class=\"wp-block-paragraph\">If your WordPress website runs on Apache, security headers can be configured through <code>.htaccess<\/code>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The exact configuration depends on your hosting environment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A basic example might look like:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>&lt;IfModule mod_headers.c&gt;\n    Header always set X-Content-Type-Options \"nosniff\"\n    Header always set Referrer-Policy \"strict-origin-when-cross-origin\"\n    Header always set X-Frame-Options \"SAMEORIGIN\"\n&lt;\/IfModule&gt;<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">This example adds three commonly used headers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Important\"><\/span>Important<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Do not blindly copy large collections of security headers from random tutorials.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Every website has different requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An incorrect header configuration can break legitimate functionality.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Adding_HSTS_With_htaccess\"><\/span>Adding HSTS With <code>.htaccess<\/code><span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Once HTTPS is fully configured and working correctly, an HSTS header can be added.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>&lt;IfModule mod_headers.c&gt;\n    Header always set Strict-Transport-Security \"max-age=31536000\"\n&lt;\/IfModule&gt;<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Before enabling HSTS, make sure:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>HTTPS works correctly.<\/li>\n\n\n\n<li>HTTP redirects properly to HTTPS.<\/li>\n\n\n\n<li>Important subdomains support HTTPS if they will be

class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">If your WordPress website uses Nginx, headers can be configured in the server configuration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>add_header X-Content-Type-Options \"nosniff\" always;\nadd_header Referrer-Policy \"strict-origin-when-cross-origin\" always;\nadd_header X-Frame-Options \"SAMEORIGIN\" always;<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">HSTS could be configured after HTTPS is confirmed:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>add_header Strict-Transport-Security \"max-age=31536000\" always;<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">The exact configuration location depends on your Nginx setup.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After changing Nginx configuration, validate the configuration before reloading the server.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Method_3_Add_Security_Headers_Through_a_WordPress_Plugin\"><\/span>Method 3: Add Security Headers Through a WordPress Plugin<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">If you do not have server-level access, a WordPress security or header-management plugin may provide an easier interface.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The general process is:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Install a reputable plugin.<\/li>\n\n\n\n<li>Activate it.<\/li>\n\n\n\n<li>Locate its security header settings.<\/li>\n\n\n\n<li>Select the headers you want.<\/li>\n\n\n\n<li>Configure the values.<\/li>\n\n\n\n<li>Save the settings.<\/li>\n\n\n\n<li>Test the website.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">A plugin can be convenient for administrators who are not comfortable editing Apache or Nginx configuration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, avoid installing several plugins that all attempt to modify the same headers.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Method_4_Add_Security_Headers_Through_Cloudflare\"><\/span>Method 4: Add Security Headers Through Cloudflare<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">If your website uses Cloudflare or another reverse proxy\/CDN, security headers can also be configured at the edge.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This can allow headers to be added before responses reach visitors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The exact configuration depends on the Cloudflare features and plan available to your account.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before adding headers at the CDN level, check whether your WordPress hosting or security plugin already adds them.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Otherwise, you may create duplicate or conflicting headers.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Recommended_Starting_Configuration\"><\/span>Recommended Starting Configuration<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">For many WordPress websites, it is reasonable to start with a small set of relatively straightforward headers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>X-Content-Type-Options: nosniff\nReferrer-Policy: strict-origin-when-cross-origin\nX-Frame-Options: SAMEORIGIN<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Then consider HSTS after HTTPS has been thoroughly tested.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">CSP and advanced cross-origin policies should generally be introduced more carefully because they can have a greater effect on website functionality.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Add_a_Content_Security_Policy\"><\/span>How to Add a Content Security Policy<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">CSP is one of the most powerful security headers, but it is also one of the easiest to configure incorrectly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A simple policy might look like:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>Content-Security-Policy: default-src 'self'<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">However, this may break many WordPress websites.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A real WordPress website may load resources

Commonly considered headers include HSTS, CSP, <code>X-Content-Type-Options<\/code>, <code>Referrer-Policy<\/code>, <code>X-Frame-Options<\/code>, and <code>Permissions-Policy<\/code>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The correct configuration depends on your website&#8217;s functionality.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Can_security_headers_break_my_WordPress_website\"><\/span>Can security headers break my WordPress website?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Yes.

Headers such as <strong>HSTS, Content-Security-Policy, X-Content-Type-Options, Referrer-Policy, X-Frame-Options, and Permissions-Policy<\/strong> can provide additional controls over how browsers interact with your website.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, security headers work best as part of a broader security strategy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Keep WordPress and its plugins updated, use strong authentication, protect administrator accounts, scan for malware, maintain reliable backups, use secure hosting, and monitor suspicious activity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Most importantly, <strong>do not copy a complex security-header configuration without testing it<\/strong>. Start with simpler policies, understand your website&#8217;s dependencies, introduce stricter controls gradually, and verify the final HTTP response.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A carefully tested security-header configuration can strengthen WordPress without sacrificing the functionality your visitors and administrators rely on.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"How to Add Security Headers to WordPress WordPress security is not limited to strong passwords, plugins, firewalls, and&hellip;","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"csco_display_header_overlay":false,"csco_singular_sidebar":"","csco_page_header_type":"","footnotes":""},"categories":[134],"tags":[],"class_list":["post-2614","post","type-post","status-publish","format-standard","category-wordpress-web-hosting","cs-entry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>How to Add Security Headers to WordPress?
