What is Vulnerability Management?

Vulnerability management is the proactive and continuous process of identifying, assessing, and mitigating potential security weaknesses across computer systems, networks, and enterprise applications. 

It involves using vulnerability tools and processes to detect vulnerabilities, prioritize risks based on threat intelligence and business operations, and implement patches or remediation measures to keep systems safe from cyberattacks and data breaches.

By staying vigilant and addressing vulnerabilities, companies can reduce their overall risk exposure and protect against potential threats. 

Vulnerability management is an essential component of any security program, helping to prevent attacks and minimize damage in the event of a security breach. 

It requires ongoing effort to keep up with threats and changes in the IT environment, making it an important aspect of maintaining a secure infrastructure.

What Are the Differences Between a Vulnerability, a Risk, and a Threat?

What Are the Differences Between a Vulnerability a Risk and a Threat

Before we go further into vulnerability management, you need to understand these three cybersecurity terms that are often used together to define scenarios. They might seem the same but have very different concepts. 


A vulnerability refers to a weakness, flaw, or deficiency in an asset’s design, implementation, or operation that could potentially be exploited by a threat. It represents a potential entry point for attackers to compromise the confidentiality, integrity, or availability of the asset. Vulnerabilities can manifest in various forms, including technical flaws in software or hardware, human errors, or process inadequacies.

Types of Vulnerabilities:

These are the types of vulnerabilities that you might encounter. 

  • Technical vulnerabilities: Bugs in code, errors in hardware or software.

  • Human vulnerabilities: Errors or oversights by employees, such as falling for phishing attacks.

  • Process vulnerabilities: Weaknesses in organizational procedures or controls.


A threat is any circumstance, event, or entity with the potential to exploit a vulnerability and cause harm to an asset. Threats encompass a wide range of malicious activities, including cyberattacks, data breaches, malware infections, and physical security breaches. They can be intentional or unintentional, human-made or natural, and can originate from internal or external sources.

Types of Threats:

These are the types of threats that you might encounter. 

  • Intentional threats: Malicious acts perpetrated with the intent to cause harm, such as cyberattacks and insider threats.

  • Unintentional threats: Accidental actions or errors that result in security breaches, such as misconfigurations or negligence.

  • Natural threats: Disruptions caused by natural disasters, environmental factors, or other uncontrollable events.


Risk represents the potential for loss or harm to an asset resulting from the exploitation of vulnerabilities by threats. It combines the probability of a threat occurring with the potential impact or consequences of that threat. Risk assessment involves evaluating the likelihood of a threat exploiting a vulnerability and the magnitude of the resulting impact on the organization.

Types of risks:

These are the types of threats that you might encounter. 

  • External risks: Threats originating from outside the organization, such as cyberattacks, phishing attempts, or denial-of-service attacks.

  • Internal risks: Threats arising from within the organization, including insider threats, employee errors, or unauthorized access.

Risk Calculation Formula

In case of instances where the costs of the assets and the probability of a threat can be evaluated, you can use the formula below to calculate the risks to your infrastructure. 

Risk = Probability of threat occurrence × Cost to the asset owner

How are Vulnerabilities Ranked and Categorized?

Vulnerabilities are ranked and categorized based on their severity and potential impact on systems and data. This process involves assessing various factors to determine the level of risk posed by each vulnerability. Here’s how vulnerabilities are ranked and categorized:

Severity Assessment

Vulnerabilities undergo an initial assessment for severity, taking into account the potential damage that could result from a successful exploit. These assessments, commonly provided by vulnerability management tools, rely on factors like exploitability and impact to gauge the severity of each vulnerability. 

By prioritizing vulnerabilities based on their severity assessment, the focus is directed toward addressing those with the greatest potential impact on system security, ensuring that resources are allocated effectively to mitigate the most critical risks.

Common Vulnerability Scoring System (CVSS)

The severity of vulnerabilities is commonly measured using the Common Vulnerability Scoring System, or CVSS, a standardized method for rating vulnerabilities. CVSS assigns a score to each vulnerability on a 10-point scale, where higher scores signify greater severity. 

These scores are generated through formulas that take into account the likelihood and impact of an exploit, offering a consistent approach to evaluating vulnerability severity across different systems and environments.

Exploitability Factors

Vulnerabilities undergo evaluation based on exploitability factors, which encompass elements such as attack vectors, attack complexity, privileges required, and user interaction. 

These factors play a huge role in assessing how readily a vulnerability can be exploited by potential attackers and the level of expertise or access necessary to carry out an exploit effectively.

Impact Assessment

The impact of vulnerabilities is evaluated across three key dimensions: confidentiality, integrity, and availability. Confidentiality pertains to preventing unauthorized access to sensitive information, while integrity concerns unauthorized modifications or alterations to data. 

