Security headers direct and instruct web applications on how to handle your request and rely on responses from HTTP headers. It depends on the responses obtained from the metadata in the HTTP request to determine if the HTTP security header is not detected. Also, new browsers have a built-in protection system known as the XSS filter. However, it could be turned off by default, which leads to this problem. This isn’t the only error that you can encounter, and many reported HTTP 401 unauthorized error on their PC, but that can be easily fixed.

What causes the HTTP security header not to be detected?

Cross-site scripting (XXS) occurs when malicious and dangerous code is sent by the attacker to a different end-user. Hence, if your header lacks any of these during the attack, it could cause HTTP security header not detected.

X-frame options (Strict transport security): X-frame options help with improving the security of web applications against the threats and attacks from clickjacking. Clickjacking happens when an attacker uses different tricks to lure users into clicking on an unintended link. X-content type options: This reads or rather, allows the web application to sniff the MIMEtype to stop the browser from loading the styles and scripts from an incorrect MIMEtype. HTTP Strict Transport Security: This header deals with the browser’s built-in Cross-Site Scripting (XSS) filter, and prevents communication with illegitimate web servers.  It instructs your browser direct traffic to secure and legitimate HTTPS sites. X-XSS-Protection HTTP: This allows you to whitelist content sources. It can prevent all the XSS attacks and reduces the damage from those that get through.

Many reported HTTP security header not detected on port 80, and we’re going to show you how to fix that issue on several different platforms.
