• Pentagon adopts Zero Trust in 2023 for data security.
• Addresses military alignment challenges through regular communication.
• Industry invests; Booz Allen Hamilton’s $1.86B Thunderdome deal marks a key milestone.

Pentagon embarked on a comprehensive journey to bolster its data security through the adoption of a Zero Trust strategy in 2023. This pivotal shift in cybersecurity strategy aimed to counter wide-scale and persistent cyber threats, with specific concerns raised about malicious activities originating from known and unknown actors, notably China.

The Defense Department Chief Information Officer, John Sherman, set an ambitious tone early in the year, emphasizing the urgency of implementing a full baseline version of the Zero Trust strategy by fiscal 2027. The approach, fundamentally challenging the traditional network security paradigm, hinges on continual user verification and assumes networks are always under the threat of compromise.

As part of its strategy, the Pentagon released a roadmap outlining the steps required to attain both a “targeted” and “advanced” level of Zero Trust. The move aimed to fortify the Defense Department’s information enterprise, acknowledging the evolving landscape of cyber threats.

The implementation process, however, faced challenges, as highlighted by Randy Resnick, director of the Department of Defense’s Zero Trust Portfolio Management Office. Coordinating the diverse efforts of individual military services into a cohesive framework proved challenging. In response, the Pentagon initiated regular communication channels, including weekly “huddles” and quarterly meetings, to educate and align different services with the envisioned Zero Trust strategy.

While the effectiveness of a full Zero Trust implementation in preventing the Discord leaks remains uncertain, Sherman expressed confidence that it would have significantly increased the likelihood of averting such incidents. The Defense Department took a proactive approach by reviewing and assessing Zero Trust implementation plans submitted by military services and components in October.

Industry response to the Pentagon’s ambitions was notable, with companies like General Dynamics Information Technology aligning their investments with the Department of Defense’s priorities. General Dynamics Information Technology’s president, Amy Gilliland, revealed a 50 percent increase in investment in critical areas, including Zero Trust, 5G, multi-cloud management, software factories, automation for IT operations, artificial intelligence and machine learning, quantum computing, and defensive cyber operations.

A significant milestone in the Zero Trust initiative was reached with the Defense Information Systems Agency’s Thunderdome program. Booz Allen Hamilton secured a substantial production agreement worth up to $1.86 billion, marking a crucial step in transitioning Thunderdome from prototyping to full-scale production.

As 2023 draws to a close, the Pentagon’s commitment to achieving true Zero Trust security remains evident, though the complexity of the journey underscores the formidable task of safeguarding the nation’s sensitive information in an increasingly digital and interconnected world.
