91st Cyber Brigade completes rollout of ShadowNet

By Virginia National Guard

FAIRFAX, Va. — The Virginia National Guard’s Bowling Green-based 91st Cyber Brigade completed the nationwide rollout of its ShadowNet enterprise solution July 19, 2019, with the integration of the 125th Cyber Protection Battalion into the solution’s virtual private network.

ShadowNet is a custom-built private cloud based out of the brigade’s data center in Fairfax, Virginia, that uses VPN connectivity to provide its aligned units with 24-hour, seven-days-a-week remote access to critical cyber training at both the collective and individual levels. The brigade successfully integrated its three other cyber protection battalions – the 123rd, 124th, and 126th Cyber Protection Battalions – into the ShadowNet platform last January.

“I’m extremely proud to announce that the Soldiers of the 91st Cyber Brigade have completed the construction and rollout of ShadowNet, a world-class enterprise solution designed to propel operational innovation in the field of cyber training,” said Col. Adam C. Volant, commander of the 91st Cyber Brigade. “ShadowNet will allow us to leverage the expertise of cyber professionals across our four cyber protection battalions to build Soldier-centric programs and collective training environments that deliver breakthroughs in exercise complexity and cost efficiency. Its robust capabilities and scalability will help to deliver the agility we need to keep pace with our partners in private industry while outpacing our adversaries.”

ShadowNet provides the interconnectivity, computing power and storage required to support Shadow Labs, the 91st Cyber Brigade’s innovative cyber training application, through which the brigade will offer cyber-related courses and exercises to improve proficiencies at all levels.

Individual Soldiers will be able to access an extensive catalog of cyber courses on their laptops to develop critical skillsets, while the brigade will use Shadow Labs to conduct collective cyber training exercises for its Cyber Protection Battalions, Cyber Security Companies, Cyber Warfare Companies and Cyber Protection Teams.

“It’s impossible to overstate the significance of such an innovative platform being conceived, designed and ultimately built at the Soldier level,” Volant said. “Soldiers of the 91st Cyber Brigade who led this effort, like 1st Lt. Austin Jones and Sgt. 1st Class Aaron Sweeney, were able to leverage the unique skills and experience they brought with them from their civilian occupations to shepherd the ShadowNet project from its concept stage to its physical construction. The achievement of the ShadowNet solution is not only a testament to the expertise of the 91st Cyber Brigade’s ‘Shadow Warriors,’ but emblematic of their nature as National Guard citizen-soldiers.”

The 91st Cyber Brigade plans to use Shadow Labs to host Exercise Cyber Yankee for the first time in August of 2019, and Exercise Cyber Shield for the first time in 2020. Cyber Yankee trains Soldiers to react to domestic cyber attacks in defense of critical area networks, while the larger Cyber Shield exercise requires participants to defend networks and mitigate the effects of cyber attacks against critical infrastructure. The brigade expects the action of hosting major cyber exercises like these will provide its Soldiers with valuable experience, assist the growth of Shadow Labs’ inventory of training scenarios and offer substantial cost savings for its aligned units. The Cyber Shield and Cyber Yankee exercises were previously executed by private-sector contractors.

A major contributing factor to the 91st Cyber Brigade’s successful construction of the ShadowNet solution was its partnership with the U.S. Army’s Program Executive Office Enterprise Information Systems. In addition to providing the funding that was crucial for the physical construction of ShadowNet, PEO EIS offered expert guidance on its design to ensure that the ShadowNet training environments would also respond to the requirements of the Total Force.
