Software Composition Analysis (SCA) is a cornerstone of DevSecOps, enabling teams to inventory, track, and secure the open source and third-party libraries in your applications. Not only is SCA a critical domain for the AZ-400 exam, but it also helps you build resilient, compliant, and high-quality software that meets modern security standards.
Incorporating SCA early in your workflow reduces risk by catching vulnerabilities before they reach production. Automate scans as part of your CI/CD pipelines for continuous protection.

Package Management Strategies

Maintaining control over the components in your software supply chain starts with a solid package management approach:
  • Single Source of Truth
    Host all approved binaries in a central repository to ensure consistency across teams.
  • Local Approval Repository
    Curate an internal feed containing only vetted packages, giving you complete governance over dependencies.
  • Azure Artifacts for Distribution
    Use Azure Artifacts to store, share, and manage NuGet, npm, Maven, Gradle, Universal, and Python packages.
The image outlines package management strategies in software composition analysis, focusing on maintaining a singular source, establishing a local repository, and leveraging Azure Artifacts. It also lists types of packages like NuGet, npm, Maven, Gradle, Universal, and Python.
By combining a central repository with a curated internal feed and the flexible distribution model of Azure Artifacts, you can improve traceability, enforce policy, and speed up your release cycle.

Managing Open-Source Software Components

Open-source libraries drive innovation but can introduce vulnerabilities if not managed properly. Adopt these best practices:
  1. Keep Dependencies Updated
    Upgrade to the latest stable releases to incorporate security patches and improvements.
  2. Map Transitive Dependencies
    Analyze indirect dependencies to reveal hidden vulnerabilities.
  3. Verify Package Integrity
    Use signatures or checksums to confirm that binaries have not been tampered with.
The image is an infographic about managing open-source software components, highlighting steps like utilizing the latest versions, recognizing security risks, addressing security issues, and verifying binary files. It mentions that software composition analysis helps in identifying and mitigating security risks.
Delaying remediation of known vulnerabilities can expose your organization to breaches. Set up automated alerts and prioritize fixes based on risk severity.
SCA tools simplify this process by scanning your codebase, reporting issues, and offering actionable remediation steps. Integrate these scanners into your build and release pipelines to ensure continuous monitoring and protection.
