# Fernzugriff (Remote Access)

**Fernzugriff** (Remote Access) refers to the methods, tools, and ability provided by the university to allow members to access internal university resources and utilize the IT services of the Universität Greifswald from external locations.

The [[universitatsrechenzentrum-urz]] provides dedicated documentation for establishing remote access.

## Technical Requirements
To ensure a smooth user experience, the Universitätsrechenzentrum (URZ) specifies a minimum stable internet connection speed/bandwidth of **2Mbit/s**. Access is supported across various end-devices, including PCs, tablets, and smartphones.

## Access Tiers
The university divides its service landscape into two primary accessibility tiers:

### 1. Public Services
These services are available globally via the internet without requiring a VPN or additional authentication tunnels:
- **Communication**: Email, [[instant-messaging]], [[xmpp]], [[matrix]], and Web Conferencing.
- **Learning & Administration**: [[moodle]] and the [[selbstbedienungsportal]].
- **Collaboration**: [[nextcloud]].

### 2. Internal Services
These services are restricted to the university's internal network for security reasons. Access from external locations requires a secure tunnel, primarily via a [[vpn]] connection:
- **Storage**: [[zentrale-datenspeicherung]] (Network drives / central file storage).
- **Data**: Internal databases.

## Remote Work Methods and Distinctions

### Access Methods
Depending on the need, users can employ different methods of remote access:
- **VPN-based Access**: Used to connect a local device to the internal network to reach specific servers or drives. This typically includes the configuration of a [[vpn]] (Virtual Private Network) to create a secure tunnel into the campus network.
- **Telearbeit (VDI)**: A specialized form of remote access using Virtual Desktop Infrastructure to access a specific professional workstation computer.

### Service Access vs. Workplace Access
It is important to distinguish between accessing specific services and accessing a full workstation:
- **Service Access**: Using a VPN or public web interface to use a specific tool (e.g., Nextcloud).
- **Workplace Access**: Using [[telearbeit]] (VDI) to remotely control a physical workplace computer.

## Collaboration Best Practices
To optimize data management and security, the URZ recommends avoiding the use of email attachments for group work. Instead, the following are recommended:
- **Network Drives**: For internal file exchange.
- **Nextcloud**: For cloud-based file sharing and collaboration.
