Since Windows Server is typically used in production environments (Domain Controllers, File Servers, SQL Servers), USB access is usually restricted to prevent data theft and malware introduction (e.g., BadUSB, ransomware). Report ID: WS-USB-2024-001 Date: [Current Date] Author: Systems Engineering Team Target Systems: Windows Server 2019 / 2022 / 2025 1. Executive Summary This report analyzes the behavior, risks, and management strategies for USB devices (storage, input devices, dongles) connected to Windows Server environments. By default, Windows Server blocks removable storage access for non-administrative users, but critical gaps remain for privileged accounts and specific device classes. This report provides actionable recommendations to enforce USB lockdown via Group Policy, PowerShell, and third-party DLP (Data Loss Prevention) tools. 2. Default Windows Server USB Behavior Unlike Windows Client (Windows 10/11), Windows Server prioritizes security over convenience. Windows Server prioritizes security over convenience.
