This skill automates the process of vulnerability prioritization by querying the FIRST Exploit Prediction Scoring System (EPSS) API. It calculates the real-world probability of a CVE being exploited within 30 days, providing a crucial risk metric that surpasses traditional CVSS severity scoring. Use it for risk-based vulnerability management, allowing security teams to efficiently triage and remediate the most actively threatened vulnerabilities first.

This skill provides a comprehensive framework for vulnerability prioritization by combining three crucial data points: CISA's Known Exploited Vulnerabilities (KEV) catalog (confirming real-world exploitation evidence), EPSS scores (predicting exploitation probability), and CVSS metrics (assessing intrinsic severity). It builds a multi-factor prioritization engine to determine the most critical CVEs for immediate remediation, assisting security teams in managing large vulnerability backlogs efficiently.

This skill guides the systematic process of mitigating endpoint vulnerabilities. It involves calculating a comprehensive risk score by combining CVSS, EPSS, and CISA KEV data to prioritize findings. The workflow covers deployment of patches via platforms like WSUS/SCCM/Intune, applying necessary configuration changes, handling zero-day workarounds, and validating the fix to ensure endpoint compliance and system security.

This skill provides a comprehensive guide to the Common Vulnerability Scoring System (CVSS v4.0), the industry standard for assessing vulnerability severity. It teaches users how to calculate CVSS scores using Base, Threat, and Environmental metrics, and crucially, how to integrate real-world context like EPSS scores and CISA KEV listings for advanced, actionable risk prioritization in security operations.

A structured methodological framework for prioritizing vulnerabilities beyond raw CVSS scores. It utilizes CISA’s SSVC model, integrating real-time data like exploitation status (CISA KEV), EPSS scores, and technical impact to assign actionable outcomes: Track, Track*, Attend, or Act. Essential for mature security operations and remediation planning.
