MITRE introduces Embedded Systems Threat Matrix

MITRE introduced the Embedded Systems Threat Matrix (ESTM) to address cyber threats targeting embedded systems that support the nation’s critical infrastructure and defense technologies.

The framework provides practical tools intended for researchers, vendors, and security professionals to identify vulnerabilities and improve embedded systems, and it was described as applicable across multiple sectors cited in the release, including transportation, energy, healthcare, industrial controls, and robotics.

ESTM organizes tactics and techniques specific to embedded systems and was developed from MITRE’s proof-of-concept and theoretical research; it aligned with the MITRE ATT&CK framework, covered emerging threats and weaknesses, and was described as working with the MITRE EMB3D Threat Model to form a combined resource for secure system design.

The work was produced in collaboration with the Adaptive Incident Response (AIR) Force’s Cyber Resiliency Office for Weapon Systems (CROWS), and the framework was presented as one that could be added to existing security programs.

“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.”

MITRE encouraged cybersecurity experts to contribute their knowledge and experience to help improve ESTM.
