BLUF -- Security by Design (SbD):
Embedding security considerations into every stage of the Software Development Lifecycle (SDLC, CCRM) will be crucial to proactively address vulnerabilities and build resilient systems.
Security by Design (SbD) is a proactive approach to securing your cloud infrastructure and applications. By integrating security considerations at every stage of the development lifecycle, you can significantly reduce vulnerabilities and build more resilient systems. Implementing SbD in Azure effectively requires a multifaceted approach. Here are the authoritative steps you should follow, along with relevant Azure tools and their effectiveness:
Implement Security by Design (SbD) using Azure -- (6).
Define Security Requirements and Governance:
Tool: Azure Security Center (ASC): Provides a centralized dashboard for managing security posture, identifying vulnerabilities, and enforcing compliance across your Azure subscriptions. ASC does threat protection policies and security recommendations to define your baseline security requirements.
Effectiveness: ASC offers a holistic view of your security posture, simplifies policy management, and facilitates continuous security monitoring.
Action(s):

3. Secure Development Practices:
Tool: DevOps Security Tools (DevSecOps): Azure offers various DevSecOps tools like Azure DevTest Labs, Azure Pipelines, and Azure Security Scanner. Integrate these tools into your development pipeline to perform (1) Automated security scans, (2) Build security into code, and (3) Do "Shift Security Left."
Shift Security Left (3): (1) A concept in the field of software development and security. It is an approach that emphasizes integrating security practices and measures earlier into the SDLC, typically in the Planning and Design Phase. (2) Developers incorporate security considerations and practices throughout the entire development process (SDLC, CCRM), including, threat modeling, secure coding practices, vulnerability assessments, and security testing. -- The Goal -- To identify and address security issues earlier in the development process, making it more cost-effective and efficient to fix any vulnerabilities or weaknesses discovered. (3) This approach is driven by the understanding that it is easier and less costly to identify and fix security issues in the early stages of development rather than waiting until later after the software has been deployed. -- Value -- By integrating security into the initial stages of the SDLC, organizations can reduce the risk of security breaches, ensure data privacy, and enhance the overall security posture of their software systems.
