Find out how a holistic approach, without the hindrances of a “checkbox mentality”, can guard healthcare institutions sophisticated cyber threats
The healthcare industry has long been a prime target for cyberattacks, but in recent years, threats have grown significantly in scale and sophistication.
A key reason why bad actors have caused damaging harm to healthcare organizations so regularly is complexity. Healthcare IT infrastructure is inherently complex, making it challenging to maintain a comprehensive view of the organization’s security posture.
A typical hospital’s IT ecosystem includes specialized medical devices, on-premises networks and applications, and cloud services — each with its own risk profiles and security logging approaches. Medical devices, in particular, pose unique security challenges. Many of these devices still rely on legacy operating systems that are difficult to patch, leaving them vulnerable to threats. Moreover, the critical nature of these devices often means they cannot be taken offline for updates or maintenance without impacting patient care, which further threatens the security gap.
The Checkbox Mentality and AI factors
Separately, healthcare organizations must comply with strict regulations to safeguard protected health information (PHI), which can add another layer of complexity to security operations.
While necessary to protect patient privacy, the regulations can lead to a “checkbox mentality”, where organizations prioritize compliance over maintaining a holistic, proactive security strategy.
Another factor that adds complexity to healthcare security is the ever-evolving tools and tactics leveraged against them. AI has democratized malware creation, enabling bad actors to create sophisticated threats without coding expertise. Worse still, the rise of Ransomware-as-a-Service and cybercrime-for-hire models — driven by groups such as LockBit, BlackCat and Hive — has made launching cyberattacks easier and more accessible than ever.
As a result, the volume and sophistication of threats targeting healthcare organizations have been growing steadily, putting patient data and critical operations at risk.
Filling out the right cyber prescription
To navigate the complexities of healthcare infrastructures and mitigate risks effectively, healthcare organizations need advanced tools that provide comprehensive visibility and actionable insights.
- First, a multi-layered approach is essential, starting with the integration of Zero Trust across the network and device monitoring.
- Technologies such as network traffic analysis (NTA) and user and entity behaviour analytics (UEBA) are critical in surfacing anomalies in network traffic or user behavior in real-time. This ensures that potential threats are identified early, offering security teams critical insights into instances of account abuse, insider threats, and non-compliant usage within healthcare systems.
- While NTA and UEBA are powerful tools on their own, their true potential is realized when integrated into a broader security strategy including security solutions such as Security Information and Event Management (SIEM) systems.
- When healthcare organizations create a more holistic view of their security posture, the integrated approach allows them to correlate data from multiple sources, reduce false positives, and enhance threat detection.
- AI is becoming an essential force multiplier in security operations — one that healthcare institutions can no longer afford to ignore. AI-powered capabilities offer healthcare institutions powerful tools to revolutionize security operations, boost efficiency and enable security teams to focus on the most critical threats. AI can be used to analyze vast amounts of data, including threat intelligence feeds, user behavior patterns and network activity, to help security teams focus on the most critical threats, allowing for more effective threat detection, investigation and response.
Armed with a unified dashboard, security teams can act faster and with more context, reducing the time it takes to mitigate risks and prevent breaches.
By incorporating AI and advanced analytics within a comprehensive security strategy, organizations can not only improve their ability to detect and respond to threats, but also strengthen their overall security posture for the future.
