USB Enforcer - Linux DLP

USB Enforcer is a comprehensive Data Loss Prevention (DLP) solution for Linux systems that prevents data exfiltration through USB mass-storage devices. It enforces encryption on all USB drives, ensuring plaintext devices remain read-only while allowing encrypted LUKS2 drives to be unlocked and used normally.

Key Features

🔒 Automatic Enforcement

Plaintext USB drives are automatically forced read-only at the block level

✅ LUKS2 Support

Encrypted drives can be unlocked and mounted with full read-write access

🎨 User-Friendly UI

GTK4/libadwaita wizard for easy drive encryption and unlocking

🔔 Desktop Notifications

Real-time alerts when blocked devices are detected

👥 Group Exemptions

Exempt specific users or groups from DLP enforcement

🖥️ Headless Support

Works on servers without GUI, with full command-line management

How It Works

  • Udev Integration: Automatically detects USB devices and applies read-only enforcement
  • PolicyKit Rules: Prevents unauthorized mounting and remounting of plaintext devices
  • Python Daemon: Monitors devices, manages encryption operations, and provides DBus API
  • Secure Communication: Passphrases never traverse the system bus, using local UNIX sockets
  • GTK Wizard: Guides users through drive encryption with optional data preservation

Supported Distributions

RPM-Based

Fedora 38+, RHEL/AlmaLinux/Rocky Linux 9+, CentOS Stream 9+, openSUSE

DEB-Based

Ubuntu 22.04+, Debian 12+, Linux Mint 21+, Pop!_OS 22.04+, Zorin OS 16+

  • RPM packages: For Fedora, RHEL, CentOS, and openSUSE systems
  • DEB packages: For Debian, Ubuntu, and derivative distributions
  • Script installation: Manual installation scripts included
  • Offline support: Bundled packages require no internet connection

Use Cases

  • Corporate Environments: Prevent sensitive data from leaving company systems via USB
  • Government & Defense: Enforce data security policies on classified systems
  • Healthcare: Protect patient data from unauthorized copying
  • Financial Services: Prevent data exfiltration of financial information
  • Education: Secure research data and student information

Windows Compatibility

Drives encrypted with USB Enforcer use LUKS2 and can be accessed on Windows through:

  • WSL2: Full native support through Windows Subsystem for Linux
  • LibreCrypt: Third-party Windows application with LUKS support
  • Cross-platform alternatives: VeraCrypt for environments requiring native Windows access

Get Involved

USB Enforcer is open-source and actively maintained. We welcome contributions including bug reports, feature requests, distribution support, and code improvements. The project includes comprehensive documentation and a full test suite.
