What does the Forum of Incident Response and Security Teams provide that generates a metric score from 0 to 10?

The Forum of Incident Response and Security Teams (FIRST) provides the Common Vulnerability Scoring System (CVSS), which generates a metric score ranging from 0 to 10. CVSS is a standardized framework for assessing the severity of security vulnerabilities in software and systems. This scoring system helps organizations prioritize their responses and remediation efforts based on the potential impact and exploitability of the vulnerability.

The metric score is derived from several factors, including the intrinsic characteristics of the vulnerability itself and its potential impact on the system once exploited. By having a numerical score, CVSS allows teams to compare vulnerabilities consistently and make informed decisions about risk management.

In contrast, the other options refer to different aspects of cybersecurity. For example, SPF (Sender Policy Framework) is related to email security to prevent spoofing, CTI (Cyber Threat Intelligence) involves gathering and analyzing information about threats, and APT (Advanced Persistent Threat) denotes a type of cyber attack that is characterized by a high level of sophistication and persistence. None of these provide a standardized metric score like CVSS does.
