Critical gaps in: DMARC / Email Security. Positive signals: MX Records & Mail Provider, DNS CAA Records, TLS Configuration all passed.

1 action item identified, including 1 critical. The issues are configuration gaps, not architectural problems. A focused remediation effort of 2–5 days could address all findings.

Security checks

Each check inspects a different part of iana.org's public security setup. Green means healthy, yellow needs attention, red is a problem.

DMARC / Email Security
Strengths: SPF record present. Issues: DMARC policy is 'none' (monitoring only, no enforcement); No DKIM records found for common selectors (domain may use custom selectors — this is not a confirmed gap).
Problem
MTA-STS & TLS Reporting
Issues: No MTA-STS configured — email in transit is vulnerable to TLS downgrade attacks. Sending servers cannot verify that your mail server requires TLS; No TLSRPT record — TLS delivery failures won't be reported to domain owner.
Needs work
MX Records & Mail Provider
Strengths: Mail handled by pechora6.icann.org; 4 MX record(s) configured; Multiple MX records provide redundancy; All MX records share the same priority (10) — round-robin load balancing (no primary/backup distinction).
Healthy
DNS CAA Records
Strengths: CAA records configured (7 record(s)); Authorized CAs: sectigo.com, digicert.com, letsencrypt.org, pki.goog; Violation reporting (iodef) configured.
Healthy
TLS Configuration
TLSv1.3 negotiated with TLS_AES_256_GCM_SHA384 (256-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
Healthy
DNS Configuration
Strengths: 4 nameservers configured (ns.icann.org., a.iana-servers.net., c.iana-servers.net., b.iana-servers.net.); 4 MX records present; DNSSEC enabled; Zone transfers properly restricted.
Healthy
TLS Protocol Support
Strengths: TLS 1.3 supported; TLS 1.2 supported; TLS 1.3 supported (strongest). Protocol support: TLS 1.3: Yes, TLS 1.2: Yes, TLS 1.1: No, TLS 1.0: No.
Healthy
Known Breaches
No known breaches found in public disclosure databases.
Healthy
Cookie Security
No cookies set on the homepage response. No cookie security flags to evaluate.
Healthy
HSTS Header
HSTS enabled: max-age=48211200s (558 days). Missing includeSubDomains — subdomains not covered. preload present.
Healthy
Security Headers
4/5 security headers present. Missing: Permissions-Policy.
Healthy
security.txt (RFC 9116)
Strengths: security.txt found with 6 field(s); Contact: https://hackerone.com/icann, mailto:[email protected]; Encryption key provided for secure reporting; Disclosure policy: https://www.icann.org/vulnerabilities; Canonical URL specified; Preferred languages: en, es, fr, ar, ru, zh. Issues: Missing 'Expires' field (required by RFC 9116); Not PGP signed (recommended for authenticity).
Healthy
CVE Exposure
Detected technologies: Apache. No version information exposed — CVE matching not possible (this is good practice).
Healthy
Certificate Hygiene
Strengths: Certificate valid, 274 days remaining; Issued by Sectigo Limited. Note: Wildcard certificate in use (*.domain) — covers all subdomains. Common practice; worth noting that compromise would affect all subdomains.
Healthy
Recommended actions

Steps to improve iana.org's security grade, ranked by impact.

1
Set up email authentication (DKIM)
Impact: 1–2 Days
CRITICAL
Without email authentication, anyone can send emails that appear to come from iana.org. This is the most common vector for phishing attacks targeting employees and customers. DKIM is not configured.
Compliance impact
NIST CSFPR.AC-7
Email authentication is a required access control
ISO 27001A.13.2.1
Information transfer policies require email security controls
HIPAA§164.312(e)
Transmission security for electronic PHI
How to fix this
1
Add SPF record to DNS: v=spf1 include:_spf.google.com ~all (adjust for your email provider)
2
Configure DKIM signing with your email provider and publish the public key in DNS
3
Add DMARC record: v=DMARC1; p=quarantine; rua=mailto:[email protected]
4
Monitor DMARC reports for 2–4 weeks, then upgrade policy to p=reject
