Abstract

The speed of technological development is increasing, and high-performance digital devices are spreading. Wired digital devices such as PCs have been optimized for existing wired environments, but needs are shifting away from the constraints of space and space to smart work that enables efficient work anywhere and anytime. The Smart Work System security design is needed to secure integrity and availability in the face of various security threats including physical threats (lost, stolen, and damaged terminals), technical threats (data theft, DoS: denial of service), and unauthorized access outside the wired environment. In this study, we analyzed smart work network systems, wired / wireless link systems, and digital smart devices. We also studied cyber-attack analysis and cybersecurity design methods for a Smart Work wired system and a future wireless system. This study will be used as basic data for building a secure Smart Work system.

기술 발전 속도가 증가되고, 고성능의 디지털 기기가 확산되고 있다. 기존 유선 환경에 최적화 되어 제한적으로 활용되던 PC와 같은 유선 디지털 기기에서 시 공간의 제약에서 벗어나, 언제 어디서나 효율적인 업무 수행이 가능한 스마트워크로 전환되고 있다. 유선환경에 비해 물리적 위협(단말기 분실, 도난 및 파손 등), 기술적 위협(도난, 서비스 거부, 비인가 접근 등) 등 다양한 보안 위협에 대해 무결성과 가용성을 확보할 수 있는 시스템 보안설계가 필요하다. 본 논문 연구에서는 스마트워크의 네트워크시스템, 유 무선 링크시스템, 디지털 스마트기기를 분석한다. 현재 업무에 사용되고 있는 스마트워크 유선시스템과 향후 무선시스템을 위한 보안설계 방안을 연구한다. 본 연구는 안전한 스마트워크 구축에 기초자료로 활용될 것이다.
