WordPress is the most popular blogging and CMS system on the Internet which makes it a favorite target for hackers.
Keep your WordPress site up-to-date
It is really important to keep your core WordPress files and all of your plugins updated to their latest versions. Most of the new WordPress and plugin versions contain security patches.
Protect your WordPress Admin Area
It is important to restrict the access to your WordPress admin area only to people that actually need access to it. If your site does not support registration or front-end content creation, your visitors should not be able to access your /wp-admin/ folder or the wp-login.php file. The best you can do is to get our home IP address and add these lines to the .htaccess file in your WordPress admin folder replacing xx.xxx.xxx.xxx with your IP address.
Deny from all
Allow from xx.xxx.xxx.xxx
In case you want to allow access to multiple computers (like your office, home PC, laptop, etc.), simply add another Allow from xx.xxx.xxx.xxx statement on a new line.
If you want to be able to access your admin area from any IP address (for example, if you often rely on free Wi-Fi networks) restricting your admin area to a single IP address or to few IPs can be inconvenient. In such cases we recommend that you limit the number of incorrect login attempt to your site. This way you will protect your WordPress site from brute-force attacks and people trying to guess your password. For such purposes, you can use a nice little plugin called Limit login attempts.
Don’t use the “admin” username
Most of the attackers will assume that your admin username is “admin”. You can easily block a lot of brute-force and other attacks simply by naming your admin username differently.
Use strong passwords
Use strong password ,it will help you to protect site from hackers.
Use secured WordPress hosting
Your WordPress site is as secured as your hosting account. If someone can exploit a vulnerability in an old PHP version for example or other service on your hosting platform it won’t matter that you have the latest WordPress version. This is why it is important to be hosted with a company that has security as a priority.
Some of the features that you should look for are:
1.Support for the latest PHP and MySQL versions
3.Web Application Firewall
4.Intrusion detecting system
