HTTP status: 5 Sub-resource URL
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 0
.
X-Frame-Options: SAMEORIGIN
Clickjacking protection is enabled
+2
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
).
X-Content-Type-Options: nosniff
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.

P3P is a mostly abandoned standard for website privacy policy declaration that has little use today. Please consider switching to DoNotTrack standard.
0
Largely abandoned format for declaring website's privacy policy in machine-readable format. The only reason for many websites to use the header was that old versions of Microsoft Internet Explorer disallowed third-party cookies on websites missing P3P.
