In this paper, we describe Elix0r, a system designed to plan proactively and respond automatically to security incidents such as fast moving intrusions and reported vulnerabilities. Elix0r attempts to contain such incidents while trying to minimize the impact to supported business processes. The containment actions are executed by a robust, flexible response infrastructure whose core is a rich and expressive scripting language designed explicitly for response. The system is designed to work in a wide variety of environments ranging from highly managed environments like DMZs to completely unmanaged networks.
