You should treasure the fact that you work in an org. where people care enough to even try!
If you are smart, cynical and cunning, (strongly recommended for security professionals!),
you can channel this into a benefit for you, your group and the whole company.
If you "Deputize" the eager-beavers, then it gives you a lot more eyes and ears.
Yes, sadly, you will have the annoying "I Just Read ...." know-it-alls, but even if
the involvement is in reality, an illusion, you still get more back than you invest.
With, of course, the concept of responsibility, focus, and "handover" ...
"Thank you for bringing this to our attention, you are, indeed, so-cool,
and now we can take it further, leaving you to get on with the things the
company actually pays you for ..."
The best example I've ever seen of this, is the Starling speech to the
troopers in the Silence of the Lambs.
A small barrier to entry, to keep out the assholes, is also advised.
A monthly, unpaid, evening meeting for the "security" associates,
with some feedback, news, updates and a doughnut, keeps things
running well.
In the end, as Corporate Security, you can either act like an occupying army,
or a police force that operates with the support of your users.
Treat your users like shit, and they will notice, and they will not have your back.
Of course, this is no guarantee that if you treat them well, they won't
stab you in the back anyway, but ... as a security person, you already know
that you will get to see the worst that people have to offer, ... anyway.
The really cynical would point out that if you really were, an occupying army,
then you should be smart enough to build up your "cadre" of supporters,
without visible points-of-protest, and for "counter-intel" usage ...
