Is OS sandboxing the next step to secure computing?

Invisible Things Lab has released an open-source desktop operating system that uses the sandboxing of applications and processes to boost security.

Qubes 1.0, released Tuesday by the Polish company, uses lightweight Xen virtual machines as isolated domains. The architecture enables IT staff and other users to set security policies for each domain.
Joanna Rutkowska, founder and chief executive of the company, described Qubes as "reasonably secure," saying to call it unbreakable would be an overstatement.

"I use the term reasonably secure, because when it comes to defensive security, it's difficult to use definite statements -- secure, unbreakable, etc. -- unless one can formally prove the whole design and implementation to be 100% secure," Rutkowska said in a blog post. Nevertheless, Qubes OS is safer than other desktop operating systems because it allows users to build walls around each part of their digital life, the CEO argues.

For example, a work domain could be where people get access to work email and reports, slides, papers and other sensitive documents that can't be shared with any other domain. Network access could be restricted only to the work.
