With Stuxnet worm seemingly demonstrating that even relatively secure and relatively isolated (ie not networked) and embedded systems are open to attack. Have people upgraded security measures to completely immune themselves from attack?
We wish we could, but there is always something new. Sometimes that patches to close the old holes even open new ones! The software is just too big and too complex to find all the holes.With Stuxnet worm seemingly demonstrating that even relatively secure and relatively isolated (ie not networked) and embedded systems are open to attack.

The only to have a completely is by isolating it physically from all inputs and outputs. No outside connections, not external ports, manual input at a terminal only, and probably only hard copy output.So is it possible to ever have a secure system? Is every electronic system open to attack?
Or did Stuxnet work because something like this had not become public knowledge therefore seen as a real risk?
