  • Improving System Security Through TCB Reduction

    Improving System Security Through TCB Reduction

    Improving System Security Through TCB Reduction Bernhard Kauer March 31, 2015 Dissertation vorgelegt an der Technischen Universität Dresden Fakultät Informatik zur Erlangung des akademischen Grades Doktoringenieur (Dr.-Ing.) Erstgutachter Prof. Dr. rer. nat. Hermann Härtig Technische Universität Dresden Zweitgutachter Prof. Dr. Paulo Esteves Veríssimo University of Luxembourg Verteidigung 15.12.2014 Abstract The OS (operating system) is the primary target of todays attacks. A single exploitable defect can be sufficient to break the security of the system and give fully control over all the software on the machine. Because current operating systems are too large to be defect free, the best approach to improve the system security is to reduce their code to more manageable levels. This work shows how the security-critical part of theOS, the so called TCB (Trusted Computing Base), can be reduced from millions to less than hundred thousand lines of code to achieve these security goals. Shrinking the software stack by more than an order of magnitude is an open challenge since no single technique can currently achieve this. We therefore followed a holistic approach and improved the design as well as implementation of several system layers starting with a newOS called NOVA. NOVA provides a small TCB for both newly written applications but also for legacy code running inside virtual machines. Virtualization is thereby the key technique to ensure that compatibility requirements will not increase the minimal TCB of our system. The main contribution of this work is to show how the virtual machine monitor for NOVA was implemented with significantly less lines of code without affecting the per- formance of its guest OS.

    An ECMA-55 Minimal BASIC Compiler for X86-64 Linux®

    Computers 2014, 3, 69-116; doi:10.3390/computers3030069 OPEN ACCESS computers ISSN 2073-431X www.mdpi.com/journal/computers Article An ECMA-55 Minimal BASIC Compiler for x86-64 Linux® John Gatewood Ham Burapha University, Faculty of Informatics, 169 Bangsaen Road, Tambon Saensuk, Amphur Muang, Changwat Chonburi 20131, Thailand; E-mail: [email protected] Received: 24 July 2014; in revised form: 17 September 2014 / Accepted: 1 October 2014 / Published: 1 October 2014 Abstract: This paper describes a new non-optimizing compiler for the ECMA-55 Minimal BASIC language that generates x86-64 assembler code for use on the x86-64 Linux® [1] 3.x platform. The compiler was implemented in C99 and the generated assembly language is in the AT&T style and is for the GNU assembler. The generated code is stand-alone and does not require any shared libraries to run, since it makes system calls to the Linux® kernel directly. The floating point math uses the Single Instruction Multiple Data (SIMD) instructions and the compiler fully implements all of the floating point exception handling required by the ECMA-55 standard. This compiler is designed to be small, simple, and easy to understand for people who want to study a compiler that actually implements full error checking on floating point on x86-64 CPUs even if those people have little programming experience. The generated assembly code is also designed to be simple to read. Keywords: BASIC; compiler; AMD64; INTEL64; EM64T; x86-64; assembly 1.

    x86 and C refresher Lab Background: The x86 is a very widely used microprocessor, it is in Windows and Macintosh personal computers. It is important to be familiar with Intel Architecture, IA. In this lab we will be come familiar with the Intel Architecture using debuggers, assemblers, un-assemblers, and hand assembly. These tools will allow us to enter programs, assemble, execute, debug, and modify programs. Tools and techniques develop in this lab will prepare for using microcontrollers in later labs. C programs in this lab are to refresh C programming knowledge and explore C programming used in microprocessors. Also, this x86 – C refresher Lab will be preparation for using the C programming language to program microcontrollers. Objectives: To be come familiar with how microprocessors operate. To be come familiar with programming microprocessors using machine language, assembly language, and C language. To be come proficient in the use microprocessor debugging tools and techniques. To be come familiar with assemblers and their use in programming microprocessors. To understand how to hand assemble instructions for microprocessors. To understand the program development cycle (program-test-debug- modify-test-debug-repeat until done). To use tracing charts, break points, to verify and debug programs. To develop a program from a flow chart. To write documented code with flow chart and commented code.
