NIST will leverage existing guidance, practices, and recommendations that may be applicable to DevSecOps. They have been and are being developed by NIST and other US government (USG) agencies, standards development organizations (SDOs), industry, and academia. NIST will also develop mappings to existing informative references to ensure the relationships among frameworks, guidance, practices, and recommendations are clear.
NIST held a virtual workshop in January 2021 on improving the security of DevOps practices; you can access the workshop recording and materials here.
Potential work that can be leveraged includes:
NIST Frameworks
NIST Technology Projects
NIST Technology Guidelines
Government, Industry, and Academia Guidance and Practices
Security and Privacy: general security & privacy, vulnerability management
Technologies: software & firmware
