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
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 (
Clickjacking protection is enabled+2
XmlHttpRequest from a website that is not in the same origin, which is a precaution against various types of data stealing attacks. The target server has to explicitly allow the origin domain using the
Access-Control-Allow-Origin (ACAO) header, or it may allow all origins to access it using a wildcard
*. The latter however creates a potential security issue if the website in question is transactional and processing sensitive data, so the wildcard should be only used on websites consciously offering public APIs.
The header sets permissive AJAX access by using wildcard origin
*. It may be OK if the website is a publicly accessible REST API but otherwise it should be not present at all
Transport Layer Security (TLS) is enabled+2
