Summary

From Wikipedia, the free encyclopedia

Common Platform Enumeration (CPE) is a structured naming scheme for information technology systems, software, and packages. Based upon the generic syntax for Uniform Resource Identifiers (URI), CPE includes a formal name format, a method for checking names against a system, and a description format for binding text and tests to a name.^[1]

The CPE Product Dictionary provides an agreed upon list of official CPE names. The dictionary is provided in XML format and is available to the general public. The CPE Dictionary is hosted and maintained at NIST, may be used by nongovernmental organizations on a voluntary basis, and is not subject to copyright in the United States.^[1]

CPE identifiers are commonly used to search for Common Vulnerabilities and Exposures (CVEs) that affect the identified product.

CPE 2.3 follows this format, maintained by NIST:^[2]

cpe:<cpe_version>:<part>:<vendor>:<product>:<version>:<update>:<edition>:<language>:<sw_edition>:<target_sw>:<target_hw>:<other>

The version of the CPE definition. The latest CPE definition version is 2.3.

May have 1 of 3 values:

1. a for Applications
2. h for Hardware
3. o for Operating Systems

It is sometimes referred to as type.

Values for this attribute SHOULD describe or identify the person or organization that manufactured or
created the product. Values for this attribute SHOULD be selected from an attribute-specific valid-values
list, which MAY be defined by other specifications that utilize this specification. Any character string
meeting the requirements for WFNs (cf. 5.3.2) MAY be specified as the value of the attribute.
^[1]

The name of the system/package/component. product and vendor are sometimes identical. It can not contain spaces, slashes, or most special characters. An underscore should be used in place of whitespace characters.

The version of the system/package/component.

This is used for update or service pack information. Sometimes referred to as «point releases» or minor versions. The technical difference between version and update will be different for certain vendors and products. Common examples include beta, update4, SP1, and ga (for General Availability), but it is most often left blank.

A further granularity describing the build of the system/package/component, beyond version.

A valid language tag as defined by IETF RFC 4646 entitled «Tags for Identifying Languages». Examples include: en-us for US English, and zh-tw for Taiwanese Mandarin.

Here, * is used as a wildcard character:

cpe:2.3:a:ntp:ntp:4.2.8:p3:*:*:*:*:*:*
cpe:2.3:o:microsoft:windows_7:-:sp2:*:*:*:*:*:*
cpe:2.3:a:microsoft:internet_explorer:8.0.6001:beta:*:*:*:*:*:*

Introduction

In the world of cybersecurity and asset management, the Common Platform Enumeration (CPE) is a crucial attribute that helps identify and classify systems, applications, and services. The CPE field is a vital component of the Machine object, providing a standardized way to describe the platform, operating system, and software components of a machine. However, populating the CPE field can be a challenging task, especially when dealing with diverse operating systems and software configurations. In this article, we will explore the concept of CPE, its importance, and provide a step-by-step guide on how to populate the CPE field using the data collected by the agent.

What is CPE?

CPE is a standardized vocabulary for describing computing platforms, operating systems, and software applications. It provides a unique identifier for each platform, operating system, and software component, making it easier to identify and classify systems. The CPE dictionary is maintained by the National Institute of Standards and Technology (NIST) and is available in various formats, including XML and CSV.

Why is CPE Important?

CPE is essential in various domains, including:

• Cybersecurity: CPE helps identify vulnerabilities and patch management for systems and applications.
• Asset Management: CPE provides a standardized way to describe and classify systems, making it easier to manage and track assets.
• Compliance: CPE helps organizations comply with regulatory requirements, such as HIPAA and PCI-DSS.

Populating the CPE Field

To populate the CPE field, we need to use the data collected by the agent. The agent collects various attributes, including the hostname, platform, distribution, and CPU information. We can use this data to create a basic mapping to populate the CPE field.

Windows Platforms

For Windows platforms, we can use the following mapping:

Linux Platforms

For Linux platforms, we can use the following mapping:

Basic Mapping

We can create a basic mapping using the data collected by the agent. For example:

Example Use Cases

Let’s consider an example use case where we have a Windows Server 2019 Standard Evaluation machine with the following attributes:

Using the basic mapping, we can create a CPE value as follows:

cpe:2.3:o:microsoft:windows
cpe:2.3:a:microsoft:windows_server_2019_standard_evaluation
cpe:2.3:a:microsoft:windows_server_2019_standard_evaluation:21h2

Conclusion

Populating the CPE field is a crucial task in cybersecurity and asset management. By using the data collected by the agent and creating a basic mapping, we can populate the CPE field with a standardized value. This value can be used to identify and classify systems, making it easier to manage and track assets. In this article, we have explored the concept of CPE, its importance, and provided a step-by-step guide on how to populate the CPE field using the data collected by the agent.

Future Work

In the future, we can improve the CPE field population by:

• Using machine learning algorithms: We can use machine learning algorithms to improve the accuracy of the CPE field population.
• Integrating with other systems: We can integrate the CPE field population with other systems, such as vulnerability scanners and patch management tools.
• Providing a user-friendly interface: We can provide a user-friendly interface for users to populate the CPE field, making it easier to manage and track assets.
