EMET is a free utility that helps prevent memory corruption vulnerabilities in software from being successfully exploited for code execution. It does so by opt-ing in software to the latest security mitigation techniques. The result is that a wide variety of software is made significantly more resistant to exploitation even against zero day vulnerabilities and vulnerabilities for which an available update has not yet been applied. We encourage you to test out the beta release by downloading and installing it, asking questions about the new features, and reporting any issues you find for us to address before the final release. We plan to officially release EMET 4.0 on May 14, 2013.
Here are the highlights of the EMET 4.0 feature set:
EMET 4.0 detects attacks leveraging suspicious SSL/TLS certificates
EMET 4.0 strengthens existing mitigations and blocks known bypasses
EMET 4.0 addresses known application compatibility issues with EMET 3.0
EMET 4.0 enables an Early Warning Program for enterprise customers and for Microsoft
EMET 4.0 allows customers to test mitigations with Audit Mode
