|
| A | Good: More then one ip address per domain name found, checking all ip addresses the same http status and the same certificate found: Domain nyx.mynetblog.com, 2 ip addresses.
|
| Info: Checking all ip addresses of that domain without sending the hostname only one certificate found. Checking all ip addresses and sending the hostname only one certificate found. Both certificates are different. So that domain requires Server Name Indication (SNI), so the server is able to select the correct certificate.: Domain nyx.mynetblog.com, 2 ip addresses.

| A | nyx.mynetblog.com 92.38.149.105
| Content-Security-Policy
| Ok: Header without syntax errors found: frame-ancestors 'self';
|
| F |
|
| Bad: Missing default-src directive. A default-src directive is used if one of the specialized fetch directives (child-src, connect-src, font-src, frame-src, img-src, manifest-src, media-src, object-src, prefetch-src, script-src, style-src, worker-src) isn't defined. Missing default-src, all sources are allowed, that's bad. A default-src with 'none' or 'self' blocks that.
|
| E |
|
| Bad: No form-action directive found. Use one to limit the form - action - destinations. 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.
|
| F |
|
| Critical: No object-src and no default-src as fallback defined. So object / embed / applet can load every resource. That's fatal.
|
| F |
|
| Critical: No script-src and no default-src as fallback defined. So scripts are unlimited. That's fatal.

| Ok: Header without syntax errors found: sameorigin
|
| B |
|
| Info: Header is deprecated. May not longer work in modern browsers. sameorigin. Better solution: Use a Content-Security-Policy Header with a frame-ancestors directive. DENY - use 'none', SAMEORIGIN - use 'self'. If you want to allow some domains to frame your page, add these urls.

| 3. DNS- and NameServer - Checks |
| A | Info:: 2 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 3 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.dnsgcore.com (2a03:90c0:83:2907::e, 92.223.104.15), ns2.dnsgcore.com (2a03:90c0:c5::f, 92.223.66.22), ns3.dnsgcore.com (2a03:90c0:295::a, 45.135.229.16)
|
| A | Good (1 - 3.0):: An average of 0.7 queries per domain name server required to find all ip addresses of all name servers.
|
| A | Info:: 4 different Name Servers found: dnsmgr.gcorelabs.com, ns1.dnsgcore.com, ns2.dnsgcore.com, ns3.dnsgcore.com, 3 Name Servers included in Delegation: ns1.dnsgcore.com, ns2.dnsgcore.com, ns3.dnsgcore.com, 3 Name Servers included in 2 Zone definitions: ns1.dnsgcore.com, ns2.dnsgcore.com, ns3.dnsgcore.com, 1 Name Servers listed in SOA.Primary: dnsmgr.gcorelabs.com.
|
| A | Good: Only one SOA.Primary Name Server found.: dnsmgr.gcorelabs.com.
|
| Error: SOA.Primary Name Server not included in the delegation set.: dnsmgr.gcorelabs.com.
|
| A | Good: All Name Server Domain Names have a Public Suffix.
|
| Error: Name Server Domain Names with Public Suffix and without ip address found.: 1 Name Servers without ipv4 and ipv6: 1
|
|
|
| A | Info: Ipv4-Subnet-list: 3 Name Servers, 2 different subnets (first Byte): 45., 92., 2 different subnets (first two Bytes): 45.135., 92.223., 3 different subnets (first three Bytes): 45.135.229., 92.223.104., 92.223.66.

|
| A | Info: IPv6-Subnet-list: 3 Name Servers with IPv6, 1 different subnets (first block): 2a03:, 1 different subnets (first two blocks): 2a03:90c0:, 3 different subnets (first three blocks): 2a03:90c0:0083:, 2a03:90c0:00c5:, 2a03:90c0:0295:, 3 different subnets (first four blocks): 2a03:90c0:0083:2907:, 2a03:90c0:00c5:0000:, 2a03:90c0:0295:0000:
|
| A | Good: Name Server IPv6 addresses from different subnets found.
|
| A | Good: Nameserver supports TCP connections: 6 good Nameserver

|
| A | Good: All SOA have the same Serial Number
|
| A | Good: CAA entries found, creating certificate is limited: letsencrypt.org is allowed to create certificates
|
| 4. Content- and Performance-critical Checks |
| A | Good: All checks /.well-known/acme-challenge/random-filename without redirects answer with the expected http status 404 - Not Found. Creating a Letsencrypt certificate via http-01 challenge should work. If it doesn't work: Check your vHost configuration (apachectl -S, httpd -S, nginx -T). Every combination of port and ServerName / ServerAlias (Apache) or Server (Nginx) must be unique. Merge duplicated entries in one vHost. If you use an IIS, extensionless files must be allowed in the /.well-known/acme-challenge subdirectory. Create a web.config in that directory. Content: <configuration><system.webServer><staticContent><mimeMap fileExtension="." mimeType="text/plain" /></staticContent></system.webServer></configuration>. If you have a redirect http ⇒ https, that's ok, Letsencrypt follows such redirects to port 80 / 443 (same or other server). There must be a certificate. But the certificate may be expired, self signed or with a not matching domain name. Checking the validation file Letsencrypt ignores such certificate errors. 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).

| 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.

|
| 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.
|
| A | Good: Every https result with status 200 has a minified Html-Content with a quota lower then 110 %.
|
| https://nyx.mynetblog.com/ 92.38.149.105
|
| 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 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
