Knowing the origin with Package Provenance
In an era where high-profile security incidents involving the software supply chain have become all too common, the need for robust tools and practices to secure the software we rely on has never been more evident. One crucial aspect of ensuring supply chain security is package provenance, which allows for the tracking of the origin and authenticity of software packages.
Recently, the Open Source Security Foundation (OpenSSF) announced the release of SLSA 1.0, a significant milestone that promises to enhance the overall security of the software supply chain. We previously covered the SLSA framework and its role in securing the software supply chain in our article about SLSA.
One important tool that aids in securing the software supply chain is package provenance, a requirement within the SLSA framework. By leveraging package provenance, developers can effectively trace the origin and authenticity of software packages they utilize.
npm, one of the most popular package managers for JavaScript, made an exciting announcement coinciding with the release of SLSA 1.0. They introduced support for package provenance in a public beta, enabling developers to track the provenance of the packages they rely on using npm.
The benefits with Package Provenance
There are several significant benefits to utilizing package provenance:
Firstly, it enables the identification of malicious or tampered packages. By comparing the expected provenance of a package with its actual provenance, developers can quickly detect any tampering or malicious modifications. This empowers them to avoid utilizing such packages and mitigate potential security risks.
Secondly, package provenance fosters increased trust in the software supply chain. When developers possess knowledge about the origin and authenticity of the packages they integrate into their software, they can confidently ensure the security and reliability of their applications.
Thirdly, package provenance aids in compliance with security regulations. Many compliance frameworks emphasize the importance of tracking and validating the provenance of software (NIST SP800-53, ISO27001 etc.)
In addition to package provenance, the introduction of the Supply Chain Levels for Software Artifacts (SLSA) framework marks another important step in securing the software supply chain. SLSA provides organizations with a framework to construct, secure, and verify software artifacts, offering best practices that enhance the overall security of their software supply chains.
Other popular public package repositories such as PyPi, RubyGems, and Maven Central, are also exploring solutions like sigstore for code-signing. These solutions are expected to be similar to npm’s implementation, highlighting the growing industry focus on securing software supply chains. We closely monitor these developments and their potential impact on the industry.
Supply chain security concerns
If you get into the details of supply chain security, you might uncover several reasons why users could be apprehensive or even scared about the current state of affairs.
Supply chain security concerns users due to:
-
Vulnerabilities: The interconnected components of the software supply chain can have severe consequences if compromised.
-
Malicious actors: Expanding attack surfaces and tampered packages increase the risk of breaches and unauthorized access to sensitive data.
-
Lack of control: Limited visibility and understanding of the origin and security of integrated components leave users feeling helpless.
-
Supply chain attacks: High-profile incidents like SolarWinds highlight the potential for widespread disruption and data breaches.
-
Regulatory compliance: Various industries require tracking and validating software provenance to meet security regulations (Executive Order 14028, NIS2 and other).
Industry initiatives, such as SLSA and package provenance adoption, aim to address these concerns and restore confidence in the software supply chain!
