Let's consider for a fact that we have a very pseudo secure environment. Pseudo referring to something that has been purified of everything that can be a source of vulnerability. So we have no compilers, no runtimes and of course no internet. Also we have some physical security, the whole thing is locked in a box with only the cables for monitor, keyboard etc. and a wire with a button on it to start the machine.
Boss asks, is there any way for someone to harm this system.
YES! SO MANY WAYS!
Just ctrl-A and delete, dude.
PS: My task is too keep the antivirus up to date....
