some plugins exist but, i just found this Better WP Security plugin.
this plugins offer you some facility such as :

1. file protection
2. edit file permission
3. hidden your login
4. enable/disable ip address
5. enable/disable limit login
6. change the prefix of your table
7. modify htaccess
8. move common directory
9. autobackup database
10. etc
