Area of Science:

  • Health Informatics
  • Information Systems Architecture
  • Cybersecurity in Healthcare

Background:

  • Existing healthcare information systems require integration and evolution to meet increasing demands.
  • The CEN ENV 12967-1 standard, known as Healthcare Information Systems Architecture (HISA), offers a solution.
  • HISA promotes interoperability through a middleware of common business services.

Purpose of the Study:

  • To provide an overview of the key aspects of the HISA standard.
  • To discuss the integration of authorization and security within the HISA framework.
  • To propose a global security framework for healthcare information systems.

Main Methods:

  • Review of the CEN ENV 12967-1 HISA standard.
  • Analysis of architectural positioning for security and authorization.

  • Development of a proposed global security framework.

    • Main Results:

    • HISA enables seamless operation across local and geographical systems using a common information heritage.
    • The paper details the placement of security and authorization within the HISA architecture.
    • A comprehensive global security framework is presented.

    Conclusions:

    • The HISA standard is essential for modernizing healthcare information systems.
    • Effective integration of security and authorization is vital for robust healthcare IT infrastructure.
    • The proposed framework enhances the security posture of integrated healthcare systems.
