Security Operations Labs & Threat Intelligence Notes

🟩🟦🟥🟨 🟦🟨🟥🟩 🟥🟩🟦🟨 🟨🟥🟩🟦

This repository contains structured notes, playbooks, and practical walkthroughs related to Security Operations (SOC), Threat Intelligence, and Incident Response.

The purpose of this repository is to document hands-on learning, analytical workflows, and security operations thinking through realistic, scenario-based examples. It demonstrates how security alerts are analyzed, incidents are handled, and threats are mapped and documented in operational environments.

This is a living repository and will be continuously updated as new tools, techniques, and scenarios are explored.
