Define the Trusted Computing Base (TCB) and explain why minimizing its size is a fundamental security principle.

Analyze the attack surface of a typical consumer laptop, identifying potential points of compromise from hardware to software.

Explain the role of the BIOS/UEFI in the computer's boot sequence.

Describe the security risks associated with proprietary, closed-source firmware.

Define the Intel Management Engine (ME) and explain its function as an autonomous subsystem within Intel chipsets.

Analyze the security and privacy implications of the Intel ME, referencing known vulnerabilities and its potential as a backdoor.

Introduce Coreboot as an open-source firmware alternative and explain its benefits in terms of transparency, configurability, and attack surface reduction.

Research the specific hardware components of your x230 to confirm Coreboot compatibility and identify the correct flashing procedure.

Identify the tools required for external flashing (e.g., Raspberry Pi, SOIC8 clip, jumper wires) and explain the function of each.

Explain the purpose of the 'me_cleaner' script and how it neutralizes the Intel ME by removing most of its code modules.

Set up the Coreboot build environment by installing the required toolchain and cloning the source code.

Create and verify multiple redundant backups of the original proprietary BIOS firmware.

Produce a neutralized Intel ME firmware region using the 'me_cleaner' script on a backed-up BIOS image.

Configure the Coreboot build for the x230, selecting a payload (e.g., SeaBIOS) and specifying the neutralized ME region.

Compile the configured source code to produce a final Coreboot ROM image.

Create a detailed disassembly plan for the x230 to safely access the motherboard and BIOS chip, referencing service manuals.

Explain and apply electrostatic discharge (ESD) prevention measures for safe handling of electronic components.

Execute the disassembly of the x230 and physically locate the 8-pin BIOS chip on the motherboard.

Assemble the flashing apparatus by correctly connecting the SOIC8 clip to the Raspberry Pi's GPIO pins.

Use the 'flashrom' utility to test the connection to the BIOS chip.

Flash the custom, neutralized Coreboot image onto the BIOS chip using 'flashrom'.

Re-assemble the x230 hardware, ensuring all internal connectors are properly seated.

Perform the initial boot test and diagnose common Coreboot first-boot issues (e.g., memory training hangs, no video output).

Define 'security by compartmentalization' and explain how virtualization can be used to enforce it.

Compare the security models of monolithic OSs with a virtualization-based OS like Qubes OS.

Describe the architecture of Qubes OS, including the roles of Dom0, TemplateVMs, and AppVMs.

Explain the principle of Full Disk Encryption (FDE) and how it protects data 'at rest' against physical compromise.

Explain the roles of cryptographic hashes and digital signatures in verifying software authenticity and integrity.

Create a bootable Qubes OS installation USB drive.

Use GPG to verify the cryptographic signature of the downloaded Qubes OS ISO image.

Install Qubes OS on the x230, configuring LUKS-based Full Disk Encryption with a strong passphrase.

Manage the AppVM lifecycle by creating, starting, stopping, and deleting an AppVM.

Explain the relationship between TemplateVMs and AppVMs for managing software and updates.

Install a new application in a TemplateVM to make it available to linked AppVMs.

Create and label at least two separate AppVMs (e.g., 'work', 'personal-banking') to practice the principle of compartmentalization.

Use a DisposableVM in Qubes OS to safely open a potentially malicious document downloaded from the internet.

Explain the fundamental principles of onion routing and how the Tor network provides anonymity.

Analyze the limitations and potential weaknesses of the Tor network, such as traffic correlation and malicious exit nodes.

Define the role of Whonix and explain how its Gateway-Workstation architecture isolates network traffic and prevents IP address leaks.

Install the Whonix Gateway and Workstation templates within Qubes OS.

Create a new AppVM based on the Whonix Workstation template for anonymous browsing.

Demonstrate the use of the Tor Browser within a Whonix AppVM, explaining the function of its different security levels.

Route the traffic of a standard Fedora AppVM through the Whonix Gateway to 'torify' a non-Whonix application.

Define Operational Security (OpSec) and provide examples of how user behavior can undermine strong technical security measures.

Explain the concept of browser fingerprinting and how it can be used to de-anonymize users, even over Tor.

Explain the security risks of file metadata and demonstrate how to view and strip metadata from common file types.

Articulate a set of personal OpSec rules for maintaining anonymity, such as avoiding logging into personal accounts over Tor and not mixing identities between Qubes.
