Nothing tells receiving mail servers which hosts may send as @doremus.org, so anyone can. Phishing that impersonates this domain will land in inboxes.
What to do
Publish an SPF TXT record listing your senders and ending in -all.
asset: doremus.org
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.doremus.org TXT "v=DMARC1; p=none; rua=mailto:dmarc@doremus.org"`, review the reports, then move to p=quarantine and p=reject.
asset: doremus.org
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.
asset: https://www.doremus.org/
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.doremus.org/
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’`.
asset: https://www.doremus.org/
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.doremus.org/
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.doremus.org/
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: doremus.org
Not urgent, but worth confirming auto-renew is on and the card on file is current.
What to do
Check auto-renew.
asset: doremus.org
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: doremus.org
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"`.
