Glossary of Cyber Terms and Definitions Substantially Updated

The online glossary and database of comparative definitions of key terms in cyber defence has been updated. The glossary, created and managed by the NATO Cooperative Cyber Defence Centre of Excellence, is a research tool for educators, scientists and policymakers. 

Developing a comprehensive cyber terms glossary is of key importance in enhancing awareness and fluency in cyber affairs. Over the past 30 years, the cyber domain has evolved to a global phenomenon and its presence in our everyday lives is rapidly increasing. Regardless of that, there are no common definitions for key terms – they are understood to mean different things by different nations, organisations, individuals and the academia. 

Given that there is no common language, the glossary helps to navigate in the maze of numerous definitions. It aims to provide a picture on how nations/states and different institutions interpret and approach all things cyber in their official documents. The glossary is based on definitions publicly available in English. The majority of definitions provided are from The Tallinn Manual and strategic or policy documents, such as national strategies.

As researchers and educators, the Centre experts have compiled and are constantly updating a number of research tools that any student, scholar, policy-maker, etc. will find useful and practical in their everyday work.  The NATO Cooperative Cyber Defence Centre of Excellence toolkit includes the interactive International Cyber Developments Review (INCYDER) database of the legal and policy documents adopted by international organisations working in cyber security, as well as a regularly updated comprehensive overview of national cyber defence strategies and relevant legal acts.
