Abstract

Following the development of Internet of Things (IoT) technology, the scope of application of IoT technology is expanding to industrial safety areas that detect and prevent possible risks in outdoor environments in advance, away from improving the convenience of living in indoor environments. Although this expansion of IoT service provides many advantages, it also causes security problems such as data leakage and modulation, so research on security response strategies is being actively carried out. In this paper, the IoT-based road construction risk management system in outdoor environment is proposed as a research subject. As a result of investigating the security vulnerabilities of the low-power wide-area (LPWA, BLE) communication protocol applied to the research targets, the security vulnerabilities were identified in terms of confidentiality, integrity, and availability, which are the three major elements of information security, and countermeasures for each vulnerability were proposed. This study is meaningful in investigating and analyzing possible vulnerabilities in the operation of the IoT-based risk management system and proposing practical security guidelines for each vulnerability.

사물인터넷(Internet of Things: IoT) 기술 발전에 따라서, IoT기술의 적용범위는 실내 환경의 생활 편의성 개선에서 벗어나 실외 환경에서의 발생가능한 위험을 사전에 감지·예방하는 산업안전 분야로 확대되고 있다. 이러한 IoT서비스 확대는 많은 장점을 제공함에도 데이터 유출과 변조 등의 보안 문제도 함께 발생시키므로 이에 따른 보안 대응전략 연구도 활발히 진행되고 있다. 본 논문에서는 실외환경에서의 IoT기반 도로건설 위험방지시스템을 연구대상으로 IoT 보안관리 가이드라인을 제안한다. 연구대상에 적용한 저전력-광역(LPWA, BLE) 통신프로토콜의 보안취약점을 조사한 결과, 정보보안의 3대 요소인 기밀성, 무결성, 가용성 측면에서 보안취약점을 확인하여 이를 최소화할 수 있도록 취약점 별 대응방안을 제안하였다. 본 연구는 기 구현된 실외환경에서의 IoT기반 도로건설 위험방지시스템 운영에서 발생할 수 있는 취약점 조사·분석과 취약점별 실질적인 보안지침을 제안하는데 연구의 의의가 있다.
