5. Test the website: After the SSL certificate is installed and the website URL and resources have been updated, it’s important to test the website to ensure that everything is working as expected.

By following these steps, website owners can move their WordPress website to SSL/HTTPS, improving the security of the website and protecting sensitive information transmitted between the website and its users.

You should change defult admin user

Using the default “admin” username for a WordPress website can make it easier for attackers to guess the username and gain access to the website. Here are the steps to change the default “admin” username in WordPress:

1. Create a new user: In the WordPress Dashboard, navigate to Users > Add New and create a new user with administrator privileges.
2. Log in as the new user: Log out of the current user account and log back in as the new user.
3. Delete the old “admin” user: Navigate to Users > All Users and delete the old “admin” user.
4. Assign the old “admin” user’s content to the new user: When prompted during the deletion process, select the new user to be the new owner of the old “admin” user’s content.

By following these steps, website owners can change the default “admin” username in WordPress, making it more difficult for attackers to guess the username and gain access to the website. It’s important to use a strong, unique username and password for all user accounts on a WordPress website to improve the overall security of the website.

Disable File Editing

By default, WordPress allows users with administrative privileges to edit theme and plugin files directly from the WordPress Dashboard. This can be a security risk as an attacker who gains access to the website could make changes to the website’s code, potentially compromising the website.

To disable file editing in WordPress, add the following code to the wp-config.php file:

( 'DISALLOW_FILE_EDIT', true );

This code will prevent anyone with administrative privileges from accessing the theme and plugin editor in the WordPress Dashboard. If changes need to be made to the website’s code, they should be done on a development server and then deployed to the live website.

By disabling file editing in WordPress, website owners can reduce the risk of attackers compromising the website by making changes to the website’s code.

Disable PHP File Execution in WordPress Directories

n WordPress, some directories such as the uploads directory are used to store files that are accessible from the website. By default, these directories can also contain PHP files that can be executed, potentially compromising the website.

To disable PHP file execution in certain WordPress directories, website owners can add the following code to a .htaccess file in the directory:

<Files *.php>
  deny from all
</Files>

This code will prevent PHP files from being executed in the directory, reducing the risk of an attacker compromising the website by executing malicious PHP code. It’s important to only disable PHP file execution in directories that don’t need to execute PHP code, as doing so can break the functionality of the website.

By disabling PHP file execution in certain WordPress directories, website owners can improve the security of the website and reduce the risk of an attacker compromising the website.

Limit Login Attempts

Brute-force attacks on WordPress websites are common, where attackers try to guess the username and password to gain access to the website. To reduce the risk of a brute-force attack succeeding, website owners can limit the number of login attempts for each user account.

There are several WordPress plugins available that can limit login attempts, such as Limit Login Attempts and iThemes Security. These plugins allow website owners to set the maximum number of login attempts before the user account is locked out for a set period of time.

Here’s an example of how to limit login attempts using the Limit Login Attempts plugin:

1. Install the plugin: In the WordPress Dashboard, navigate to Plugins > Add New and search for Limit Login Attempts. Install and activate the plugin.
2. Configure the plugin: Navigate to Settings > Limit Login Attempts to configure the plugin.
3. Set the maximum number of login attempts: Set the maximum number of login attempts before the user account is locked out.
4. Set the lock-out period: Set the length of time that the user account will be locked out after reaching the maximum number of login attempts.

By limiting the number of login attempts for each user account, website owners can reduce the risk of a brute-force attack succeeding. It’s important to use strong, unique usernames and passwords for all user accounts on a WordPress website to further improve the overall security of the website.

Two-factor authentication (2FA)

Two-factor authentication (2FA) adds an extra layer of security to the login process by requiring users to provide two forms of authentication. In addition to a username and password, users are also required to enter a one-time code generated by a mobile app or sent to their phone.

There are several WordPress plugins available that support 2FA, such as Google Authenticator and Authy. These plugins allow website owners to require 2FA for all user accounts or only for specific user roles.

Here’s an example of how to enable 2FA for all user accounts using the Google Authenticator plugin:

1. Install the plugin: In the WordPress Dashboard, navigate to Plugins > Add New and search for Google Authenticator. Install and activate the plugin.
2. Configure the plugin: Navigate to Users > Your Profile to configure the plugin for your user account.
3. Install the Google Authenticator app: Download and install the Google Authenticator app on your smartphone.
4. Set up 2FA: In the WordPress Dashboard, scan the QR code with the Google Authenticator app to set up 2FA for your user account.
5. Enter the one-time code: Each time you log in to the WordPress Dashboard, you’ll be prompted to enter a one-time code generated by the Google Authenticator app.

