Which of the following is a prerequisite for initiating a DHA RMF Rapid ATO?

The prerequisite for initiating a DHA RMF Rapid Authority to Operate (ATO) is the completion of necessary training programs. This requirement ensures that personnel involved in the process are adequately prepared and knowledgeable about the Risk Management Framework (RMF) and compliance standards specific to the Department of Defense (DoD) and Defense Health Agency (DHA). Training equips staff with the essential skills to effectively manage risks and ensure the security posture of information systems.

While other options may seem relevant, they do not reflect the established prerequisites for initiating the Rapid ATO process. For instance, while having certified cybersecurity staff is beneficial, it is not an explicit requirement for starting the Rapid ATO. Similarly, approval from external regulatory bodies may be a vital component in other contexts but is not specifically listed as a prerequisite in this scenario. Finally, replacing all IT assets is not a feasible or necessary requirement for initiating a Rapid ATO, as operational assets may need to undergo assessment rather than complete replacement. Therefore, completion of necessary training programs stands out as the key prerequisite to ensure effective implementation of the Rapid ATO process.
