The ED will help build the organization’s red cyber capability—as part of both the Red and White cells—and capacity in support of the Certification and Accreditation (C&A) process. The ED will be responsible for creating new and innovative tools for Red Cyber Space Operators to use in cyber assessment operations of US Government and DoD critical networks.
