Advisory Feeds: National Vulnerability Database (NVD), Open Source Vulnerabilities (OSV), Known Exploited Vulnerabilities (KEV), Exploit Prediction Scoring System (EPSS) and MITRE ATT&CK

About this course

A working guide to the twelve advisory feeds behind Safeguard's vulnerability and supply chain intelligence: where each feed's data comes from, its refresh cadence and its blind spots, and how Common Vulnerabilities and Exposures, GitHub Security Advisories and Open Source Vulnerabilities identifiers reconcile when they disagree. You will combine Known Exploited Vulnerabilities status, Exploit Prediction Scoring System probability and public exploit availability into one defensible priority order, then bring in supply chain trust and MITRE ATT&CK context through worked, cross-feed reconciliation scenarios.
