Website Security

Canonical

Server information header exposed

Exposing information about the server version increases the ability of attackers to exploit certain vulnerabilities. The website configuration should be changed to prevent version information being revealed in the 'server' header.

X-Powered-By header not exposed

Information about specific technology used on the server is obscured.

Referrer policy is not unsafe-url

The website's Referrer Policy is not configured to allow unsafe information to be sent in the referrer header.

ASP.NET version header not exposing specific ASP.net version

Ensuring the ASP.NET version header is not exposing a specific version makes it harder for attackers to exploit certain vulnerabilities.

ASP.NET version header not exposed

Ensuring the ASP.NET version header is not exposed makes it harder for attackers to exploit certain vulnerabilities.
