In my site logs folder when i open error.php, i see lots of records per line as one is look like this -
2014-04-03 22:35:54 INFO 18.104.22.168 Joomla FAILURE: Username and password do not match or you do not have an account yet.
What does that mean actually as i never had to deal with logs in joomla. As far as i get, most probably someone tried to access my admin login and joomla logged it, is a hacking attempt? if it is, then the above IP banning is sufficient?
