How do I secure my WordPress site from attacks?

Introduction

In this article, you’ll learn how to secure your WordPress website against common attacks such as brute-force login attempts, malware injections, and unauthorised access. Following these steps will help protect your data and maintain your site’s performance.

Step 1: Keep WordPress, Themes, and Plugins Updated

Always ensure that your WordPress core, themes, and plugins are up to date. Updates often include important security patches that protect against known vulnerabilities.

Log in to your WordPress Dashboard.
Go to Dashboard → Updates.
Click Update Now for WordPress, plugins, or themes that have new versions available

Step 2: Use Strong Login Credentials

Avoid using simple usernames like “admin” and weak passwords.

Create a unique username.
Use a strong password containing uppercase, lowercase, numbers, and special characters.
Change your password regularly.

Step 3: Enable Two-Factor Authentication (2FA)

Two-factor authentication adds an extra security layer to your login process.

Install a plugin such as Wordfence Security or Google Authenticator.
Go to Users → Your Profile and enable 2FA.
Scan the QR code with your authentication app.

Step 4: Install a Security Plugin

Security plugins help detect malware, block suspicious IPs, and enforce strong login rules.

Recommended plugins:

Wordfence Security
iThemes Security
Sucuri Security

Go to Plugins → Add New.

Search for a security plugin and click Install Now, then Activate.

Step 5: Use SSL (HTTPS)

An SSL certificate encrypts data transferred between your website and visitors.

Log in to your hosting control panel.
Open the SSL/TLS section.
Enable Free SSL or install your own certificate.

Step 6: Limit Login Attempts

Limiting login attempts helps prevent brute-force attacks.

Install a plugin such as Limit Login Attempts Reloaded.
Configure the maximum number of failed attempts allowed.

Step 7: Regularly Back Up Your Site

Backups ensure that your website can be restored quickly after a security breach.

Install a backup plugin like UpdraftPlus or Jetpack Backup.
Set automatic backups (daily or weekly).
Store backups in a secure location such as Google Drive or Dropbox.

Step 8: Set Correct File Permissions

Incorrect file permissions can allow hackers to modify or upload malicious files.

Access your site via File Manager or FTP.
Ensure permissions are set for folder 755 and for files 644

Step 9: Monitor for Malware and Suspicious Activity

Scan your website regularly for malware and unusual activity.

Use your security plugin’s scan feature.
Review logs for unauthorized login attempts or changes.
Remove inactive users and unused plugins.

Conclusion

Securing your WordPress site is an ongoing process that combines regular updates, strong credentials, reliable security plugins, and proactive monitoring. By following best practices and taking preventive measures, you can significantly reduce the risk of attacks and ensure your website remains safe, reliable, and trustworthy for your users.
