Which designation is NOT used when categorizing vulnerabilities?

The designation that is not used when categorizing vulnerabilities is "Significant." Organizations, particularly those involved in cybersecurity and risk management, typically categorize vulnerabilities using a framework that includes terms like Critical, High, and Moderate.

"Critical" vulnerabilities represent the most severe issues that could lead to significant harm or loss if exploited. "High" vulnerabilities pose significant risks but may not be as urgent as critical ones. "Moderate" vulnerabilities are those that might require attention but are not as severe as the higher categories.

The term "Significant," however, does not align with standard vulnerability classification systems commonly used. This helps maintain a clear and consistent understanding of risks and prioritization in addressing vulnerabilities within a security framework.
