No reason at all. Have you ever seen children keep all the sand in a
sandbox? I bet not. No computer scientist has ever seen it happen
either. Despite all the proof-carrying code, sandboxing, "safe"
compilers, none of them work, or can work, for a very simple reason:
It's the operating system stupid.
The operating system is the only part of the system that can enforce any
kind of working security. However, no mainstream OS chooses to do this.
Nevermind that the MMU on the silicon does all the security for you. The
OS has to go out of it's way to create all the holes and security
problems that are posted weekly to security sites.
If the OS has a flawed security model, you're screwed, period.
There are a few operating systems out there that actually have a
security model, none you will have heard of (Cosm started out as an OS,
CPU/OS still looks remarkably like a kernel interface). The public is
perfectly happy with the state of affairs because they have been
convinced that is the best that can be done. If the truth ever gets out,
the lawsuits will flow like water, so hush...
