Why it's important
The X-Content-Type-Options header helps prevent browsers from interpreting files as a different MIME type than what is specified. This is a security measure that prevents certain types of attacks, such as MIME sniffing. Without this header, there is a risk that malicious content might be executed if a browser misinterprets the type of content being served.User stories
