# Antivirus Requirements by OS

The [[universitatsrechenzentrum-urz]] maintains a differentiated security posture regarding the necessity of antivirus software based on the operating system in use.

## OS-Specific Requirements

| Operating System | Requirement | Recommended Tool | Basis/Reasoning |
|------------------|-------------|-------------------|-------------------|
| **Windows 10/11** | Mandatory | [[windows-defender]] | [[bsi-it-grundschutz]] (SYS.2.2.3.A5) |
| **Windows Server**| Mandatory | [[clamwin]] (Alternative) | General server security |
| **macOS** | Not Required | N/A | URZ institutional perspective |
| **Linux** | Not Required | N/A | URZ institutional perspective |

This policy indicates that while Windows systems are viewed as requiring active malware protection to meet national standards, [[macos]] and [[linux]] are considered sufficiently secure from the URZ's perspective without additional antivirus software.
