| 1. General Results, most used to calculate the result |
| A | name "test-mediamaps.em-sourcing.com" is subdomain, public suffix is ".com", top-level-domain is ".com", top-level-domain-type is "generic", tld-manager is "VeriSign Global Registry Services", num .com-domains preloaded: 108094 (complete: 276475)
|
| A | Good: All ip addresses are public addresses
|
| Warning: Only one ip address found: test-mediamaps.em-sourcing.com has only one ip address.
|
| Warning: No ipv6 address found. Ipv6 is the future with a lot of new features. So every domain name should have an ipv6 address. See https://en.wikipedia.org/wiki/IPv6: test-mediamaps.em-sourcing.com has no ipv6 address.
|
| A | Good: No asked Authoritative Name Server had a timeout
|
| A | DNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
|
| A | Good: destination is https
|
| A | Good - only one version with Http-Status 200
|
| A | Good: one preferred version: non-www is preferred
|
| A | Good: every cookie sent via https is marked as secure
|
| A | Good: Every cookie has a SameSite Attribute with a correct value Strict/Lax/None
|
| HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
|
| A | Good: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)
|
| I | https://test-mediamaps.em-sourcing.com/ 212.144.229.52
|
| Content problems or problems with resources included - http links, files doesn't exist, different Content-Type definitions. Check the Html-Content - Part.
|
| O |
|
| X | Fatal error: Nameserver doesn't support TCP connection: ns2.antagus.de / 195.191.93.10: Timeout
|
| Info: Checking the ip addresses of that domain name not exact one certificate found. So it's impossible to check if that domain requires Server Name Indication (SNI).: Domain test-mediamaps.em-sourcing.com, 1 ip addresses.
|
| B | No _mta-sts TXT record found (mta-sts: Mail Transfer Agent Strict Transport Security - see RFC 8461). Read the result of server-daten.de (Url-Checks, Comments, Connections and DomainServiceRecords) to see a complete definition. Domainname: _mta-sts.test-mediamaps.em-sourcing.com
|
| 2. Header-Checks |
| A | test-mediamaps.em-sourcing.com 212.144.229.52
| Content-Security-Policy
| Ok: Header without syntax errors found: default-src 'self'; font-src 'self'; img-src 'self' data: https://maps.omniscale.net; media-src 'self'; form-action 'self' https://test-ems.smart-media.world https://test-sug.smart-media.world; object-src 'self'; script-src 'unsafe-eval' 'unsafe-inline' 'self'; worker-src 'self' blob:; child-src 'self' blob:; style-src 'self' 'unsafe-inline'; manifest-src 'none'; connect-src 'self' https://test-ems.smart-media.world https://test-sug.smart-media.world; frame-src https://test-ems.smart-media.world https://test-sug.smart-media.world blob: 'self'; frame-ancestors https://test-ems.smart-media.world https://test-sug.smart-media.world
|
| A |
|
| Good: default-src directive only with 'none' or 'self', additional sources are blocked. font-src, media-src, object-src
|
| A |
|
| Good: default-src without 'unsafe-inline' or 'unsave-eval'. font-src, media-src, object-src
|
| A |
|
| Good: form-action directive found. That reduces the risk sending data to unwanted domains. form-action is a navigation-directive, so default-src isn't used.
|
| A |
|
| Good: frame-ancestors directive found. That limits pages who are allowed to use this page in a frame / iframe / object / embed / applet. frame-ancestors is a navigation-directive, so default-src isn't used.
|
| E |
|
| Bad: No base-uri directive found. Use one to limit the URLs which can be used in a document's <base> element. Because it's a document directive, default-src isn't used, so an own directive is required.
|
| A |
|
| Good: object-src only with 'none' or 'self' found, no scheme, no other urls. That blocks object / embed / applet - elements.
|
| F |
|
| Critical: script-src with 'unsafe-inline' or 'unsafe-eval' and without a nonce found. That's dangerous, don't use it. If you really need one of these unsafe directives, add a nonce.
|
| A |
|
| Good: script-src without * and a scheme found.
|
| A |
|
| Good: script-src without data: schema found. Why is this important? The data: schema allows hidden code injection. Insert <script src='data:application/javascript;base64,YWxlcnQoJ1hTUycpOw=='></script> in your page and see what happens.
