A Study of Unidirectional Data Transmission System Security Model for Secure Data transmission in Separated Network

Abstract

Act on Promotion of Information and Communications Network Use and Information Protection」 is revised in August 18, 2012. The law requires the network isolation to company that hold 1 million people or more than your personal information and revenue 10 billion won or more telecommunications service providers. Unidirectional Data Transmission System is very important in separated network.

[13-912-06-005, 클라우드 환경에서 가상화 네트워크 및 시스템의 보안성 평가를 위한 보안 스캐너 개발] A Study of Unidirectional Data Transmission System Security Model for Secure Data transmission in Separated Network Copyright c 2015 HSST 540 Unidirectional Security Gateways is gateway to maintain security of protected network. But development Companies of Unidirectional Data Transmission System think that work efficiency is the important than security. In this paper, for secure data transmission between a separated network we propose a Security model for Unidirectional Data Transmission System.
