We recently covered Microsoft's lesser-known Enhanced Mitigation Experience Toolkit (EMET) that adds protection against malware. Microsoft recently upgraded it to version 5.0 with even more protection against Internet nasties.
Microsoft explains one of the new features, called plugin protection:
The new Attack Surface Reduction (ASR) mitigation provides a mechanism to help block specific modules or plug-ins within an application, in certain conditions. For example, customers can now configure EMET to prevent their browser from loading Java plug-ins on external web sites, while still continuing to allow Java plug-ins on their internal company web sites.
Those plugins are a common security exploit hackers take advantage of, so this is a welcome addition to an already powerful tool.
