Toward global cybersecurity collaboration: Cybersecurity operation activity model

摘要

The importance of communication and collaboration beyond organizational borders is increasingly recognized with regard to maintaining cybersecurity. Yet organizations still face difficulties communicating and collaborating with external parties. Among these difficulties is the absence of a common vocabulary, as organizations do not always share the same terminology in describing operations, and this consumes unnecessary time and can lead to miscommunication. This paper addresses the problem by introducing a cyberse-curity operation activity model that provides the foundation for defining such vocabulary. The model also facilitates understanding and review of cybersecurity operations and their associated activities. This paper demonstrates the model's usability by visualizing the domains of cybersecurity operations and services and concludes that the model has sufficient usability as a foundation for building vocabulary and as a tool for visualizing cybersecurity issues, which will help expedite communication beyond organizational borders.
