Synopsis

Missing Content Security Policy

Description

Content Security Policy (CSP) is a web security standard that helps to mitigate attacks like cross-site scripting (XSS), clickjacking or mixed content issues. CSP provides mechanisms to websites to restrict content that browsers will be allowed to load.

No CSP header has been detected on this host. This URL is flagged as a specific example.

Solution

Configure Content Security Policy on your website by adding 'Content-Security-Policy' HTTP header or meta tag http-equiv='Content-Security-Policy'.
