On November 21, 2025, Bern University Hospital in Switzerland undertook a notable cybersecurity exercise, deliberately disconnecting its systems from the internet. this wasn’t a response to an active attack, but a planned simulation designed to test its resilience and preparedness against increasingly sophisticated cyber threats. The move underscores a growing trend among critical infrastructure organizations – especially healthcare providers – to proactively assess and strengthen their defenses.
Why Hospitals Are prime Targets
Hospitals are particularly vulnerable to cyberattacks due to the sensitive nature of the data they hold – protected health data (PHI) - and the critical, time-sensitive nature of their operations. A triumphant attack can disrupt patient care, compromise data privacy, and even endanger lives. Ransomware attacks, where hackers encrypt data and demand payment for its release, have become increasingly common, crippling hospital systems across the globe. According to the Cybersecurity and Infrastructure Security Agency (CISA), the healthcare sector remains a frequent target.
The Bern University Hospital Simulation: What Happened?
The disconnection at Bern University Hospital was a comprehensive test, impacting nearly all IT systems. The hospital aimed to evaluate its ability to maintain essential services, such as emergency care, using backup systems and manual procedures. This included assessing communication protocols, data recovery processes, and the coordination between different departments. The simulation was designed to mimic the conditions of a real cyberattack, forcing staff to operate under pressure and rely on choice workflows.
Lessons Learned and Best Practices
While the full results of the Bern University Hospital simulation haven’t been publicly released, similar exercises elsewhere have highlighted several key lessons. These include the importance of:
- Regular Backups: Maintaining up-to-date, offline backups is crucial for data recovery.
- Network Segmentation: Isolating critical systems from less sensitive ones can limit the spread of an attack.
- Incident Response Plans: Having a well-defined and regularly tested incident response plan is essential for a swift and effective response.
- Employee Training: Educating staff about phishing scams and other cyber threats is a vital preventative measure.
- Vulnerability Management: Regularly scanning for and patching vulnerabilities in software and hardware.
Proactive cybersecurity isn’t just about technology; it’s about building a culture of security awareness and resilience throughout the association.

The Future of Healthcare Cybersecurity
As cyber threats continue to evolve, healthcare organizations must adopt a proactive and layered approach to cybersecurity. Simulations like the one conducted by Bern University Hospital are becoming increasingly significant for identifying vulnerabilities and improving preparedness. Investing in robust security measures, fostering a security-conscious culture, and collaborating with cybersecurity experts are essential steps for protecting patient data and ensuring the continuity of care. The industry is also looking towards advancements in artificial intelligence (AI) and machine learning (ML) to enhance threat detection and response capabilities.
