# FAQ Sicherheit

This source provides security guidance and technical "how-to" instructions for users of the Universität Greifswald IT infrastructure, focusing on endpoint security, privacy, and web safety.

## Key Content Areas

### Windows 10 Privacy and Hardening
- **Telemetry:** Explains that Windows 10 automatically transmits diagnostic and usage data to Microsoft. It provides methods to restrict this:
    - **Standard Settings:** Via Privacy settings (limited restriction).
    - **Enterprise:** Using `gpedit.msc` (Group Policy Editor).
    - **Home/Pro/Education:** Using `regedit` (Registry Editor) to set `AllowTelemetry` to 0 and disabling specific services (`Diagnoseverfolgungsdienst`, `dmwappushsvc`, etc.).
- **Managed Devices:** Notes that devices registered in the `uni-greifswald.de` domain and connected to the university network have telemetry restricted centrally via Group Policy.
- **OneDrive:** Provides a reference to Microsoft support for disabling or uninstalling the integrated cloud storage service.

### General Security Awareness
- **File Extensions:** Instructions for showing file name extensions in Windows Explorer (Windows 7, 8.x, and 10) to help users identify suspicious files.
- **Web Security:** 
    - Guidance on identifying secure (encrypted) connections via the "lock" symbol in the browser address bar.
    - A specific rule for verifying legitimate university websites: ensuring the domain ends with a trailing slash (`/`) immediately after `.de`.
- **Office Macros:** Directs users to official LibreOffice and Microsoft Support documentation for activating or disabling macros to prevent malicious code execution.

### URZ Support Channels
- **Ticket System:** Integrated into the [[groupware]] platform.
- **Hotline:** Available at extension **1420**.
