Security Practitioner
Offense-informed defense: crypto, web vulns, detection and incident response.
- 1Cybersecurity Fundamentals for PractitionersThink like an operator: threat-model your systems, walk the attack lifecycle, harden and instrument hosts, and run your first incident — with real commands and real pitfalls.
- 2Web Application Security in PracticeThe OWASP landscape from the defender's bench: XSS, CSRF, SSRF, injection, broken auth, and deserialization — exploit, fix, and the headers that hold.
- 3Applied Cryptography for EngineersHash, encrypt, sign, and manage keys like a builder — the primitives production systems actually use, and the misuse patterns that quietly break them.
- 4Detection EngineeringBuild detections that fire on attackers, not noise: the telemetry that matters, Sigma-style rule craft, ATT&CK mapping that stays honest, false-positive tuning, atomic tests, and real coverage metrics.
- 5Incident Response & Digital ForensicsRespond like a professional: triage and scope intrusions, preserve evidence, work memory and disk forensics, build the timeline, contain and eradicate, and write the postmortem that prevents the next breach.
