Microsoft strengthens its EMET security tool: Okay, it's not invulnerable but it's free

Microsoft has enhanced its Enhanced Mitigation Experience Toolkit ( EMET ) , adding features designed to block most exploits.

The release of the tool's beta version, EMET 5.0, brings new revelations about attacks against previous versions. EMET 5.0 beta comes with a feature called Attack Surface Reduction, which makes it easier for enterprise security administrators to enforce policies for the use or exclusion of third-party Java, Flash Player, and browser plug-ins.

EMET is designed to help reduce the risk of attacks that exploit zero-day vulnerabilities. Even Microsoft doesn't claim it's invulnerable, and the basic idea is to make life difficult for would-be attackers.
