A security engineer is required to integrate security into a software project that is implemented by small groups test quickly, continuously, and independently develop, test, and deploy code to the cl

Service-oriented architecture (SOA) is an architectural design pattern for structuring software as interoperable services, not a software development process or methodology for team-based iterative delivery.

The Spiral Methodology is a risk-driven development model that uses repeated planning, risk analysis, engineering, and evaluation phases - it does not emphasize the continuous, rapid, and independent deployment cycles described in the scenario.

Structured Waterfall Programming Development follows a sequential, phase-gated approach (requirements → design → implementation → testing → deployment) that is incompatible with the continuous and independent deployment cadence described in the scenario.

DevOps Integrated Product Teams (IPTs) emphasize small, cross-functional groups that continuously integrate, test, and deploy code in iterative cycles - matching the scenario exactly. Integrating security into this workflow (DevSecOps) means embedding security controls, automated scanning, and compliance checks directly into the CI/CD pipeline, enabling rapid and secure cloud deployments without slowing development velocity.
