It doesn't matter if the connection is secured if the data itself is not secured. Transport security is a red herring in a complex system.

If you are driving a car at 70mph around a mountain pass, even a really strong guard rail leaves the possibility that you could plummet ten thousand feet to your death. If, on the other hand, you were driving on the Bonneville salt flats at 45mph, there is much, much less danger.

Secure your data. Then paint the bike shed.
