Enhancing healthcare cybersecurity with Generative AI: A vital necessity

Guest blog by Daniel Brodie, Co-Founder and CTO at Cynerio #techUKCyber2023

In recent years, the United Kingdom has witnessed a concerning surge in cyberattacks targeting its healthcare sector. These attacks have raised significant alarm bells, not just for the healthcare industry but for the entire nation's security. While various factors contribute to this cyber onslaught, a lack of resources and expertise in the healthcare sector has played a pivotal role. However, there is hope on the horizon, as Generative AI is emerging as a powerful tool to bolster cybersecurity in healthcare.

The Rising Tide of Healthcare Cyberattacks

The healthcare industry has long been a target for cybercriminals, but the past few years have seen a noticeable increase in the frequency and sophistication of attacks. These incidents range from data breaches that compromise patient privacy to ransomware attacks that cripple essential healthcare services. The implications are far-reaching, affecting not only patient care but also eroding trust in healthcare systems.

Cynerio’s recent “The State of NHS Trust Iot Device Security” study provided much deeper insight into these trends than were previously available. Most notably, the study identified that 46% of the 35,424 devices analysed had at least one known security issue that was unaddressed. More alarmingly, 11.7% of those devices had at least one critical flaw that could impact patient care. The report also warns that these rates will likely continue to rise as the adoption of connected devices grows due to their ability to improve patient care.

Root Cause: Resource Constraints and Expertise Gap

A significant contributor to the vulnerability of healthcare systems lies in the lack of resources and cybersecurity expertise within the sector. Healthcare institutions often prioritise patient care over cybersecurity investments, leaving them exposed to evolving cyber threats. The shortage of cybersecurity professionals further exacerbates the problem, making it challenging to detect and respond to threats effectively.

Take the extreme case of Ireland’s Health Service Executive which experienced widespread outages due to a May 2021 cyber attack. The five month long attack resulted in encryption of 80% of IT systems across more than 40 facilities and cost the system an estimated €500,000,000. Upon further investigation it was determined that a lack of expertise including no director and an underfunded team were partially responsible.

Generative AI: A Beacon of Hope

Generative AI, with its remarkable capabilities in understanding and generating human-like text, images, and data, is emerging as a game-changer in healthcare. Recent innovations are leading to widespread adoption for administrative tasks, patient communication, and training simulations, but the impacts do not stop there. Generative AI is also making significant strides in healthcare cybersecurity.

Take for example Google's Med-Palm 2 and Sec-Palm. These groundbreaking projects are examples of how Generative AI is revolutionising healthcare cybersecurity. These platforms provide a solid foundation for the adoption of Generative AI in safeguarding healthcare data and systems.

Key Benefits of Generative AI in Healthcare Cybersecurity

The potential benefits of Generative AI in healthcare cybersecurity will take years to fully understand, but initial innovations already show the value of the resulting technologies:

Improved User Experience and Insight: Generative AI allows for dynamic creation of complex reports with simple prompts. For instance, the Cynerio platform enables users to request detailed information about unpatched devices in a specific location, streamlining the decision-making process.
Enhanced Back-End Analysis: The ability to rapidly analyse potentially malicious network traffic and raise event flags has become crucial. Generative AI can quickly sift through vast amounts of data, flagging suspicious activities for further analysis by cybersecurity experts.
Expedited Research: Generative AI accelerates research in cybersecurity, enabling faster development of new protections. It allows security professionals to delve deeper into threat analysis and devise robust countermeasures swiftly.

Accelerating Adoption: A Critical Imperative

While Generative AI holds immense promise for enhancing healthcare cybersecurity, it is vital to expedite its adoption. Cybercriminals are not resting; they are actively employing Generative AI to craft more convincing phishing emails and develop sophisticated malware. The battle for cybersecurity supremacy is intensifying, and healthcare organisations must leverage Generative AI to stay ahead.

The escalating cyber threats faced by the UK's healthcare sector demand immediate action. The fusion of Generative AI and healthcare cybersecurity is proving to be a powerful alliance. By embracing this technology, healthcare institutions can protect patient data, ensure the integrity of their services, and ultimately, save lives. The time to act is now, as attackers are continually evolving their tactics, and the future of healthcare cybersecurity depends on our ability to adapt and innovate.
