OWASP Software Assurance Maturity Model

Implementation
Implementation is focused on the processes and activities related to how an organization builds and deploys software components and its related defects.
Activities within the Implementation function have the most impact on the daily life of developers. The joint goal is to ship reliably working software with minimum defects.

Secure Deployment
One of the final stages in delivering secure software is ensuring the security and integrity of developed applications are not compromised during deployment. The Secure Deployment (SD) practice focuses on this. To this end, the practice’s first stream focuses on removing manual error by automating the deployment process as much as possible, and making its success contingent upon the outcomes of integrated security verification checks. It also fosters Separation of Duties by making adequately trained, non-developers responsible for deployment.
The second stream goes beyond the mechanics of deployment, and focuses on protecting the privacy and integrity of sensitive data, such as passwords, tokens, and other secrets, required for applications to operate in production environments. In its simplest form, suitable production secrets are moved from repositories and configuration files into adequately managed digital vaults. In more advanced forms, secrets are dynamically generated at deployment time and routine processes detect and mitigate the presence of any unprotected secrets in the environment.
