# Security
The Security tab brings together three types of configuration: Trust center owner management, document access control, and IP address filtering.
## Trust center owners
You can designate **one or more owners** for your Trust center. Owners receive document access requests and can approve or decline them from a dedicated screen in the Trust center module.
Configuring owners and access control in the Security tab
## Document access control
By default, an **access confirmation** is required before visitors can download documents published in the Trust center. This behaviour can be configured in the Security section.
When document access control is enabled:
1. Visitors can see the list of available documents, but must submit an **access request** by providing their email address and the reason for their request.
2. Trust center owners receive an email and can **manage access requests** from the administration interface.
3. If the request is approved, the visitor receives an email containing a **download link valid for 30 days**.
{% hint style="info" %}
If no owner is designated, access requests cannot be processed. Make sure at least one active owner is always assigned.
{% endhint %}
## IP address filtering
This section also allows you to define rules that limit access to your Trust center to specific IP ranges. By default, without any IP filtering added by you, your Trust center will be accessible to anyone with the access link, provided that the Trust center is activated.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://doc.dastra.eu/en/features/privacy-hubs/configuration/security.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
