What is a CVE? Explaining the Importance and History of CVEs

The Common Vulnerability Exposure (CVE) is a standard for tagging and tracking vulnerabilities. It’s a system that provides researchers with a universal method of identifying security vulnerabilities and tracking them over time. This helps software vendors, users, and others track the state of specific security issues in code. We have discussed various types of risk before, such as operational risk and control risk. The CVE is another type of risk but one that has to do specifically with the potential for software to be vulnerable to cyberattacks. This article explains what a CVE is, its history, how it works, and why it’s important for your business’s cyber risk management strategy.
What Is a CVE?
A CVE is a unique identifier used to track vulnerabilities in software and other types of products. If a researcher finds a vulnerability that’s been found in the past, they can use the CVE to track it and prevent the same error from being misreported as a new one. The CVE is run by the MITRE Corporation, a nonprofit organization that runs many standards and tracking systems for the federal government and private sector. There are three important points to know about CVEs: They are standardized, they are unique, and they are retroactive. In other words, all CVEs follow a specific format to ensure consistency, every CVE is unique, and every CVE can be applied to past vulnerabilities. This is useful for tracking vulnerabilities over time and for comparing the severity of different vulnerabilities.
The Importance of CVEs for Risk Management
The main use of CVEs is for risk management and vulnerability identification. The CVE database acts as a database of vulnerabilities that has been growing since 1999, when it was founded. This means that CVEs can be applied retroactively, so vulnerabilities that have been discovered and patched can be tracked with the CVE database. This is important because it allows organizations to track their vulnerabilities over time. This is important because it allows organizations to track their vulnerabilities over time. This means they can identify trends in their cybersecurity posture and be aware of issues that need attention. Additionally, CVEs allow organizations to track and compare the severity of vulnerabilities across industries, types of systems, and more. This allows for better prioritization of where to focus efforts and resources.
What is CVE-Based Scoping?
CVE-based scoping is a methodology used by organizations to scale the severity of a vulnerability based on its CVE identifier. This means that if a vulnerability is given a certain CVE identifier, it will be given a predetermined severity rating. This allows organizations to have a standardized approach to scoping and helps with both consistency and comparison of vulnerabilities. This is helpful because it allows organizations to have a clear set of rules for how they should be classifying and prioritizing their vulnerabilities.
History of the CVE
The CVE has been operating since 1999. That year, the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) partnered with MITRE, a nonprofit research and development organization, to create a standardized and consistent way to track vulnerabilities. This was done to address the problem of inconsistent and unclear ways of identifying vulnerabilities. Before the CVE, researchers reported vulnerabilities in a variety of different ways that made it difficult to track and compare them over time. The goal of the CVE was to provide a consistent and standardized method for identifying vulnerabilities and tracking them over time.
How Does a CVE Work?
We’ve discussed the importance and history of CVEs, but how does that method work? Let’s break down how the CVE works for researchers, software vendors, and users. Researchers - If you are a researcher and have discovered a new vulnerability, you report it to a tracking service like the MITRE CVE. You do this by submitting a unique identifier (the CVE) and details about the vulnerability. This includes information like what software the vulnerability exists in, how severe it is, and more. If your submission has a unique identifier (the CVE), you’re able to track the vulnerability over time and compare it to similar vulnerabilities. This means you can see if there are any patches or fixes for the vulnerability and see if vulnerabilities are being exploited in the wild. Software Vendors - If you work for a software vendor, you use the CVE to track vulnerabilities that have been reported to you. This allows you to keep track of which vulnerabilities are being reported and how severe they are. It also allows you to prioritize which issues to fix first based on their severity and which software the vulnerability exists in. Users - If you’re a user of software, you can also use the CVE to report vulnerabilities that you find. This can be done by entering the CVE into a vulnerability search engine and seeing what information comes up. This allows you to see if a vulnerability has already been reported and if it has been fixed. You can also use the CVE to see which software the vulnerability exists in and get more information on the vulnerability.
The CVE is a standardized method of tracking vulnerabilities and identifying risks over time.

The CVE has been operating since 1999 and is run by the MITRE Corporation. It is important for risk management, vulnerability identification, and cybersecurity strategy. If a researcher finds a vulnerability, they report it to a tracking service like the CVE. This allows them to track the vulnerability over time and compare it to other vulnerabilities.