Additionally, availability addresses potential disruptions to system operation. 

Assessing the impact of vulnerabilities in these areas can allow organizations to prioritize remediation efforts. This is done by concentrating on those vulnerabilities that pose the greatest risk to data security and system functionality, ensuring that resources are allocated effectively to mitigate the most significant threats.

Data Sensitivity

When ranking and categorizing vulnerabilities, the sensitivity of data processed by affected systems is taken into account. This includes highly sensitive information like personal health data or financial records, which warrants heightened attention and priority for remediation efforts. 

Assigning data sensitivity ratings enables vulnerabilities threatening the confidentiality and privacy of sensitive data to be prioritized. This ensures that resources are directed toward addressing the most critical risks to data security and privacy.

Evaluation of Existing Controls

Vulnerabilities are assessed within the framework of existing security controls and safeguards. Systems equipped with robust security measures are assigned lower risk rankings, given their enhanced resilience against exploitation. This evaluation of existing controls aids in prioritizing vulnerabilities by identifying those that pose heightened risks due to insufficient protection measures. 

Vulnerability Management vs. Vulnerability Assessment

Vulnerability assessment and vulnerability management are two different terms that are often confused by people. Keep reading to understand how these methodologies differ from each other. 

Vulnerability Assessment: Identifying Potential Weaknesses

A vulnerability assessment is a one-time project conducted by external information security consultants with a specific start and end date. It involves the comprehensive review of an organization’s IT environment to identify and classify vulnerabilities in computer systems, applications, and network infrastructures.

Through detailed analysis, vulnerabilities are categorized, and a comprehensive report is generated, listing identified vulnerabilities along with actionable recommendations for remediation. The primary focus of vulnerability assessment is to uncover potential weaknesses within the organization’s IT environment, aiding in prioritizing remediation efforts based on the severity of vulnerabilities.

Vulnerability Management: Continuous Risk Mitigation

Vulnerability management is an ongoing, comprehensive program that continuously manages an organization’s vulnerabilities holistically and continuously. It aims to establish controls and processes to identify, evaluate, treat, and report on security vulnerabilities in systems and software, ensuring proactive risk mitigation.

Vulnerability management operates as a continuous cycle, encompassing various stages such as assessment, prioritization, action, reassessment, and improvement. Vulnerability management integrates findings from vulnerability assessments into a broader framework, enabling organizations to make informed decisions on remediation, mitigation, or acceptance of risks.

Differences Between Vulnerability Assessment and Vulnerability Management

Vulnerability assessment serves as an initial step in identifying vulnerabilities, typically conducted within a specific timeframe. In contrast, vulnerability management involves ongoing and continuous activities aimed at effectively managing these vulnerabilities over time. 

While vulnerability assessment focuses solely on identifying vulnerabilities, vulnerability management extends beyond identification to include decision-making on how to address these vulnerabilities, whether through remediation, mitigation, or acceptance of risks. 

The 5-step Vulnerability Management Process

The Vulnerability Management Process involves a systematic approach to identifying, assessing, prioritizing, and addressing security vulnerabilities within an organization’s IT infrastructure. It typically consists of several interconnected steps:

5 step Vulnerability Management Process

Step 1: Asset Discovery and Vulnerability Assessment

This initial step involves identifying all assets within the organization’s network and conducting vulnerability scans to pinpoint security weaknesses. Vulnerability scanners are crucial in detecting vulnerabilities across various systems and applications.

Step 2:  Vulnerability Prioritization

Once vulnerabilities are identified, they are prioritized based on factors such as severity, potential impact on the organization, and likelihood of exploitation. Prioritization helps security teams focus on addressing the most critical vulnerabilities first, maximizing the effectiveness of remediation efforts.

Step 3: Vulnerability Resolution

In this step, security teams work to remediate or mitigate identified vulnerabilities. Remediation involves fully addressing vulnerabilities to prevent exploitation, such as applying software patches or fixing misconfigurations. Mitigation strategies may be implemented to reduce the risk posed by vulnerabilities temporarily until permanent fixes can be applied.

Step 4: Reassessment and Monitoring

After vulnerabilities have been addressed, the network is reassessed to verify the effectiveness of remediation efforts and ensure that new vulnerabilities have not emerged. Continuous monitoring of the network and the evolving threat landscape is essential to promptly detect and respond to emerging security risks.

Step 5: Reporting and Improvement

Vulnerability management platform provides reporting mechanisms to track key metrics and performance indicators, such as the mean time to detect and the mean time to respond to vulnerabilities. These reports enable stakeholders to assess the effectiveness of the vulnerability management program and identify areas for improvement.
