시스템 보안 연구실 (SSLab)은 해킹에 열정 있는 학생들을 기다리고 있습니다. 저희 연구실은 뭔가를 만들고, 고장내고, 고치는 걸 좋아하는 해커 기질을 가진 여러분들을 찾고 있습니다. SSLab은 소프트웨어 및 시스템 보안 분야 연구를 중점적으로 연구하고 있고, 무엇보다 학생 한명 한명이 재미를 느끼는 주제를 찾고 또 깊게 파고들 수 있도록 적극 지원합니다. OS, Computer Architecture, Reverse engineering, Software Exploit Writing등에 대한 배경지식이 있으면 좋지만, 체계적인 신입생 교육 프로그램을 통해 배워나갈 수도 있습니다. SSLab의 철학은 구성원 개개인이 연구를 하는 가장 큰 동기부여가 재미가 되도록 하는 것입니다. 현재 저희 연구실은 아래와 같은 포지션을 모집하고 있습니다:
We are looking for passionate students interested in doing research at SSLab. The most important qualification we want from you is that you inherently enjoy hacking stuff. We student research topic is that you have fun exploring the topic. So, do not hesitate to talk to us if you are interested:) Currently, I have the following positions open :

Prof. Hojoon Lee is currently an assistant professor at Dept. of Computer Science and Engineering at Sungkyunkwan University since September 2019. Prior to his current position, he spent one year as a postdoctoral researcher at CISPA (Saarbruecken, Germany) under the supervision of Prof. Michael Backes. He received his Ph.D. from KAIST in 2018, advised by Prof. Brent Byunghoon Kang, and his B.S. from The University of Texas at Austin. His main research interests lie in retrofitting security in computing systems against today’s advanced threats. His research interests include but are not limited to Operating System Security, Trusted Execution Environments, Program Analysis, Software Security, and Secure AI Computation in Cloud.
