Expect-CT: max-age=604800, report-uri="https://report-uri.cloudflare.com/cdn-cgi/beacon/expect-ct"
The Expect-CT header allows sites to opt in to reporting and/or enforcement of Certificate Transparency requirements, which prevents the use of misissued certificates for that site from going unnoticed. When a site enables the Expect-CT header, they are requesting that the browser check that any certificate for that site appears in public CT logs.Read more...
X-XSS-Protection: 1; mode=block
XSS auditor is enabled in blocking mode+1
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
Header used by Adobe Flash engine to control cross-site access for Flash applications. Most websites not using Flash would prefer to set it with the value of
none as an additional precaution against using them in advanced Flash-based XSS vectors. Flash-serving websites can use them to declare the scope of detailed Flash cross-site policies per Adobe specification.
X-Frame-Options: “DENY”, SAMEORIGIN
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 (
Fuzzy content type guessing is disabled+1
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.
