Strengthening Software Security in an Era of Supply Chain Attacks #
The rise in software supply chain attacks has made it crucial to ensure the security of software artifacts. SLSA (Supply-chain Levels for Software Artifacts) offers a structured approach to securing the software development lifecycle, from code creation to distribution. One of the key components of this framework is SLSA Provenance, which ensures the traceability and integrity of software artifacts by verifying where, when, and how they were built. This helps organizations protect their software from tampering, creating a trusted framework for managing software supply chains.

What is SLSA?
The Supply-chain Levels for Software framework (SLSA) helps protect software supply chains from security risks. It ensures software is built and distributed securely, using progressive levels that guide companies from basic automation to fully traceable and tamper-proof processes.
Key Concepts of Supply-chain Levels for Software Artifacts #
SLSA Levels:
- Level 1: Uses automated builds to prevent errors and tampering.
- Level 2: Adds security checks like source code verification.
- Level 3: Requires SLSA Provenance and stronger controls for building software.
- Level 4: Ensures complete build reproducibility and artifact security with SLSA Provenance.
How Does the Supply-chain Levels for Software Compare to Other Security Frameworks? #
SLSA vs. NIST Cybersecurity Framework:
Focus: NIST offers broad guidance for overall cybersecurity but doesn’t focus much on securing software supply chains.
Advantage: The Supply-chain Levels for Software focuses more on protecting software integrity and offers clear steps for securing software artifacts with SLSA Provenance, complementing NIST’s broader approach.
SLSA-chain Levels vs. OWASP Software Assurance Maturity Model (SAMM):
Focus: OWASP SAMM helps create security strategies for software projects.Advantage: The Supply-chain Levels for Software dives deeper into supply chain security. It focuses on provenance and reproducibility, while SAMM covers general security. SLSA Provenance ensures the safety and authenticity of software artifacts.
Supply-chain Levels vs. CIS Controls:
Focus: CIS Controls give guidelines for securing IT systems but don’t focus on software development or artifacts.
Advantage: The Supply-chain Levels for Software provides clear steps for securing software builds, using Supply-chain Levels for Software Artifacts Framework to verify that each build is secure and tamper-free.
Why Choose the Supply-chain Levels for Software Over Others? #
There are many security frameworks, but the Supply-chain Levels for Software stands out by focusing on the software supply chain. It offers easy-to-follow steps to improve software integrity and provenance, making it a strong choice alongside broader security frameworks.
- Supply Chain Focus: The Supply-chain Levels for Software is designed specifically to secure software supply chains, providing clear guidance on artifact integrity and SLSA Provenance.
- Levels of Assurance: The tiered levels let organizations improve security step by step, offering a clear path for continuous improvement.
- Artifact Integrity: The framework emphasizes reproducibility and provenance, ensuring software security in ways other frameworks don’t.
- Comprehensive Coverage: By securing software from code to artifact, the Supply-chain Levels for Software provides full supply chain protection, ensuring tamper-proof builds with SLSA Provenance.
- Complementary: The Supply-chain Levels for Software works well with frameworks like NIST or CIS Controls, enhancing overall security by addressing software supply chain vulnerabilities.

Frequently Asked Questions #
SLSA (Supply-chain Levels for Software Artifacts) is a framework that enhances software supply chain security by preventing tampering and ensuring artifact integrity through SLSA Provenance. It is critical for CI/CD pipelines as it establishes a security foundation throughout the software build and distribution processes.
SLSA stands out as one of the best standards for securing CI/CD pipelines. It offers comprehensive guidelines to secure each step of the pipeline—from source code management to artifact delivery—by preventing tampering and unauthorized access. SLSA Provenance verifies and ensures artifact integrity throughout the process.
Google initially developed the SLSA framework, and the OpenSSF (Open Source Security Foundation) now governs it. This organization promotes best practices for securing software supply chains and continuously improves the framework to meet new security needs.