By enabling 2FA for all user accounts, website owners can add an extra layer of security to the login process and reduce the risk of an attacker gaining access to the website. It’s important to also use strong, unique usernames and passwords for all user accounts on a WordPress website to further improve the overall security of the website.

WordPress Database Prefix

The database prefix is the string of characters that prefixes the table names in the WordPress database. By default, WordPress uses “wp_” as the database prefix. Attackers can use this information to target specific tables in the database, so it’s recommended to change the database prefix to something more secure.

Here’s an example of how to change the database prefix in WordPress:

1. Backup your website: Before making any changes to the database, it’s important to backup your website.
2. Access the database: You can access the database using a tool such as phpMyAdmin, which is often provided by your web host.
3. Change the prefix: In the database, locate the wp_options table and change the prefix to something unique, such as “wpx_”.
4. Update the wp-config.php file: In the WordPress installation directory, locate the wp-config.php file and update the following line of code with the new database prefix:

$table_prefix = 'wpx_';

5. Replace all instances of the old prefix in the database: Use a tool such as the Better Search Replace plugin to replace all instances of the old prefix with the new prefix in the database.
6. Test the website: After making these changes, test the website to make sure everything is working correctly.

By changing the database prefix, website owners can reduce the risk of an attacker gaining access to the WordPress database. It’s important to always backup your website before making any changes to the database.

Password Protect Login Page

Password protecting the WordPress admin and login page adds an extra layer of security to the website by requiring users to enter a password before accessing the WordPress Dashboard or the login page.

Here’s an example of how to password protect the WordPress admin and login page using the .htaccess file:

1. Access the .htaccess file: The .htaccess file is located in the root directory of the WordPress installation. You can access the file using an FTP client or the File Manager in cPanel.
2. Add the following code to the .htaccess file:

<FilesMatch "wp-login.php">
AuthType Basic
AuthName "Restricted Area"
AuthUserFile /full/path/to/.htpasswd
Require valid-user
</FilesMatch>

3. Create the .htpasswd file: The .htpasswd file contains the username and password for the user who will be able to access the WordPress Dashboard and login page.
4. Add the following code to the .htpasswd file:

username:encryptedpassword

5. Update the paths in the .htaccess file: Update the path to the .htpasswd file in the .htaccess file to match the location of the file on your server.
6. Test the website: After making these changes, test the website to make sure everything is working correctly.

By password protecting the WordPress admin and login page, website owners can reduce the risk of an attacker gaining access to the WordPress Dashboard or login page. It’s important to use a strong, unique password for the user who will be able to access the WordPress Dashboard and login page.

Disable Directory Indexing

Directory indexing and browsing allows users to see a list of files and directories in a directory if there is no index file (e.g. index.html) present. This can provide attackers with information about the structure of the website, which can be used to plan an attack.

To disable directory indexing and browsing in WordPress, you can add the following code to the .htaccess file in the root directory of the website:

Options -Indexes

This code will prevent users from seeing a list of files and directories in the website if there is no index file present.

It’s important to keep in mind that disabling directory indexing and browsing can also prevent users from accessing content that you want them to access. Before making any changes to the .htaccess file, it’s recommended to backup the website to ensure that you can revert the changes if necessary.

Disable XML-RPC Port in WordPress

XML-RPC is a feature in WordPress that allows remote posting and other features to be performed through XML-RPC APIs. While XML-RPC is useful for certain applications, it can also be a security risk, as it can be used to perform brute force attacks, DDoS attacks, and other types of attacks.

To disable XML-RPC in WordPress, you can add the following code to the functions.php file in your WordPress theme:

add_filter('xmlrpc_enabled', '__return_false');

Alternatively, you can install a plugin that disables XML-RPC, such as the Disable XML-RPC plugin.

By disabling XML-RPC in WordPress, you can reduce the attack surface of the website and prevent attackers from exploiting vulnerabilities in XML-RPC to gain unauthorized access to the website. However, it’s important to note that disabling XML-RPC can also break certain features of your website that rely on XML-RPC, so it’s recommended to test the website after making this change to ensure that everything is working as expected.
