Summary
The Enhanced Mitigation Experience Toolkit (EMET) is a utility that helps prevent vulnerabilities in software from being successfully exploited. EMET achieves this goal by using security mitigation technologies. These technologies function as special protections and obstacles that an exploit author must defeat to exploit software vulnerabilities. These security mitigation technologies do not guarantee that vulnerabilities cannot be exploited. However, they work to make exploitation as difficult as possible to perform. For more information about EMET, click the following article number to view the article in the Microsoft Knowledge Base:
2458544 The Enhanced Mitigation Experience Toolkit When EMET mitigations are applied to certain software or certain kinds of software, compatibility issues may occur because the protected software behaves similarly to how an exploit would behave. This article describes the kind of software that usually presents compatibility issues with EMET’s mitigations and a list of products that exhibited compatibility issues with one or more of the mitigations that are offered by EMET.
More Information
Generic guidelines
EMET mitigations work at a very low level in the operating system, and some kinds of software that perform similar low-level operations might have compatibility issues when they are configured to be protected by using EMET. The following is a list of the kinds of software that should not be protected by using EMET:
-
Anti-malware and intrusion prevention or detection software
-
Debuggers
-
Software that handles digital rights management (DRM) technologies (that is, video games)
-
Software that use anti-debugging, obfuscation, or hooking technologies
Certain host-based intrusion prevention system (HIPS) applications may provide protections that resemble those of EMET. When these applications are installed on a system together with EMET, additional configuration may be required to enable the two products to coexist.
Additionally, EMET is intended to work together with desktop applications, and you should protect only those applications that receive or handle untrusted data. System and network services are also out-of-scope for EMET. Although it is technically possible to protect these services by using EMET, we do not advise you to do this.
Application compatibility list
The following is a list of specific products that have compatibility issues in regards to the mitigations that are offered by EMET. You must disable specific incompatible mitigations if you want to protect the product by using EMET. Be aware that this list takes into consideration the default settings for the latest version of the product. Compatibility issues may be introduced when you apply certain add-ins or additional components to the standard software.
