Background: Safeguarding Critical Healthcare Environments
South Korea’s largest medical institution, a vast hospital system comprising 8 campuses across the country, including medical schools, cares for over 15,000 patients daily with the support of more than 8,000 employees. Operating in a highly dynamic environment, with doctors, patients, medical staff, contractors, and visitors using a wide range of medical devices, a very high level of security is paramount. The primary goal is to ensure the protection and confidentiality of sensitive patient information. Critically, the hospital must continuously address and resolve cybersecurity challenges without disturbing its vital, day-to-day operations.
Addressing Core Network and Device Management Challenges
The hospital sought a versatile NAC solution to address specific challenges hindering its security posture:
- Mobile Device & User Visibility: Lack of complete visibility into mobile devices and end-users across all campus environments.
- Ineffective Authentication: Suboptimal user authentication processes.
- Inappropriate Network Access: Risks of unauthorized access to sensitive intranet systems.
- Insufficient Endpoint Management: Inadequate patch and antivirus management, leading to endpoint security and compliance issues.
Solution: Genians NAC Delivers Comprehensive Healthcare Security
Genians enabled the hospital to establish a secure user authentication and authorization process by acquiring complete network visibility and seamlessly integrating with the hospital’s existing intranet system. The Genians NAC solution provides:
- 360º Network Surveillance: A real-time “bird’s-eye view” of all IP-enabled devices via Genians’ non-disruptive sensing technology, instantly classifying diverse device types (e.g., doctors’ tablets, nurses’ laptops, medical devices, visitor devices).
- Consolidated Authentication: Simplifies complex user/device authentication by unifying multiple methods (Web-based, Agent-based) into a comprehensive single-sign-on approach that provides role-based access.
- Automated Endpoint Management: Installs and maintains all required software and patches on time, and ensures proper Windows security settings.
- Secure Onboarding & Access Control: Provides a safe and secure onboarding process for Guest and BYOD scenarios, proactively blocking unknown, unauthorized, insecure, or rogue devices and isolating them from hospital networks.
- Anomaly Detection & Remediation: Actively detects and controls anomalies such as ARP bombing, MAC/IP cloning, and port scanning. It also quarantines and remediates non-compliant or compromised devices by integrating with existing security solutions like firewalls and SIEM systems.
- Comprehensive Audit Trail: Logs all activities to provide a complete audit trail for all IP-enabled devices, facilitating compliance demonstration and audit report generation.
Summary: Enhanced Patient Data Protection, Uninterrupted Care
By employing Genian NAC, the hospital system gained comprehensive network surveillance capabilities. This allows it to monitor its entire IT network infrastructure, including all IP-enabled devices, and detect any status changes in devices, users, IT assets (installed hardware and software), network connectivity, and vulnerabilities.
Streamlined Compliance and Unparalleled Availability
Genians empowers the hospital to correlate all gathered network data into actionable intelligence, supporting its regulatory compliance needs. By simplifying the complexity of critical user/device authentication and achieving full integration with existing systems, Genians provides a centralized and intuitive management interface. The hospital can now ensure the highest levels of system security, availability, and regulatory compliance, all without disturbing its crucial, day-to-day operations.
