Access log “POST /wp-login.php HTTP/1.0” 400

15 in two days is nothing. I’ve seen thousands per day. If your passwords are good, don’t worry about it but please make sure the passwords are good by nerd standards and not by common standards.

If it really worries you, there are plugins out there like Limit Login Attempts that can help and I believe that the site’s highest ranked user, toscho, was working on a similar plugin but I don’t know the status of that.
