Security checks — sorted by severity
DMARC / Email Security
Issues: No DMARC record found — email spoofing is not prevented; No SPF record found; No DKIM records found for common selectors (domain may use custom selectors — this is not a confirmed gap).

HSTS Header
Strict-Transport-Security header is missing. Connections can be downgraded to HTTP via man-in-the-middle attacks.

Security Headers
None of the 5 recommended security headers are present (missing: CSP, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy). This exposes the application to clickjacking, MIME-sniffing, and other client-side attacks.

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.

DNS CAA Records
No CAA records found. Without CAA, any Certificate Authority can issue certificates for this domain. Adding CAA records restricts issuance to authorized CAs only, reducing the risk of misissued certificates.

DNS Configuration
Strengths: DNSSEC enabled. Issues: No NS records found (unusual).

security.txt (RFC 9116)
No security.txt found. Publishing a security.txt at /.well-known/security.txt is the industry standard (RFC 9116) for vulnerability disclosure policies. Its absence may indicate a less mature security program.

MX Records & Mail Provider
No MX records found. This domain does not receive email directly — this is intentional for many domains and carries no security risk. If email is expected, verify mail routing via A/AAAA fallback or a mail provider.

Recommended actions
1+ items
Steps to improve arkrecode8.ero-labs.work's security grade, ranked by impact.
1
Set up email authentication (DMARC, SPF, DKIM)
Without email authentication, anyone can send emails that appear to come from arkrecode8.ero-labs.work. This is the most common vector for phishing attacks targeting employees and customers. DMARC, SPF, DKIM are not configured.
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
