Abstract

Governments and public agencies try to use the cloud to carry out their work and provide public services. However, a public cloud is vulnerable to security side because it has a structure to support services using public networks (i.e, the internet). Thus, this paper finds the general security vulnerabilities of a network and compares and analyzes the characteristics of transport protocols (UDP, TCP, SCTP, and MPTCP) on the basis of their security vulnerabilities. This paper uses a reliability and security factor for the comparative analysis, evaluates the security exposure, and chooses a suitable protocol considering the security of the transport protocols in the cloud circumstance.

정부 및 공공기관에서는 업무 및 서비스 제공에 있어 공공망을 활용한 클라우드 서비스를 촉진하고자 하나 공공망(인터넷)을 이용하는 구조로 인해 보안상의 취약점이 발생하기 쉽다. 이에 본 논문에서는 공공망을 사용하는 클라우드 네트워크의 일반적인 보안 취약점을 도출하고, 이를 기준으로 UDP와 TCP 계열 프로토콜(TCP, SCTP, MPTCP)의 보안 관련 특성을 비교 분석하였다. 비교 분석에는 신뢰성 및 보안성 요소를 사용하였으며, 보안 노출도를 평가하고 전송 프로토콜 중 보안성 측면에서 가장 적합한 프로토콜을 선정하였다.
