Abstract
Mechanisms are provided for identifying vulnerability chains in a computing system. Computer system vulnerability characteristics for a plurality of computer system vulnerabilities from a vulnerability registry are retrieved. For each vulnerability, a threat score is calculated indicating a level of risk of the vulnerability to security of the computing system. Based on the vulnerability characteristics and the threat score, a directed acyclic graph (DAG) data structure is generated having a plurality of vulnerability chains, each vulnerability chain having a plurality of vulnerabilities, represented as nodes of the DAG, linked to each other from a root node to a terminating node. Links of the DAG have weights corresponding to a function of the threat scores of the nodes directly connected by the link. A graphical representation of the DAG is generated that depicts the weights of the links to thereby represent relative threat of the vulnerabilities linked by the links.
