DoD Zero Trust Strategy proves security benchmark years ahead of schedule with Microsoft collaboration

In 2022, the United States Department of Defense (DoD) released its formal Zero Trust (ZT) Strategy with the goal of achieving enterprise-wide Target Level ZT implementation by September 30, 2027. A pioneer among these departments is the United States Navy, which recently launched Flank Speed—a large-scale zero trust deployment that aims to protect more than 560,000 identities and devices while improving the overall user experience.  

As part of the department’s ongoing assessments of zero trust implementation, Flank Speed just underwent its second round of security assessments sponsored by the DoD Zero Trust Portfolio Management Office (PfMO)—with tremendous results. Just two years after the initial DoD guidance was issued, the United States Navy demonstrated that their integrated approach to security could achieve the department’s ZT goals, years ahead of schedule. The model developed by the Navy in collaboration with Microsoft can be replicated to help both civilian and defense agencies to similarly accelerate their own zero trust goals. 

During the exhaustive test, the comprehensive, integrated suite of Microsoft Security tools enabled Navy personnel to meet Target Level zero trust implementation, achieving 100% success in the 91 Target Level activities tested. Further testing of 61 Advanced Level zero trust activities determined the Navy had achieved success in nearly all (60 of 61) advanced Target Level activities.

The DoD expanded beyond traditional penetration testing to thoroughly evaluate all 152 zero trust activities. Prior to the month-long test, military personnel were trained on the effective operation of the comprehensive zero trust solution over the course of six months. This training allowed Navy personnel to detect and mitigate all attack vectors presented to them by the near-peer adversary assessment team.  

“Flank Speed’s unprecedented ability to achieve the very highest level of DoD ZT outcomes demonstrate to us that the department and the federal government that ZT cyber defenses work very effectively to protect and defend our data and systems against the very latest cyber-attacks from our adversaries.”

—Mr. Randy Resnick, Senior Executive Service, Chief ZT Officer for the DoD 

Components of success 

Flank Speed is a large-scale deployment born out of the need to securely facilitate remote workers at the onset of the COVID-19 pandemic and built on the Navy’s unclassified combined Azure and Microsoft 365 Impact Level 5(IL5) cloud. To achieve a secure operating environment, the Navy aligned its security approach around the DoD’s seven zero trust pillars—each of which represents its own protection area:  

As outlined in the diagram below, the Microsoft 365 E5 package combines best-in-class productivity solutions with comprehensive security technologies that can address all seven pillars of the DoD Zero Trust Strategy.  

This comprehensive and extensible zero trust platform supports a range of environments including hybrid cloud, multicloud, and multiplatform needs. It brings pre-integrated extended detection and response (XDR) services, coupled with cloud-based device management and cloud-based identity and access management to meet the security priorities necessary for all defense and civilian organizations. The specific technologies and implementation strategies that support each pillar are outlined in this blog post. Microsoft has also published a higher-level Security Adoption Framework (SAF) that provides guidance to organizations as they navigate the ever-changing security landscape. 

A partner agencies can trust 

Implementation of a zero trust solution from scratch can be a daunting task. A successful deployment requires the integration of properly configured technologies across numerous product categories. No single product can effectively achieve zero trust goals alone, but selecting a set of integrated capabilities whether first or third party can provide significant acceleration. In order to be effective in the long term, a zero trust implementation must also be flexible enough to adapt quickly to new adversary tactics. Following the White House Executive Order to improve the nation’s cybersecurity and protect federal government networks, Microsoft offered technical expertise that helped architect and deploy technologies aligned to the DoD ZT strategy, including continuous monitoring, big data analysis, and comply-to-connect components. 

The success of Flank Speed is a critical demonstration of this collaborative approach to implementation. That a complex and critical environment such as that belonging to the Navy fully met not only its Target Level zero trust activities, but nearly all of the Advanced Level criteria more than three years before the DoD’s 2027 deadline with a repeatable solution, is a testament that zero trust can be implemented effectively at scale across the government.  

Importantly, though Flank Speed itself is cloud-native, it has been deployed to extend its usability and security capabilities to both cloud-only and existing on-premises workloads and devices, both ashore and afloat. This gave the Navy a rapid path to increased security that was independent of any effort to modernize or sunset existing legacy assets. Along with the proven security achievements, this capacity to extend zero trust security to existing infrastructure could have wide-ranging benefits for organizations pursuing similar cybersecurity goals of a homogeneous security baseline across heterogeneous environments. 

A commitment to security and innovation 

Microsoft’s support in helping the United States Department of Defense and its branches achieve zero trust implementation also helps inform Microsoft’s own Secure Future Initiative, which aims to continuously apply the company’s cumulative security learnings in an effort to improve its own methods and practices, and to ensure that security is kept paramount in everything Microsoft creates and provides to its customers. Independent learnings gleaned as part of the Secure Future Initiative, in return, help Microsoft refine its approach in support of government organizations and a vast ecosystem of security partners. In this way Microsoft can work to ensure that zero trust environments supported by Microsoft 365 and Azure stay up to date, even as cyber threat actors change and mature their tactics and tools. This continuous collaboration advances the broader effort to secure and support the United States national security and the security posture of democratic organizations the world over.  

Microsoft commends the United States Navy for their milestone achievement. The United States Navy and the United States Department of Defense are proving that zero trust goes beyond compliance standards and has become a proven security methodology with real world results.
