Abstract

With the rapid development of the information society, the use of digital devices has increased dramatically and the importance of technology for analyzing them has increased. Digital evidence is stored in many places such as Prefetch, Recent, Registry, and Event Log even if the user has deleted it. Therefore, there is a disadvantage that the forensic analyst can not grasp the files used by the user at the beginning. Therefore, in this paper, we propose a method that the RemoveList folder exists so that the user can grasp the information of the deleted file first, and the information about the deleted file is automatically saved by using AES in RemoveList. Through this, it can be expected that the analyst can alleviate the difficulty of initially grasping the user's PC.

급격한 정보화 사회로의 발달로 사람들은 디지털기기의 사용이 급격히 증가하면서 이를 분석하는 기술에 대한 중요성이 증가하였다. 디지털 증거는 사용자가 삭제하더라도 Prefetch, Recent, Registry, Event Log 등 여러곳에 산재되어 저장되는 특성이 있다. 때문에 포렌식 분석관이 초기에 사용자가 이용한 파일들에 대해 완벽한 파악이 어렵다는 단점이 존재한다. 따라서 본 논문에서는 사용자가 직접 삭제한 파일에 대한 정보를 먼저 파악할 수 있도록 RemoveList 폴더가 존재하고, RemoveList에는 AES를 이용하여 삭제된 파일에 대한 정보가 암호화되어 자동 저장되는 방안을 제안하고자 한다. 이를 통하여 분석가가 초기에 사용자의 PC를 파악하는 것이 어렵다는 문제점을 완화할 수 있다는 기대를 할 수 있다.
