The security properties of Windows/NT are currently unknown since it
has seen little real torture testing. I know that people have tried to
attack my firewall, and savagely. How many NT boxes have withstood
such treatment? The NT security mechanisms are also more complicated,
which in my opinion means there are more potential bugs. Lastly,
Sameer has full source code to Linux (as does anyone who wants it). NT
is a closed system, and there is no way to personally verify that code
does what you think it should. I think its best to depend only on
source available systems for security if possible.
