Securing the Software Supply Chain: OpenSSF, SLSA, SBOM, and Sigstore
0. Introduction
As software supply chain attacks become more frequent, securing software development processes is now a top priority for organizations.
Open-source software is at the core of modern applications, but its security challenges, such as unverified dependencies, tampered build and lack of transparency, making it vulnerable to attacks.
To address these concerns, the industry has developed several security frameworks and tools, including OpenSSF, SLSA, SBOM, and Sigstore. These initiatives work together to improve software integrity, transparency, and verification. Let’s explore what each one does and how they contribute to securing the software supply chain.
1. OpenSSF: The Collaborative Effort for Open-Source Security
The Open Source Security Foundation (OpenSSF) is a Linux Foundation initiative dedicated to improving open-source software security. It brings together organizations, developers, and security experts to develop best practices, tools, and frameworks.
Key OpenSSF projects include:
- Scorecards: Automatically rates open-source projects based on security best practices.
