Problems

  • ✗
    Zone transfer allowed
    Nameservers · These nameservers send the complete zone to anyone who asks (AXFR), exposing all host names: rsm.enst-bretagne.fr (192.44.77.1): 602 records. Restrict zone transfers to your secondary servers.
    #18
  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: rsm.enst-bretagne.fr. matell.enst-bretagne.fr, ns2.nic.fr, rsm.enst-bretagne.fr, univers.enst-bretagne.fr report NS matell.enst-bretagne.fr ns2.nic.fr rsm.enst-bretagne.fr univers.enst-bretagne.fr.
    #7
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: matell.enst-bretagne.fr: "0.0.0-REL"; rsm.enst-bretagne.fr: "9.4.2-P2"; univers.enst-bretagne.fr: "0.0.0-REL". Hide or replace the version string.
    #17
  • !
    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

  • ✗
    Policy: none (monitoring only)
    DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.
    #4
  • !
    No key under common selectors
    DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.
    #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: legacy-dom.imt-atlantique.fr
    #11
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    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.
