Exposure Management in Cybersecurity

Adam Roeckl - November 7, 2023

What is exposure management?

Within the context of cybersecurity, exposure management is an organization’s process of identifying, assessing, and addressing security risks associated with exposed digital assets. Exposed assets include any endpoints, applications, or other cloud resources that can be used to breach an organization’s systems. Together, these assets make up an organization’s digital attack surface. As organizations seek to gauge the severity of potential threats and potential consequences, exposure management becomes critical to their task of risk assessment, management, and mitigation.

In this article, we’ll cover the key aspects of exposure management. We’ll look at the processes involved, strategies for implementation, and recommended practices for enterprises seeking to harden their security posture.

Let’s begin with a closer look at key components and processes related to exposure management.

Key components of exposure management

Ultimately, exposure management is structured around well-defined and systematic processes. These processes work together to identify and assess the risks among all digital assets vulnerable to cyberattacks.

Step 1: Identification of exposed assets

Regardless of size, every organization has a broad set of assets that are used for various business operations. These assets include:

Identifying all these assets is a crucial first step in exposure management. Asset identification sets the stage for an organization to understand where vulnerabilities might be found and which assets are at the highest risk of having vulnerabilities exploited.

Step 2: Attack surface mapping

Once an organization completes a full inventory of its assets, the next step is to understand how each asset is vulnerable to exploitation. Examples of exposure include:

  • Publicly accessible services
  • Open ports
  • Inadvertently leaked information, such as metadata or debugging statements
  • Operating system and application vulnerabilities

Mapping an attack surface creates critical insights for organizations, allowing them to think like an attacker and helping them better understand how exposures can be exploited.

Step 3: Risk assessment

Next, an organization should use attack surface and attack path mapping to assess the risks associated with each asset. An asset’s level of risk depends on factors such as:

  • The sensitivity of data handled by the asset
  • The likelihood for an exposed asset to be exploited
  • The potential impact of an attack

Step 4: Exposure prioritization

After assessing the risks of each asset, an organization can begin prioritizing remediation of their exposures. This step provides clarity about which exposures must be addressed immediately and which can be addressed later.

Step 5: Exposure mitigation

After prioritizing exposure risks, an organization’s IT and security teams can begin taking steps to eliminate the risks associated with an exposed asset. This may involve actions such as patching vulnerabilities, closing unnecessary ports, modifying access control policies, or even taking assets offline.

Step 6: Continuous monitoring

An organization’s attack surface is constantly changing, with different assets changing in their level of exposure and new security vulnerabilities discovered for any given asset. Exposure management depends on continuous monitoring to detect new risks as they happen and ensure that previous mitigation actions are still effective.

Now that we’ve covered the key processes involved in exposure management, let’s turn our attention to implementation strategies and practical cybersecurity measures.

Best practices and recommendations

Your organization can adopt best practices to further harden its security posture in light of its digital exposure. Consider the following recommended guidance.


To streamline exposure management, look to automate processes across the exposure management life cycle: asset discovery, real-time monitoring and risk assessment, prioritization, and remediation. Your digital asset exposure (and the corresponding attack surface) is constantly changing. Your organization cannot wait on a scheduled, manual run of an asset discovery process by the IT or SecOps team. Automation ensures that your exposure profile is constantly updated.

In addition, coupling automation with AI/machine learning (ML) tools can help you cut through the noise and make decisions faster. Beyond automated attack surface mapping, some tools may even be able to predict future exposure risks.

Regular audits

In addition to continuous monitoring and real-time analytics, your organization should perform regular audits of its exposed assets. These audits can validate the effectiveness of your strategies and implementation. Audits may also identify novel risks or help with prioritizing risk mitigation.

Education and training

In many organizations, the human element is a strong contributing factor to security exploits. Whether it’s falling for phishing attacks, carelessness with credentials, or unnecessarily elevating permissions, humans contribute to the risks associated with your exposed assets. As a result, education plays a vital role.

Ensure that your staff understands the risks associated with digital exposure and is trained to minimize these exposures. For example:

  • Developers can be trained in secure coding practices, helping to reduce the inadvertent exposure of sensitive data or services
  • IT teams can be trained to better understand the dangers of unnecessarily elevated permissions and adopt the principle of least privilege

When your team is better educated and informed, it will be better equipped to promote cyber hygiene and identify suspicious activity.

Navigating the complexities of exposure management

In this article, we looked at the core concepts surrounding exposure management. Modern enterprises are expanding — not reducing — their footprint of exposed assets. Their attack surfaces are ever-growing. For this reason, organizations need to adopt systematic processes and robust tools for exposure management.
