| How to enable USB security on Windows |
Introduction
USB devices are convenient for transferring files, but they also pose serious security risks. A single infected USB drive can introduce malware, ransomware, or keyloggers into your system. Worse, an unauthorized person can plug in a USB and steal sensitive data.
To prevent these risks, enabling USB security on Windows is essential. This guide will show you how to secure USB ports, block unauthorized access, and protect your computer from USB-based threats.
Why You Need USB Security on Windows
Hackers and cybercriminals use USB devices as attack vectors to:
🚨 Spread Malware & Viruses – USB drives can infect systems with ransomware or trojans.
🚨 Steal Sensitive Data – Attackers can copy files without leaving traces.
🚨 Launch Keyloggers & Spyware – USBs can inject scripts that monitor keystrokes.
🚨 Compromise Network Security – Infected USBs can spread malware across networks.
Enabling USB security helps prevent these risks and keeps your data safe.
