Ransomware Readiness at a Regional Hospital

Prioritize by patient safety, likelihood of exploitation, and inability to recover. First, close the identity gap: enforce MFA for remote EHR access and all privileged accounts, and remove standing privileged access where possible. Ransomware actors routinely use stolen credentials and remote access, and the hospital currently has no strong barrier on the paths most likely to be used. Second, create a segmented zone for medical devices and critical clinical systems, starting with the highest-risk devices and the EHR. A flat network lets an infection spread from an endpoint to infusion pumps and imaging, so segmentation directly reduces patient safety impact. Third, establish offline or immutable backups and test restoration, because the domain-joined online replica can be encrypted along with production.

Fourth, update the incident response plan with a 72-hour regulatory notification decision tree and downtime procedures. The €1.8 million investment should not wait, but the 90-day actions can reduce immediate risk while the capital project is approved. Antivirus and a firewall are baseline controls, not sufficient protection against ransomware. Document the prioritization rationale and residual risk.

The existing controls do not reduce risk enough to justify deferral. Antivirus and a firewall are preventive basics, but they do not stop credential-based intrusion, lateral movement on a flat network, or encryption of online backups. MFA for email only leaves remote EHR and privileged access exposed, which are high-value entry points. The online, domain-joined backup replica is not a compensating control for ransomware because it shares the same trust domain and can be deleted or encrypted.

The tabletop estimate of 36 hours of EHR downtime is itself evidence of unacceptable impact: diversion of emergency patients, delayed care, and regulatory exposure. Compensating controls should be judged on whether they materially reduce likelihood or impact and whether they are tested. Here, they reduce neither enough. Deferral would leave the hospital exposed through another capital cycle. A better approach is to approve interim measures, such as MFA rollout, backup isolation, and prioritized segmentation, while funding the full program. The board should accept residual risk explicitly only if it understands the patient-safety consequences. Internal audit should report the gap as high severity.

Use a calm, risk-based message anchored in patient safety and regulatory obligations, not alarmist language. Start with what the board needs to decide: whether to fund the €1.8 million program now or accept a documented residual risk through the next capital cycle. Explain the attack path in plain terms: a compromised endpoint or stolen credential can move across a flat network to clinical devices, and online backups may not be recoverable. Cite the tabletop result of 36 hours of EHR downtime and the 72-hour notification requirement as concrete consequences.

Avoid blaming the CIO. Acknowledge that antivirus and firewalls are necessary but insufficient, and present a phased roadmap with 90-day interim actions and a funded capital plan. State what internal audit can and cannot conclude in four weeks: we can validate the gaps and test selected controls, but we cannot certify the environment as secure. Give the board three options with risk trade-offs: fund now, fund partially with explicit risk acceptance, or defer with a documented escalation to the risk committee. Recommend the first and provide a reporting cadence so urgency is maintained without panic.
