WordPress is the most popular website platform in the world, powering over 40% of all websites. Its user-friendly interface and powerful features make it an ideal choice for businesses, bloggers, and online stores. However, with this popularity comes a major concern: security. WordPress websites are prime targets for hackers because of their widespread use and common vulnerabilities.
In this blog post, we’ll guide you through the basics of WordPress security and provide practical tips and best practices to protect your website from potential cyber threats. By implementing these measures, you’ll significantly reduce the risk of a successful hack and keep your website and data safe.
- Keep WordPress Core, Themes, and Plugins Updated
The first line of defense in securing your WordPress site is keeping everything up to date. WordPress regularly releases updates to patch security vulnerabilities and add new features. If you neglect to install these updates, your website becomes vulnerable to known exploits.
Why updates matter:
• WordPress Core Updates: The core WordPress files are frequently updated to fix security bugs and improve overall performance. New versions often address discovered security issues.
• Themes and Plugins: Themes and plugins can also contain vulnerabilities, and developers issue updates to fix bugs and improve security. Outdated themes and plugins can be an easy entry point for hackers.
How to keep your site updated:
• Turn on automatic updates for WordPress core and plugins (from the settings page).
• Regularly check for updates in your dashboard and apply them promptly.
• Use the “Easy Updates Manager” plugin to manage and automate updates for themes, plugins, and WordPress itself. - Use Strong Passwords and Two-Factor Authentication (2FA)
Weak passwords are one of the most common ways hackers gain access to WordPress sites. Many users still rely on simple, easy-to-guess passwords like “admin” or “123456.” Strong passwords are essential for both admin and user accounts.
Best practices for passwords:
• Use complex passwords: Combine uppercase and lowercase letters, numbers, and special characters. Aim for at least 12 characters.
• Avoid default usernames: “Admin” is the most commonly targeted username for brute force attacks, so create a custom username.
• Password manager: Consider using a password manager like LastPass or Dashlane to generate and store strong, unique passwords for all your accounts.
Two-Factor Authentication (2FA):
2FA adds an extra layer of protection by requiring users to provide a second form of authentication (like a code sent to your phone) in addition to the password.
How to enable 2FA:
• Install a plugin like Google Authenticator or Wordfence to add 2FA to your WordPress login process.
• Enable 2FA for both admins and regular users for enhanced security. - Install a WordPress Security Plugin
Using a WordPress security plugin is one of the best ways to enhance your website’s defense against hackers. These plugins offer a range of features to protect your site, including malware scanning, firewall protection, and login attempt monitoring.
Top WordPress security plugins:
• Wordfence Security: Offers a comprehensive suite of security tools, including firewall protection, malware scanning, and login attempt monitoring.
• Sucuri Security: Provides malware scanning, file integrity monitoring, and website firewall protection.
• iThemes Security: Known for its easy setup and features like two-factor authentication, file change detection, and brute force protection.
Security plugins can help protect your site automatically and notify you if anything unusual occurs. - Regularly Back Up Your Website
Website backups are crucial. If your WordPress site is hacked, or if there’s a server issue, a backup allows you to quickly restore your website to its previous state.
Backup Best Practices:
• Use a reliable backup plugin: Plugins like UpdraftPlus, BackupBuddy, or Jetpack Backup can help you schedule automatic backups.
• Store backups off-site: Don’t store backups on your server in case the server itself gets compromised. Use cloud storage options like Google Drive, Dropbox, or Amazon S3 to store your backups securely.
• Test your backups: Ensure that your backups are working properly by periodically restoring them to a test environment.
Having regular backups ensures you can recover from any security incident quickly and with minimal downtime. - Secure Your WordPress Login Page
The WordPress login page is a frequent target for brute force attacks, where hackers attempt to guess your password by trying numerous combinations. By securing this page, you can protect your site from these types of attacks.
How to secure the login page:
• Change the login URL: The default WordPress login URL is “yourdomain.com/wp-admin” or “yourdomain.com/wp-login.php.” Changing this URL makes it more difficult for attackers to find.
o Use a plugin like WPS Hide Login to change the login page URL to something custom.
• Limit login attempts: Brute force attacks rely on multiple login attempts. Limiting the number of failed login attempts will block malicious users from guessing passwords.
o Plugins like Limit Login Attempts Reloaded can help you implement this feature.
• Use CAPTCHA or reCAPTCHA: Adding a CAPTCHA or Google reCAPTCHA to the login page ensures that only humans can attempt to log in. This helps prevent automated attacks.
o Plugins like Google Captcha (reCAPTCHA) or WP-reCAPTCHA Integration can add this feature. - Set Proper File Permissions
WordPress file permissions determine who can read, write, and execute files and directories on your server. Improper file permissions can expose your website to attackers, who may gain unauthorized access to sensitive files.
Best practices for file permissions:
• Set the correct file and folder permissions: WordPress recommends using the following permissions:
o Files: 644
o Directories: 755
o wp-config.php: 400 or 440 (for extra security)
• Avoid using 777 permissions: Never set file or directory permissions to 777, as this allows anyone to read, write, and execute the file, which is a major security risk.
You can adjust these permissions using your hosting control panel (cPanel) or an FTP client. - Disable Directory Listing
Directory listing occurs when a server is configured to display a list of files in a directory. If directory listing is enabled, hackers can easily see all the files in a folder, including potentially sensitive files like backups or configuration files.
How to disable directory listing:
• Add the following line to your website’s .htaccess file to disable directory listing:
• Options -Indexes
• This will prevent anyone from being able to view files in directories where no index file (e.g., index.php, index.html) is present. - Implement a Web Application Firewall (WAF)
A Web Application Firewall (WAF) acts as a barrier between your website and malicious traffic. It filters out harmful traffic and only allows legitimate visitors to access your site.
How to use a WAF:
• Cloudflare: A popular, free service that includes a built-in WAF. Cloudflare also provides protection against DDoS attacks, bot attacks, and other common threats.
• Sucuri Firewall: A premium WAF that offers additional security features, including malware detection, blacklist monitoring, and DDoS protection.
A WAF helps block a wide range of attacks before they even reach your website, keeping your data secure. - Monitor User Activity
Tracking user activity on your WordPress site can help you spot suspicious behavior before it leads to a security breach. You can monitor login attempts, file changes, and other actions taken by users on your site.
Plugins to monitor user activity:
• WP Activity Log: Tracks user activity and records actions like login attempts, post/page edits, and plugin updates. This helps you detect unauthorized actions and quickly respond.
• Simple History: Displays a log of all recent changes to your website, including user logins, content changes, and plugin activations.
By monitoring user behavior, you can identify potential security threats and act quickly to mitigate them. - Disable XML-RPC If Not Needed
XML-RPC is a WordPress feature that allows external applications to interact with your site. While useful for some applications (like mobile apps), it can also be a target for hackers.
How to disable XML-RPC:
• If you don’t use XML-RPC, it’s best to disable it to prevent brute-force attacks.
• You can disable it via a plugin like Disable XML-RPC or by adding a line of code to your .htaccess file.
Conclusion
Securing your WordPress website doesn’t have to be a daunting task. By following these basic WordPress security best practices, you can significantly reduce the risk of being hacked. Regularly updating your site, using strong passwords, installing a security plugin, and implementing additional measures like backups and firewalls will protect your website from most common threats.
Remember, security is an ongoing process. Stay vigilant, monitor your website for any unusual activity, and keep your WordPress site protected. By taking these precautions, you’ll ensure that your website remains secure and your visitors’ data stays safe.
