New Control System - Wireless Problems

[galewind]

if a team uses no wireless security and leaves their passwords as default on their wireless devices, what's to stop someone else from going in and changing passwords and wireless configuration settings from underneath of them, causing unnecessary stress on these teams? What do we have to prevent teams that don't exhibit gracious professionalism from doing nasty things with readily-available and commonly-accepted devices over a universally-used transmission protocol?

Am I misunderstanding this? Am I over-paranoid? Is this something that has been thought-through and just not shared with us yet?
