| 1. General Results, most used to calculate the result |
| A | name "jira.esss.lu.se" is subdomain, public suffix is ".se", top-level-domain is ".se", top-level-domain-type is "country-code", Country is Sweden, tld-manager is "The Internet Infrastructure Foundation", num .se-domains preloaded: 829 (complete: 199710)
|
| A | Good: All ip addresses are public addresses
|
| Warning: Only one ip address found: jira.esss.lu.se 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: jira.esss.lu.se 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 | https://jira.esss.lu.se/ 193.11.102.19
| https://jira.esss.lu.se/plugins/servlet/samlsso?redirectTo=%2F
| Correct redirect https to https
|
| 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: No cookie sent via http.
|
| 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.

| Error - Certificate isn't trusted, RemoteCertificateNameMismatch
|
| X | Fatal error: Nameserver doesn't support TCP connection: esss.lu.se / 194.47.240.234: Timeout
|
| X | Fatal error: Nameserver doesn't support TCP connection: ns1.srv.lu.se / 2001:6b0:16:1:0:1000:3:a: Timeout
|
| X | Fatal error: Nameserver doesn't support TCP connection: ns2.srv.lu.se / 2001:6b0:16:1:0:1000:3:b: Timeout
|
| 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 jira.esss.lu.se, 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.jira.esss.lu.se
|
| 2. Header-Checks (Cross-Origin-* headers are alpha - started 2024-06-05) |
| A | jira.esss.lu.se
| Content-Security-Policy
| Ok: Header without syntax errors found: frame-ancestors confluence-staging.ess.eu confluence.esss.lu.se confluence.ess.eu jira.esss.lu.se jira.ess.eu jira-edmz.ess.eu
|
| 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.
|
| 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
|
| F | jira.esss.lu.se
| Permissions-Policy
| Critical: Missing Header:
|
| A |
| X-Frame-Options
| 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.
|
| A |
| X-Xss-Protection
| Ok: Header without syntax errors found: 1; mode=block
|
| B |
|
| Info: Header is deprecated. May not longer work in modern browsers. 1; mode=block

| 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.esss.se (194.47.240.197), sunic.sunet.se (192.36.125.2, 2001:6b0:7::2)
|
| 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:: 3 different Name Servers found: esss.lu.se, ns1.esss.se, sunic.sunet.se, 2 Name Servers included in Delegation: ns1.esss.se, sunic.sunet.se, 2 Name Servers included in 2 Zone definitions: ns1.esss.se, sunic.sunet.se, 1 Name Servers listed in SOA.Primary: esss.lu.se.
|
| A | Good: Only one SOA.Primary Name Server found.: esss.lu.se.
|
| Error: SOA.Primary Name Server not included in the delegation set.: esss.lu.se.
|
| 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: 2 Name Servers, 2 different subnets (first Byte): 192., 194., 2 different subnets (first two Bytes): 192.36., 194.47., 2 different subnets (first three Bytes): 192.36.125., 194.47.240.
|
| A | Excellent: Every Name Server IPv4-address starts with an unique Byte.
|
| A | Info: IPv6-Subnet-list: 1 Name Servers with IPv6, 1 different subnets (first block): 2001:, 1 different subnets (first two blocks): 2001:06b0:, 1 different subnets (first three blocks): 2001:06b0:0007:, 1 different subnets (first four blocks): 2001:06b0:0007:0000:

| 4. Content- and Performance-critical Checks |
| https://jira.esss.lu.se/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de
|
| Fatal: Check of /.well-known/acme-challenge/random-filename is blocked, http connection error. 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://jira.esss.lu.se/plugins/servlet/samlsso?redirectTo=%2F
|
| 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://jira.esss.lu.se/plugins/servlet/samlsso?redirectTo=%2F
|
| 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.
|
| https://jira.esss.lu.se/plugins/servlet/samlsso?redirectTo=%2F
|
| 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.
|
| A | Good: All CSS / JavaScript files are sent compressed (gzip, deflate, br checked). That reduces the content of the files. 1 external CSS / JavaScript files found
|
| A | Good: All CSS / JavaScript files are sent with a long Cache-Control header (minimum 7 days). So the browser can re-use these files, no download is required. 1 external CSS / JavaScript files with long Cache-Control max-age found
|
| 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
