Military Information Leak Response Technology through OSINT Information Analysis Using SNSes

Open-source intelligence (OSINT), an information gathering and analysis system that utilizes public information on SNSes, is a necessary information gathering activity to counter terrorism and cyberterrorism. Although it is not possible to patrol cyberspace directly, as in real space, cyberspace can be patrolled by collecting information using OSINT technology. In this study, OSINT information analysis activities related to military information leakage are presented to SNSes. In this study, two or more OSINT collection tools are used to search for military information keywords, for characters’ names, and for personal identification information about the characters. The results of 100,209 cases of military information keyword search and 471 cases of name search are presented. It was also confirmed that personal identification information was not searched because of the strengthening of personal information protection.
