A computer-implemented method for discovering network attack paths is provided. The method includes a computer generating scoring system results based on analysis of vulnerabilities of nodes in a network configuration. The method also includes the computer applying Bayesian probability to the scoring system results and selected qualitative risk attributes wherein output accounts for dependencies between vulnerabilities of the nodes. The method also includes the computer applying a weighted-average algorithm to the output yielding at least one ranking of nodes in order of likelihood of targeting by an external attacker.
