Just plug in that awesome looking Star Wars novelty USB stick you found in the carpark. It will soon become very interesting and unpredictable... 😉
Right sort of humor is of course essential, and here's some random thoughts.
When I was in the engine room we used to have a 'buy doughnuts for the team' policy if someone could access an unlocked computer. Would probably get arrested these days.
Role plays, scenarios all come into it - particularly on walk through's of incidents - have teams members research a technology and report back. Aim to send people to conferences, with objectives in pairs. Most of what keeps people ticking in people, or at least talking to them.
Run new technology evaluations, compare pros and cons for them. Ask for the ream to think how they would defeat these controls.
Have a mentorship program people can join.
Give people a path with a degree in it at the right level, a long team goal makes the drudgery go quicker.
