Security-related HTTP headers

  • X-Content-Type-Options: nosniff

    A non-standard but widely accepted header introduced originally by Microsoft to disable "content sniffing" or heuristic content type discovery in absence or mismatch of a proper HTTP Content-Type declaration, which led to a number of web attacks. In general, presence of the header with its only defined value of nosniff is considered as part of a properly secured HTTP response.


  • Strict-Transport-Security: max-age=31536000; includeSubdomains; preload

    HTTP Strict Transport Security (HSTS) is an opt-in security enhancement that is specified by a web application through the use of a special response header.


  • Content-Security-Policy: default-src 'self'; img-src 'self' blob: data:; style-src 'self' 'unsafe-inline'; script-src 'self'; font-src 'self' data:; frame-src 'self'; connect-src 'self'; media-src 'self' data: blob:; report-uri

    Content Security Policy is used by a web server to declare a list of trusted content types (images, scripts, media etc) and origins from which they can be safely loaded as intended by the website authors. The Content-Security-Policy-Report-Only header instruct the browser to enable CSP in enforcement mode.


  • X-Frame-Options: DENY

    Instructs the browser if the current website can be embedded in HTML frame by another website. Since this allows the parent website to control the framed page, this creates a potential for data theft attacks ("clickjacking") and most sensitive websites won't allow them to be framed at all (deny) or just allow parts of them to be embedded in frames created by themselves only (samesite).


  • Server: Google Frontend

    Announces web server software and optionally version details.


  • X-XSS-Protection: 1; mode=block

    Controls an Cross-Site Scripting (XSS) filters built into the majority of web browsers. The filter is usually turned on by default anyway, but requirement to set the header to 1 became part of canonical set of "secure" HTTP headers. Over time, vulnerabilities in the "sanitizing" mode filter were found, so 1; mode=block became the recommended value. Some companies decided that they don't really need a browser-side XSS filter to mess with their web services which are XSS-free anyway and they became consciously disabling the XSS filter by setting the header to 0.
