Was it really bad security protocols that led to them being compromised? I saw the story (didn't buy) where Talia breaks into the cave to steal them. It wasn't a walk in the park, it was carried out by a professional with exceptional skill and they only knew of the protocols because Ras suspected (to the point of functionally knowing) that Batman created them.
Now, his 'secret plans' thatSpoiler got ahold of during War Games, that's another matter...
