Wed - February 14, 2007 at 02:05 PM inSecurity through SegmentationHere's an interesting article about the security model for the $100 laptops.
Basically, they're relying on extreme segmentation--each application plays in
its own sandbox, so malicious software can't do anything to the system or
applications even if it gets installed.
It also looks like they're using secure
application signing as a ways to give applications access to resources outside
their sandbox--possibly a weakness (if they key is ever compromised), but better
than what anything else does
today.
I've thought about this idea in the past, and it's very sensible. Very few applications actually need to access data and resources from other applications, and allowing open communications creates a lot of opportunities for mischief. Posted at 02:05 PM | Permalink | | | |
