Which scoring system should be used to compare vulnerabilities based on exploitability and remediation difficulty?

The Common Vulnerability Scoring System (CVSS) is specifically designed to assess and quantify the severity of vulnerabilities in software and hardware systems. It provides a systematic method for evaluating vulnerabilities based on a variety of factors, including exploitability and remediation difficulty. This scoring system uses a range of metrics to produce a score that allows organizations to prioritize their responses to vulnerabilities more effectively.

CVSS scores consider aspects such as the ease of exploitability (how easily a vulnerability can be exploited) and the impact on the system if exploited. This makes it an ideal choice for comparing vulnerabilities, as it provides a standardized way to measure risk and prioritize remediation efforts based on those risks. Using CVSS allows security teams to communicate clearly about vulnerabilities and understand their potential impact on their systems, aiding in decision-making regarding resource allocation for remediation efforts.

Other options like SCAP, CWE, and OWASP serve different purposes within the realm of security and do not provide a direct scoring mechanism for exploitability and remediation difficulty as CVSS does. SCAP is more focused on discovering vulnerabilities and compliance, CWE lists known software weaknesses, and OWASP provides guidelines and resources for web application security rather than a scoring system for vulnerabilities.
