Asset Discovery: Everything You Should Know | 2024 Guide

Last Updated on 9 February 2024 by admin

External Asset Discovery is the process of identifying and mapping all the digital assets that exist outside an organization’s internal environment. Some examples of digital assets are web applications, cloud services, Internet of Things (IoT) devices, and network devices.

This is a crucial practice for security and IT leaders, as it helps to mitigate the risk of cyber-attacks that often originate from outside the organization. In today’s digital world, cyber-attacks continue to pose a significant threat to businesses of all sizes, and external asset discovery is an essential tool in the fight against these attacks.

External discovery, also known as attack surface discovery, is critical for security and IT leaders because it provides a complete and accurate picture of the organization’s attack surface, helping them to identify vulnerabilities and implement measures security controls to protect against cyber threats.

One of the primary reasons why discovering your assets is essential is that it provides visibility into the organization’s digital ecosystem. Modern businesses have an extensive online presence, including numerous web applications, cloud services, and other technologies that can be accessed from outside the organization.

Attackers often exploit these technologies to gain unauthorized access to an organization’s systems or steal sensitive data. By conducting an in-depth and continuous discovery process, security and IT leaders can gain visibility into their digital ecosystem and identify potential vulnerabilities that attackers can exploit.

In this article, we discuss what exactly is asset discovery and how security leaders and IT professionals can take control of their organization’s digital ecosystem.

Monitoring Your Evolving Attack Surface

The attack surface refers to the total sum of all security risk exposures (known as attack vectors) that a malicious attacker can use in order to gain privileged access to a digital environment. These points may be known or unknown assets, and lie within hardware, software, and networks. Because attack surfaces are constantly growing and evolving, combatting their associated risks can seem intimidating.

Many security and IT professionals opt for the easy and possibly most obvious solution to this universal problem – reducing their attack surface. However, although it’s a start, this will not totally protect your network. And of course, this is almost impossible for larger organizations and those experiencing growth. Therefore, scalable security is becoming not only a popular but necessary solution.

What is Digital Asset Discovery?

Asset discovery refers to the process of identifying, categorizing, and documenting all the assets within an organization’s digital ecosystem. These assets can include software applications, virtual machines, databases, IP addresses and cloud services. Asset discovery provides a comprehensive view of an organization’s assets, allowing for better asset management, improved security, and streamlined operations.

This form of live and continuous security monitoring offers round-the-clock vulnerability management – notifying you of changes to your attack surface as soon as they appear.

Things like changes to firewalls, spinning up new VPNs, and using additional cloud services unavoidably increase your online exposure. So, it’s critical to have complete visibility of your attack surface as it grows and evolves over time.

Why is Asset Discovery Important?

Asset discovery is vital for several reasons. Firstly, it helps organizations maintain an accurate inventory of their assets, enabling effective resource allocation and cost management. Additionally, asset discovery plays a crucial role in ensuring security and compliance. By identifying all assets, organizations can better assess vulnerabilities, apply necessary patches, and implement security measures to protect sensitive data and prevent unauthorized access.

Key benefits of asset discovery:

Asset discovery simplifies compliance efforts by providing a comprehensive view of assets and their compliance status. This helps organizations avoid penalties and legal consequences while fostering a culture of trust and credibility with customers.

Common Challenges in Asset Discovery

Effective management of an organization’s attack surface requires overcoming various challenges in asset discovery. Addressing these challenges is crucial for comprehensive and proactive attack surface management. Some of the common challenges include:

Scale and Complexity

Large organizations with extensive IT infrastructures may find it challenging to discover and manage all assets accurately.

Dynamic Environments

Assets can be constantly added, removed, or modified, making it difficult to maintain an up-to-date inventory.

Lack of Standardization

Different asset types, vendors, and data formats can complicate the discovery process, requiring compatibility and integration efforts.

Shadow IT

With the rise of employee-owned devices and cloud services, organizations may struggle to identify all assets used within their environment.

Lack of Automation

Limited time and resources alongside using manual processes hinder efficiency and scalability of asset discovery efforts. If you are still using spreadsheets then you need to consider adopting asset discovery software.

How Does Asset Discovery Work?

Asset discovery works by using in-depth automated OSINT techniques to search the internet to identify and map assets that comprise your organizations digital perimeter. Assets can be defined as domains, IPs and FQDNs. Managing asset discovery manually is a complex and time consuming task and can often lead to unknown assets not being identified which could lead to increased risk.

In order to maintain an accurate asset inventory asset discovery needs to be conducted regularly as an organizations digital perimeter is constantly evolving. It’s critical to have tools in place that can identify and alert you of new services but also changes to know assets that could pose a risk.

Scanning the Network

The asset discovery process typically starts with network scanning tools. These tools traverse the network, identifying and logging devices and software running on them. They can discover both physical assets, such as computers and servers, and virtual assets, such as virtual machines and containers.

Data Collection and Analysis

Once the scanning phase is complete, the collected data undergoes thorough analysis. This step involves organizing the information into a structured format, such as a centralized database or asset management system. It also includes identifying relationships between different assets to better understand dependencies and potential risks.

Continuous Monitoring

Asset discovery is not a one-time event but an ongoing process. Continuous monitoring ensures that the asset inventory remains up-to-date, accounting for changes, additions, and removals. Regularly updated asset data allows businesses to make informed decisions and adapt quickly to emerging challenges.

Why Should I Use Asset Discovery?

This form of passive automated inventory management offers a wealth of benefits as a more efficient way to take control of your security posture.

Below are some of the main advantages of continuously mapping assets, outlining its importance in today’s cyber-climate.
