Yes, information can be secured. Where it can be accessed can be limited, the amount of information that can be retrieved can be limited, it can be recorded who retrieves what information and when, and so forth. This idea that you can't be 100% sure about the people who have access is exactly why you take such measures.

Seriously though, intelligence is everything in this day and age. If you don't secure your information it is like walking alone down a dark alley in the middle of the night while carrying a gold brick. You are just begging someone to take it.
