The setting server_tokens off isn't directly found within the WordPress administration panel. This is because it's a server-level directive, not a WordPress-specific setting. It's configured within your web server's configuration files (e.g., Apache's .htaccess or Nginx's configuration file). WordPress runs on top of the web server; it doesn't control the server's core functionality.
Understanding why you might want this setting is crucial before diving into how to implement it. server_tokens off hides information about your web server software (like Apache version or Nginx version) from clients who request your site. This can be a minor security enhancement, as it reduces the surface area for potential attackers who might exploit known vulnerabilities tied to specific server versions.
However, it's important to note that server_tokens off alone is not a robust security measure. It's a small piece of a much larger security puzzle. Relying solely on this setting for security is a dangerous oversimplification. Strong security practices demand a multi-layered approach involving regular updates, strong passwords, robust plugins (only reputable ones!), and proactive monitoring.
Finding and Modifying Your Server Configuration
The precise method for implementing server_tokens off depends on your web server:
Apache
If you're using Apache, you'll typically need to edit your .htaccess file. This file is usually located in your WordPress root directory (the same directory where wp-config.php resides). Caution: Incorrectly editing this file can break your website. Back up your .htaccess file before making any changes.
To add the directive, add this line to your .htaccess file:
ServerTokens Prod
This achieves a similar effect to server_tokens off (which isn't directly supported in all Apache versions through .htaccess). ServerTokens Prod sets the server tokens to a minimal, production-ready setting.
Important Considerations for Apache:
- Access: You need FTP access or shell access to your server to edit the
.htaccessfile. - Permissions: Ensure the file has the correct permissions.
- .htaccess enabled: Your hosting provider needs to have
.htaccessfunctionality enabled.
Nginx
For Nginx, the configuration is handled differently. You'll need to modify your main Nginx configuration file (often located at /etc/nginx/nginx.conf or a similar path, depending on your server setup). The exact location varies greatly depending on the hosting provider and server configuration. You'll likely need to find the server block corresponding to your WordPress installation and add the following within that block:
server_tokens off;
Important Considerations for Nginx:
- Root access or permissions: Editing Nginx configurations requires significant server access and permissions; it often requires root privileges.
- Restart Nginx: After making changes, you'll need to restart the Nginx service for the changes to take effect.
Beyond server_tokens off: A Holistic Approach to WordPress Security
Remember that securing your WordPress site goes beyond a single server directive. Here are some crucial best practices:
- Keep WordPress Core, Themes, and Plugins Updated: Regularly update all software components to patch security vulnerabilities.
- Strong Passwords: Use long, complex, and unique passwords for all your accounts.
- Two-Factor Authentication (2FA): Enable 2FA wherever possible for added security.
- Regular Backups: Regularly back up your entire WordPress installation to safeguard against data loss or attacks.
- Security Plugins: Use reputable security plugins (after thorough research and due diligence) to enhance protection.
- Web Application Firewall (WAF): Consider a WAF to protect against common web attacks.
- HTTPS: Ensure your website uses HTTPS to encrypt communication between your website and visitors.
By combining these practices with the proper server configuration, you can significantly improve your WordPress site's security posture. However, remember that absolute security is an elusive goal; continuous vigilance and adaptation are necessary.
