Software supply chains are increasingly targeted by sophisticated cyberattacks, with vulnerabilities present in various components such as open-source software dependencies, code repositories, and DevOps toolchains. These attacks exploit weaknesses to steal data, plant malware, or take control of systems, exemplified by high-profile incidents like Log4j and Solarwinds, which exposed the complexity and interconnectedness of supply chains. As predicted by Gartner Research, by 2025, 45% of organizations globally will have experienced such attacks, highlighting the urgent need for comprehensive security measures. To mitigate risks, organizations should secure code repositories, CI/CD tools, and artifact registries, assess security postures against established frameworks, govern OSS dependencies, produce detailed Software Bills of Materials (SBOMs), and manage artifact promotions with SLSA attestations. These practices aim to enhance the trustworthiness and security of software supply chains, further supported by solutions like the Harness Software Supply Chain Assurance module.
