Checking in... Is your aircraft secure?

[Shark]

yesterday on the way from INT-MCO an airwisconsin flight checked in, and i can't remember exactly how he checked in, but the controller came back and asked if his aircraft was secure. after confirming that his aircraft was secure the controller instructed him to check in differently. someone please enlighting me.
i want to say he checked in "airwisconsin trip 888 Fl???"

For security reasons, may I suggest that this is probably not a post that should be answered? To do so would publicize what is and what is not the current security procedure.
