HTTP Strict Transport Security (HSTS)

HSTS policy for https://mailbox.org:
max-age=15768000; includeSubDomains; preload

Pass Test
max-age set to at least 6 months
includeSubDomains — policy also applies to subdomains
preload — requests inclusion in preload lists

Content Security Policy

Content Security Policy set in HTTP header: default-src 'self' data: ; img-src 'self' https://piwik.mailbox.org; script-src 'self' 'unsafe-inline' https://piwik.mailbox.org ; style-src 'self' data: 'unsafe-inline' ; frame-src 'self' https://verwaltung.mailbox.org https://status.mailbox.org; frame-ancestors 'self';

Content Security Policy (CSP) implemented unsafely. This includes 'unsafe-inline' or data: inside script-src, overly broad sources such as https: inside object-src or script-src, or not restricting the sources for object-src or script-src.

Pass Test Info
Clickjacking protection, using frame-ancestors

The use of CSP's frame-ancestors directive offers fine-grained control over who can frame your site.

Show
Deny by default, using default-src 'none'

Denying by default using default-src 'none' can ensure that your Content Security Policy doesn't allow the loading of resources you didn't intend to allow.

Show
Restricts use of the <base> tag by using base-uri 'none', base-uri 'self', or specific origins

The base tag can be used to trick your site into loading scripts from untrusted origins.

Show
Restricts where <form> contents may be submitted by using form-action 'none', form-action 'self', or specific URIs

Malicious JavaScript or content injection could modify where sensitive form data is submitted to or create additional forms for data exfiltration.

Show
Blocks loading of active content over HTTP or FTP

Loading JavaScript or plugins can allow a man-in-the-middle to execute arbitrary code on your website. Restricting your policy and changing links to HTTPS can help prevent this.

Show
Blocks loading of passive content over HTTP or FTP

This site's Content Security Policy allows the loading of passive content such as images or videos over insecure protocols such as HTTP or FTP. Consider changing them to load them over HTTPS.

Show
Uses CSP3's 'strict-dynamic' directive to allow dynamic script loading (optional)

'strict-dynamic' lets you use a JavaScript shim loader to load all your site's JavaScript dynamically, without having to track script-src origins.

Show
Blocks execution of JavaScript's eval() function by not allowing 'unsafe-eval' inside script-src

Blocking the use of JavaScript's eval() function can help prevent the execution of untrusted code.

Show
Blocks execution of inline JavaScript by not allowing 'unsafe-inline' inside script-src

Blocking the execution of inline JavaScript provides CSP's strongest protection against cross-site scripting attacks. Moving JavaScript to external files can also help make your site more maintainable.

Show
Blocks inline styles by not allowing 'unsafe-inline' inside style-src

Blocking inline styles can help prevent attackers from modifying the contents or appearance of your page. Moving styles to external stylesheets can also help make your site more maintainable.

Show
Blocks execution of plug-ins, using object-src restrictions

Blocking the execution of plug-ins via object-src 'none' or as inherited from default-src can prevent attackers from loading Flash or Java in the context of your page.

The Content Security Policy tests are based on the ones from the Mozilla HTTP Observatory scanner/grader project (Mozilla Public License 2.0) by April King, reimplemented by us for Webbkoll. The explanatory texts are from the Observatory by Mozilla website, CC-BY-SA 3.0. Any mistake or inaccuracy in the results is our fault.

Referrer Policy

Referrer Policy set to no-referrer-when-downgrade, strict-origin-when-cross-origin in Referrer-Policy HTTP header.

Subresource Integrity (SRI)

Subresource Integrity (SRI) not implemented, but all resources are loaded from a similar origin.

The Subresource Integrity test is based on the one from the Mozilla HTTP Observatory scanner/grader project (Mozilla Public License 2.0) by April King, reimplemented by us for Webbkoll.

HTTP headers

Pass Header Value Result
X-Content-Type-Options nosniff X-Content-Type-Options header set to "nosniff"
X-Frame-Options SAMEORIGIN X-Frame-Options (XFO) implemented via the CSP frame-ancestors directive
X-XSS-Protection 1; mode=block X-XSS-Protection header set to "1; mode=block"

Cookies

First-party cookies (3)

Domain Name Value Expires on HttpOnly Secure SameSite
mailbox.org csrf_https-contao_cs... cGV0jhmdMrqcBpoZed1Y... session (Lax)
.mailbox.org _pk_id.3.e25c 7dc357e5fcd23cad.156... 2020-08-12 21:00:38Z

HttpOnly means that the cookie can only be read by the server, and not by JavaScript on the client. This can mitigate XSS (cross-site scripting) attacks.

Secure means that the cookie will only be sent over a secure channel (HTTPS). This can mitigate MITM (man-in-the-middle) attacks.

SameSite can be used to instruct the browser to only send the cookie when the request is originating from the same site. This can mitigate CSRF (cross-site request forgery) attacks.

What this tool checks (and doesn't check)

This tool attempts to simulate what happens when a user visits a specified page with a typical browser. The browser has no addons/extensions installed, and Do Not Track (DNT) is not enabled, since this is the default setting in most browsers.

External files such as images, scripts and CSS are loaded, but the tool performs no interactions with the page — no links are clicked, no forms are submitted.

Disclaimer: The results presented here might not be 100% correct. Bugs happen. This tool is meant to be used by site owners as a starting point for improvements, not as a rigorous analysis.