|
| A |
|
| Good: frame-src without data: defined or frame-src missing and the default-src used as fallback not allows the data: schema. That blocks hidden code injection. Insert <iframe src="data:text/html;charset=utf-8;base64,PCFET0NUWVBFIGh0bWw+PGh0bWw+PGJvZHk+PHA+YmVmb3JlPHNjcmlwdCB0eXBlPSJ0ZXh0L2phdmFzY3JpcHQiPmFsZXJ0KCdYU1MnKTwvc2NyaXB0PjxwPmFmdGVyPC9ib2R5PjwvaHRtbD4="></iframe> in your page and see what happens.
|
| C |
|
| Info: default-src and some other fetch directives have the same list of values. Remove the other fetch directive, default-src is used as fallback. Directives to remove: font-src, media-src, object-src
|
| A |
| X-Content-Type-Options
| Ok: Header without syntax errors found: nosniff
|
| A |
| Referrer-Policy
| Ok: Header without syntax errors found: strict-origin-when-cross-origin
|
| A |
| X-Xss-Protection

| 3. DNS- and NameServer - Checks |
| A | Info:: 2 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 2 Name Servers.
|
| A | Info:: 2 Queries complete, 2 with IPv6, 0 with IPv4.
|
| A | Good: All DNS Queries done via IPv6.
|
| A | Good: Some ip addresses of name servers found with the minimum of two DNS Queries. One to find the TLD-Zone, one to ask the TLD-Zone.ns1.antagus.de (195.191.92.10, 2001:67c:2394:1::1001), ns2.antagus.de (195.191.93.10, 2001:67c:2394:3::1001)
|
| A | Good (1 - 3.0):: An average of 1.0 queries per domain name server required to find all ip addresses of all name servers.
|
| A | Info:: 2 different Name Servers found: ns1.antagus.de, ns2.antagus.de, 2 Name Servers included in Delegation: ns1.antagus.de, ns2.antagus.de, 2 Name Servers included in 1 Zone definitions: ns1.antagus.de, ns2.antagus.de, 1 Name Servers listed in SOA.Primary: ns1.antagus.de.
|
| A | Good: Only one SOA.Primary Name Server found.: ns1.antagus.de.
|
| A | Good: SOA.Primary Name Server included in the delegation set.: ns1.antagus.de.
|
| A | Good: Consistency between delegation and zone. The set of NS records served by the authoritative name servers must match those proposed for the delegation in the parent zone. Ordered list of name servers: ns1.antagus.de, ns2.antagus.de
|
| A | Good: All Name Server Domain Names have a Public Suffix.
|
| A | Good: All Name Server Domain Names ending with a Public Suffix have minimal one IPv4- or IPv6 address.
|
| A | Good: All Name Server ip addresses are public.
|
| A | Good: Minimal 2 different name servers (public suffix and public ip address) found: 2 different Name Servers found
|
| A | Good: All name servers have ipv4- and ipv6-addresses.: 2 different Name Servers found
|
| Warning: All Name Servers have the same Top Level Domain / Public Suffix. If there is a problem with that Top Level Domain, your domain may be affected. Better: Use Name Servers with different top level domains.: 2 Name Servers, 1 Top Level Domain: de
|
| Warning: All Name Servers have the same domain name. If there is a problem with that domain name (or with the name servers of that domain name), your domain may be affected. Better: Use Name Servers with different domain names / different top level domains.: Only one domain name used: antagus.de
|
| Warning: All Name Servers from the same Country / IP location.: 2 Name Servers, 1 Countries: DE
|
| A | Info: Ipv4-Subnet-list: 2 Name Servers, 1 different subnets (first Byte): 195., 1 different subnets (first two Bytes): 195.191., 2 different subnets (first three Bytes): 195.191.92., 195.191.93.
|
| A | Good: Name Server IPv4-addresses from different subnet found:
|
| A | Info: IPv6-Subnet-list: 2 Name Servers with IPv6, 1 different subnets (first block): 2001:, 1 different subnets (first two blocks): 2001:067c:, 1 different subnets (first three blocks): 2001:067c:2394:, 2 different subnets (first four blocks): 2001:067c:2394:0001:, 2001:067c:2394:0003:
|
| A | Good: Name Server IPv6 addresses from different subnets found.
