Enhancing Healthcare Data Security: Mitigating Ransomware Threats to Network-Attached Storage (NAS) Systems for Real-Time Access and Compliance
Main Article Content
Abstract
Ransomware attacks have become one of the most significant cybersecurity threats in the healthcare sector, particularly targeting Network-Attached Storage (NAS) systems that store and manage critical patient data, including Electronic Health Records (EHRs) and medical imaging. As healthcare organizations increasingly rely on NAS devices to provide real-time access to healthcare data, vulnerabilities within these systems—such as outdated software, weak access controls, and insufficient encryption—have made them prime targets for cybercriminals. The consequences of such attacks include the loss or corruption of patient data, significant downtime, and disruptions in patient care, which can jeopardize lives and lead to non-compliance with regulations such as HIPAA. This paper proposes a comprehensive solution to mitigate ransomware threats to NAS systems in healthcare environments by implementing end-to-end encryption, regular system updates, and advanced intrusion detection systems (IDS). These measures ensure the protection of patient data, preserve real-time access to critical healthcare information, and minimize the operational impact of ransomware attacks. Additionally, this approach offers stronger cybersecurity, reduces downtime, and enhances the resilience of healthcare organizations to cyber threats. By adopting these strategies, healthcare providers can improve data security, ensure compliance with regulations like HIPAA, and safeguard patient care continuity. The implementation of encryption and IDS can not only prevent unauthorized access but also enhance the ability of organizations to detect and respond to ransomware attacks in real-time, ensuring that patient data remains available and intact. This solution provides healthcare organizations with an effective, proactive defense mechanism against evolving ransomware threats, thereby enhancing operational efficiency and improving service delivery.
