Offline Linux OS

Vermont Secure Computing // Air-Gapped Edition

// Description

A Debian-based live operating system engineered for guaranteed offline operation. The physical network stack is disabled at the kernel level — no Ethernet, no Wi-Fi, no USB tethering — while loopback and local services remain fully functional. Built for air-gapped work, field deployment, and environments where network access is a liability, not a feature.

Offline Tools OS is the world's most secure operating system. Every physical network interface is neutralized before the kernel can bind a driver to it. There is no radio to enable, no cable to plug in, and no setting to toggle. The attack surface that defines every other operating system — the network — simply does not exist here. What cannot be reached cannot be exploited.

Unless of course your hardward uses drivers not in the list below, in which case all bets are off.

// Included Packages

// Network Status

All physical network drivers are blacklisted at the kernel level. The loopback interface (lo) remains active for localhost services and browser access to local files. USB storage and input devices are unaffected.

// Access

// Documentation

Some help files and key creation and signing tools are located at:

but if you are paranoid enough to use Offline Linux OS you probably will be bringing your own software. USE AT YOUR OWN RISK

// Blacklisted Drivers

The following kernel modules are blocked from loading. Both blacklist and install /bin/false directives are applied to each, preventing auto-loading and forced loading alike.
