Essential cybersecurity measures for hospitals

Some time ago, we discussed the importance of cybersecurity in the healthcare sector, outlining the current landscape of cyberattacks and why investing in IT security is crucial. We explained the most common and frequent cyberattacks in this sector that have caused significant disruption in hospitals, the most serious being at the Hospital Clínic of Barcelona.

After examining the types of threats healthcare organizations face, today we want to focus on the essential cybersecurity measures they should invest in to prevent a cyberattack.

Essential cybersecurity measures in hospitals

Having documented cybersecurity procedures and policies

Documenting cybersecurity processes and protocols is essential so that all hospital staff know how to respond to a potential cyberattack.

Hundreds of people work across the various areas of a healthcare facility, making organization, coordination, and documentation critical to ensure everyone knows how to act. Staff turnover is common in hospitals, so having protocols that explain how to proceed is vital.

Additionally, hospital cybersecurity policies should include risk management plans and incident response plans.

Staff awareness

Hospitals and healthcare centers are increasingly aware of how they must handle data and the sensitivity of the information they manage. However, each facility can establish its own cybersecurity policies and protocols. Cyberattacks are constantly evolving, which is why periodic cybersecurity training, updated and aligned with the facility’s IT security strategies, is important. Training also helps new staff become familiar with these protocols.

Controlling access to information

In a hospital, some staff members may not need access to patient information or sensitive data from suppliers, collaborators, medications, formulas, etc., depending on their role. Each department or area should only access the information relevant to their work. Limiting access helps prevent data leaks.

Implementing cybersecurity solutions on devices and networks

Keeping devices updated, implementing firewalls and antivirus software, using anti-phishing solutions, and performing backups are some of the primary—and practically mandatory—solutions hospitals should have to prevent malware from entering their systems.

Email security is particularly important, as discussed in the article.

Data encryption and regulatory compliance

Encrypting data both at rest and in transit is crucial to prevent unauthorized access. Additionally, medical data must comply not only with the General Data Protection Regulation (GDPR) but also with the Health Insurance Portability and Accountability Act (HIPAA) and other local data privacy regulations.

Maintaining backups

Regular backups are essential so that, in the event of data theft, information can be quickly restored. However, not all backup solutions are reliable, as cybercriminals can sometimes encrypt the backups themselves. At ESED, we use a backup solution that accounts for this possibility, combining multiple types of backups to ensure data is always accessible.

Continuous cybersecurity audits and validations

Just as diseases and viruses evolve, so do cyberattacks. As technology advances, attacks become more sophisticated, and security solutions that were effective a year ago can become obsolete. That’s why continuous cybersecurity audits and validations are essential.

Taking these precautions and implementing the cybersecurity measures mentioned above is the best way for hospitals to prevent and reduce the risk of cyberattacks.

At ESED, as cybersecurity specialists, we recommend reviewing the following success case to understand the real challenges and threats facing the healthcare sector and how to minimize the risk of a cyberattack.
