Has your organization implemented a Secure Development Lifecycle (SDL) that integrates cybersecurity considerations at each phase for all systems, hardware, software, and services?

A Secure Development Lifecycle ensures cybersecurity is built into products from requirements through deployment and maintenance, rather than added as an afterthought. This includes security requirements gathering, threat modeling during design, secure coding practices, security testing during development, and security validation before release. It also covers post-deployment security monitoring and update processes.

Evidence could include SDL documentation showing security activities at each phase, security requirements templates, threat modeling artifacts, secure code review checklists, security testing results, and deployment security validation reports.
