A method of risk management across a mission support network is provided, including identifying a mission of the mission support network, and identifying, by a computer processor, assets of the mission support network. The assets include a mission asset to support the mission and a support asset to provide support to the mission asset. Each of the assets is characterized by a criticality index value to measure how important the asset is to a performance of the mission, and a vulnerability index value to measure a vulnerability of the asset to a threat.
