When it comes to applying security headers in WordPress, most people think it's complicated or only for advanced users. The truth is, you don't need to be a developer to set them up — but doing so can make your site significantly more secure against common web threats.

Here's how to do it without getting too technical.

What Are Security Headers and Why They Matter

Security headers are part of the HTTP response that browsers receive when loading a website. These headers tell the browser how to behave when handling your site's content. For example, they can help prevent cross-site scripting (XSS), clickjacking, and MIME type sniffing.

Without proper headers, your WordPress site could be more vulnerable to attacks, even if everything else is locked down.

Common headers you should consider:

• Content-Security-Policy
• X-Content-Type-Options: nosniff
• X-Frame-Options: DENY or SAMEORIGIN
• X-XSS-Protection: 1; mode=block
• Strict-Transport-Security (HSTS)

These aren't plugins — they're server-level settings, which means they need to be configured outside the WordPress dashboard.

How to Add Security Headers in WordPress

There are a few ways to apply these headers depending on your setup:

1. Using Your Web Server Configuration

If you have access to your server configuration files (like Apache's .htaccess or Nginx config), this is the most reliable method.

For Apache:

 <IfModule mod_headers.c>
    Header set X-Content-Type-Options "nosniff"
    Header set X-Frame-Options "DENY"
    Header set X-XSS-Protection "1; mode=block"
    Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"
</IfModule>

For Nginx:

 add_header X-Content-Type-Options "nosniff";
add_header X-Frame-Options "DENY";
add_header X-XSS-Protection "1; mode=block";
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload";

Make sure mod_headers is enabled in Apache and that you reload the server config after changes.

2. Using a Security Plugin

If you're not comfortable editing server files, there are plugins like Wordfence , iThemes Security , or HTTP Headers that let you configure some of these headers from within WordPress.

Just keep in mind:

• Not all plugins support every header
• Some may not update headers dynamically as needed
• Always test after enabling to avoid breaking your site

3. Through a CDN

If you use Cloudflare, Sucuri, or another CDN, many offer built-in options to set security headers. This is often the easiest way if you want to manage headers globally without touching server files.

For example, in Cloudflare:

• Go to SSL/TLS > HTTP Strict Transport Security
• Enable HSTS with subdomains and preload options
• Under Rules > Response Headers , create custom rules for other headers

Test and Monitor Your Headers

Once applied, it's important to verify your headers are working correctly.

You can use tools like:

• SecurityHeaders.com
• Chrome DevTools (Network tab > Headers)
• Hardenize

These will scan your site and grade your implementation. Aim for at least an A rating, though getting an A is possible with full HSTS, CSP, and other protections in place.

Also, remember:

• Don't enable headers you don't understand
• Content-Security-Policy can break your site if not configured properly
• Always back up before making changes

Final Thoughts

Applying security headers in WordPress isn't hard, but it does require a bit of care. Whether you go through your server config, a plugin, or your CDN, just make sure you test everything afterward. It's one of those things that doesn't take long but adds a solid layer of protection.

And honestly, once it's done right, you can forget about it — until next time you review your site's security posture.

基本上就這些。
