yeah, i know. i didnt say hack proof. im looking for hack resistant.
best thing ive come up with over the years is #1 if you can get away with it, example being its not a POS terminal or something that has to send data, never connect an embedded system to the internet.
the second thing would be local attacks. for the example of an arcade cabinet, dont have any external Drives or USB ports where someone could just slink up and plug in their usb flash drive and flash your system, or pop their dvd in, or such, while you leave a good game to go to the bathroom, im sure you get the idea.
Ive got a whole bay of easy access disk drives and card slots and usb ports so i can easily update things, but they are all closed up behind a big happ door with security locks and a hasp on top of that.
Ive also got a guinea pig.
ive got a pc that i test everything on first to see if any ill effects are noticed from an update or a new skin or whatever.
That is that PC's sole purpouse. if it gets eaten alive during a test, i dont give a crap.
truth is that ive got the physical show up at your house hardware hacker locked down and also the internet hacker searching open tcp ports is not even an issue.
my basic question that i am seeking an answer for is that lets just say for instance that some malicious bug gets to things and slips under all of the levels of security already in place,
my goal is to physically limit by using Hardware locked media so that the amount of damage that it could possibly do is severely limited Internally.
at the least i want to be able to make a backup of the OS, And Mame 32 and all related configurations to Mame,
So at rock bottom all i have to do is reinstall the OS and Mame, and everything else on top of that i dont even have to think about because its still all there unchanged.
