Recently, the leaking of personal information due to cyber attacks has become never ending. Because the methods of attacks have become more sophisticated, it is difficult to prevent them. When a security incident occurs, it is necessary to localize the damage through rapid detection and response. In this presentation, I will introduce visualization and methods for effectively detecting attacks using big data, in this case, huge log data. Along with introducing cyber attack methods, I will suggest how to use big data for cyber security by analyzing logs.
Participants will learn about:

• Methods of attack, such as targeted attacks.
• How to use logs to detect attacks.
