Common Vulnerabilities and Exposures (often called CVEs) are a publicly accessible catalog of known security vulnerabilities in software and hardwareEach vulnerability is assigned a unique CVE ID, which helps organizations track, share information about, and prioritize fixes for these vulnerabilities. 

What Should I Know About CVEs?

  • Publicly accessible catalog: CVEs are maintained by the MITRE Corporation and are available to the public.
  • Standardized IDs: Each vulnerability gets a unique CVE ID (e.g., CVE-2024-12345).
  • Information hub: CVEs provide a brief description of the vulnerability, references to related reports and advisories, and information about the affected software or hardware.
  • Focus on vulnerability details: CVEs focus on the vulnerability itself, not the severity, impact, or fixes. 

Vulnerability Assessments

A great way to discover some of the unique vulnerabilities that small and medium-sized businesses (SMBs) face is to get a vulnerability scan. These are fast, easy and affordable, and can easily be ordered.

Why are CVEs important?

  • Facilitates communication: CVE IDs provide a common language for security professionals to discuss and share information about vulnerabilities. 
  • Prioritizes fixes: CVEs help organizations understand which vulnerabilities are most important to fix based on severity and impact. 
  • Enables vulnerability management: CVEs are used by security tools and services to scan for vulnerabilities, generate alerts, and manage patches. 

How do CVEs work?

  • CVE Numbering Authorities (CNAs): CNAs are organizations authorized to assign CVE IDs.
  • Bug bounty programs: Many companies offer rewards for reporting vulnerabilities, which can lead to CVE assignment.
  • Reporting and submission: When a new vulnerability is identified, it’s submitted to a CNA for review and evaluation.
  • CVE record creation: The CNA then creates a CVE record, which includes details about the vulnerability, affected products, and references.
  • Public release: The CVE record is then made publicly available on the CVE list.
