About This Guide

This guide has one specific goal: help you build and operate an encrypted Arch Linux system on a portable SATA-to-USB drive so that if the drive is physically seized by an authoritarian authority, they obtain nothing useful.

It covers the complete picture — from choosing hardware through emergency destruction — organized as a linear book you can follow from beginning to end, or reference chapter by chapter when you need a specific procedure.

What this guide covers:

• Hardware selection and SATA-to-USB enclosure setup
• Full-disk encryption that resists offline brute-force at any scale
• Anti-forensic techniques tailored to how state forensics actually works — not how it is portrayed in television
• Plausible deniability: how to make the drive appear to contain something harmless even if you are forced to unlock it
• Boot security that detects and resists tampering while you are away from the device
• Network anonymization for the actual use of the machine
• Emergency destruction procedures for when physical security fails
• Legal frameworks and what to say — and not say — under duress

What this guide does not cover: This is not a general Linux security guide, a penetration-testing manual, or an offensive security resource. Every chapter exists to solve one specific problem: protecting a portable encrypted drive from a state adversary who can seize it, image it, and attack it offline.
