Database engines should sit behind a private network.
What to do
Restrict 3306/tcp to a VPN, bastion, or allow-listed source range.

Database engines should sit behind a private network.
What to do
Restrict 5432/tcp to a VPN, bastion, or allow-listed source range.

SPF and DKIM alone do not protect the From: address a person sees. Without DMARC, a spoofed message can pass SPF for some other domain and still display yours.
What to do
Publish `_dmarc.mv-schloesser.de TXT "v=DMARC1; p=none; rua=mailto:dmarc@mv-schloesser.de"`, review the reports, then move to p=quarantine and p=reject.

FTP transmits credentials in cleartext.
What to do
Restrict 21/tcp to a VPN, bastion, or allow-listed source range.
asset: 78.46.125.13:21
Without HSTS the browser will still try http:// first on a fresh visit, which is the window an on-path attacker uses.
What to do
Send `Strict-Transport-Security: max-age=31536000; includeSubDomains` once you are sure everything works over HTTPS.

CSP is the main defence that limits what an injected script can do. Without it, any XSS bug is fully exploitable.
What to do
Start with a report-only policy, tighten it against the reports, then enforce.
asset: https://www.mv-schloesser.de/de/startseite/
No X-Frame-Options or CSP frame-ancestors directive, so another site can load this page invisibly inside its own and trick users into clicking.
What to do
Send `X-Frame-Options: DENY` or `Content-Security-Policy: frame-ancestors ’none’`.

78.46.125.13 (mv-schloesser.de) reports mariadb 10.11.18-MariaDB-0%2bdeb12u1. Publishing precise versions lets anyone match the host against a CVE feed without probing it, which is how targets get shortlisted for mass exploitation after a new advisory lands.
What to do
Suppress version tokens in server banners (for example `ServerTokens Prod` in Apache) and keep the packages current.
asset: 78.46.125.13
Lets browsers guess content types, which turns some upload and text endpoints into script injection points.
What to do
Send `X-Content-Type-Options: nosniff` on every response.
asset: https://www.mv-schloesser.de/de/startseite/
Full URLs — including any tokens or IDs in them — are sent to every third party the page links to.
What to do
Send `Referrer-Policy: strict-origin-when-cross-origin`.
asset: https://www.mv-schloesser.de/de/startseite/
Answers for this domain are not signed, so a resolver cannot tell a forged response from a real one.
What to do
Enable DNSSEC at your DNS host and publish the DS record at the registrar.
asset: mv-schloesser.de
Mail to this domain can be downgraded to plaintext by an on-path attacker, because senders have no way to know TLS is required.
What to do
Publish an MTA-STS policy (a TXT record plus a small HTTPS-hosted file).
asset: mv-schloesser.de
Any public certificate authority may issue certificates for this domain. CAA lets you name the ones allowed to.
What to do
Add a CAA record naming your CA, e.g. `0 issue "letsencrypt.org"`.
