MITRE Caldera for OT is now publicly available as an extension to the open-source Caldera platform, allowing security teams to run automated adversary emulation exercises that are specifically focused on threats to operational technology (OT).
The first Caldera for OT extensions were developed in partnership between the Homeland Security Systems Engineering and Development Institute (HSSEDI), a federally funded research and development center that is managed and operated by MITRE for the Department of Homeland Security (DHS), and the Cybersecurity and Infrastructure Security Agency (CISA) to increase the resiliency of critical infrastructure.
Adversary emulation has long helped defenders of information systems exercise and improve their cyber defenses by using real adversary techniques. As an open-source, scalable adversary emulation platform with MITRE ATT&CK as its backbone, Caldera helps cyber defenders save time, money, and energy by automating adversary emulation operations, security assessments, and red-, blue-, and purple-teaming.
