You were talking about Iran and Stuxnet earlier, which was a worm and therefore network related rather than simply part of the computer...Routers and switches are very much part of the private network and play an important part in keeping a system secure from external attack.

This is a double-edged sword since the code is open-source it is open to abuse but on the other hand it is also open for security trials and fixes as well. Instead of a small group battling against the world of abusers there is a whole world of fixers battling against them.....

Still, it is not safe. It is hard to know what nefarious code lurks inside. Is this what you mean?
Now we are jumping to embedded software and "security" against software failure, which is a completely different topic. The most recent one hitting the news is probably the Toyota troubles with their electronic throttle:

There is a pdf version for those interested ...just google the title
Thankfully, Toyota don't make aeroplanes.....
