Expect-CT: max-age=86400, report-uri="https://www.linkedin.com/platform-telemetry/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...
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.Read more...
HTTP Strict Transport Security is enabled+2
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.
Fuzzy content type guessing is disabled+1
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
