Are these CSRF messages dangerous? My log has 100's of them.
I would look at the IP addresses that the traffic is originating from. If it isn't your folks then you might want to look at blocking some IPs... or perhaps only allowing certain ranges to get to your server.
ntozier This system is for use world wide and the offending address are many. Allowing only certain IP ranges is not possible.
Are these CSRF messages something I should worry about?
My guess would be that someone is trying to break in. Just because its for use world wide doesn't mean that you shouldn't have some security on it.
