Physically Isolated Medical Networks to Block Ransomware and Ensure 24/7 Emergency Service Continuity

Modern healthcare services rely heavily on Electronic Medical Records (EMR), medical imaging systems, in-hospital automation equipment, and telemedicine platforms. Once the network is compromised by ransomware or external cyberattacks, it may not only disrupt medical operations but also pose serious risks to patient safety.

ShareTech Healthcare Cybersecurity Solution adopts a “physical network segmentation” architecture combined with multilayered security protection to effectively defend against ransomware, brute-force attacks, SQL injection attacks, and phishing intrusions. This prevents attackers from infiltrating critical medical systems through administrative networks or public Wi-Fi environments.

The solution further integrates Sandstorm malicious file analysis, Web Application Firewall (WAF) protection, encrypted VPN tunnels, and advanced firewall policies to ensure uninterrupted operation of HIS, PACS, LIS, nursing stations, emergency services, and telemedicine systems.

By establishing a 24/7 resilient cybersecurity environment, ShareTech enables healthcare institutions to maintain continuous and secure medical services, allowing healthcare professionals to focus on saving lives while the backend infrastructure remains fully protected.

1. Physical Network Segmentation for Internal Security

Hospitals accommodate a large number of patients, visitors, and third-party personnel every day. If guest Wi-Fi networks share the same infrastructure as medical devices and internal systems, they can easily become entry points for cyberattacks.

Through firewall-enforced physical traffic separation and logical network segmentation between the “medical/administrative internal network” and the “patient/guest external network,” ShareTech ensures that even if external networks are compromised or infected with malware, critical healthcare systems such as HIS and PACS remain fully isolated and protected from lateral threats.

2. Proactive Ransomware Protection for Medical Records Security

To address the growing threats of ransomware attacks targeting the healthcare industry, ShareTech provides multi-layer defense architecture designed to proactively detect and block malicious activities.

By integrating AI-powered Sandstorm with advanced malware filtering engines, suspicious and unknown malicious files can be identified and intercepted before entering the healthcare network. This prevents electronic medical record databases from being encrypted or held hostage by ransomware, ensuring the protection of hospitals’ critical digital assets and sensitive patient data.

3. Ensuring Continuous Healthcare Operations with DDoS Protection

In the healthcare industry, every second matters, and critical systems must always remain operational. ShareTech incorporates built-in Anti-DDoS (Distributed Denial-of-Service) protection mechanisms to effectively detect and filter malicious traffic, preventing healthcare servers from being overwhelmed or disrupted by cyberattacks.

Combined with High Availability (HA) redundancy architecture, the solution ensures uninterrupted operation of essential medical services such as patient registration, pharmacy dispensing, and clinical consultations, maintaining stable and reliable healthcare operations 24/7.

4. Web Application Firewall (WAF)

Healthcare databases store large volumes of sensitive patient information and insurance-related records, making them prime targets for cyberattacks. ShareTech provides Web Application Firewall (WAF) protection with advanced SQL Injection prevention capabilities to safeguard web applications and backend databases from unauthorized access and exploitation attempts.

By blocking attackers from leveraging web application vulnerabilities to steal confidential data, the solution helps healthcare institutions comply with cybersecurity and data protection regulations while preserving patient trust and institutional reputation.

5. 4G LTE High-Reliability Cybersecurity Solution

For mobile healthcare vehicles providing medical services such as health insurance consultations, X-ray imaging, and telemedicine in rural and community areas, ShareTech offers a dedicated cybersecurity solution integrating 4G LTE connectivity with advanced security protection to ensure stable and secure medical operations.

Designed for environments with unstable network coverage, the solution supports dual 4G LTE WAN redundancy to maintain uninterrupted registration systems and remote video consultations even in mountainous or remote regions. Through ZTA VPN encrypted transmission, sensitive medical records and X-ray images are securely protected from interception, ensuring compliance with cybersecurity and healthcare data protection regulations.

The platform also features built-in Intrusion Prevention System (IPS) and Sandstorm malware filtering technologies, specifically designed to protect legacy medical devices running outdated operating systems such as Windows XP, Vista, 7, and 8 from vulnerability-based attacks. In addition, the system adopts a rugged industrial-grade chassis with fanless thermal design, delivering high durability and reliable operation for demanding mobile healthcare environments.
