About Jinseok Yeom

# Hello! I'm **Jinseok Yeom**, founder and operator of the JSYCURE team. I am a graduate researcher with a focus on applied cybersecurity, security automation, and the design of resilient infrastructure for both academic and operational environments. ## About Me My work sits at the intersection of detection engineering, security orchestration, and full-stack infrastructure development. I am particularly interested in how modern machine learning techniques can be integrated into traditional security operations, and how open-source tooling can be combined to build production-grade defensive systems without commercial dependencies. Beyond research, I enjoy building end-to-end systems — from physical lab infrastructure to user-facing web applications — and treating each component as part of a single, coherent security architecture. ## Education - **M.S. in Cybersecurity** — Ajou University *(in progress)* - Research focus: AI-based intrusion detection, security automation, and SOC infrastructure design - **B.S. in Computer and Software Engineering** — Wonkwang University *(graduated)* - Foundation in software engineering, networking, and systems programming ## Technical Stack ### Languages Node.js, Python, JavaScript, with working experience in Bash scripting and SQL for data manipulation and automation. ### Infrastructure & DevOps Proxmox VE for virtualization, Ubuntu Server as the primary Linux distribution, Nginx for reverse proxying and TLS termination, Tailscale for zero-trust network access, systemd for service management, and Let's Encrypt for automated certificate provisioning. ### Security Hands-on experience with SIEM platforms (Wazuh, ELK Stack), SOAR tooling (TheHive, Shuffle), intrusion detection systems (Suricata, Zeek), penetration testing fundamentals using Kali Linux, and network segmentation design with OPNsense. ### Databases SQLite for embedded and lightweight applications, PostgreSQL for relational data at scale, with familiarity in query optimization and schema design. ### Web Development Express.js for backend services, EJS for server-side templating, REST API design, session-based authentication, and secure handling of user data following industry best practices. ## Projects ### JSYCURE Cloud — Self-Hosted Cloud Management Platform A full-stack web platform that consolidates cloud VM provisioning, user management, and team operations into a single self-hosted interface. The project was created to replace a Naver Cafe-based workflow that previously handled VM requests for our community. Key features include: - User registration, login, password recovery, and account self-service - VM request submission, administrative approval, and lifecycle management - Real-time monitoring of Proxmox-based virtual machines via the Proxmox REST API - Notice board with role-based posting permissions and email broadcast - Integrated notification system for users and administrators - Hardened deployment with HTTPS, rate limiting, helmet-based security headers, and audit logging The platform is currently live at `jsycure-cloud.duckdns.org`, running on Node.js, Express, EJS, and SQLite, with Nginx serving as the reverse proxy. ### DeepSecu — AI-Based Intrusion Detection Research A research initiative focused on applying deep learning to network and host-level intrusion detection. The project explores how modern neural network architectures can complement signature-based detection systems by identifying behavioral anomalies that traditional rules cannot capture. Current research directions include adversarial robustness, model explainability, and the integration of large language models for triage assistance. ### Ongoing Personal Projects - Building a unified SOC dashboard that aggregates events from multiple detection sources - Designing a lightweight honeypot system for collecting and analyzing real-world attack traffic - Developing custom Suricata and Zeek detection rules tailored to lab environments - Experimenting with LLM-assisted incident triage workflows - Continuous improvement of the JSYCURE Cloud platform with new features and security hardening ## Contact - **GitHub**: [Jinseok-Yeom](https://github.com/Jinseok-Yeom) - **Email**: itsafe.official@gmail.com Feel free to reach out for collaboration, research discussion, or any inquiries related to security operations, infrastructure, or web development.
