MITRE has officially launched the Embedded Systems Threat Matrix (ESTM), a new cybersecurity framework designed to help organizations better protect the embedded systems that underpin critical infrastructure and advanced defense technologies. Developed in close collaboration with the U.S. Air Force’s Cyber Resiliency Office for Weapon Systems (CROWS), ESTM delivers a structured and practical approach to understanding, modeling, and defending against cyber threats that specifically target embedded environments.
As digital transformation accelerates across industries, embedded systems increasingly serve as the operational backbone of transportation networks, energy grids, healthcare devices, industrial control systems, robotics platforms, and military technologies. However, these systems often operate with unique constraints and risk profiles that traditional IT security frameworks do not fully address. With this in mind, MITRE designed ESTM to close a long-standing gap by focusing exclusively on the tactics, techniques, and attack patterns most relevant to embedded technologies.
“Embedded systems are the foundation of our critical infrastructure and defense capabilities, but they face complex and growing cyber risks,” said Keoki Jackson, senior vice president, MITRE National Security. “ESTM fills a key gap by giving defenders clear, actionable information to identify and stop cyber threats against these essential systems.”

Importantly, ESTM reflects MITRE’s mission-first, public-interest approach as a not-for-profit organization. Rather than offering a theoretical model alone, the framework provides hands-on tools that researchers, technology vendors, engineers, and security teams can immediately apply. As a result, organizations can more easily identify embedded-system vulnerabilities, map potential adversary behavior, and integrate targeted defenses into their existing security programs.
Furthermore, ESTM draws inspiration from the widely adopted MITRE ATT&CK framework. Building on MITRE’s proof-of-concept work and long-standing research into cyber-physical and embedded security, ESTM organizes embedded-specific threats into clearly defined tactics and techniques. This structure allows security teams to seamlessly extend current detection and response strategies into environments that have historically lacked standardized threat models.
In addition, ESTM aligns closely with the MITRE EMB3D Threat Model, together offering a more complete resource for designing, assessing, and maintaining secure embedded systems. While EMB3D supports secure-by-design principles, ESTM adds an operational threat perspective, enabling organizations to connect architecture decisions with real-world attack scenarios. Consequently, security teams can better anticipate how emerging technologies, expanded connectivity, and evolving adversary capabilities may impact embedded deployments.

Another key strength of ESTM lies in its forward-looking design. Beyond cataloging today’s known attack techniques, the framework also addresses emerging weaknesses and evolving threat patterns. This proactive focus helps organizations prepare not only for current risks, but also for future challenges that may arise as embedded systems become more intelligent, autonomous, and interconnected.
Finally, MITRE is actively encouraging collaboration from the global cybersecurity community. By inviting researchers and practitioners to contribute insights, use cases, and technical findings, MITRE aims to continuously refine ESTM and ensure it remains relevant across sectors and threat landscapes.
Overall, the launch of the Embedded Systems Threat Matrix marks a significant milestone in embedded security. By delivering a dedicated, actionable framework, MITRE is empowering organizations to better defend the hidden technologies that quietly power critical services, national infrastructure, and defense operations worldwide.
