Original Post: Detailed Technical Overview of Exploit Prediction Scoring System (EPSS) | by Nitin Nayar | Jul, 2024
The Exploit Prediction Scoring System (EPSS) is a data-driven framework designed to predict the likelihood that specific software vulnerabilities will be exploited in real-world situations. Managed by the Forum of Incident Response and Security Teams (FIRST), EPSS helps cybersecurity professionals prioritize remediation efforts more effectively, complementing traditional systems like the Common Vulnerability Scoring System (CVSS). EPSS uses diverse data sources and machine learning to analyze over 1,000 variables impacting exploitability, offering dynamic and highly accurate predictions. It integrates seamlessly into existing vulnerability management processes, helping organizations allocate resources efficiently to protect against emerging threats. Despite its benefits, implementing EPSS requires significant investment in data analysis and machine learning expertise, and its governance remains somewhat opaque. As an open-source initiative, EPSS evolves through community-driven innovation to enhance global cybersecurity practices.
