• CALDERA is an automated adversary emulation system that performs post-compromise adversarial behavior within Windows Enterprise networks. It generates plans during operation using a [planning system](#planning-system) and a pre-configured adversary model based on the [Adversarial Tactics, Techniques & Common Knowledge]( (ATT&CK™) project. These features allow caldera to dynamically operate over a set of systems using variable behavior, which better represents how human adversaries perform operations than systems that follow prescribed sequences of actions.
