공용 무선공유기 비밀번호 선정 방식의 위험성 분석

In wireless network environments with wireless access points, many vulnerabilities and attack methods are reported due to easy access, and real damage cases have been reported. The purpose of this study figures out the risk of the password selection for public wireless access points. For the purpose, we surveyed the previous researches on attacks of the wireless network system, protocols, and password-based authentication, and the problem of the user password selection also. We conducted a case study to figure out the risk for wireless access points, and proposed a guessing method with fewer than 20 attempts through the analysis of the current passwords. It is shown that the password of most public wireless access points in the other region can be easily guessed. In addition, we emphasized the risk of the way of choosing passwords by presenting an additional security threat scenario when the passwords are exposed.
