Harness SSCA enables organizations to achieve SLSA Level 3 compliance, which is crucial for ensuring tamper-proof software builds and safeguarding against supply chain attacks, while aligning with Executive Order 14028 for improved cybersecurity. SLSA, originally developed by Google and now maintained by the Open Source Security Foundation, is a security framework designed to protect the integrity of software artifacts, organized into levels that enhance software supply chain security. The blog post highlights the importance of SLSA in mitigating supply chain attacks, building consumer trust, enhancing software transparency, and providing a proactive defense strategy. Harness's Software Supply Chain Assurance (SSCA) module facilitates meeting all SLSA levels, with detailed processes for achieving each level, such as generating and signing provenance and ensuring isolated build environments to prevent tampering. This comprehensive approach, combined with SBOM lifecycle management, results in a robust supply chain security solution that addresses emerging threats.
