# Cyber Security Acronyms and Terms



Curated list of acronyms and terms related to cyber security landscape including industry, open source and non-profit organizations (Basically any concept that has anything to do with security practices around the cloud, applications, assets, services, kubernetes and containers).



This glossary classifies and explains security terms to make them understandable beyond the 'buzzoword'.



Any contribution will be more than welcome.
