Hi Olaf,
SSH brute force attacks are commonplace on any internet facing server with port 22 open. You have a number of countermeasure options:
1) install fail2ban which will block anyone who fails a login 3 times
libpam-abl could be a good option too, since it doesn't rely on parsing the log files.
