### IPMC/Shepherd notes:



--------------------
## Caldera

Caldera provides a modular platform for modeling, scripting, and executing
adversary behavior. It allows users to construct emulation plans, provides
agents for             communicating with the command and control server,
and enables users to evaluate             security detections in a
structured, scalable, and repeatable way. With the use of             plug-
ins and community-contributed features, Caldera supports a range of use
cases             including adversary emulation, purple teaming, detection
engineering, and continuous             security validation. Using Caldera,
defenders can emulate known threat actor behavior             and perform
other red team activity to evaluate their organization’s defensive
capabilities, test analytics, and find detection gaps. As a modular tool
based on the             MITRE ATT&CK framework, Caldera is designed to be
extensible, intelligence-driven,             and automation-friendly.

Caldera has been incubating since 2025-12-19.
