Why HSTS is Important

HTTP Strict Transport Security (HSTS) is a web security policy that forces browsers to use only HTTPS connections to a website. This helps to prevent man-in-the-middle attacks, which can eavesdrop on or hijack unencrypted HTTP traffic. HSTS is essential for protecting sensitive data, such as login credentials and financial information.

How to Check if HSTS is Missing

You can check if HSTS is missing from your HTTPS server by using a tool like Qualys SSL Labs. Simply enter your website's URL and click "Submit". The results will show you whether or not HSTS is enabled.

How to Enable HSTS

If HSTS is missing from your HTTPS server, you can enable it by adding the following header to your web server's configuration file: Strict-Transport-Security: max-age=31536000; includeSubdomains; preload This header will tell browsers to use only HTTPS connections to your website for the next year. You can also choose to include subdomains and preload your website in the HSTS preload list, which will help to protect your website from even more attacks.

Conclusion

HSTS is a critical web security policy that helps to protect your website from man-in-the-middle attacks. If HSTS is missing from your HTTPS server, you should enable it immediately. By following the steps outlined in this blog post, you can help to keep your website and your users' data safe.
