(March 1 2022) Prof. Jinwoo Kim joined the School of Software at Kwangwoon University.
The Cloud and Network Security (CNS) Lab, led by Prof. Jinwoo Kim at Kwangwoon University, conducts research on security and reliability challenges in emerging cloud and networked systems. Our interests span software-defined infrastructure (e.g., SDN, SD-WAN), container-based and serverless platforms, and application-layer systems such as blockchain, social VR, and AI-driven environments. We aim to understand fundamental risks and design practical security mechanisms tailored to real-world threats in these domains.
클라우드 및 네트워크 보안 연구실(CNS Lab)은 광운대학교 소프트웨어학부 김진우 교수가 이끌고 있으며, 클라우드 및 차세대 네트워크 시스템에서의 보안 및 신뢰성 문제를 연구합니다. 연구 주제는 SDN/SD-WAN 기반 인프라, 컨테이너 및 서버리스 환경, WebAssembly 보안 등 인프라 영역뿐만 아니라, 블록체인, 소셜 VR, AI 기반 응용 시스템의 보안 이슈까지 폭넓게 다룹니다. 본 연구실은 실제 환경에서 발생하는 위협을 이해하고, 이를 해결할 수 있는 실용적인 보안 방안을 설계하는 데 중점을 두고 있습니다.
