Question 1

During a risk workshop for the AI-assisted customer service platform, the team identifies Integrated Product Team as the deciding issue. The enterprise security engineer is expected to address the control objective without granting broader privilege than the business need requires. What is the MOST appropriate course of action? The delivery organization releases changes through 7 application or service pipelines.

1. Rely on a manual checklist performed during emergencies instead of establishing a repeatable preventive or detective control.
2. Embed security requirements, threat analysis, testing, approval, and change control throughout the chosen SDLC methodology and into maintenance.
3. Measure software-security effectiveness through auditable changes, defect trends, risk analysis, and evidence that controls reduce exploitable risk.
4. Secure the development toolchain, repositories, dependencies, CI/CD pipeline, runtime, and testing stack using least privilege, provenance, and automated security checks.

Correct answer: B

Why: Security is most effective when it is integrated into delivery rather than added as a final gate. It directly addresses Integrated Product Team without granting broader privilege than the business need requires.

Option review:

A: Manual emergency workarounds are fragile and do not provide the consistent assurance required by the scenario. That action can be useful in a different security decision, but it does not most directly address Integrated Product Team in this scenario.

B: Security is most effective when it is integrated into delivery rather than added as a final gate. It directly addresses Integrated Product Team without granting broader privilege than the business need requires.

C: Security effectiveness should be demonstrated by risk and control outcomes rather than the number of tools deployed. That action can be useful in a different security decision, but it does not most directly address Integrated Product Team in this scenario.

D: Software supply-chain and pipeline compromise can bypass otherwise secure source code, so the ecosystem must be protected end to end. That action can be useful in a different security decision, but it does not most directly address Integrated Product Team in this scenario.

Correct answer: A

Why: Security is most effective when it is integrated into delivery rather than added as a final gate. It directly addresses Agile, Waterfall, DevOps, DevSecOps, and Scaled Agile methodologies without granting broader privilege than the business need requires.
