There have been a lot of serious discussions by seniors in the cyber community about definitions and resources containing them.
This labor of love by Robert Morgus is an ongoing effort to establish a community resource for the definitions in the global cyber world.
I put together a pretty comprehensive and searchable database of definitions, mostly pulled from national strategy documents (US and elsewhere). Initially put together for the OSCE’s CBM process. The interface could use a facelift, but it’s operable nonetheless.
“This website houses over 400 cyber and information security related definitions from around the world and we are constantly looking to expand and update our database. Use the search bar below to explore the database or download and browse the data by clicking the link at the top of the page. If you know of a definition that we don’t have but should, please Submit Definitions to us.”
