Which military branch primarily oversees the implementation of eMASS?

The United States Army primarily oversees the implementation of eMASS (Enterprise Mission Assurance Support Service) as it plays a key role in managing security compliance and risk management for information systems within the Department of Defense. eMASS is used by various military branches; however, the Army is specifically designated as the lead agency for the development and maintenance of eMASS. This responsibility involves ensuring that the eMASS platform effectively supports the risk management framework and aligns with overall military objectives, particularly in ensuring a robust security posture for Army information systems.

The selection of the Army as the lead should be recognized in the context of eMASS as a tool that facilitates the continuous monitoring and assessment of cybersecurity compliance, which is critical for the Army's operational and strategic missions. Other branches also utilize eMASS but do not have the overarching responsibility for its implementation.
