📖 About

This repository is my personal cybersecurity knowledge base where I document everything I learn while studying and practicing cybersecurity.

Instead of simply completing labs, I break every topic into detailed notes with explanations, screenshots, practical examples, commands, and real-world concepts.

The goal is simple:

• Build a second brain for cybersecurity.
• Help beginners learn faster.
• Track my own cybersecurity journey.
• Create a practical reference for future SOC and DFIR work.
