Every keystroke on every device of every employee with access to sensitive data? Not sure how that would be implemented, do you think all their phones and private devices have some government Spyware running hidden in the background? Could be, but who knows…
Sure, you are right. The article basically says: “don’t do it cause we will catch you for sure” & “only people with character flaw as would consider doing it anyways”.
My point was mostly about the mention of catching spies when the approach signal stations.
