Purpose of CYDEF
CYDEF aims to disseminate information, share awareness, and establish collaboration.
Dissemination of information means gathering experts and knowledgeable people with various experiences and knowhow, and providing a forum for them to present their opinions. This allows us to come into contact with information to which we are not usually exposed, and to obtain hints for solving everyday problems.
Sharing awareness is about collective perceptions and gaining a foundation of understanding through presentations. This allows us to understand the common threats and work together to address them.
Establishing collaboration means understanding each other and building common ground through presentations, allowing us to cooperate on common issues.
While listening to the discussions of experts and specialists worldwide, we hope to build a framework for mutual understanding and cooperation by presenting similar issues and approaches from different countries and positions.
