Summary
In 1998, at the time of middle school ago, I took first step into security field in an online activity of a UNITEL. and I joined a community of HackersLab at Chung-buk province as a start-up member. At first I liked to attack but hacked by other hackers. so I realized the importance of defense against the attacks. Since then, I entered into an university as a security specialist and researched IDS, malicious code in a security club activity. I operated several security systems and large-scaled server in the Army as a CERT member, When I served in ZAYTUN Division at Iraq, I made a special Anti-Virus for a malicious code which couldn’t be removed by existing Anti-Virus. I won several prizes until finished my duty. When I returned to the University, I worked in a Anti-virus company as a malicious code analyst. I has been a chairperson in a security club union of universities and made presentations in several security conference in Korea.
