A Security Awareness and Protection System for 5G Smart Healthcare Based on Zero-Trust Architecture

Area of Science:

• * Information security in telecommunications and healthcare systems.
• * Development of advanced network security architectures.

Background:

• * Fifth-generation (5G) networks offer high bandwidth, low latency, and high concurrency, enabling advanced smart healthcare applications.
• * Existing security measures in legacy medical platforms are insufficient for distributed 5G healthcare systems, particularly for cloud-edge-terminal data sharing.
• * The increasing reliance on 5G in healthcare necessitates robust security for critical data and services.

Purpose of the Study:

• * To propose a novel security awareness and protection system for 5G-based smart medical platforms.
• * To leverage zero-trust architecture for dynamic access control and real-time security monitoring.
• * To address the security challenges posed by the distributed nature and data-sharing requirements of 5G healthcare.

Main Methods:

• * Development of a security system based on zero-trust architecture.
• * Integration of four key dimensions: subject (users, terminals, applications), object (data, platforms, services), behavior, and environment.
• * Implementation of trustable dynamic access control models, real-time security situational awareness, continuous identity authentication, access behavior analysis, and fine-grained access control.

Main Results:

• * The proposed system successfully constructs dynamic access control models.
• * Achieved real-time network security situational awareness and continuous identity authentication.
• * Demonstrated effective analysis of access behavior and fine-grained access control.
• * Industrial-grade implementation and testing confirmed system efficacy.

Conclusions:

• * The developed security system provides active defense and end-to-end security enforcement for data, users, and services in 5G smart medical systems.
• * The zero-trust architecture effectively addresses the security vulnerabilities of 5G-enabled healthcare.
• * The system meets the critical security needs for emerging healthcare challenges in the 5G era.
