- Deploy the Enhanced Mitigation Experience Toolkit (EMET). This will help prevent exploitation by providing mitigations to help protect against this issue and should not affect usability of websites.
- Set Internet and local intranet security zone settings to "High" to block ActiveX Controls and Active Scripting in these zones. This will help prevent exploitation but may affect usability; therefore, trusted sites should be added to the Internet Explorer Trusted Sites zone to minimize disruption.
- xConfigure Internet Explorer to prompt before running Active Scripting or to disable Active Scripting in the Internet and local intranet security zones. This will help prevent exploitation but can affect usability, so trusted sites should be added to the Internet Explorer Trusted Sites zone to minimize disruption.
"The security mitigation technologies that EMET uses carry an application compatibility risk with them. Some applications rely on exactly the behavior that the mitigations block. It is important to thoroughly test EMET on all target computers by using test scenarios before you deploy EMET in a production environment. If you encounter a problem with a specific mitigation, you can individually enable and disable the specific mitigations. For more information, refer to the user's guide that is installed with EMET."
