I don't really want to know about this since I would like to keep it really private and give my visitor their privacy as much as possible (Not that my blog is popular though).
I just installed Ubuntu with nginx from Digital Ocean with the Ghost preinstalled, but previously I was with Wordpress. Right now (At this moment while I'm writing) I keep seeing this log

It is coming every second as you can see and they never stop on this and I'm thinking is that they are trying wether to hack my site while I was on Wordpress or something is going on from these requests. I would like to find out about these attacks and block their IP if this is something bad going on. How would I find out or should I install some kind of module/plugin in my box in order to prevent this kind of behaviour?
