Operating System Boot from Fully Encrypted Device
Masaryk University Faculty of Informatics Operating system boot from fully encrypted device Bachelor’s Thesis Daniel Chromik Brno, Fall 2016 Replace this page with a copy of the official signed thesis assignment and the copy of the Statement of an Author. Declaration Hereby I declare that this paper is my original authorial work, which I have worked out by my own. All sources, references and literature used or excerpted during elaboration of this work are properly cited and listed in complete reference to the due source. Daniel Chromik Advisor: ing. Milan Brož i Acknowledgement I would like to thank my advisor, Ing. Milan Brož, for his guidance and his patience of a saint. Another round of thanks I would like to send towards my family and friends for their support. ii Abstract The goal of this work is description of existing solutions for boot- ing Linux and Windows from fully encrypted devices with Secure Boot. Before that, though, early boot process and bootloaders are de- scribed. A simple Linux distribution is then set up to boot from a fully encrypted device. And lastly, existing Windows encryption solutions are described. iii Keywords boot process, Linux, Windows, disk encryption, GRUB 2, LUKS iv Contents 1 Introduction ............................1 1.1 Thesis goals ..........................1 1.2 Thesis structure ........................2 2 Boot Process Description ....................3 2.1 Early Boot Process ......................3 2.2 Firmware interfaces ......................4 2.2.1 BIOS – Basic Input/Output System . .4 2.2.2 UEFI – Unified Extended Firmware Interface .5 2.3 Partitioning tables ......................5 2.3.1 MBR – Master Boot Record . -

chapter 3 Installing Fedora Now comes the moment of truth. You’ve done the homework, figured out how you want to install your copy of Fedora, and you’re ready to go. This chapter won’t disappoint you. Its sole goal is to walk you through the installation process using the Anaconda graphical installer. Along the way, you will: ■ Discover how to explore Fedora—without installing it. ■ Choose which option will be best for you, installing Fedora alone or along- side another operating system. ■ Journey step by step through the installation process. ■ Create one or more users for your Fedora machine. Try Before You Buy © Cengage Learning. All rights reserved. No distribution allowed without express authorization. This section may leave you scratching your head and wondering why you just went through all of the preparation in Chapter 2. Be patient, there’s a method to this madness. All spins of Fedora are currently available to users as a LiveCD version. “LiveCD” is the label for operating systems that can be booted and run right from the CD itself—without installing on your computer’s hard drive. 41 Game Developing GWX Not For Sale Not For Sale 42 Chapter 3 ■ Installing Fedora This means that when you insert your Fedora CD into the disc drive and restart your computer, Fedora will automatically begin running on your computer without putting on any new files or touching pre-existing data on your machine. Fedora just starts up and runs. So why, you ask, should I bother installing Fedora at all? I can just run it from the CD. -
White Paper: Indestructible Firewall in a Box V1.0 Nick Mccubbins
White Paper: Indestructible Firewall In A Box v1.0 Nick McCubbins 1.1 Credits • Nathan Yawn ([email protected]) 1.2 Acknowledgements • Firewall-HOWTO • Linux Router Project • LEM 1.3 Revision History • Version 1.0 First public release 1.4 Feedback • Send all information and/or criticisms to [email protected] 1.5 Distribution Policy 2 Abstract In this document, the procedure for creating an embedded firewall whose root filesystem is loaded from a flash disk and then executed from a RAMdisk will be illustrated. A machine such as this has uses in many environments, from corporate internet access to sharing of a cable modem or xDSL connection among many computers. It has the advantages of being very light and fast, being impervious to filesystem corruption due to power loss, and being largely impervious to malicious crackers. The type of firewall illustrated herein is a simple packet-filtering, masquerading setup. Facilities for this already exist in the Linux kernel, keeping the system's memory footprint small. As such the device lends itself to embedding very well. For a more detailed description of firewall particulars, see the Linux Firewall-HOWTO. 3 Equipment This project has minimal hardware requirements. An excellent configuration consists of: For a 100-baseT network: • SBC-554 Pentium SBC with PISA bus and on-board PCI NIC (http://www.emacinc.com/pc.htm#pentiumsbc), approx. $373 • PISA backplane, chassis, power supply (http://www.emacinc.com/sbcpc_addons/mbpc641.htm), approx. $305 • Second PCI NIC • 32 MB RAM • 4 MB M-Systems Flash Disk (minimum), approx. $45 For a 10-baseT network: • EMAC's Standard Server-in-a-Box product (http://www.emacinc.com/server_in_a_box.htm), approx. -
Chapter 3. Booting Operating Systems
Chapter 3. Booting Operating Systems Abstract: Chapter 3 provides a complete coverage on operating systems booting. It explains the booting principle and the booting sequence of various kinds of bootable devices. These include booting from floppy disk, hard disk, CDROM and USB drives. Instead of writing a customized booter to boot up only MTX, it shows how to develop booter programs to boot up real operating systems, such as Linux, from a variety of bootable devices. In particular, it shows how to boot up generic Linux bzImage kernels with initial ramdisk support. It is shown that the hard disk and CDROM booters developed in this book are comparable to GRUB and isolinux in performance. In addition, it demonstrates the booter programs by sample systems. 3.1. Booting Booting, which is short for bootstrap, refers to the process of loading an operating system image into computer memory and starting up the operating system. As such, it is the first step to run an operating system. Despite its importance and widespread interests among computer users, the subject of booting is rarely discussed in operating system books. Information on booting are usually scattered and, in most cases, incomplete. A systematic treatment of the booting process has been lacking. The purpose of this chapter is to try to fill this void. In this chapter, we shall discuss the booting principle and show how to write booter programs to boot up real operating systems. As one might expect, the booting process is highly machine dependent. To be more specific, we shall only consider the booting process of Intel x86 based PCs. -

Revision 0.1.1 2001−04−09 Revised by: logilab First public draft. Revision 0.1 2000−12−09 Revised by: bej Initial draft. This document explains how to quickly setup a linux server to provide what diskless linux clients require to get up and running, using an IP network. It includes data and partly rewritten text from the Diskless−HOWTO, the Diskless−root−NFS−HOWTO, the linux kernel documentation, the etherboot project's documentation, the linux terminal server project's homepage, and the author's personal experience, acquired when working for Logilab. Eventually this document may end up deprecating the Diskless−HOWTO and Diskless−root−NFS−HOWTO. Please note that you'll also find useful information in the From−PowerUp−to−bash−prompt−HOWTO and the Thin−Client−HOWTO, and the Claus−Justus Heine's page about NFS swapping.
