Security Documentation & Note-Taking

A free, practical Obsidian mini-course for documenting cybersecurity work clearly, safely, and professionally.

Good security work needs more than tools and technical knowledge. It needs clear notes, evidence, validation, decisions, and a record of what happened. This course helps you build a documentation system you can use for authorized labs, projects, findings, risk assessments, incident exercises, and portfolio work.

• How to structure a small but effective security-notes system in Obsidian
