The document is a guide detailing the Synopsys SSDF Readiness Assessment, which evaluates whether an organization's software development practices align with the Secure Software Development Framework (SSDF) established by the National Institutes of Standards and Technology (NIST). It outlines the implications of new legislation requiring software producers to adhere to stringent security practices, particularly for software procured by U.S. government entities. The assessment identifies areas where organizations may lack conformance to SSDF tasks and provides recommendations for improvement. Additionally, it explains the significance of self-attestation for software suppliers and how the assessment can assist in meeting compliance requirements. The guide emphasizes the importance of aligning with the Office of Management and Budget (OMB) and Cybersecurity and Infrastructure Security Agency (CISA) requirements, particularly for software produced after September 14, 2022. It also discusses the assessment's role in enhancing software security while maintaining compliance with procurement activities.
