HTTPS & TLS

100/100A⁺

HTTPS certificateAmazon10/10
HTTPS with a valid certificate from Amazon.
Certificate expiry1584/4
The certificate is valid for another 158 days.
TLS versionTLS 1.34/4
Negotiates TLS 1.3, the current protocol: faster handshakes, forward secrecy always.
Old protocols3/3
Refuses the retired TLS 1.0 and 1.1.
Key strengthRSA 20482/2
A strong key: RSA 2048.
HTTP → HTTPS3023/3
http:// redirects straight to https://.
HSTS1 year4/4
HSTS tells browsers to use HTTPS only, for 1 year.
HTTP/2 and HTTP/3HTTP/22/2
HTTP/2.

DNS

43/100F

Name servers answer2/32/5
2 of 3 name servers answer for the domain; the others leave resolvers waiting.
DNSSEC0/3
Not signed with DNSSEC: a forged DNS answer for the domain cannot be told from the real one.
CAA records0/2
No CAA records: any certificate authority may issue certificates for the domain.
Name servers34/4
3 name servers for the domain.

Email

73/100C

MTA-STS0/2
No MTA-STS: mail to the domain can be read in transit by stripping its encryption.
TLS reporting0/0.5
No TLS reporting: failed encrypted deliveries go unnoticed.
SPF-all5/5
SPF lists the servers allowed to send its mail and rejects the rest (-all).
DMARCquarantine5/7
DMARC sends mail that fakes the domain to spam (p=quarantine).
DKIMgoogle2/2
A DKIM key is published (selector google), so its mail can be signed.

Web & network

88/100A

Content Security Policypartial1.5/3
A Content Security Policy is sent, but it does not limit scripts.
Permissions-Policy0/0.5
No Permissions-Policy: embedded content may ask for camera, microphone or location.
X-Content-Type-Options2/2
X-Content-Type-Options: nosniff stops browsers guessing file types.
Framing2/2
Other sites cannot frame its pages (clickjacking protection).
Referrer-Policystrict-origin-when-cross-origin0.5/0.5
Referrer-Policy limits what other sites learn about where visitors came from.
IPv64/4
www.un.org is reachable over IPv6 as well as IPv4.
RPKIvalid4/4
The route to the website is RPKI-valid: networks can reject hijacked announcements of it.

Dependencies

DNS providersSelf-hosted5/5
DNS is served from 2 separate networks.
One company for everything5/5
The website, DNS and email do not all hang on one company.

What is graded

HTTPS & TLS · 25%

A valid certificate (an invalid one means F), its expiry against its lifetime, TLS 1.3, no TLS 1.0/1.1 (else at most B), http:// sent straight to https://, HSTS, HTTP/2.

DNS · 20%

At least two name servers that all answer and agree, DNSSEC, CAA records, and a registration that is not about to expire.

Email · 20%

SPF, a DMARC policy that rejects forgeries (none means at most B), MTA-STS and TLS reporting for domains that take mail, DKIM at common selectors.

Web & network · 20%

Content Security Policy, nosniff, framing protection, Referrer- and Permissions-Policy, IPv6, and an RPKI-valid route (invalid means at most C).

Dependencies · 15%

DNS from more than one provider, and the website, DNS and email not all with one company.
