Methods, systems, and computer program products are provided for improving a network by modeling control strength of network nodes. Design and implementation (DIS) scores are calculated for each of a plurality of nodes. An initial strength (InitCS) corresponding to any control performed by the node is determined. n-subgraphs are generated based on a network graph. For each node in the subgraph of the n-subgraphs, a modified control strength (ModCS) corresponding to a combination of the InitCS, a weakening factor derived from a combination of a ModCS of a plurality of upstream nodes, and a reliance coefficient (RC) of each node-to-node relationship of the plurality of upstream nodes, is determined. A risk mitigation process is performed based, in part, on any one or a combination of: DIS, InitCS and ModCS.
