Security of computer systems, from the microarchitecture to the cloud.

The Computer Systems Security Lab (CSL) at Korea University is led by Prof. Youngjoo Shin and based in the School of Cybersecurity. We investigate how modern systems — from CPUs and GPUs to kernels, containers, and cloud fabrics — leak information or fail under adversarial conditions, and we design practical defenses against those failures.

Research Areas

Microarchitectural Attacks

Side channels and transient execution on CPUs, GPUs, and TEEs (SGX / TDX, Apple Silicon).

System Security

OS kernel defenses, system-call filtering, and secure execution.

Cloud & Container Security

Isolation and denial-of-service resilience in container/Kubernetes stacks.

Network Security

TLS, DNS, and network-function security in real deployments.

Binary Analysis & Fuzzing

Static and dynamic program analysis for vulnerability discovery.
