Network IDS/IPS Architecture

Designed and analyzed intrusion detection systems for a university project. Investigated real packet captures using Wireshark to identify attack lifecycles — from reconnaissance to data exfiltration. Applied signature-based, anomaly-based, and stateful protocol analysis aligned with NIST IDPS guidance.

About Me

I'm a cybersecurity student at Queen's University Belfast with a passion for understanding how systems can be broken and how to defend them.

When I'm not studying, I'm solving CTF challenges, building security tools, or contributing to the cybersecurity community. I believe the best way to learn security is by doing.

This site is where I document my journey from security games I've built to challenges I've conquered.
