MITRE Caldera™ is a cybersecurity platform designed for automated adversary emulation and red team operations. Built on the MITRE ATT&CK™ framework, the platform provides a comprehensive solution for security testing and incident response activities. The platform consists of two primary components: Core System: Features an asynchronous command-and-control (C2) server with REST API capabilities and a web-based management interface. This foundational framework handles the primary operational functions and provides the base infrastructure for security operations. Plugins: Modular extension repositories that enhance the core framework's functionality. These plugins add capabilities such as additional agents, reporting tools, collections of tactics, techniques, and procedures (TTPs), and other operational enhancements. The platform enables security teams to conduct automated adversary emulation exercises that simulate real-world attack scenarios. It supports manual red team operations by providing tools and frameworks for offensive security testing. Additionally, the platform assists with incident response activities through its integrated approach to security operations. The modular architecture allows organizations to customize their security testing capabilities based on specific requirements. Integration with the MITRE ATT&CK framework ensures that emulation exercises align with documented adversary behaviors and techniques.
