Executive Summary
A new study from Black Book Research indicates a fundamental shift in how European hospital leaders perceive cybersecurity threats. The risk has evolved from being primarily about data theft and privacy breaches to a direct and immediate threat to patient care delivery and safety. The Pre-HIMSS26 Europe Copenhagen Cybersecurity Demand Pulse Survey found that an overwhelming 82% of 284 hospital executives rate their concern about cyberattacks as "very high or extreme." This heightened awareness is reshaping cybersecurity investment priorities, moving from basic prevention to ensuring clinical and operational resilience during and after an attack.
Regulatory Details
The survey highlights a critical disconnect between perceived risk and operational readiness. While 74% of hospital leaders believe a major cyber event is likely this year, their confidence in safely managing patient care during extended downtime is alarmingly low.
- 59% of hospitals believe they can operate safely for up to 24 hours without access to their core Electronic Health Record (EHR) systems.
- This confidence drops to a mere 14% when the outage extends to 72 hours.
This "resilience gap" is the central finding of the report. It suggests that while awareness of the threat is high, the practical ability to withstand a prolonged cyberattack, such as a ransomware incident that locks up critical systems for days or weeks, is severely lacking. This has profound implications for patient safety, as disruptions to medication administration, lab result access, and surgical planning can have life-threatening consequences.
Affected Organizations
The study's findings are applicable to hospitals and health systems across Europe. The report notes that attackers are specifically targeting the unique pressures of this sector, which include:
- Nationally Connected Health Networks: Interconnectivity increases the potential for an attack to spread rapidly across a region or country.
- Aging Infrastructure: Many hospitals operate on a mix of modern and legacy IT systems, creating a complex and difficult-to-defend attack surface.
- Accelerated Cloud Migration: While beneficial, rapid migration to the cloud without adequate security controls can introduce new vulnerabilities.
Compliance Requirements
In response to this shifting threat landscape, the survey reveals a change in cybersecurity spending priorities. Hospitals are moving beyond basic compliance and breach prevention to focus on technologies and strategies that support clinical continuity. Key investment areas now include:
- Identity Resilience: Protecting and quickly restoring access to clinical identities.
- Ransomware Recovery: Solutions that enable rapid, reliable recovery from ransomware attacks.
- Immutable Backups: Ensuring that backup data cannot be altered or deleted by attackers, a key defense against double-extortion ransomware. This is a form of Data Backup.
- Read-Only Clinical Access: Systems that provide clinicians with read-only access to patient data during downtime, allowing for safer care delivery even when the primary EHR is offline.
Impact Assessment
The direct impact of a cyberattack on patient care cannot be overstated. When EHRs, imaging systems (PACS), and lab information systems (LIS) are unavailable, hospitals are forced to revert to manual, paper-based processes. This leads to:
- Medical Errors: Increased risk of medication errors, incorrect diagnoses, and treatment delays.
- Cancelled Procedures: Postponement of elective and even urgent surgeries and appointments.
- Patient Diversion: Ambulances are diverted to other hospitals, overwhelming the entire regional healthcare system.
- Prolonged Hospital Stays: Inefficient paper processes can lead to longer patient stays, increasing costs and risks of hospital-acquired infections.
The study confirms that the primary damage from a modern healthcare cyberattack is not the stolen data, but the disruption to the core mission of providing care.
Compliance Guidance
Based on the study's findings, hospital boards and health technology leaders should take the following actions:
- Prioritize Operational Resilience: Shift the focus of cybersecurity strategy from solely preventing breaches to ensuring the hospital can function safely during a breach. This involves robust incident response and business continuity planning that is regularly tested with clinical staff.
- Invest in Downtime Solutions: Implement technologies that support clinical operations during an outage, such as read-only EHR access and reliable communication platforms.
- Secure Backups: Validate that backup systems are segmented from the primary network and are immutable. Regularly test the ability to restore critical systems within a clinically acceptable timeframe. This aligns with Decoy Object (D3-DO) principles if honeypot backups are used.
- Conduct Realistic Drills: Run simulation exercises that model a 72-hour+ outage. These drills should involve not just IT staff, but nurses, doctors, and administrators, to identify and address gaps in paper-based procedures.

Data Backup
Implement and regularly test a comprehensive data backup and recovery plan. Backups should be immutable and stored offline or on a segmented network.
Privileged Account Management
Restrict administrative privileges and segment networks to limit the blast radius of a ransomware attack.

D3FEND Defensive Countermeasures
Given the study's finding that only 14% of hospitals are confident in operating after a 72-hour outage, a robust and tested Data Backup strategy is paramount. Hospitals must move beyond simple nightly backups. They should implement the 3-2-1 backup rule: three copies of data, on two different media types, with one copy off-site. For ransomware resilience, this 'off-site' copy must be either offline (air-gapped) or immutable (write-once, read-many). This prevents attackers who gain network access from deleting or encrypting the backups. Most importantly, recovery procedures must be tested quarterly, at minimum. This includes not just restoring data, but restoring entire critical systems like the EHR, PACS, and LIS in a test environment to validate RTOs (Recovery Time Objectives). The goal is to be able to restore service within the 24-hour window where clinical confidence remains high, directly addressing the resilience gap identified in the Black Book report.
To counter the threat of attacks spreading across nationally connected health networks and aging infrastructure, hospitals must prioritize Network Isolation and segmentation. This involves dividing the hospital's network into smaller, isolated zones. For example, critical medical devices (like infusion pumps and MRI machines) should be on a separate network segment from the general corporate IT network (used for email and web browsing). The EHR system should reside in its own protected enclave. Access between these segments should be controlled by strict firewall rules, following a principle of least privilege. This 'zero-trust' approach contains the damage from a breach. If a phishing attack compromises a workstation on the corporate network, segmentation prevents the attacker from easily moving laterally to the medical device network or the EHR servers. This directly mitigates the risk of an IT incident becoming a patient care crisis, which is the core concern highlighted by the European hospital leaders.
The study's most alarming statistic is the collapse in operational confidence after 24 hours. This points to a failure in Downtime Planning. IT and clinical leadership must collaborate to create and drill comprehensive downtime procedures. This goes beyond IT's disaster recovery plan. It must include clinical workflows: How will nurses document medication administration on paper? How will the lab communicate critical results to the emergency department? How will surgeons access pre-op imaging? These paper-based workflows must be printed and stored in physical 'downtime kits' on every ward. Furthermore, hospitals should invest in 'read-only' downtime viewers. These are simple, secure appliances that hold a recent, read-only copy of the EHR. During an attack, clinicians can use these viewers to safely access patient histories, allergies, and medication lists, drastically reducing the risk of medical errors that occur when working from incomplete paper records. Regular, unannounced downtime drills are essential to ensure staff are prepared and plans are effective.
