The CPE Dictionary is hosted and maintained at NIST, may be used by nongovernmental organizations on a voluntary basis, and is not subject to copyright in the United States. [ 1 ] CPE identifiers are commonly used to search for Common Vulnerabilities and Exposures (CVEs) that affect the identified product.
A vulnerability database (VDB) is a platform aimed at collecting, maintaining, and disseminating information about discovered computer security vulnerabilities.The database will customarily describe the identified vulnerability, assess the potential impact on affected systems, and any workarounds or updates to mitigate the issue.
As of November 2024, there are more than 240,000 vulnerabilities [1] catalogued in the Common Vulnerabilities and Exposures (CVE) database. A vulnerability is initiated when it is introduced into hardware or software. It becomes active and exploitable when the software or hardware containing the vulnerability is running.
The Common Vulnerability Scoring System (CVSS) is a technical standard for assessing the severity of vulnerabilities in computing systems. Scores are calculated based on a formula with several metrics that approximate ease and impact of an exploit.
Common Weakness Enumeration (CWE) logo. The Common Weakness Enumeration (CWE) is a category system for hardware and software weaknesses and vulnerabilities.It is sustained by a community project with the goals of understanding flaws in software and hardware and creating automated tools that can be used to identify, fix, and prevent those flaws.

The cost and complexity of the framework has resulted in bills from both houses of Congress that direct NIST to create Cybersecurity Framework guides that are more accessible to small and medium businesses. [11] [12] Here are the functions and categories, along with their unique identifiers and definitions, as stated in the framework document. [13]
