New Cyber Command Structure Established by the Department of Defense
As we become increasingly immersed in the digital era, the Department of Defense is forming a new command structure aimed at enhancing cybersecurity efforts.
The Defense Cyber Defense Command (DCDC) is among the latest agencies formed within the Army, tasked with a single, crucial goal: protecting the United States from various digital threats that could jeopardize national security.
“My current role involves developing the framework and establishing command and control protocols. Understanding the technology, the people, and processes is important, but equally critical is knowing who’s in charge and how the authority is shared among entities like CISA, the FBI, the Coast Guard, and our own Department of the Army,” explained Colonel Adolph Rodriguez, who heads the DCDC’s Defense Critical Infrastructure division. He spoke at the recent TechNet Cyber conference.
DCDC, which used to be known as the Joint Force Headquarters-Department of Defense Information Network, was restructured to fit within a new semi-integrated setup under U.S. Cyber Command (CYBERCOM) in May 2025. For more details, you can check their history page.
Acknowledging the fast-evolving nature of cybersecurity, Stephen Bucci, a Heritage Foundation scholar and ex-Pentagon official, emphasized the urgent need to address these issues. He remarked, “We cannot afford to be complacent. We should always be looking for ways to improve our readiness.”
“The question is, how do we continue our operations in the face of an attack?” Rodriguez questioned, as reported.
While Cybercom and the Department of Defense have yet to issue statements on this matter, the White House has directed inquiries to the Department of Defense.
Challenges of State-Sponsored Cyber Attacks
The integration of DCDC as a subcommand under CYBERCOM was first established in the National Defense Authorization Act of 2025.
This new command has become increasingly vital for U.S. national defense, especially after reports indicated that Chinese hackers have been taking aim at U.S. infrastructure.
The CISA reported that state-sponsored threats from China are trying to position themselves for potential cyberattacks on critical infrastructure amid rising tensions between nations.
Rodriguez also raised an interesting point: “Why not utilize the capabilities of NorthCom and Cyber Command to create a permanent cyber campaign plan that builds on existing infrastructure, allowing us to enhance preparedness without necessitating structural changes?”
Not everyone agrees with the new command structure, however. Piero Tozzi, from the America First Policy Institute, argued this landscape is treated as a battleground by entities like the People’s Liberation Army. He believes that existing limitations in threat detection and dependency on technologies sourced from China have created vulnerabilities that we are only now beginning to address.
Rodriguez assured that essential services like power, water, and transportation are also under protection from cyber threats.
One notable group, Bolt Typhoon, is linked to Chinese hacking efforts that focus on these vital systems. A report from the NSA highlighted that “China has already infiltrated many of these infrastructures.”
“An attack of this nature could not only disrupt the global economy but could inflict severe, lasting damage on China’s economic connections as well,” Bucci warned.
The NSA also noted that some cyber adversaries have been quietly embedded in these systems for years, biding their time for a chance to strike.
“We must keep up our defenses because our adversaries—especially China—are constantly looking for ways to breach our systems. It’s a continuous battle to stay ahead,” Bucci cautioned.
