10 Tips to make your WordPress website more secure

When it comes to WordPress, security is a very important issue. Just like any system which is accessed by millions of people, WordPress faces many potential security issues, which can be easily prevented by taking certain precautions. In this article, we will suggest you 10 tips which can help you make WordPress more secure:

  1. First tip that you should definitely apply when it comes to improving the security of your WordPress account is to use clean codes and to remove all unused themes, plugins and other elements which are found in your content directory. The best way to ensure WordPress safety is to use single and/or double quotes.
  2. Another great way to make your WordPress database more secure is to change database prefix. Start by backing up your WordPress database (you can use the BackupBuddy plugin) and only then change the table prefix in wp-config.php. Simply, open your wp-config.php file found in the WordPress root directory and change the prefix (eg. from wp_ to wp_abc123).
  3. In order to ensure the security of your WordPress account, you should definitely use strong password and username. Password managers and passphrases are the best way to come up with secure password. Password managers are special applications that generate passwords and store them in a special secure database.
  4. Using anti-spam plugins and captcha in form can also improve WordPress safety. Anti spam plugins are used to automatically block spams in comments and they are easy to use, just install them and use them.
  5. Next, we suggest you using proper file permission. The best piece of advice we could give you is to never provide unwanted control. File and directories stored on computer filesystems have permissions who actually “decide” who can access, modify, write and read them.
  6. One important tip that you should definitely apply in order to ensure the safety of your WordPress account is to protect in against Brute Force Attacks and simply try to limit the number of login attempts. Brute Force Attack actually attacks the access to a certain site by trying out different passwords and usernames until it gets the right combination. Brute Force Attack can easily hack your account if you use simple passwords (eg. 12345) and usernames (eg. admin). So, in order to protect yourself, never use “admin” as username, use automatic password generator to generate strong password, use plugins to limit the number of attempts to log in your site, limit the access to wp-admin by IP, protect your server or use proxy/cloud servers.
  7. Next, never use the default keys which are usually provided by WordPress. Instead, you are recommended to change them from wp-config.php. WordPress security keys operate out-of-the-box, meaning that they should be customized in order to make them sufficiently strong. Starting from WordPress 3.0, WordPress uses eight security keys which are located in the wp-config.php file. The best protection step you can make is to replace WordPress default keys with long sequences containing randomly selected unique characters. This can be done manually or by using the secret key service in order to automatically generate keys.
  8. Relying on SSH and SSL encryption can also help you increase the security level of your WordPress site. What is SSH and SSL encryption? SSH and SSL rely on cryptographic building blocks to create a tunnel which can be used to transfer confidential data, while checking its integrity. Some WordPress users say that SSH is much easier to use compared to SSL and many of them tunnel http in SSH.
  9. In order to increase the safety of your WordPress page, you can use CloudFlare to fight malicious traffic. CloudFlare has developed special plugin which can be used with WordPress and it allows users to get the correct IP addresses of users commenting on individual sites and it also ensures better protection against spammers. CloudFlare functions like a reverse proxy, meaning that it allows you to see originating IPs.
  10. The last tip we can give you to make WordPress more secure is to disable trackback. WordPress sends and receives trackback and pings from and to other Internet sites and there can be hundreds of them daily. That is why it is important to disable them. Start by backing up your database, then log in to phpMyAdmin and find your WordPress database. Click on the SQL tab, and then execute this query:
