Cybersecurity in hospitals and IoMT devices: critical risks, applicable regulations, and how to avoid penalties

Hospitals and healthcare centers have become one of the main targets of cybercriminals. In Spain alone, ransomware attacks have increased by more than 116%, while the digitalization of healthcare has multiplied the number of devices connected to the network.

The problem goes far beyond a financial loss. A cyberattack can put critical systems out of service, prevent access to medical records, or compromise highly sensitive data belonging to thousands of patients.

For this reason, more and more healthcare organizations are asking how to protect their infrastructures, reduce the risk of suffering an incident, and comply with the requirements of regulations such as the GDPR or the NIS2 Directive.

What is IoMT and why does it represent a cybersecurity challenge?

The Internet of Medical Things (IoMT) includes connected medical devices capable of collecting, processing, and transmitting clinical information, such as infusion pumps, ventilators, diagnostic equipment, pacemakers, or remote monitoring systems.

These devices improve healthcare by providing real-time information, but they also expand the attack surface. Many remain in service for years, are difficult to update, and were not designed with cybersecurity as a priority, meaning that a compromised device can facilitate access to the rest of the hospital network.

Main cybersecurity risks in hospitals

Protecting a healthcare environment requires much more than installing antivirus software. A hospital manages thousands of devices, applications, and users that constantly exchange information. Among the most common risks are:

• Unauthorized access to medical records.
• Ransomware attacks that paralyze healthcare activity.
• Theft of personal and healthcare data.
• Vulnerable or outdated IoMT devices.
• Lateral movement of an attacker within the network.
• Disruption of critical services.

When any of these situations occurs, the impact does not affect only the organization. It can also delay diagnoses, surgical procedures, or treatments, directly compromising patient care.

How to protect a hospital against a cyberattack?

The best strategy is to implement a preventive (proactive) cybersecurity model that detects anomalous behavior before it becomes an incident. The objective is to reduce the attack surface and continuously protect the entire technological infrastructure.

To achieve this, it is advisable to segment the network, apply Zero Trust policies with multi-factor authentication, maintain an up-to-date inventory of connected assets, and continuously monitor activity. These measures should be complemented by vulnerability assessments, penetration testing, and verified backups to ensure rapid recovery from any incident.

Which regulations must a hospital comply with?

The healthcare sector is subject to some of the most demanding cybersecurity requirements due to the high level of sensitivity of the information it manages.

What can happen if a hospital does not adequately protect its infrastructure?

In the healthcare sector, a cyberattack can have much more serious consequences than in other industries. In addition to the operational impact, the organization may face significant legal and financial liabilities. Among the main consequences are:

• Fines of up to €10 million or 2% of annual turnover, according to the GDPR, when a serious personal data breach occurs.
• Penalties established by the NIS2 Directive for entities required to comply with it.
• Partial or total disruption of healthcare activity.
• Exposure of medical records and other highly sensitive information.
• Loss of trust from patients, insurers, and public organizations.

In a hospital, every minute of downtime can directly affect the quality of healthcare. Therefore, prevention is much more effective and less costly than dealing with the consequences of an incident.
