Microsoft Research Showcases New Browser Prototype, "Gazelle" 125

Posted by ScuttleMonkey from the foxes-gazelles-and-natural-selection dept.
Ars Technica reports that Microsoft has opened up about "Gazelle," a new browser prototype of theirs that is modeled after the underlying concepts of operating system design. "A research team led by Microsoft's Helen Wang recently published a report about an experimental browser prototype called 'Gazelle' that uses processes to isolate page content elements originating from different domains. It builds on the concept of multiprocess browsing but uses more fine-grained isolation to expand on the security advantages that are already delivered by existing multiprocess browsing models. But is it an operating system, Microsoft Research's analogue to Google's Chrome OS? Not quite."

    Microsoft focusing on developing a browser-based OS is directly opposed to their current business model, which involves forcing users to purchase an operating system. Microsoft's focus has always been on for-pay, offline applications. Taking a precautionary foray into Google's future business model seems to show that they are at the very least wary of Google's future plans.

    MS's idea is nice, but it's not going to help a lot of things very much. It'll help when plug-ins and helper apps go runaway, being in a separate process they won't be able to block the browser itself. But from a security standpoint the problem isn't that those embedded objects are in the same process, it's that they have access to the same page and the DOM elements in it and the data structures of the browser itself. And that won't be solved just by putting them in their own process, not without isolating them from the rest of the page and browser to a degree that'll break a lot of Microsoft's technologies.

The goal is NOT to make something you can take to the open market though. It's a proper research lab, and so of course its stuff is frequently lacking.

    It builds on the concept of multiprocess browsing but uses more fine-grained isolation to expand on the security advantages that are already delivered by existing multiprocess browsing models.

    That's a new definition of security of which I was previously unaware. Just about anyone who's spent five minutes trying to do multi-process, multi-thread, unsyncronized accesses, cloud, spin-locks, etc., will tell you that no, there are no inherent security advantages. It'll be less secure unless you make a dedicated effort from project start just to keep it on par with single-threaded. The only "advantage" it has is that when it fails it'll crash more slowly, with a wider variety of obscure error messages, hammering the operating system as it tanks with the extra overhead as it does so. Yes, it might be slightly harder to develop an exploit because it's not using a generic flaw, but some complicated and obscure flaw -- but that's not more secure; Only badly designed.

It would be nice to see Javascript running inside a VM - CLR or JVM, followed by other languages with the same access that Javascript has.
