Answer 1

Limit access to ftp. For this, upload to server file .ftpaccess, and paste following code:

<Limit ALL>
Deny from all
Allow from Your.IP.Address
</Limit>

Also, limit access to most important files (like wp-login.php), uploading in the same folder file .htaccess:

<Files "wp-login.php">
Order Deny,Allow
Deny from all
Allow from Your.IP.Address
</Files>
