What are the subordinate tasks of the Initiate and Plan IA C&A phase of the DIACAP process? Each correct answer represents a complete solution. Choose all that apply. Response:

Developing the DIACAP strategy is a core planning activity within the "Initiate and Plan IA C&A" phase, setting the overall approach for the C&A effort.

Assigning IA controls, which involves identifying and mapping controls to the system, is a critical planning task within the "Initiate and Plan IA C&A" phase to ensure appropriate security measures are considered.

Assembling the DIACAP team is an essential initial step in the "Initiate and Plan IA C&A" phase, bringing together the necessary personnel and expertise to execute the certification and accreditation process.

Initiating the IA implementation plan is a planning task in the "Initiate and Plan IA C&A" phase, laying the groundwork for how the chosen information assurance controls will be put into practice.

Registering the system with the DoD Component IA Program is a fundamental prerequisite and an initial task in the "Initiate and Plan IA C&A" phase, formally bringing the system under the C&A purview.

Conducting validation activity, such as security testing and evaluation, is typically performed during the "Assess IA Controls" phase (Phase 3) of DIACAP, not the initial "Initiate and Plan" phase.
