Security Glossary

A searchable reference of 100+ cybersecurity terms and acronyms, written in plain language for SOC analysts, penetration testers, and DFIR practitioners who need a fast, accurate definition without digging through a vendor whitepaper. Every entry includes the full term, its common abbreviation, and a short, precise definition — covering general security concepts, malware, networking, SOC operations, forensics, cloud, and cryptography. Filter by category or jump straight to a letter using the A–Z index. Built for quick lookups during an interview, a report write-up, or while reading a threat advisory — and it works completely offline once loaded.
