Healthcare Cybersecurity

Patient safety first

Security priorities should reflect clinical and operational consequences, not only technical severity. Loss of availability or integrity can be as important as loss of confidentiality.

Core practices

• Govern critical assets and assign accountable owners.
• Use strong identity, access, email, endpoint, network, and vulnerability controls.
• Protect backups and test restoration.
• Prepare downtime communications and approved manual workflows.

A shared responsibility

Leadership, clinical operations, IT, security, facilities, vendors, and communications each hold part of the response.

A consequence-led risk model

• Begin with services whose loss, delay, or corruption can affect patient safety.
• Trace each service to identities, applications, devices, interfaces, facilities, utilities, staff, and suppliers.
• Assess confidentiality, integrity, and availability separately; the same system can have different consequences for each.
• Record assumptions, compensating safeguards, accountable owners, and review triggers.

Layered defensive outcomes

• Govern: leadership sets risk tolerance, authority, ownership, and funding.
• Identify: teams maintain service, asset, dependency, data-flow, and vendor knowledge.
• Protect: access, configuration, segmentation, updates, backups, and workforce practices reduce exposure.
• Detect: security and operational monitoring reveal abnormal access, data behavior, and service degradation.
• Respond and recover: command, downtime, communications, evidence, restoration, and reconciliation work as one system.

Measures that matter

Combine technical measures such as privileged-access review, patch exposure, alert coverage, and restore success with operational measures such as downtime activation time, offline supply readiness, exercise findings, service restoration time, and unresolved reconciliation items. A control count alone does not demonstrate resilience.

A practical improvement cycle

Select a small number of high-consequence services, document a current-state profile, choose prioritized HHS and NIST outcomes, assign owners, test evidence, exercise downtime, and repeat. Exceptions should state the risk, compensating safeguard, approving role, expiration, and next review.
