Abstract

A computer system includes an ensemble moving target defense architecture that protects the computer system against attack using one or more composable protection layers that change each churn cycle, thereby requiring an attacker to acquire information needed for an attack (e.g., code and pointers) and successfully deploy the attack, before the layers have changed state. Each layer may deploy a respective attack information asset protection providing multiple respective attack protections each churn cycle, wherein the respective attack information asset protections may differ.
