Medical networks require robust security to protect sensitive data. This paper explores network threats and cryptographic solutions to ensure confidentiality, integrity, and access control in healthcare information systems.

Area of Science:

  • Computer Science
  • Information Security
  • Medical Informatics

Background:

  • Hospital Information Systems (HIS) require interconnected networks for data exchange and accessibility.
  • Open-network environments using OSI protocols facilitate multi-vendor system integration.
  • Information security on individual hosts is vulnerable to network-wide threats and other connected systems.

Purpose of the Study:

  • To identify and describe security threats in open-network medical environments.
  • To establish essential security requirements for medical communication networks.
  • To present cryptographic mechanisms for enhancing network security.

Main Methods:

  • Analysis of security threats including computer viruses, passive attacks (e.g., wire-tapping), and accidental unauthorized access.
