# Content Security Policy (CSP)

Wenn Sie die Durchsetzung einer Content Security Policy (CSP) in den Browsern der Benutzer benötigen, können Sie CSP in ngSurvey mithilfe der folgenden Umgebungsvariable aktivieren.

**`NGSurvey:CPSPolicy`**muss auf "Self" gesetzt werden, um die Content Security Policy (CSP) im Browser durchzusetzen. 

Beachten Sie, dass Ihre CSP unsichere Inline-CSS-Stile zulassen muss:

```
style-src 'self' 'unsafe-inline';
```

{% hint style="warning" %}
Widget-basierte Antwort-Elemente und alle benutzerdefinierten JavaScript-bezogenen Funktionen wie Formular-Codes und benutzerdefinierte Antwortvalidierungen werden deaktiviert, wenn auf Self gesetzt. 
{% endhint %}
