Welcome to CNS Lab!

The Computing and Network Security (CNS) Lab, led by Prof. Jinwoo Kim at the Department of Computer Engineering in Chungbuk National University, investigates how both humans and intelligent systems perceive, reason, and act in the presence of emerging cyber threats. Our work spans cloud and networked infrastructures, including SDN and SD-WAN, container and serverless platforms, and WebAssembly runtimes, as well as application layer systems such as blockchain, social VR, and AI-driven environments. By analyzing threats at the human, system, and AI levels, we design intelligent, adaptive, and practical security mechanisms that enhance resilience in real-world deployments.

컴퓨팅 및 네트워크 보안 연구실(CNS Lab)은 충북대학교 컴퓨터공학과 김진우 교수가 이끌고 있으며, 인간과 지능형 시스템이 사이버 위협을 어떻게 인지하고, 판단하며, 대응하는지에 대한 연구를 수행합니다. 연구 분야는 SDN과 SD-WAN, 컨테이너 및 서버리스 환경, WebAssembly 런타임과 같은 차세대 클라우드·네트워크 인프라뿐 아니라, 소셜 VR, AI 기반 시스템까지 폭넓게 포함합니다. 본 연구실은 이러한 다양한 환경에서 발생하는 위협을 다층적 관점에서 이해하고, 이를 바탕으로 적응형 지능형 보안 기술을 설계하여 실제 시스템의 보안성과 신뢰성을 향상시키는 것을 목표로 합니다.
