This is a cybersecurity glossary that I created to help me study for the CompTIA Security+ exam. It is a collection of terms and definitions that I found useful while studying for the exam. I hope you find it useful as well.
This interactive glossary is designed to help cybersecurity professionals quickly reference key terms, concepts, and techniques across the field. Built with a clean, dark-themed interface, it features:
- Search functionality (Ctrl/Cmd + K)
- Filtering by category
- Expand/collapse all definitions
- Grid/list view toggle
