CVE Severity: Risk-Based Prioritization

In large networks, security teams receive hundreds of CVE notifications every day. It is resource-intensive to patch all vulnerabilities at once and immediately. CVE Severity is based on the CVSS (Common Vulnerability Scoring System) system, which measures the risk of vulnerabilities from 0.0 to 10.0, and serves as a compass for teams to prioritize which threats to address.

Severity Levels and Response Strategies

The CVSS framework categorizes vulnerabilities into four different severity levels. Each level requires a different response time:

Critical Level (CVSS 9.0 – 10.0)

Characteristics: Can be exploited over the Internet, without user interaction, and without requiring any special privileges. Allows for full system control (Remote Code Execution).
