Weekly Letters
BTL1 Learning Journey
Every week I publish a detailed letter documenting what I’m learning through the BTL1 certification. Each letter combines technical concepts, practical examples, and real-world applications for SOC/Blue-Team roles.
What’s in Each Letter?
- Blue Team Fundamentals: Detection engineering, log analysis, incident response, and defensive security
- Practical Examples: Scripts, runbooks, detection rules, and real-world applications
- Reflections: Challenges faced, lessons learned, and how concepts connect
