Who should own cyber resilience planning across agencies and critical infrastructure?

cyber resilience planning should be owned as a shared business and operational responsibility, not left to the security team alone. The right owner is the leader accountable for continuity of the service or mission, with security, infrastructure, and operations leaders contributing the controls, recovery plans, and testing needed to make resilience real.

Why Shared Ownership Is the Right Model

Cyber resilience spans prevention, response, recovery, and service continuity, so ownership has to match the business service being protected. When an outage affects public services, safety, or essential operations, the accountable owner needs authority over priorities, dependencies, and recovery trade-offs, while technical teams handle the mechanisms that keep systems available and recoverable.

In practice, that means executive leadership owns the risk decision, infrastructure owners own recovery of the platform, and security teams own the assurance that controls such as segmentation, backup integrity, and incident readiness are in place. The CISA Industrial Control Systems resources are a useful reminder that resilience in critical environments depends on operating context, not just generic IT controls.

Shared ownership also prevents a common failure mode where resilience is treated as an IT project with no clear service owner. That approach tends to produce plans that exist on paper but fail under stress because no one is accountable for downtime tolerances, recovery sequencing, or the operational impact of degraded service.

What Ownership Should Cover in Practice

Resilience ownership should include the full lifecycle of preparation, testing, and recovery, not just incident response. That means deciding which services are mission critical, what recovery time and recovery point targets are acceptable, which dependencies must be mapped, and which manual workarounds exist if technology is unavailable.

For agencies and infrastructure operators, the best pattern is a joint operating model: business or mission leaders set tolerance for disruption, operational leaders define continuity procedures, and technical teams implement backup, failover, restoration, and monitoring. This becomes especially important when external dependencies, suppliers, or sector-wide platforms can create correlated failure across many organisations.

Because critical infrastructure faces active threat pressure, resilience planning should be informed by real adversary and outage patterns. The ENISA Threat Landscape helps frame the threat side of that planning, while the CISA cyber threat advisories show why continuity planning must assume ransomware, service disruption, and operational interference rather than isolated technical faults.

Where control failures involve known exploitable weaknesses, planning should also include rapid containment and restoration paths. The CISA Known Exploited Vulnerabilities Catalog is relevant because resilience owners need to know which weaknesses can turn a recoverable event into a prolonged outage.

How to Assign Accountability Without Losing Technical Control

Accountability should sit with the leader who can make continuity decisions, usually a mission owner, operations executive, or agency leader with service responsibility. Security does not own the business outcome, but it does own the assurance that recovery assumptions are tested, access paths are constrained, and incident playbooks are executable.

The cleanest governance model is to separate decision authority from implementation responsibility. Executives approve risk tolerance and outage priorities; infrastructure and security teams implement the controls; and operational leaders validate that the recovery process works under realistic conditions. That distinction matters because resilience often requires trade-offs, such as whether to restore service quickly from a clean but older backup or spend more time rebuilding a tighter, more trusted environment.

For organisations that depend on cloud or managed services, resilience ownership should extend to third-party dependencies and platform assumptions. The CSA Cloud Controls Matrix is useful here because it ties resilience-adjacent concerns to cloud governance, access management, and operational controls that often sit outside a single team’s direct control.

Practitioner Guidance

What to verify: Confirm that every critical service has a named business owner, a technical owner, a tested recovery objective, and a documented dependency map. If any one of those is missing, resilience is still an aspiration rather than an owned capability.

Decision rule: If the service outage would disrupt public safety, statutory obligations, or mission delivery, ownership should sit above the security function and include operational leadership with authority to prioritise recovery.

What good looks like: The organisation can explain who decides, who executes, and who accepts residual risk during an outage, and those roles are exercised in exercises rather than only in policy documents.

Practitioner takeaway: Cyber resilience fails when everyone is responsible in theory but no one is accountable in practice. Ownership should follow the service outcome, with security as an enabling control function and leadership as the decision point for continuity risk.
