We propose an approach to ranking computer network assets based on their criticality to an organization’s current operations and business functions and their strategic importance to the organization’s adversaries. An asset’s criticality is a measure of its current importance to the organization, while an adversary’s interest in the asset is a measure of its current importance to the adversary and, therefore, its future importance to the organization. We adapt techniques from existing work on asset criticality for use by a national defence organization. We also adapt these techniques to produce an adversarial interest score. We propose solutions for calculating these scores at the asset and the unit level and hybrid variants of both. We discuss options for combining asset criticality and adversarial interest scores to produce a list of assets or units ranked in order of their importance to the organization. The adversarial interest score can be used as an input to course-of-action recommendation algorithms. The combined ranked list of assets can be used by cyber defenders to prioritize the protection of assets within an organization.
