In the security services life cycle, which phase involves engaging the right source?

• A. Initiation Phase
• B. Assessment Phase
• C. Solution Phase
• D. Implementation Phase

Answer: (D)

Engaging the right source happens when you move from planning into action and start delivering the chosen security services. The implementation phase is where you execute the approved plan, contract and onboard the needed vendors or internal teams, configure and integrate systems, and deploy the solution. This is the stage that brings the plan to life by coordinating with the people and organizations that will actually provide and support the services, ensuring everything is put into operation with the right resources and agreements in place.

Earlier phases focus on defining what you need and how to approach it: initiation sets objectives and scope, assessment examines current capabilities and gaps, and the solution phase outlines the design and selections. The act of bringing in the right source to perform the work and delivering the solution is performed during implementation.
