Healthcare organizations face significant challenges in device security, often exacerbated by what can be characterized as turf wars between various teams, including healthcare technology management, operational technology staff, IT departments, and security units. This fragmentation stems from unclear ownership and accountability mechanisms around device security, posing a potential risk to patient safety, according to Mohammed Waqas, Chief Technology Officer at Armis.
As the healthcare sector increasingly embraces network-connected medical equipment and operational technologies, the visibility of these devices to cybersecurity teams diminishes. Many devices are deployed without adequate oversight, with the assumption that IT or security teams, or external vendors, will address issues only when they escalate. This reactive approach may inadvertently leave organizations vulnerable to security threats.
Simultaneously, while security teams routinely identify and flag vulnerabilities, remediating these issues often falls into the hands of asset-owning departments, which may lack the necessary resources or expertise. Waqas noted that the confusion surrounding who is ultimately responsible for ensuring that assets adhere to cybersecurity policies intensifies the problem. When these discussions shift to focus on patient care and safety, the urgency of addressing these security vulnerabilities becomes evident, moving beyond mere cybersecurity concerns to critical hospital operations.
To effectively tackle these challenges, strong governance, collaboration, and communication among teams are essential. Waqas emphasizes the importance of facilitating dialogue among various stakeholders, including C-level executives and Chief Information Security Officers (CISOs). By framing discussions around the impact on patient care and safety, organizations are more likely to foster cooperation and commitment from all involved parties, aligning interests towards shared goals.
In a recent interview with Information Security Media Group, Waqas elaborated on several pressing concerns. He highlighted the necessity of collaboration between IT security teams and health technology management to effectively address vulnerabilities in medical devices. Furthermore, he stressed the critical role of conveying to leadership the potential impacts that security vulnerabilities could have on patient care and overall safety.
Waqas also provided insights on enhancing collaboration and understanding among teams that deal with medical device cybersecurity. His extensive experience in the healthcare cybersecurity industry positions him uniquely to advise organizations on securing unmanaged, Internet of Things (IoT), and medical devices.
As organizations face a more complex cybersecurity landscape, it is essential to recognize the potential tactics that adversaries may employ, as outlined in the MITRE ATT&CK Matrix. Techniques such as initial access, persistence, and privilege escalation may be employed by threat actors to exploit vulnerabilities within healthcare systems. Understanding these tactics offers organizations a roadmap to fortifying their defenses.
In summary, the need for clarity in ownership, enhanced collaboration among teams, and a focus on patient safety are paramount for healthcare organizations looking to navigate the complexities of device security. As the sector continues to evolve, staying informed and proactive in addressing these cybersecurity challenges will be vital in safeguarding both technology and patient well-being.
