DHA POA&M Enterprise Mission Assurance Support Service (eMASS) Practice Test

The correct answer is that one DHA Rapid Authority to Operate (ATO) can be issued at one time. This is based on the structured nature of the DHA’s approach to ensuring cybersecurity and risk management for its systems. The limitation to a single Rapid ATO helps maintain thorough oversight and alignment with security standards, ensuring that each system undergoing this expedited process receives adequate attention and evaluation. This single-issue policy not only enables the rapid deployment of secure capabilities but also ensures that the quality of security measures and compliance with documentation is upheld, minimizing potential vulnerabilities that could arise from distributing attention across multiple authorizations simultaneously.

This focused approach is essential in an environment where ensuring the security of health-related data is paramount, particularly given the stringent regulations surrounding health information security.
