Cybersecurity Lab & Notes

ondrej@lab:~$ whoami

I’m an automotive software engineer expanding my knowledge and hands-on experience in cybersecurity. This site is my public notebook and portfolio.

I document what I build, test, and learn, with a strong focus on repeatable, evidence-driven work.

ondrej@lab:~$ ls ./content

lab Practice posts IDS/IPS investigations, detection engineering, playbooks, scripts, lab build logs

theory Theory notes Protocol mechanics and cryptography with worked examples — written alongside the practical posts, not as standalone study material
