Priority fixes for postermywall.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
Certificate lifetime of 100 days or less
Observed: The certificate from Amazon had a 197-day validity period, longer than the 100-day maximum that applies from March 2027.
Why it matters: Under CA/Browser Forum Ballot SC-081v3, the maximum lifetime of public TLS certificates fell to 200 days on 15 March 2026 and falls to 100 days on 15 March 2027 and 47 days on 15 March 2029. Sites that renew by hand will need to renew far more often.
What to do: Move to automated issuance and renewal now, while you still have time to test it.
72% of Design & Content Creation peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.
Priority 2 · Harden
security.txt published
Observed: No valid /.well-known/security.txt with a Contact field was returned.
What to do: Publish /.well-known/security.txt with at least Contact and Expires fields, as RFC 9116 requires, and review it before it expires.
9.1% of Design & Content Creation peers do this.
Priority 3 · Enable
Reachable over IPv6
Observed: No IPv6 (AAAA) address was published for www.postermywall.com.
What to do: Enable IPv6 at your CDN or host and publish the AAAA record it provides.
54% of Design & Content Creation peers do this.
Priority 4 · Harden
DNSSEC signed
Observed: No DS record was found for postermywall.com at its parent zone, so its DNS answers are not DNSSEC-signed.
What to do: Enable DNSSEC at your DNS provider, then add the DS record at your registrar. Plan provider moves carefully: a stale DS record can make the domain fail to resolve.
On Amazon Route 53: Enable DNSSEC signing for the hosted zone and establish the chain of trust at the registrar.
8.2% of Design & Content Creation peers do this.
