# Device Registration

**Device Registration** (Geräteregistrierung) is the process of associating a device's unique hardware address (MAC address) with a user account. Depending on the source, its primary purpose is described as:
- Authorizing a specific piece of hardware for OS installation via the [[device-management-system]].
- Authorizing full access to the university's wired network infrastructure.

## Purpose and Compliance
The [[universitatsrechenzentrum-urz]] implements this process to comply with security recommendations from the **Bundesamt für Sicherheit in der Informationstechnik (BSI)**. This ensures that only known and authorized official devices have unrestricted access to the internal data network.

## Scope and Enforcement
- **Applicability**: Required for all devices connected via LAN cable to a data socket or telephone.
- **Exclusions**: Devices in student dormitories are excluded from this specific registration requirement.
- **Enforcement**: Devices that are not registered do not receive full network access. Instead, they are routed to the [[guest-network]], where permissions are severely limited, potentially blocking access to internal resources and network drives.

## Registration Process
Registration is performed via the account management system.

### Self-Service Workflow (via [[ums]])
Users can register via the [[ums]] portal:
1. Log into the **UMS**.
2. Navigate to: `Meine Ressourcen` $\rightarrow$ `Ressource beantragen` $\rightarrow$ `Geräteregistrierung`.
3. Provide the device's **MAC address**.
4. Specify the **purpose of use** (Official vs. Private).

### Required Details for OS Installation
When requesting registration for OS installation, users must provide:
- **Hardware Identifiers**: Manufacturer, type, serial number, and inventory number (if available).
- **Description**: A brief identifier to recognize the machine later.
- **Installation Parameters**:
    - Target operating system language.
    - Operating system (Linux or Windows).
    - Service level ([[concepts/windows-vollservice]] or [[concepts/basisservice-definition-2026-07-01-064728]]).
    - Profile (typically "Allgemein").

## Technical Basis
The registration relies on the **MAC Address**, a unique hardware identifier assigned by the manufacturer. The [[universitatsrechenzentrum-urz]] uses this address to identify and deliver data to the specific device on the local network.
