What is CVE in Cyber Security?

In this article, you will learn what is CVE in Cyber Security, why it is important, how to find the CVE identifier for a vulnerability, and common mistakes in using CVE.

Introduction

In the world of cyber security, malware, viruses, and hacking are all too common. Attacks on businesses and individuals happen almost every day. Companies need to be able to recognize when they are being attacked so they can take action quickly and effectively. In response to this need for a universal identity standard that identifies cyber vulnerabilities and threats, the Common Vulnerability Exposure (CVE) was created.

What is CVE in Cyber Security?

A CVE is a list of universal identifiers for various known cybersecurity threats with detailed information about their characteristics and effects. This list is used by businesses, governments, and individuals to identify a threat and create a plan of action.

It’s important to have a universal identifier because, in the realm of cybersecurity, threats are constantly evolving. A common vulnerability exposure list is important because it allows organizations to identify threats quickly, share information about how to handle the threat, and create better protective measures for cybersecurity.

The standard is used by both public and private organizations to identify threats, track vulnerabilities, and create a system of standardization for cyber threat response.

Why Does Having a Common Vulnerability Exposure List Matter?

A common vulnerability exposure list is important because it allows organizations to identify threats quickly, share information about handling them, and create better protective measures for cybersecurity.

Those on the list are often considered critical vulnerabilities that must be addressed as soon as possible. The more commonly found the vulnerability, the higher it will be ranked on the list. This allows organizations to prioritize their spending. When cyber attacks happen, organizations need to have a system in place for fast and effective response.

Having a standard that can be used by all organizations for identification, response, and follow-up allows for quick and effective action in the face of cyber threats. The standard can be used not just by businesses, but also by individuals, organizations, and governments.

How to Find a CVE Identifier for a Vulnerability?

Generally, finding a CVE identifier for a vulnerability is easy. The first step is to determine which of the groups the vulnerability falls under. There are 15 main groups of vulnerabilities, including software, hardware, network, web application, etc. Within each group, there are several specific vulnerability types.

Examples include remote code execution, denial of service, etc. Once you have determined the group and type of vulnerability, you can search the CVE website to see if it already has an identifier. If it does not, you can submit a request to have it added to the list.

Common Mistakes When Using the CVE in Cyber Security

Knowing how to use the CVE in cyber security is important, but to make sure you are using it correctly, there are a few mistakes to avoid.

  • Mistake #1: Confusing the CVE for a Solution - The first mistake is confusing the CVE for a solution. It is important to remember that the CVE is a list of vulnerabilities with detailed information about them. It does not offer a solution for how to fix those vulnerabilities.
  • Mistake #2: Using the CVE Identifier as the Name of the Vulnerability - Another common mistake is using the CVE identifier as the name of the vulnerability. For example, you can use the CVE identifier “CVE-2018-15103” to refer to a specific remote code execution vulnerability. However, it is important to note that the full name of the vulnerability is Remote Code Execution in Linux Kernel.
  • Mistake #3: Not Reading the Description of the CVE - When you use a CVE identifier, it is important to read the description to understand the context. Not only will this help you remember what the vulnerability is and why it is important, but it will also allow you to communicate more effectively with others who use the CVE.

Conclusion

The CVE is a list of universal identifiers for various known cybersecurity threats with detailed information about their characteristics and effects. This list is used by businesses, governments, and individuals to identify a threat and create a plan of action. It’s essential to have a universal identifier because, in the realm of cybersecurity, threats are constantly evolving.
