Shift-Left in GitHub Advanced Security refers to which concept?

• A. Thinking about security when contributing to the code or designing features, so the end product is more secure by default.
• B. Shifting deployment timelines earlier in the process.
• C. Moving all security tasks to the operations team after release.
• D. Shifting code to left in the repository organization chart.

Answer: (A)

Shift-left means bringing security into the earliest stages of development so the end product is secure by default. In practice, this means developers consider security while designing features and writing code, perform threat modeling, and weave security checks into the development workflow so issues are caught before they reach production. GitHub Advanced Security supports this by encouraging or automating security checks early in CI/CD, such as code scanning and dependency review, so vulnerabilities are addressed as code is created.

This is why the best description is thinking about security when contributing to code or designing features—the focus is preventive, integrating security from the start rather than after release. The other options describe timing shifts or organizational changes that don’t capture the idea of embedding security earlier in the development process.
