As a system developer, you have the defender's dilemma: You have to defend against all possible attack vectors, and the attacker just needs to exploit one. There are many, many rules to follow w.r.t security of your system -- too many for this small textbox :). Systems are heterogeneous, and so are the exploits. A great example of this would be getting into a smart TV through broadcast signals (Weeping Angel). A good place to start would be at the system level with a DREAD, DREAD-D, STRIDE or other model analysis. This is often a creative process, and experience counts.
