Leveraging EPSS, CVSS, and KEV for Comprehensive Risk Management & Prioritization

In cybersecurity, managing and prioritizing vulnerabilities is crucial for protecting digital assets. The Exploit Prediction Scoring System (EPSS), the Common Vulnerability Scoring System (CVSS), and the Known Exploited Vulnerabilities (KEV) catalog are three risk scoring systems that help in this process. EPSS estimates the likelihood of a vulnerability being exploited, while CVSS provides an exhaustive assessment of a vulnerability's potential impact. The KEV catalog maintains information on vulnerabilities that have been exploited in real-world attacks. Arnica's approach to vulnerability management combines these systems with business importance and patch effectiveness to provide a comprehensive framework for prioritizing vulnerabilities effectively.
