Framework for Computing Assurance Measurements based on Evolving Resilience Metrics (FRAMER)

As command and control, doctrine, and tactics evolve with the cyber network at its core, mission-critical tasks increasingly rely on the integrity and responsiveness of the network and other cyber assets. While this trend has acted as a tremendous force multiplier and OPTEMPO accelerator, two major concerns arise: (1) network usage demands will soon outstrip the capabilities of a resource-constrained network (e.g., download requests for UAV data exceeding available bandwidth); and (2) the growing capabilities of adversaries to wage cyber warfare will disrupt networks. To assess mission assurance based on the resilience and criticality of cyber assets, we propose to design and demonstrate a Framework for Computing Assurance Measurements based on Evolving Resilience Metrics (FRAMER) that measures mission assurance through cyber asset resilience and criticality metrics. FRAMER introduces a new set of criticality and resilience metrics by maintaining a constantly evolving set of mappings between cyber assets and prioritized mission elements. Together, the mappings and relationships drive the derivation of criticality and resilience measures for each cyber asset. FRAMER assesses mission assurance for each mission by aggregating the criticality and resilience of each cyber asset mapped to a collection of missions.
