Produce Well-Secured Software (PW)

Produce Well-Secured Software (PW) in the Build and Deploy CI/CD Steps

Produce Well-Secured Software (PW)

Organizations should produce well-secured software with minimal security vulnerabilities in its releases.


PW.1

Design Software to Meet Security Requirements and Mitigate Security Risks: Identify and evaluate the security requirements for the software; determine what security risks the software is likely to face during operation and how the software’s design and architecture should mitigate those risks; and justify any cases where risk-based analysis indicates that security requirements should be relaxed or waived. Addressing security requirements and risks during software design (secure by design) is key for improving software security and also helps improve development efficiency.


To satisfy SSDF PW.1 in a build and deploy context using open-source tools, the focus shifts to:

  • Embedding security controls directly into the build process

  • Validating that build outputs (binaries, containers, packages) are hardened and free from known design-level weaknesses

  • Preserving traceability from design requirements to deployed artifacts

Tasks Tools

PW.1.1: Use forms of risk modeling, such as threat modeling, attack modeling, or attack surface mapping to help assess the security risk for the software.


PW.1.2: Track and maintain the software’s security requirements, risks, and design decisions.


PW.1.3: Where appropriate, build in support for using standardized security features and services (e.g., enabling software to integrate with existing log management, identity management, access control, and vulnerability management systems) instead of creating proprietary implementations of security features and services.
