Website Security

Bertelsmann

X-Frame-Options is not deny or sameorigin

Browsers may display this website's content in frames. This can lead to clickjacking attacks.

CSP is not implemented

No valid Content Security Policy is implemented. This increases the risk of XSS and clickjacking attacks.

X-Content-Type-Options is not nosniff

Browsers may interpret files as a different MIME type than what is specified in the Content-Type HTTP header. This can lead to MIME confusion attacks.

Server information header not exposed

Ensuring the server information header is not exposed reduces the ability of attackers to exploit certain vulnerabilities.

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.

Email

Bertelsmann

DMARC policy is p=none

DMARC policy is p=none. This provides no protection against fraudulent emails. The DMARC policy should be migrated to p=quarantine, and eventually p=reject.

SPF policy uses ~all

Sender Policy Framework (SPF) record is too lenient as to which domains are allowed to send email on the domain's behalf. This record should preferably not use the ~all mechanism, as this does not instruct the mail receiver to reject messages from unauthorised sources. When DMARC is not being enforced, -all should be used on the SPF record.

DMARC policy exists

DMARC protects against fraudulent emails being sent from a domain.

SPF enabled

Sender Policy Framework (SPF) records prevent spammers from sending messages with forged addresses.

SPF syntax correct

Sender Policy Framework (SPF) record passes basic syntax checks.

SPF ptr mechanism not used

Sender Policy Framework (SPF) record does not include the ptr mechanism.
