Problems

  • ✗
    Zone transfer allowed
    Nameservers · These nameservers send the complete zone to anyone who asks (AXFR), exposing all host names: imisunf01.med.uni-giessen.de (141.50.161.11): 38 records; imisunf03.med.uni-giessen.de (141.50.161.12): 38 records. Restrict zone transfers to your secondary servers.
    #18
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: imisunf01.med.uni-giessen.de: "9.9.5-3ubuntu0.1-Ubuntu"; imisunf03.med.uni-giessen.de: "9.9.5-3ubuntu0.1-Ubuntu". Hide or replace the version string.

  • !
    Unusual SOA timers
    SOA · negative caching TTL (minimum) 2d is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 6h, retry 30m, expire 7d, negative TTL 2d.
    #23
  • !
    Not signed
    DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.

Problems

  • ✗
    No DMARC record
    DMARC · No DMARC record was found for this domain. DMARC is essential for preventing email spoofing. Add a DMARC record with p=reject or at least p=quarantine.
    #5
  • ✗
    No DKIM keys published
    DKIM · _domainkey.ukgm.de does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.
    #7
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mail.uk-gm.de, mail2.uk-gm.de
    #11
  • !
    Not configured
    TLS · MTA-STS is not configured, so other mail servers fall back to unencrypted delivery when TLS fails or is stripped by an attacker. Publish a _mta-sts TXT record and a policy at https://mta-sts.<domain>/.well-known/mta-sts.txt.
