1. Understanding CVE, CVSS, and NVD

Before diving into the comparison, let’s define these key terms in vulnerability management.

CVE (Common Vulnerabilities and Exposures): This is a list of publicly disclosed cybersecurity vulnerabilities. Each vulnerability is assigned a unique CVE ID, allowing for easy tracking and management across different platforms.
CVSS (Common Vulnerability Scoring System): This provides a standardized framework for evaluating the severity of security vulnerabilities. It helps organizations prioritize vulnerabilities and determine which ones require immediate attention.
NVD (National Vulnerability Database): Managed by NIST, the NVD is a comprehensive database synchronized with the CVE list. It enhances CVE entries with additional information, such as patch availability and severity scores, making it a valuable resource for in-depth vulnerability analysis.

2. Key Differences Between CVE and a Vulnerability Database

The main difference lies in the level of detail and functionality. CVE is essentially a list of vulnerabilities, while a vulnerability database like NVD provides enriched information.

2.1. CVE: The Foundation

Purpose: To provide a standardized naming system for vulnerabilities.
Content: Each entry includes a unique CVE ID, a brief description of the vulnerability, and references to related information.
Maintenance: Maintained by MITRE Corporation.

2.2. Vulnerability Database (e.g., NVD): The Enriched Resource

Purpose: To provide detailed information and analysis of vulnerabilities.
Content: Includes CVE ID, detailed description, CVSS scores, affected products, patch information, and references.
