The Enhanced Mitigation Experience Toolkit (EMET) is a Free Microsoft utility that help you prevent hackers from gaining access to your system. Its Security mitigation technologies make it impossible or more difficult for an attacker to exploit vulnerabilities in a given piece of software. With EMET you can adjust settings with a consistent interface regardless of the underlying platform. EMET can help manage the risk while this is occurring by making it harder to hackers to exploit vulnerabilities in the legacy software.
EMET Main benefits :
1- Highly configurable and ease of use.
2- No source code needed and helps harden legacy applications.
3- There is no need to enable an entire product or suite of applications.
4- No need to locate up and decipher registry keys or run platform dependent utilities.
