Security System for Ad-hoc Wireless Networks
Security System for Ad-hoc Wireless Networks based on Generic Secure Objects Matei Ciobanu Morogan 2005 Ph.D. Thesis Kungliga Tekniska Högskolan Submitted as the partial fulfillment of requirements for the degree of Doctor of Philosophy at the Department of Computer and System Sciences, Kungliga Tekniska Högskolan Department of Computer and Systems Sciences Doctoral Dissertation Department of Computer and System Sciences Stockholm University / Royal Institute of Technology ISBN 91-7178-019-X i Abstract As computing devices and wireless connectivity become ubiquitous, new usage scenarios emerge, where wireless communication links between mobile devices are established in an ad-hoc manner. The resulting wireless ad-hoc networks differ from classical computer networks in a number of ways, lack of permanent access to the global network and heterogeneous structure being some of them. Therefore, security services and mechanisms that have been designed for classical computer networks are not always the optimal solution in an ad-hoc network environment. The research is focused on analyzing how standard security services that are available in classical networks can be provided in an ad-hoc wireless network environment. The goal is to design a security system optimized for operation in ad-hoc wireless networks that provides the same security services -
The Challenges of Network Security
The Challenges of Network Security Remediation at a Regional University A thesis presented to the faculty of the Department of Computer and Information Sciences East Tennessee State University In partial fulfillment of the requirements for the degree Master of Science in Computer Science by William R. Simons May 2005 Dr. Qing Yuan, Chair Dr. Phillip Pfeiffer Mr. Steven Jenkins Keywords: computer, system security, network security, security audit, security hardening, vulnerability, remediation, Nessus, Nmap 2 ABSTRACT The Challenges of Network Security Remediation at a Regional University by William R. Simons This thesis describes challenges encountered during a year-long effort to improve the security of the 3,300 node administrative computer network at East Tennessee State University. The key remediation strategies used included employing the vulnerability scanner Nessus to profile the network, analyzing the scan results, and attempting to remove the most critical vulnerabilities found. The project succeeded in decreasing known "high" criticality vulnerabilities on campus by 26.1%, and confirmed four standard observations about the challenges of network administration: Vulnerability scanning is a lengthy task best performed in parallel and supported by automated data analysis. Securing a network is like trying to hit a moving target, due to an

Issues and Applications of Grid Computing A thesis submitted in partial fulfillment of the requirements for the degree of Bachelor of Science (Computer Science) ABSTRACT The intention of this study is to analyze and explore the emerging field of grid technology. It delves into how the grid is being used to enhance the capabilities of existing distributed systems and data resources. The characteristics of virtual organizations and their participation in implementing a grid structure are observed. The issues surfacing in grid implementation and their possible solutions are discussed. Enhancements and modifications are proposed for existing frameworks for database integration with the grid. A basic grid structure for the Department of Computer Science, University of Karachi has been planned out. The Globus Toolkit, used in grid middleware is tested and run on available resources.

Introduction "Every picture tells a story" An old saying that holds true. A picture can tell us more in an instant than a thousand words ever could. A picture records emotions, expressions, feelings and conveys them easily to the onlooker. Photographs capture hundreds of years of history be it on a world scale or at a personal level. We capture our weddings, births, birthdays and other occasions dear to us on camera because we want to hold on to that moment forever. Every time we look at a photograph we remember that day and relive that moment. The camera never lies. It takes a moment in time and freezes it. We rely on photographs as a tool to help us to understand and to remember the history of the world. Most of the worlds great historical events have been captured on film. A photograph of an innocent victim of war makes the victim real, like someone we knew rather than a name in a paper, and touches us far more deeply than stories in a book. Peoples descriptions of events are often tainted by exaggeration, imperfect memories and personal opinions but there is no denying the evidence of a photograph. The camera has come along way since the days of Niepcei. The first cameras were big and

Security in Wireless Local Area Networks
Security in Wireless Local Area Networks Sami Uskela Department of Electrical and Communications Engineering Helsinki University of Technology [email protected] Abstract When the wireless communications is coming to the offices and the homes, there are some new security issues to be taken care of. Today we have continuously growing markets for the wireless LANs, but there is big black hole in the security of this kind of networks. This paper gives an overview of the security functions specified in two wireless LAN standard, namely in the IEEE 802.11 and the HIPERLAN. There is also some discussion about the threats and vulnerabilities in wireless networks compared to wired networks. And last but not least the protocols and mechanisms needed in the secure wireless LAN are described.
