WordPress is one of the most popular website platforms in the world. Because of its popularity, it is also a common target for hackers. Protecting your WordPress site from attacks is essential to keep your data safe and maintain the trust of your visitors.
In this guide, you will learn practical steps to secure your WordPress website and reduce the risk of hacking.
1. Keep WordPress Core, Themes, and Plugins Updated
One of the easiest ways hackers gain access to websites is by exploiting outdated software. WordPress regularly releases updates for its core system, themes, and plugins to fix security vulnerabilities and improve functionality. When you delay updating, you leave your site exposed to known security flaws that hackers can exploit easily.
Updating also ensures compatibility between your site’s components, reducing the chance of conflicts that might cause errors or downtime. Many hosting providers offer automatic updates, but if yours doesn’t, make a habit of checking and applying updates regularly. Always backup your site before major updates to avoid data loss.
2. Use Strong Usernames and Passwords
Using default usernames like “admin” is risky because hackers know these are common targets. Choosing a unique username makes it harder for attackers to guess your login details. Strong passwords are equally important. They should be a mix of uppercase and lowercase letters, numbers, and special characters.
Avoid using easy-to-guess information such as birthdays or simple words. Password managers can help you generate and store complex passwords securely. Also, consider changing your passwords periodically to maintain security. Never share your login credentials with anyone you don’t fully trust.
3. Limit Login Attempts
Hackers often use automated tools to try many password combinations in a short time. This technique is called a brute force attack. Limiting the number of login attempts from the same IP address helps block these attacks by locking out users after a few failed tries.
Plugins like Login LockDown or Limit Login Attempts Reloaded make it easy to set these limits. You can customize the number of attempts allowed and the lockout duration. This simple step can drastically reduce the chance of unauthorized access without affecting legitimate users.
4. Enable Two-Factor Authentication
Two-factor authentication (2FA) adds an extra layer of protection beyond just a username and password. When enabled, it requires users to provide a second form of identification, such as a unique code sent to their mobile phone or generated by an authentication app.
Even if a hacker obtains your password, they cannot access your account without this second verification step. Many security plugins like Wordfence or standalone apps such as Google Authenticator allow easy integration of 2FA into your WordPress login process. This greatly improves your site’s security with minimal effort.
5. Use a Security Plugin
Security plugins help monitor your website for suspicious activity and prevent attacks before they happen. They provide features such as malware scanning, firewall protection, login security, and real-time threat detection.
Popular security plugins like Wordfence, Sucuri Security, and iThemes Security are widely trusted and regularly updated to protect against the latest threats. Installing and configuring a security plugin gives you peace of mind, knowing your site is constantly being watched for potential issues.
6. Change the Default Login URL
By default, WordPress login pages are found at yoursite.com/wp-admin or yoursite.com/wp-login.php. Hackers know these URLs and often target them with automated attacks. Changing your login page URL to something unique and hard to guess can prevent many unauthorized login attempts.
Plugins like WPS Hide Login allow you to change the URL easily without affecting your site’s functionality. Make sure to choose a memorable but not obvious new URL, and keep it private to avoid locking yourself out. This step adds a layer of obscurity to your site’s security.
7. Use SSL Certificate
An SSL certificate encrypts the data transferred between your visitors and your website, such as login credentials, personal information, or payment details. This encryption protects sensitive data from being intercepted by hackers during transmission.
Using HTTPS instead of HTTP also builds trust with your visitors, as browsers show a padlock icon indicating a secure connection. Additionally, Google gives ranking preference to HTTPS sites, improving your SEO. Many hosting providers offer free SSL certificates through Let’s Encrypt, making it easy to enable.
8. Backup Your Website Regularly
Regular backups are critical because they allow you to restore your website quickly if it gets hacked, corrupted, or if something goes wrong during updates. Backups should include your database, themes, plugins, and media files.
Use backup plugins like UpdraftPlus or BackupBuddy to schedule automatic backups on a daily or weekly basis depending on your update frequency. Store these backups securely offsite, such as in cloud storage or an external drive. This ensures you always have a clean version of your website ready to restore.
9. Set Correct File Permissions
File permissions control who can read, write, or execute files on your server. Incorrect permissions can make your site vulnerable by allowing hackers to access or modify important files.
Typically, directories should be set to 755 and files to 644. These settings allow your site to function correctly while preventing unauthorized access. You can adjust permissions via your hosting control panel or FTP client. If you’re unsure, ask your hosting provider for guidance to avoid accidentally breaking your site.
10. Disable File Editing in the Dashboard
WordPress allows administrators to edit theme and plugin files directly from the dashboard. While this can be convenient, it poses a risk if a hacker gains access to your admin account, as they can insert malicious code through this editor.
To prevent this, disable the file editor by adding the following line to your wp-config.php file:
phpCopyEditdefine('DISALLOW_FILE_EDIT', true);
This simple step protects your site by removing the ability to modify files through the dashboard, limiting damage if your account is compromised.
Conclusion
Securing your WordPress site from hackers does not have to be complicated. By following these simple but effective steps, you can greatly reduce your risk and protect your website from common attacks. Keep your software updated, use strong passwords, enable two-factor authentication, and regularly back up your data.
Your website and visitors will thank you for the extra security. If you want help implementing these security measures or need advice on managing your WordPress site, feel free to reach out.
