# User Access Control (UAC)

## Overview

Nosto's UGC User Access Control is a security infrastructure that enables Enterprise clients to define appropriate custom access rules for specific resources within the Platform.

The rules, which are defined for a User Group, allow clients to customize access conditions on both the API (Back-End) and the Nosto Admin Portal (Front-End) level.

Rules for the API can be set on a Coarse-Grain level, whilst many areas of Nosto's UGC Admin User Interface allow for Fine-Grain rules to be applied.

## Scopes

The Scope refers to the section of the Nosto's UGC Platform that you wish to apply the Access Control permissions to.

Whilst broken into separate sections within the UI, it is important to note, that conditions applied in one scope can have an impact on the user experience in another.

## 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://docs.nosto.com/ugc/enterprise/uac.md?ask=<question>&goal=<endgoal>
```

`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.
