Secure Your WordPress Site: A Guide to Protecting Your Online Presence

Introduction

WordPress, as one of the most popular content management systems, powers millions of websites worldwide. Unfortunately, its popularity also makes it a target for cyberattacks. By following the steps outlined in this guide, you can significantly enhance the security of your WordPress site.

Save Your Important WordPress Files for Backup

Before implementing any security measures, it’s essential to have reliable backups of your WordPress files and databases. In the event of a security breach or data loss, having backups ensures that you can quickly restore your site to its previous state. There are numerous backup plugins available, such as UpdraftPlus and BackupBuddy, which automate the backup process.

Restricting Access to Login Page

To prevent unauthorized access to your WordPress login page (wp-admin/wp-login), consider implementing IP address or country-based restrictions. This can be achieved through the use of plugins like “WPS Hide Login” or by configuring server rules using .htaccess files.

Example .htaccess code to restrict access based on IP:

<Files wp-login.php>
  order deny,allow
  allow from Your.IP.Address.Here
  deny from all
</Files>

Adding a Custom Field to the WordPress Login Page

Enhance your WordPress login page’s security by adding a custom field. This could be an additional layer of authentication, such as a unique code sent to the user’s email upon login, ensuring that only authorized users can access the dashboard.

Example code to add a custom field to the login page:

function add_custom_field_to_login() {
    echo '<input type="text" name="custom_field" placeholder="Enter your custom code">';
}
add_action('login_form', 'add_custom_field_to_login');

Example code to validate the custom field:

function validate_custom_field($user, $username, $password) {
    if (empty($_POST['custom_field']) || $_POST['custom_field'] !== 'your_custom_code') {
        return new WP_Error('authentication_failed', __('<strong>ERROR</strong>: Invalid custom code.'));
    }
    return $user;
}
add_filter('authenticate', 'validate_custom_field', 10, 3);

Implementing Google reCaptcha v2

Combat automated login attempts and brute force attacks by integrating Google reCaptcha v2 into your WordPress login page. The “Google Captcha (reCaptcha) by BestWebSoft” plugin simplifies this process, effectively reducing the risk of malicious login attempts.

Example code to add reCaptcha to login page:

function add_recaptcha_to_login_page() {
    echo '<div class="g-recaptcha" data-sitekey="your-site-key"></div>';
}
add_action('login_form', 'add_recaptcha_to_login_page');

Getting Notified of Dashboard Access

Stay vigilant by setting up notifications whenever someone accesses your WordPress dashboard. This can be achieved through email alerts or push notifications using plugins like “Login Notifier.”

Example code to send an email notification on dashboard access:

function send_dashboard_access_notification($user_login, $user) {
    $to = 'admin@example.com';
    $subject = 'Dashboard Access Notification';
    $message = "User {$user_login} accessed the WordPress dashboard.";
    wp_mail($to, $subject, $message);
}
add_action('wp_login', 'send_dashboard_access_notification', 10, 2);

Securing Your Database

Your WordPress database holds crucial information, making it a prime target for attackers. Change the default database table prefix during installation, and ensure your database credentials are strong and unique. Regularly optimize and repair your database using plugins like “WP-Optimize.”

Protect Your Database with Prefix Change: During WordPress installation, modify the default database table prefix (usually “wp_”) to something unique. This prevents hackers from easily targeting your database tables.

Example code to change the database table prefix:

$table_prefix = 'customprefix_';

Protecting WordPress Files with Simple Measures

Several essential WordPress files, like wp-config.php and .htaccess, need extra protection. By placing these files outside of the public HTML directory, you reduce their vulnerability to direct access.

Example code to move wp-config.php:

if (!defined('ABSPATH')) {
    define('ABSPATH', dirname(__FILE__) . '/');
}
require_once(ABSPATH . 'custom-folder/wp-config.php');

Understanding File Permissions

File permissions play a vital role in security. Configure the correct permissions for your WordPress files and directories to prevent unauthorized access. Generally, directories should have a permission of 755, and files should have a permission of 644.

Example code to set file permissions:

find /path/to/your/wordpress/installation -type d -exec chmod 755 {} \;
find /path/to/your/wordpress/installation -type f -exec chmod 644 {} \;

Concealing Your WordPress Installation

Disguising the fact that your site is built with WordPress can deter potential attackers. Modify the default folder and file names, and avoid displaying the WordPress version publicly.

Basic Precautions

Practice basic security hygiene, such as using strong passwords, regularly updating themes and plugins, and limiting user privileges. The “All In One WP Security & Firewall” plugin can help you implement these precautions.

Resolving Internal Server Errors

Encountering an internal server error or critical error can be stressful. Common culprits include plugin conflicts and PHP memory limits. Disable recently added plugins and increase your PHP memory limit to troubleshoot these issues.

Restoring Your Website from Backup

In case of a security breach or significant website issues, restoring from backup is essential. Follow the backup plugin’s instructions to restore your website to its previous state.

Cleaning an Infected WordPress Website

If your website gets infected, take immediate action. Manually remove malicious code from files, scan your site for malware, and consider using a reputable security plugin like “Sucuri Security.”

Making the Website Online Again

After cleaning an infected website, ensure it’s safe to go live. Re-scan your site using security plugins and tools to verify its security status before making it accessible to users.

Additional Security Measures

• Disable XML-RPC: XML-RPC can be exploited for brute force attacks. Disable it using plugins like “Disable XML-RPC” to reduce vulnerability.
• Disable PHP Error Reporting: In a production environment, turn off PHP error reporting to prevent sensitive information from being exposed.
• Prevent Image Hotlinking: Prevent other websites from directly linking to your images by adding code to your .htaccess file.
• Disable File Editor: Disable the WordPress file editor to prevent attackers from modifying theme and plugin files from within the dashboard.
• Protect wp-config File: Protect your wp-config.php file by placing it outside the public HTML directory and adding security rules to your .htaccess file.

Hide WordPress from Bots, Attackers, and Theme Detector Sites

Hiding your WordPress installation from bots, attackers, and theme detector sites can be achieved by modifying the server configuration. This involves denying access to specific files and directories that might reveal your site’s CMS.

Example code to deny access to sensitive files

<FilesMatch "(^\.|wp-config\.php|readme\.html|license\.txt)">
    Order allow,deny
    Deny from all
</FilesMatch>

Alternative Way to Change Default WordPress Login URL

You can change the default WordPress login URL without using plugins by adding code to your theme’s functions.php file.

Example code to change the login URL without plugins:

function custom_login_url() {
    return home_url('my-login-url');
}
add_filter('login_url', 'custom_login_url');
