모바일 인스턴트 메신저(MIM) 환경에서 디지털포렌식 기술을 활용한 보안 감사 기술

Abstract

Today, After the spread of smartphones began in earnest in 2009, the use of smartphones has become so common that the majority of the people use them. As the use of smartphones has become popular, in the past, ways of communicating with others through text messages (SMS), calls, and e-mails have been exchanged, but today they are contacting them through a mobile instant messenger service (MIM). The main reasons for using the mobile messenger app service were in the order of personal contact with family and acquaintances, in-house business, and external customer service. In the case of external customer service, a mobile instant messenger service is used by the customer for response and business conference calls. In the case of instant messenger service (MIM), which is being used for customer service due to its nature of work, DLP can control instant messenger service (MIM) through application execution policies, but if it is to be allowed for business purposes, potential risks of internal information leakage exist due to the nature of instant messenger service (MIM). Therefore, when internal information is leaked through KakaoTalk, an instant messenger service, we propose a security audit methodology through digital forensics.
