Microsoft Shows Off Experimental Designs for OS and Browser
(...) Most ordinary Web surfers don’t realize that when they log in to their bank’s Web site while chatting on Facebook and answering Yahoo mail, the applications are not protected from one another. So a bug in Facebook can infect the application that’s paying the bills. Because the Web applications also have direct access to the operating system, an application gone rogue can also rummage through a person’s files and send out data over the Internet.
Even if a software program running in the browser isn’t infected with malicious code, it can still cause problems by hogging system resources, Wang says. For example, a misbehaving Web advertisement can monopolize processing power, memory, and network bandwidth.
To fix these problems, Wang proposes rethinking both the operating system and the browser. The architecture of most operating systems, including Windows and Linux, harks back to the era when multiple users shared a single mainframe computer. The systems were constructed so that people couldn’t access one another’s data, and an application being used by Alice wouldn’t interfere with another being used by Bob.
Wang says that instead of protecting people, the operating system should protect applications from one another. She and her colleagues have developed ServiceOS, a new operating system that manages security policies and resource allocation and exists as a small layer of code between Web applications and traditional operating systems, like Windows. For example, ServiceOS could decide that Facebook can send data only back to Facebook or that Adobe’s Flash cannot access any files.

The Gazelle Web browser, which is also being developed by Wang and her colleagues, will implement the security policies set by ServiceOS, isolating different applications from one another. What’s special about Gazelle, Wang says, is that “it is the first browser that is built with an operating system mentality.”
