EMET is a toolkit for deploying and configuring security mitigation technologies. The tool is designed to help prevent hackers from gaining access to your system. EMET allows users to both configure the system policy for mitigations as well as to configure mitigations on a per executable basis. The first option allows the user to set the defaults for system supported mitigaitons. The second option allows the user to enable an EMET supported mitigation on an arbitrary executable.
