Microsoft developers are working on a new browser that they say could be far more secure than Google’s Chrome, Mozilla’s Firefox or Microsoft’s own Internet Explorer. The prototype is known as Gazelle and it uses a “browser kernel” that helps enforce security rules in order to prevent.

Gazelle is different as no existing browsers, including new architectures, have a multi-principal operating system constructed in such a way that provides the browser-based OS exclusive control to manage the protection of all system resources.

Gazelle’s security model is centered around protecting principals from one another by separating their respective resources into hardware-isolated protection domains. Any sharing between two different principals must be explicit using cross-principal communication (or IPC) mediated by Browser Kernel.
