# Permissions

StifleR controls access to the two main server components, i.e the SignalR Hub and the Web service. This control applies to both users (who access StifleR Dashboards) and StifleR Clients (who access the SignalR Hub).

### User Access Control

Access to the StifleR Server service is controlled by AD Global group memberships. During the [StifleR Server installation](/stifler/2.10/installation/server/stifler-server-installation.md), an admin can set the value for the AD Global groups representing specific administrative roles. By default, the installer provides assumed names for these AD Global groups, which are listed in the table below. The group names are written to the [StifleR Server Configuration file](/stifler/2.10/configuration/configuration-files/stifler-server-configuration-file.md) which can be modified after the installation.

| Group                        | Description                                                            | Access                                                                    |
