Cross-domain situational awareness and collaborative working for cyber security

Enhancing situational awareness is a major goal for organisations spanning many sectors, working across many domains. An increased awareness of the state of environments enables improved decision-making. Endsley's model of situational awareness has improved the understanding for the design of decision-support systems. This paper presents and discusses a theoretical model to extend this to cross-domain working to influence the design of future collaborative systems. A use-case is discussed within a military context of the use of this model for cross-domain working between an operational-domain and cyber security-domain.
