In this episode, the FIRST Podcasters interview Jay Jacobs, who is a co-chair of the Exploit Prediction Scoring System Special Interest Group (EPSS SIG) and one of the founders of the Cyentia Institute. Evolving over the last year and a half, EPSS works to gather as much data as possible on vulnerabilities and look for indicators that something will be exploited in the future. Scores are updated daily with new evidences gained on potential exploitations. It is nearly impossible for companies to keep up with all their vulnerabilities, so prioritization is a must. Exploitation activity helps narrow down what’s important. The EPSS SIG is constantly updating and improving models to close gaps.
