In an existing ATO, is a DHA eMASS record required?

A DHA eMASS record is indeed required in the case of an existing Authority to Operate (ATO). The eMASS (Enterprise Mission Assurance Support Service) platform serves as a crucial tool for managing the cybersecurity risk management framework throughout the lifecycle of information systems within the Department of Defense (DoD).

Maintaining a record in eMASS allows organizations to track compliance, manage vulnerabilities, and provide the necessary documentation to support ongoing security assessments. It helps ensure that ATOs are not only valid but also reflect the current state of the system’s security posture. Additionally, having an updated eMASS record facilitates communication and transparency during audits and reviews, ensuring that stakeholders have access to the most current data regarding the system's security measures and compliance status.

In summary, the necessity of a DHA eMASS record in the context of an existing ATO underscores the importance of ongoing monitoring and management of cybersecurity risks to maintain operational integrity and compliance with regulations.
