Automated cybersecurity vulnerability prioritization

Abstract

Implementations include a computer-implemented method comprising: obtaining data representing observed conditions in an enterprise network, each observed condition being associated with at least one cybersecurity issue, a cybersecurity issue comprising one of (i) a vulnerability comprising an instance of a vulnerable condition or (ii) a weakness that is likely to cause a vulnerability to occur; using a plurality of exploitation prediction models to determine probabilities of exploitation of the cybersecurity issues associated with the observed conditions in the enterprise network, wherein the plurality of exploitation prediction models are trained using a knowledge mesh generated using data from cybersecurity repositories; assigning a priority ranking to each of the observed conditions in the enterprise network based on the respective probabilities of exploitation for the cybersecurity issues associated with the observed conditions; and performing one or more actions to mitigate the observed conditions in the enterprise network based on the priority rankings.
