Black Hat via YouTube

Overview

This course aims to help participants understand the limitations of using the Common Vulnerability Scoring System (CVSS) as a risk metric for vulnerabilities and a prioritization metric for patching policies. By analyzing real attack data, the course demonstrates that relying solely on CVSS scores can lead to significant over-investment in patching. The teaching method includes practical examples, case studies, and statistical analysis to illustrate the inefficiencies of the CVSS approach. The course is designed for cybersecurity professionals, risk analysts, and individuals involved in vulnerability management within organizations.