|
| A | Good: Nameserver supports TCP connections: 2 good Nameserver
|
| A | Good: Nameserver supports Echo Capitalization: 2 good Nameserver
|
| A | Good: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 2 good Nameserver
|
| A | Good: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 2 good Nameserver
|
| Nameserver doesn't pass all EDNS-Checks: ns1.antagus.de: OP100: no result. FLAGS: no result. V1: no result. V1OP100: no result. V1FLAGS: no result. DNSSEC: no result. V1DNSSEC: no result. NSID: no result. COOKIE: no result. CLIENTSUBNET: no result.
|
| Nameserver doesn't pass all EDNS-Checks: ns2.antagus.de / 195.191.93.10: OP100: ok. FLAGS: ok. V1: SOA NOT expected, but found, BADVER expected, NOERR found, Version 0 expectend and found. V1OP100: SOA NOT expected, but found, BADVER expected, NOERR found, Version 0 expectend and found, no OPT100 expected, no OPT100 found.

V1DNSSEC: SOA NOT expected, but found, BADVER expected, NOERR found, Version 0 expectend and found. NSID: ok. COOKIE: ok. CLIENTSUBNET: ok.
|
| A | Good: All SOA have the same Serial Number
|
| Warning: No CAA entry with issue/issuewild found, every CAA can create a certificate. Read https://en.wikipedia.org/wiki/DNS_Certification_Authority_Authorization to learn some basics about the idea of CAA. Your name server must support such an entry. Not all dns providers support CAA entries.
|
| 4. Content- and Performance-critical Checks |
| http://test-mediamaps.em-sourcing.com/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 212.144.229.52
|
| Fatal: Check of /.well-known/acme-challenge/random-filename has a timeout. Creating a Letsencrypt certificate via http-01 challenge can't work. You need a running webserver (http) and an open port 80. If it's a home server + ipv4, perhaps a correct port forwarding port 80 extern ⇒ working port intern is required. Port 80 / http can redirect to another domain port 80 or port 443, but not other ports. If it's a home server, perhaps your ISP blocks port 80. Then you may use the dns-01 challenge. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
|
| A | Good: Every https result with status 200 and greater 1024 Bytes is compressed (gzip, deflate, br checked).
|
| https://test-mediamaps.em-sourcing.com/ 212.144.229.52
|
| Warning: Https + http status 200 + Inline CSS / JavaScript found. Don't use inline CSS / JavaScript. These are compiled and re-used ressources, save these with a long Cache-Control max-age - header.
|
| https://test-mediamaps.em-sourcing.com/ 212.144.229.52
|
| Warning: Https result with status 200 found, Html-Content is too big. Should be max. 110 %. May contain inline CSS / JavaScript, too much comments or white space. Re-used ressources - create files with a long Cache-Control max-age header. Remove comments and white space.
|
| A | Good: Every https connection via port 443 supports the http/2 protocol via ALPN.
|
| https://test-mediamaps.em-sourcing.com/ 212.144.229.52
|
| Critical: Some script Elements (type text/javascript) with a src-Attribute don't have a defer / async - Attribute. Loading and executing these JavaScripts blocks parsing and rendering the Html-Output. That's bad if your site is large or the connection is slow / mobile usage. Use "async" if the js file has only functions (so nothing is executed after parsing the file) or is independend. Use "defer" if the order of the scripts is important. All "defer" scripts are executed before the DOMContentLoaded event is fired. Check https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script to see some details.: 1 script elements without defer/async.
|
| Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 2 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 0 with Cache-Control max-age too short (minimum 7 days), 0 with Cache-Control long enough, 2 complete.
|
| A | Good: All checked attribute values are enclosed in quotation marks (" or ').
|
| A | Info: No img element found, no alt attribute checked
|
| A | Good: Domainname is not on the "Specially Designated Nationals And Blocked Persons List" (SDN). That's an US-list of individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries. It also lists individuals, groups, and entities, such as terrorists and narcotics traffickers designated under programs that are not country-specific. Collectively, such individuals and companies are called "Specially Designated Nationals" or "SDNs." Their assets are blocked and U.S. persons are generally prohibited from dealing with them. So if a domain name is on that list, it's impossible to create a Letsencrypt certificate with that domain name. Check the list manual - https://www.treasury.gov/resource-center/sanctions/sdn-list/pages/default.aspx
