Doubter: "Just to reinterate, calculate the chances your information gets hacked on a network with “protections“ against the chances it gets compromised by me dropping a notebook with you info in it"
The chances that someone could read a dropped notebook is close to 100% (some handwriting is just illegible - lol). Most of the population can pick up an item and can also read - notebook hack complete.
The chance of stolen data with appropriate encryption applied being read is much lower. Encryption models are constantly updated to maintain a level of protection that would take more than a lifetime (and supercomputer-capacity that doesn't yet exist) to crack. That's just one of the layers of protection. Hackers have to try for direct access to the data before it's packaged up with encryption for transport (across the network or physically). It takes a screw-up by a human somewhere along the line to create a vulnerability. This is usually accomplished through social engineering, not the mechanics of some genius-hacker attacking a network (Hollywood is sooo inaccurate). I won't bother to calculate the odds for digital data, but I'm comfortable saying they're lower than the odds of someone being able to read a lost notebook.
