초록

네트워크 기반 단말 정보 식별 도구는 일반적으로 포트 스캔을 사용해 네트워크 단말들의 정보를 탈취하고 취약점을 찾아낸다. 특히 Shodan과 Censys는 네트워크 기반 단말 정보 식별 도구를 이용하여 광범위한 단말 정보를 탈취하여 데이터베이스에 저장한 후, 이를 사용자에게 제공한다. 이 정보는 누구나 확인할 수 있기 때문에 사이버 공격에 악용될 수 있다. 따라서 네트워크 단말 정보 탈취 방지가 필요하며, 이를 위해서는 스캔 도구가 사용하는 스캐닝 방법을 알아야한다. 하지만 Shodan과 Censys가 사용하는 스캐닝 방법은 잘 알려져 있지 않다. 따라서 본 논문에서는 Shodan과 Censys의 스캐닝 방법을 추정해 모델링하고 성능을 분석하였다.

Network scanning tools typically use port scans to steal information from network terminals and identify vulnerabilities. In particular, Shodan and Censys use a network scanning tool to gather a wide range of terminal information, store it in their database and provide it to the users. In order to prevent such information gathering, it is required to know the scanning methods of Shodan and Censys. However, the scanning model used by Shodan and Censys is not known exactly. Therefore, this paper estimates scanning models of Shodan and Censys and analyzes the performance of each models.
