Adding software composition analysis inspections to the pipelines in Azure DevOps

Integrating Software Composition Analysis (SCA) checks into your CI/CD pipelines is crucial for automating the identification of security vulnerabilities, license compliance issues, and outdated dependencies in your software projects. By incorporating SCA into your pipelines, you can detect and fix issues as part of the build process, ensuring that vulnerabilities are identified early, before deployment to production.

Here’s a step-by-step guide to integrate SCA checks into CI/CD pipelines using popular tools and services.

1. Prerequisites for SCA Integration

Before you integrate SCA into your pipeline, ensure the following:

  1. You have an existing CI/CD pipeline (e.g., using Jenkins, GitHub Actions, GitLab CI, CircleCI, or Travis CI).

  2. Your project uses package management (e.g., npm for JavaScript, pip for Python, Maven for Java, etc.).

  3. You have selected an SCA tool to use for scanning (e.g., Snyk, WhiteSource, Dependabot, OWASP Dependency-Check, Sonatype Nexus, etc.).

2. Choosing an SCA Tool

Several SCA tools integrate directly with CI/CD systems and offer vulnerability scanning, license compliance checks, and dependency management.

Popular SCA tools include:

  1. Snyk:

Provides security vulnerability scanning for open-source dependencies and offers fixes.

  1. OWASP Dependency-Check:

Identifies vulnerabilities in project dependencies and produces reports.

  1. WhiteSource:

Tracks open-source vulnerabilities and license compliance.

  1. Sonatype Nexus Lifecycle:

Helps in identifying security vulnerabilities, license issues, and policy violations in dependencies.

  1. GitHub Dependabot:

Can be used for managing dependencies and creating pull requests for updates and fixes.

You can choose one or more based on your project’s needs.

For this guide

I’ll cover Snyk and GitHub Actions as examples, but the concepts apply to any SCA tool.

3. Integrating SCA Checks into CI/CD Pipelines

Option 1: Using Snyk for Security and License Scanning

Step 1: Set Up Snyk Account

  1. Go to and create a free account if you don't have one.

  2. Link your GitHub, GitLab, or Bitbucket account to Snyk to allow it to access your repositories.

  3. Install the Snyk CLI tool on your local machine or CI/CD environment.

Step 2: Add Snyk to Your CI/CD Pipeline

  1. Now, integrate Snyk into your CI/CD pipeline.

  2. Below is an example of how to integrate it using GitHub Actions:

  3. Create or update the .github/workflows/snyk.yml file to define the pipeline.

Step 3: Review Results and Fix Issues

  1. Snyk test runs the security scan on your dependencies and provides a report about vulnerabilities.

If any vulnerabilities are found, Snyk will return a non-zero exit code, causing the pipeline to fail. This ensures that critical vulnerabilities are caught before deployment.

  1. Snyk monitor sends the current state of the project to the Snyk dashboard, allowing you to track vulnerabilities over time and get notifications for new issues.

Optional: Automatically Fix Issues (PR Creation)

You can configure the pipeline to automatically open pull requests to fix vulnerabilities.

Add the following step to the snyk.yml file:

This step will automatically create pull requests for vulnerable dependencies with fixed versions.

Option 2: Using OWASP Dependency-Check in Jenkins

Step 1: Install OWASP Dependency-Check Plugin (Jenkins)

  1. Go to your Jenkins dashboard.

  2. Install the OWASP Dependency-Check Plugin.

  3. Navigate to Manage Jenkins > Manage Plugins.

  4. Search for Dependency-Check Plugin and install it.

Step 2: Add Dependency-Check to Jenkins Pipeline

If you're using a Jenkins pipeline with a Jenkinsfile, you can add OWASP Dependency-Check to the pipeline to automatically scan your dependencies.

Example Jenkinsfile with Dependency-Check:

Step 3: View and Review Reports

Dependency-Check generates a detailed HTML report showing all vulnerabilities, their severity, and remediation steps.

You can view the report in Jenkins or download it to examine which vulnerabilities were identified.

Optional: Fail the Build on Vulnerability

To ensure that critical vulnerabilities fail the build, you can configure the pipeline to check for vulnerabilities' severity (e.g., HIGH or CRITICAL) and fail the build if necessary.

Example to fail the build if high-risk vulnerabilities are found:

4. Integrating Other SCA Tools

Sonatype Nexus Lifecycle (for advanced policy enforcement)

Sonatype Nexus provides an extensive set of capabilities for managing and securing open-source components. Integrating Nexus with your CI/CD pipeline allows you to enforce security and license policies before dependencies are added to your codebase.

Example Nexus Lifecycle CLI integration:

5. Best Practices for Integrating SCA

  1. Automate Dependency Scanning:

Always run SCA checks as part of the CI/CD pipeline to ensure continuous security monitoring.

  1. Fail Builds on Critical Vulnerabilities:

If vulnerabilities exceed a certain threshold (e.g., high severity), fail the build to enforce resolution before deployment.

  1. Monitor for New Vulnerabilities:

Set up tools like Snyk or OWASP Dependency-Check to continuously monitor for new vulnerabilities in your dependencies.

  1. Set Security Update Policies:

Create policies to regularly update dependencies, such as making dependency updates part of your sprint cycle or requiring regular updates via automated PRs.

  1. Track License Compliance:

Many SCA tools also track license compliance. Ensure you're using the right licenses for the OSS components in your project.

Summary

By integrating Software Composition Analysis (SCA) into your CI/CD pipelines, you can proactively identify vulnerabilities, manage dependencies, and ensure compliance. Tools like Snyk, OWASP Dependency-Check, and Sonatype Nexus help automate this process, enabling your team to stay secure without sacrificing speed.

By incorporating these checks, your team can mitigate the risks associated with third-party libraries and open-source components, ensuring the security, quality, and compliance of your code.
