Measuring Security: A Challenge For The Generation, Janusz Zalewski, Steven Drager, William Mckeever, Andrew J. Kornecki Jan 2014

Measuring Security: A Challenge For The Generation, Janusz Zalewski, Steven Drager, William Mckeever, Andrew J. Kornecki

Department of Electrical Engineering and Computer Science - Daytona Beach

This paper presents an approach to measuring computer security understood as a system property, in the category of similar properties, such as safety, reliability, dependability, resilience, etc. First, a historical discussion of measurements is presented, beginning with views of Hermann von Helmholtz in his 19th century work “Zählen und Messen”. Then, contemporary approaches related to the principles of measuring software properties are discussed, with emphasis on statistical, physical and software models. A distinction between metrics and measures is made to clarify the concepts. A brief overview of inadequacies of methods and techniques to evaluate computer security is presented, followed by …

Scan Loss Pattern Synthesis For Adaptive Array Ground Stations, William C. Barott, Mary Ann Ingram, Paul G. Steffes Jul 2010

Scan Loss Pattern Synthesis For Adaptive Array Ground Stations, William C. Barott, Mary Ann Ingram, Paul G. Steffes

Publications

We present several techniques for maximizing the contact time between low Earth orbiting satellites (LEOs) and a ground station (GS). The GS comprises an adaptive array of electronically steered space-fed lenses (SFLs). Each SFL is manufactured as a low-cost printed circuit with the result that it exhibits scanning loss. By differently orienting the boresights of the SFLs in the adaptive array, the SFL's scanning losses can be made to optimally complement the path loss of the LEO, thereby reducing the cost of the GS while maximizing the download capacity of the satellite link. The optimization, implemented with a genetic algorithm …

Analyzing The Impact Of A Virtual Machine On A Host Machine, Greg Dorn, Chris Marberry, Scott Conrad, Philip Craiger Jan 2009

Analyzing The Impact Of A Virtual Machine On A Host Machine, Greg Dorn, Chris Marberry, Scott Conrad, Philip Craiger

Publications

As virtualization becomes more prevalent in the enterprise and in personal computing, there is a great need to understand the technology as well as its ramifications for recovering digital evidence. This paper focuses on trace evidence related to the installation and execution of virtual machines (VMs) on a host machine. It provides useful information regarding the types and locations of files installed by VM applications, the processes created by running VMs and the structure and identity of VMs, ancillary files and associated artifacts.

Bluetooth Hacking: A Case Study, Dennis Browning, Gary C. Kessler Jan 2009

Bluetooth Hacking: A Case Study, Dennis Browning, Gary C. Kessler

Security Studies & International Affairs - Daytona Beach

"This paper describes a student project examining mechanisms with which to attack Bluetooth-enabled devices. The paper briefly describes the protocol architecture of Bluetooth and the Java interface that programmers can use to connect to Bluetooth communication services. Several types of attacks are described, along with a detailed example of two attack tools, Bloover II and BT Info."--from the article

The Development Of Speech Research Tools On Mit's Lisp Machine-Based Workstations, D. Scott Cyphers, Robert H. Kassel, David H. Kaufman, Hong C. Leung, Mark A. Randolph, Stephanie Seneff, John E. Unverferth Iii, Timothy Wilson, Victor W. Zue Jan 1986

The Development Of Speech Research Tools On Mit's Lisp Machine-Based Workstations, D. Scott Cyphers, Robert H. Kassel, David H. Kaufman, Hong C. Leung, Mark A. Randolph, Stephanie Seneff, John E. Unverferth Iii, Timothy Wilson, Victor W. Zue

Publications

In recent years, a number of useful speech- and language-related research tools have been under development at MIT. These tools are aids for efficiently analyzing the acoustic characteristics of speech and the phonological properties of a language. They are playing a valuable role in our own research, as well as in research conducted elsewhere. This paper describes several of the systems being developed for use on our Lisp Machine workstations.
