Brute force attacks are executed by software’s which are aimed to gain entry to your site. The point is it tries multiple combinations of usernames and passwords again and again until it gets success. So due to such strong attacks your server runs out of memory and suddenly stops responding. If you are the only one running your blog (private blog/website) then you can deny your site login to everybody else except yourself.
<Files wp-login.php>
order deny,allow
Deny from all
# Only allow this IP
allow from xx.x.xxx.xx
# Allow another IP
allow from xx.x.xxx.xx
</Files>
To limit access to wordpress login page by IP address copy the code and paste it in your site’s .htaccess file just above everything. Next replace xx.x.xxx.xx with your IP address and make sure that your IP address stays static or else you have to change it every time. The second IP address is optional which you can remove if you want. Hope your single authored wordpress blog is much safer than before.
