A security architecture for health information networks.

Area of Science:

• Health Informatics
• Network Security
• Cybersecurity in Healthcare

Background:

• Healthcare enterprises face challenges in implementing stringent security controls for health information networks.
• Sharing confidential health data over insecure networks like the Internet necessitates robust security architectures.
• Existing nationwide health information network architectures require enhanced security measures for inter-network data sharing.

Purpose of the Study:

• To propose a minimum set of security controls for health information networks.
• To enable secure inter-network data sharing while balancing security with practicality.
• To achieve network security and privacy goals including confidentiality, integrity, and availability.

Main Methods:

• Abstracting network security requirements based on health network data flow patterns and trust models.
• Developing a framework combining technology mechanisms with environmental controls.
• Analyzing common network security threats to health information networks.

Main Results:

• A core set of security requirements was identified for secure inter-network data sharing.
• The proposed framework integrates technology and environmental controls for comprehensive security.
• The framework is demonstrated to be sufficient against common network security threats.

Conclusions:

• A practical and implementable framework for health information network security is presented.
• The proposed minimum security controls effectively address confidentiality, integrity, and availability.
• The framework supports secure sharing of sensitive health data across networks without major technological overhauls.
