A | lthhome.top 114.219.59.196
| Content-Security-Policy
| Ok: Header without syntax errors found: default-src 'self'; base-uri 'self'; form-action 'self'; object-src 'self' blob:; script-src 'self' 'wasm-unsafe-eval'; style-src 'self' 'unsafe-inline'; child-src 'self' https://*.duosecurity.com https://*.duofederal.com; frame-src 'self' https://*.duosecurity.com https://*.duofederal.com; frame-ancestors 'self' chrome-extension://nngceckbapebfimnlniiiahkandclblb chrome-extension://jbkfoedolllekgbhcbcoahefnbanhhlh moz-extension://* ; img-src 'self' data: https://haveibeenpwned.com ; connect-src 'self' https://api.pwnedpasswords.com https://api.2fa.directory https://app.simplelogin.io/api/ https://app.addy.io/api/ https://api.fastmail.com/ https://api.forwardemail.net ;
|
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.
|
F |
|
| Critical: object-src with a scheme definition found. That's too global, don't use such a definition. Use a list of urls instead if you really want to use object / embed / applet.
|
A |
|
| Good: script-src without 'unsafe-inline' and 'unsafe-eval' found. That's the recommended configuration.
|
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.

A | Info:: 4 Queries complete, 4 with IPv6, 0 with IPv4.
|
A | Good: All DNS Queries done via IPv6.
|
| Ok (4 - 8):: An average of 4.0 queries per domain name server required to find all ip addresses of all name servers.

|
A | Good: Only one SOA.Primary Name Server found.: dns1.hichina.com.
|
A | Good: SOA.Primary Name Server included in the delegation set.: dns1.hichina.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
|
|
|
| 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.: 1 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: hichina.com

|
| Warning: https result with status 200 and size greater then 1024 Bytes without Compression found. Add Compression support (gzip, deflate, br - these are checked) so the html content is compressed.
|
A | Good: No https + http status 200 with inline CSS / JavaScript found
|
A | Good: Every https result with status 200 has a minified Html-Content with a quota lower then 110 %.
|
| https://lthhome.top:3014/ 114.219.59.196
|
| 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 files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 5 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, 5 complete.
|
A | Good: All checked attribute values are enclosed in quotation marks (" or ').
|
A | Good: All img-elements have a valid alt-attribute.: 1 img-elements 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
