Securing your WordPress website is a critical task that requires attention to detail and ongoing vigilance. This WordPress Security Checklist will help you to Secure Your Website and protect it from potential security and cyber threats and vulnerabilities online.
1. Choose a Secure Hosting Provider
Why It Matters
A secure hosting provider is your first line of defense. They should offer robust security measures including firewalls, malware scanning, and intrusion detection.
What to Look For
- Reputation: Check reviews and reputation in the industry.
- Security Features: Look for providers offering SSL certificates, daily backups, and DDoS protection.
- Support: 24/7 support is crucial for addressing any issues promptly.
2. Keep WordPress Core, Themes, and Plugins Updated
Why It Matters
Outdated software is one of the most common vulnerabilities exploited by hackers.
How to Do It
- Automatic Updates: Enable automatic updates for minor WordPress core updates.
- Manual Checks: Regularly check and update themes and plugins.
- Update Notifications: Use plugins like WP Updates Notifier to stay informed about updates.
3. Use Strong Passwords and Change Them Regularly
Why It Matters
Weak passwords can be easily guessed or cracked, giving hackers access to your site.
How to Do It
- Strong Passwords: Use a mix of upper and lower case letters, numbers, and special characters.
- Password Managers: Use tools like LastPass or 1Password to generate and store strong passwords.
- Regular Changes: Change passwords every few months and avoid reusing passwords across multiple sites.
4. Implement Two-Factor Authentication (2FA)
Why It Matters
2FA adds an additional layer of security by requiring a second form of verification.
How to Do It
- Plugins: Use plugins like Google Authenticator or Two Factor Authentication.
- SMS Verification: Some plugins offer SMS verification as a 2FA method.
- Backup Codes: Ensure you have backup codes in case you lose access to your 2FA device.
5. Limit Login Attempts
Why It Matters
Limiting login attempts helps prevent brute force attacks where hackers try multiple password combinations.
How to Do It
- Plugins: Use plugins like Limit Login Attempts Reloaded or WP Limit Login Attempts.
- Settings: Configure the plugin to lock out users after a certain number of failed attempts and notify the admin of these attempts.
6. Use Security Plugins
Why It Matters
Security plugins offer comprehensive protection including malware scanning, firewalls, and activity monitoring.
Recommended Plugins
- Wordfence: Provides endpoint firewall and malware scanning.
- Sucuri Security: Offers security activity auditing, file integrity monitoring, and remote malware scanning.
- iThemes Security: Enhances security with features like file change detection, 404 detection, and strong password enforcement.
7. Regular Backups
Why It Matters
Backups are essential for recovering your site in case of data loss or a security breach.
How to Do It
- Plugins: Use plugins like UpdraftPlus, BackWPup, or VaultPress.
- Schedule: Set up regular, automated backups.
- Off-Site Storage: Store backups on remote servers or cloud services like Google Drive, Dropbox, or Amazon S3.
8. Secure Your wp-config.php File
Why It Matters
The wp-config.php file contains critical configuration settings and database information.
How to Do It
- Move wp-config.php: Move the file to a directory one level above the WordPress root directory.
- File Permissions: Set the file permissions to 400 or 440 to prevent unauthorized access.
9. Change the Default “admin” Username
Why It Matters
Using “admin” as a username is common and makes it easier for hackers to guess.
How to Do It
- Create a New Admin User: Create a new user with admin privileges.
- Delete the Default Admin: Log in with the new admin user and delete the old “admin” account.
- Attribute Content: Assign all posts and content to the new user when deleting the old “admin” user.
10. Use HTTPS and SSL
Why It Matters
HTTPS encrypts data transferred between the user’s browser and your server, protecting sensitive information.
How to Do It
- SSL Certificate: Obtain an SSL certificate from your hosting provider or services like Let’s Encrypt.
- HTTPS Redirection: Use plugins like Really Simple SSL to force HTTPS on your site.
- Verify: Check your site for mixed content errors to ensure all elements are loaded securely.
11. Hide Your WordPress Version
Why It Matters
Knowing the WordPress version can help attackers exploit known vulnerabilities.
How to Do It
- Remove Meta Tag: Add the following code to your theme’s functions.php file:php
remove_action('wp_head', 'wp_generator'); - Security Plugins: Some security plugins also offer options to hide your WordPress version.
12. Disable File Editing
Why It Matters
By default, WordPress allows administrators to edit PHP files directly from the dashboard, which can be a security risk.
How to Do It
- wp-config.php: Add the following line to your wp-config.php file to disable file editing:php
define('DISALLOW_FILE_EDIT', true);
13. Restrict Access to wp-admin
Why It Matters
Restricting access to the wp-admin directory reduces the risk of unauthorized users accessing sensitive areas of your site.
How to Do It
- .htaccess: Use the .htaccess file to restrict access by IP address:apache
<Files wp-login.php>
order deny,allow
Deny from all
Allow from [your_ip_address]
</Files>
14. Monitor Your Site Activity
Why It Matters
Monitoring site activity helps you detect and respond to suspicious behavior promptly.
How to Do It
- Plugins: Use plugins like WP Security Audit Log or Simple History to track user activity.
- Alerts: Set up email notifications for critical actions like failed login attempts or changes to user roles.
15. Harden Your Database Security
Why It Matters
Your WordPress database contains all your site’s data, making it a prime target for attackers.
How to Do It
- Change Database Prefix: Change the default
wp_prefix to something unique during installation. - Database User Permissions: Use a database user with limited permissions for your WordPress site.
- Regular Backups: Ensure your database is included in your regular backup schedule.
16. Disable XML-RPC
Why It Matters
XML-RPC can be exploited for DDoS attacks and brute force attacks.
How to Do It
- Disable XML-RPC: Add the following code to your .htaccess file:apache
# Block WordPress xmlrpc.php requests
<Files xmlrpc.php>
order deny,allow
deny from all
allow from [your_ip_address]
</Files> - Plugins: Use plugins like Disable XML-RPC to turn off this feature completely.
17. Use a Web Application Firewall (WAF)
Why It Matters
A WAF helps protect your site from common threats by filtering and monitoring HTTP traffic between your web application and the internet.
How to Do It
- Service Providers: Use services like Sucuri, Cloudflare, or Wordfence that offer WAFs.
- Configuration: Ensure the WAF is properly configured to match your site’s needs.
18. Implement Content Security Policy (CSP)
Why It Matters
CSP helps prevent a range of attacks including Cross-Site Scripting (XSS) and data injection attacks.
How to Do It
- Add CSP Header: Add a Content Security Policy header to your site’s .htaccess or server configuration:apache
Header set Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline' 'unsafe-eval'; style-src 'self' 'unsafe-inline'; img-src 'self' data:; font-src 'self'; connect-src 'self'; frame-src 'none';" - Test and Refine: Test your CSP implementation using tools like Google’s CSP Evaluator and adjust as needed.
19. Regularly Scan for Malware
Why It Matters
Regular malware scans help you detect and remove malicious code from your site.
How to Do It
- Plugins: Use security plugins like Wordfence, Sucuri, or MalCare that offer malware scanning.
- Online Tools: Use online services like VirusTotal or Sucuri SiteCheck for additional scans.
20. Educate Your Users
Why It Matters
User awareness is crucial for maintaining site security. Educated users are less likely to fall for phishing scams or make security mistakes.
How to Do It
- Training Sessions: Conduct regular security training sessions for your team.
- Resources: Provide access to security resources and best practices.
- Policies: Establish clear security policies and procedures for all users.
Conclusion
Securing your WordPress site is an ongoing process that involves multiple layers of defense.
