What is CVE in Cyber Security? The Ultimate Guide for IT Professionals

What is CVE in Cyber Security?

Diving into the world of cybersecurity, one term stands out: This is a question that is often asked in the IT departments across the globe; CVE stands for Common Vulnerabilities and Exposures in Cyber Security.

In the vast ocean of cyber threats, CVEs are a beacon that helps to find the right direction to a safer cyber space. They are common vulnerabilities that are publicly disclosed and each of the vulnerabilities has a CVE identifier. These IDs are assigned by organizations that are allowed to assign such IDs known as CVE Numbering Authorities (CNAs).

It is crucial to point out that CVEs are extremely valuable. For instance, in the year 2022 alone, 26,448 software security flaws were recorded and by the first week of 2024, 612 new IT security vulnerabilities were identified. These statistics show how CVEs are vital in the war against cyber threats.

Definition of CVE (Common Vulnerabilities and Exposures)

Now, let us get to the core of our topic, “What is CVE in Cyber Security?”; CVE means Common Vulnerabilities and Exposures.

CVE is a dictionary of publicly known information security vulnerabilities. Every vulnerability on this list is assigned a specific number, which is called CVE ID. This ID enables the exchange of information between the different vulnerability capabilities, that is, tools, databases, and services.

For example, there is CVE-2021-34527, a relatively new vulnerability that is associated with the Windows Print Spooler, or “PrintNightmare”. This vulnerability lets the potential attackers run any code on the system and gain root access.

The CVE list is managed by MITRE Corporation, a not-for-profit organization that runs several federally funded research and development centers in the United States of America.

The CVE program that was initiated in the year 1999 has been a valuable asset in the sphere of cybersecurity as it offers a common language for the description of vulnerabilities. It helps IT personnel to protect their systems by allowing them to monitor, fix, and prevent cyber threats.

Thus, knowing the meaning of the term ‘CVE in Cyber Security’ is a significant step towards enhancing the cybersecurity of your organization. More information is coming in the subsequent parts of this guide so keep on reading.

The role of CVE in cyber security

Thus, when asking the question “What is CVE in cyber security?”, we are getting to the very essence of the matter in cyber defense. CVEs are employed worldwide for the management of security of IT systems and are hence very crucial.

CVEs provide a method of assigning a name and a classification to the vulnerabilities so that the organizations can share information about them and the measures they have taken. It is a means through which the cybersecurity experts can describe the level of risk and the extent of the system’s openness.

Over 26000 vulnerabilities were reported in the year 2023 alone. This figure shows how severe the issue is that IT staff face in the process of protecting their systems. All of these are the areas that the hackers can exploit to get into a system.

For example, there is the Log4j vulnerability (CVE-2021-44228) that affected many service providers including AWS, Cloudflare, and Twitter. Apache Log4j is a Java based logging framework which is widely used and this is a clear indication of how a single CVE can impact many.

CVEs also play a role in the evolution of patches and updates. When a vulnerability is discovered, the first thing that developers do is to attempt to come up with a solution. It is important to apply the patches as soon as possible since the mean time to remediation (MTTR) is 58 days. This period weakens systems and makes them prone to be attacked.

Understanding the CVE Identifier

Diving into the world of cyber security, one term stands out: The abbreviation of the above mentioned is CVE. Now, what is CVE in cyber security? IT professionals should be familiar with CVE, or Common Vulnerabilities and Exposures.

Explanation of the structure of a CVE Identifier

A CVE Identifier is also referred to as CVE ID is a unique number that is given to every publicly known cybersecurity weakness. The format of a CVE ID is quite simple and does not change from one ID to another. It is denoted by CVE- and then the year in which the vulnerability was assigned and a unique number. Let’s take an example of the code “CVE-2022-1234”.

The year part of the CVE ID is the year in which the ID was assigned to the vulnerability and not the year when the vulnerability was discovered. This is crucial in an effort to be in a position to establish the time frame of a vulnerability’s life cycle.

The sequential number is given to each vulnerability and it is a four or more digits number. This number does not tell anything about the vulnerability in particular. It is just a method of distinguishing one vulnerability from another.

The task of assigning CVE IDs is done by CVE Numbering Authorities (CNAs) that include international vendors and researchers. These CNAs provide the CVE ID when a potential vulnerability of a cybersecurity threat is identified.

Understanding the structure of a CVE Identifier is important in explaining what CVE is in cyber security. It assists cybersecurity professionals to describe the vulnerabilities in a standard format and, therefore, improve the communication.

CVE and IT Professionals

In the constantly changing world of threats in cyberspace, CVE is an important concept. They offer the IT personnel a framework that can be used to assess and address risks. Current statistics show that there are more and more CVEs, which means that it is crucial to be aware of the situation.

Why IT professionals need to understand CVE

In this case, IT professionals must have an understanding of CVE, or Common Vulnerabilities and Exposures. This knowledge enables them to avoid any potential risks and protect their systems to the optimum level.

First of all, CVEs are a source of information on possible threats to security. It provides information on the weaknesses that the hacker may use. Thus, IT professionals can use the latest CVEs to prevent such vulnerabilities and improve the security of their systems.

Secondly, knowledge of CVEs assists in determining where to focus the security measures. Not all the vulnerabilities are of the same level of risk. Each CVE has a severity rating which will help in identifying the extent of the damage that can be done by the vulnerability. This makes it easier for IT professionals to concentrate their attention on the areas that require their attention most.

Finally, CVEs are globally accepted. This is because they offer a way of describing security risks that can be easily understood by IT personnel hence improving on the communication and cooperation between the two.

To this end, knowledge is the best weapon in the field of cybersecurity. Hence, the knowledge of what CVE in cyber security entails is not only helpful but crucial for IT personnel. It empowers them with the knowledge that they require to protect their systems and information.

The impact of CVE on IT security practices

It is therefore important to explain what CVE in cyber security means to IT professionals. The effects of CVEs on IT security practices are far-reaching and complex in nature.

First, the number of new vulnerabilities has grown tremendously. In 2022, the threat actors targeted older software flaws more than the recently known ones. This is a clear indication that patching and updating of systems should be done as soon as possible.

Secondly, the increase in CVEs has also resulted in the increase in the number of high risk vulnerabilities that are being exploited by the threat actors and ransomware gangs. In 2023, over half of the 206 high-risk vulnerabilities tracked were exploited to gain access into systems. This underlines the fact that there is a need for strong and effective cybersecurity strategies.

Thirdly, the mean time to remediation (MTTR) is about 58 days. This means that organizations are making efforts to close gaps but there is still much that can be done.

Finally, let us look at an example. A large online shopping website found a severe bug in the payment gateway module. They were able to easily find the vulnerability in the CVE database and then release a patch to address it. This example shows how CVEs can be useful in enabling organizations to quickly and appropriately address security incidents.
