|
| 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: default-src directive only with 'none' or 'self', additional sources are blocked.
|
| A |
|
| Good: default-src without 'unsafe-inline' or 'unsave-eval'.
|
| 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.
|
| A |
|
| Good: base-uri directive found. That limits 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: No object-src found, but the default-src used as fallback is defined and restricted.
|
| A |
|
| Good: script-src without 'unsafe-inline' and 'unsafe-eval' found. That's the recommended configuration.
|
| F |
|
| Critical: script-src with * or a scheme found. Never allow wildcard - sources.
|
| 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.

|
| 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.glddns.com (44.235.104.247), ns2.glddns.com (44.235.104.247)
|
| 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.glddns.com, ns2.glddns.com, 2 Name Servers included in Delegation: ns1.glddns.com, ns2.glddns.com, 2 Name Servers included in 1 Zone definitions: ns1.glddns.com, ns2.glddns.com, 1 Name Servers listed in SOA.Primary: ns1.glddns.com.
|
| A | Good: Only one SOA.Primary Name Server found.: ns1.glddns.com.
|
| A | Good: SOA.Primary Name Server included in the delegation set.: ns1.glddns.com.
|
| 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.glddns.com, ns2.glddns.com
|
| 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
|
| Warning: No Name Server IPv6 address found. IPv6 is the future, so your name servers should be visible via IPv6.: 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: com
|
| 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: glddns.com
|
| Warning: All Name Servers from the same Country / IP location.: 2 Name Servers, 1 Countries: US
|
| A | Info: Ipv4-Subnet-list: 2 Name Servers, 1 different subnets (first Byte): 44., 1 different subnets (first two Bytes): 44.235., 1 different subnets (first three Bytes): 44.235.104.
|
| X | Fatal: All Name Server IPv4 addresses from the same subnet. Check https://www.iana.org/help/nameserver-requirements to learn some basics about name server configurations. If you manage these name servers, fix it. If it's your provider, change your provider.:
|
| X | Fatal: Only one Name Server IPv4 address found. Check https://www.iana.org/help/nameserver-requirements to learn some basics about name server configurations. If you manage these name servers, fix it. If it's your provider, change your provider.
|
| A | Good: Nameserver supports TCP connections: 1 good Nameserver
|
| A | Good: Nameserver supports Echo Capitalization: 1 good Nameserver
|
| A | Good: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 1 good Nameserver
|
| A | Good: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 1 good Nameserver
|
| Nameserver doesn't pass all EDNS-Checks: ns1.glddns.com: 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.
|
| 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 |
| https://aqc4642.glddns.com/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de
|
| Fatal: Check of /.well-known/acme-challenge/random-filename has a http status 500 - 599, Server Error. Creating a Letsencrypt certificate via http-01 challenge can't work. 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://aqc4642.glddns.com/index.php/login
|
| 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://aqc4642.glddns.com/index.php/login
|
| 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.
|
| https://aqc4642.glddns.com/index.php/login
|
| Warning: Https connections (Standard Port 443) found without support of the http/2 protocol via ALPN. Http/2 is the new Http-Version (old: http 1.1) with some important new features. Update your server software so http/2 is available. Only one TCP-connection per Server (that's a performance boost), Header-Compression and Server Pushs are available. Domain Sharding and Inline-CSS/Javascript shouldn't used with http/2.
|
| A | Good: All script Elements (type text/javascript) and src-Attribute have a defer / async - Attribute. So loading and executing these JavaScripts doesn't block parsing and rendering the Html-Output.
|
| Warning: CSS / JavaScript found without Compression. Compress these ressources, gzip, deflate, br are checked. 19 external CSS / JavaScript files without Compression found - 0 with Compression, 19 complete
|
| Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 0 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 10 with Cache-Control max-age too short (minimum 7 days), 12 with Cache-Control long enough, 22 complete.
|
| A | Good: All checked attribute values are enclosed in quotation marks (" or ').
|
| A | Good: Some img-elements have a valid alt-attribute.: 2 img-elements found, 1 img-elements with correct alt-attributes (defined, not an empty value).
|
| Wrong: img-elements without alt-attribute or empty alt-attribute found. The alt-attribute ("alternative") is required and should describe the img. So Screenreader and search engines are able to use these informations.: 1 img-elements without alt-attribute, 0 img-elements with empty alt-attribute found.
|
| 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
