Microkernel Mechanisms for Improving the Trustworthiness of Commodity Hardware
Microkernel Mechanisms for Improving the Trustworthiness of Commodity Hardware Yanyan Shen Submitted in fulfilment of the requirements for the degree of Doctor of Philosophy School of Computer Science and Engineering Faculty of Engineering March 2019 Thesis/Dissertation Sheet Surname/Family Name : Shen Given Name/s : Yanyan Abbreviation for degree as give in the University calendar : PhD Faculty : Faculty of Engineering School : School of Computer Science and Engineering Microkernel Mechanisms for Improving the Trustworthiness of Commodity Thesis Title : Hardware Abstract 350 words maximum: (PLEASE TYPE) The thesis presents microkernel-based software-implemented mechanisms for improving the trustworthiness of computer systems based on commercial off-the-shelf (COTS) hardware that can malfunction when the hardware is impacted by transient hardware faults. The hardware anomalies, if undetected, can cause data corruptions, system crashes, and security vulnerabilities, significantly undermining system dependability. Specifically, we adopt the single event upset (SEU) fault model and address transient CPU or memory faults. We take advantage of the functional correctness and isolation guarantee provided by the formally verified seL4 microkernel and hardware redundancy provided by multicore processors, design the redundant co-execution (RCoE) architecture that replicates a whole software system (including the microkernel) onto different CPU cores, and implement two variants, loosely-coupled redundant co-execution (LC-RCoE) and closely-coupled redundant co-execution (CC-RCoE), for the ARM and x86 architectures. RCoE treats each replica of the software system as a state machine and ensures that the replicas start from the same initial state, observe consistent inputs, perform equivalent state transitions, and thus produce consistent outputs during error-free executions. -

How to Create a Custom Live CD for Secure Remote Incident Handling in the Enterprise
How to Create a Custom Live CD for Secure Remote Incident Handling in the Enterprise Abstract This paper will document a process to create a custom Live CD for secure remote incident handling on Windows and Linux systems. The process will include how to configure SSH for remote access to the Live CD even when running behind a NAT device. The combination of customization and secure remote access will make this process valuable to incident handlers working in enterprise environments with limited remote IT support.

Chapter 2 - Location and coordinates Updated 10 July 2006 -4 -3 -2 -1 0 +1 +2 +3 +4 Figure 2.1 A simple number line acts as a one-dimensional coordinate system. Each number describes the distance of a particular point-location from the origin, or zero. The unit of measure for the distance is arbitrary. 10 9 8 (4.5,7.5) 7 6 s i x a (3,5) - 5 y 4 3 (6,3) 2 1 0 0 1 2 3 4 5 6 7 8 9 10 x - axis Figure 2.2 Here is a simple x-y coordinate system with the coordinates of a few points shown as examples. Coordinates are given as an ordered pair of numbers, with the x-coordinate first. The origin is the lower left, at (0,0). The reference lines are the x and y axes. All grid lines are drawn parallel to the two reference lines. The purpose of the grid is to make it easier to make distance measurements between a location-point and the reference lines. 5 4 3 (2,3) 2 s 1 i x a (-2,0) - 0 y -1 -2 (1,-2) -3 -4 -5 -5 -4 -3 -2 -1 0 1 2 3 4 5 x - axis Figure 2.3 A more general coordinate grid places the origin (0,0) at the center of the grid. The coordinates may have either positive or negative values. The sign merely indicates whether the point is left or right (x), or above or below (y) the axis. -

It consists of a humorous 24-minute show and educator’s package. The Orion Educator’s Guide is designed for Planetarians, Teachers, and parents. The information is researched, organized, and laid out so that the educator need not spend hours coming up with lesson plans or labs. This has already been accomplished by certified educators. The guide is written to alleviate the fear of space and the night sky (that many elementary and middle school teachers have) when it comes to that section of the science lesson plan. It is an excellent tool that allows the parents to be a part of the learning experience. The guide is devised in such a way that there are plenty of visuals to assist the educator and student in finding the Winter constellations.
