Secure ICS OT

@cR0w I know my environment. Partially because I'm the guy actually installing said equipment.
@Secure_ICS_OT Fair. Just today I found another cell router hooked up to a site that no one had documented anywhere. Hence the frustration / snark on my end. And of course the router's admin interface was Internet facing.
@cR0w I had a vendor that thought they were bringing in a cellular service. I quashed that real fucking quick. Ain't going to happen.
