

Reduce the vulnerabilities that create unnecessary exposure. Replace technology that can no longer be adequately protected. Recover with plans that help critical operations continue when disruption occurs.

The goal is not to eliminate every possible cyber risk. It is to better understand risk, make informed decisions, and strengthen the organization's ability to respond when circumstances change.

For critical infrastructure organizations in particular, that preparation matters because the systems being protected often support services that extend far beyond the organization itself.

Cybersecurity awareness is the starting point. Resilience comes from what organizations do with that awareness.
