The decisions that must be made for cyber defence are often based on information that is both subjective and qualitative in nature. Objective, quantitative information can exist in the form of various measurements and metrics; however, it is not yet clear what information is needed to support the cyber defence decision-maker as the decision space for cyber defence has not been formalised. The NATO Communication and Information Agency (NCIA) Communications and Information System (CIS) Security Capability Breakdown presents a list of cyber defence capabilities and provides a useful starting point for such an analysis. As part of CIS security, cyber defence addresses the ability to safeguard the delivery and management of services in response to potential and actual malicious actions in cyberspace. In the present work, the breakdown of cyber defence capabilities is used to carry out a mission-function-task (MFT) analysis. This is accomplished by translating cyber defence capabilities into cyber defence missions and their functions, and then enumerating the tasks that would be needed to perform each function. The resulting tasks are then analysed for their information requirements in order to identify where measurements and metrics could support the decision-making needs. These results will contribute to unbiased decision-making by improving cyber defence situational awareness.
