SBOM Tool

Introduction

The SBOM tool is a highly scalable and enterprise ready tool to create SPDX 2.2 compatible SBOMs for any variety of artifacts. The tool uses the Component Detection libraries to detect components and the ClearlyDefined API to populate license information for these components.

Download and Installation

Executables for Windows, Linux, macOS

We distribute executables and SBOM files of the tool in GitHub Releases page. You can go and download binaries manually or use commands below to get the latest version of the tool for your platform.

Please check the CLI Reference document for additional help regarding the CLI tool.

Package managers

WinGet

winget install Microsoft.SbomTool

Homebrew

brew install sbom-tool

Manual download

Windows (PowerShell)

Invoke-WebRequest -Uri "https://github.com/microsoft/sbom-tool/releases/latest/download/sbom-tool-win-x64.exe" -OutFile "sbom-tool.exe"

Linux (curl)

curl -Lo sbom-tool https://github.com/microsoft/sbom-tool/releases/latest/download/sbom-tool-linux-x64
chmod +x sbom-tool

macOS (curl)

curl -Lo sbom-tool https://github.com/microsoft/sbom-tool/releases/latest/download/sbom-tool-osx-x64

Building SBOM tool as docker image

Clone this repo and build the docker image.

git clone https://github.com/microsoft/sbom-tool
cd sbom-tool
docker build . -t ms_sbom_tool

You can then use the tool normally, by mounting the directories to be scanned using docker bind mounts.

SBOM .NET Tool

The sbom-tool can also be installed as a .NET tool using the following command:

dotnet tool install --global Microsoft.Sbom.DotNetTool

SBOM API NuGet package

Please add and authenticate the Microsoft GitHub NuGet package registry to your nuget.config. Then install the Microsoft.Sbom.Api package to your project using these instructions

Please check the API Reference document for additional help regarding the SBOM tool C# Api.

Run the tool

SBOM Generation

Once you have installed the command line tool for your OS, run the tool using this command:

sbom-tool generate -b <drop path> -bc <build components path> -pn <package name> -pv <package version> -ps <package supplier> -nsb <namespace uri base>

The drop path is the folder where all the files to be shipped are located. All these files will be hashed and added to the files section of the SBOM. The build components path is usually your source folder, tool will scan this folder to search for project files like *.csproj or package.json to see what components were used to build the package. Tool uses component-detection to scan for components and dependencies, visit its Github page to get more information about supported components. The package name and version represent the package the SBOM is describing.

Each SBOM has a unique namespace that uniquely identifies the SBOM, we generate a unique identifier for the namespace field inside the SBOM, however we need a base URI that would be common for your entire organization. For example, a sample value for the -nsb parameter could be https://companyName.com/teamName, then the generator will create the namespace that would look like https://companyName.com/teamName/<packageName>/<packageVersion>/<new-guid>. Read more about the document namespace field here.

SBOM Validation

With an SBOM file in hand, use the tool to validate the output file with the command:

sbom-tool validate -b <drop path> -o <output path> -mi SPDX:2.2

This sample command provides the minimum mandatory arguments required to validate an SBOM: -b should be the path same path used to generate the SBOM file. In this scenario, the tool will default to searching for an SBOM at the <drop path>\_manifest\spdx_2.2\manifest.spdx.json path. -o is the output path, including file name, where the tool should write the results to. -mi is the ManifestInfo, which provides the user's desired name and version of the manifest format.

Currently only SPDX2.2 is supported.

SBOM Redact

Use the tool to redact any references to files from a given SBOM or set of SBOMs with either of the following commands:

sbom-tool redact -sd <directory containing SBOMs to redact> -o <output path>

sbom-tool redact -sp <path to the SBOM to redact> -o <output path>

This command will generate a mirrored set of SBOMs in the output directory, but with the file references removed. Note that the SBOM directory and output path arguments can not reference the same directory and the output path should point to an existing, empty directory.

Integrating SBOM tool to your CI/CD pipelines

You can follow these guides to integrate the SBOM tool into your CI/CD pipelines

• Setting up GitHub Actions to use the SBOM tool.
• Setting up Azure DevOps Pipelines to use the SBOM tool.

Telemetry

By default, telemetry will output to your output file path and will be a JSON blob. No data is submitted to Microsoft.
