What to do for "Login attempt failed for admin." and "Access denied" to path admin? In Watchdog, I started seeing several entries like this:


  Login attempt failed for admin.


And


  access denied 2016/04/04 - 15:06  admin


These are generating a fair number of log entries.  The IP address is different for each request; they all geolocate to Russia.

Obviously, this is not me, and there doesn't appear to be any particular danger to my site, but is there a way to minimize such requests?
As an option you can rename path to login page, you can try Rename Admin Paths module to do it.
