The Importance Of Human Factors When Assessing Outsourcing Security Risks, Carl Colwill, Andy Jones
The Importance Of Human Factors When Assessing Outsourcing Security Risks, Carl Colwill, Andy Jones
Australian Information Security Management Conference
The word is becoming increasingly interconnected and ways of doing business are evolving rapidly. Communications technology is ubiquitous and reliable and businesses are continuously seeking ways in which systems can be exploited to improve resilience, become more efficient and reduce costs. One way in which organisations seek to achieve this is by concentrating their efforts on core business processes and outsourcing non-core functions. However, outsourcing - and particularly offshoring - presents many security issues that must be considered throughout the lifetime of contracts. The scale of outsourcing and increasing technological and security complexity is making this task more difficult. Often …
Network Security – Is Ip Telephony Helping The Cause?, Paul Hansen, Andrew Woodward
Network Security – Is Ip Telephony Helping The Cause?, Paul Hansen, Andrew Woodward
Australian Information Security Management Conference
The major players in the Public Branch Exchange (PBX) market are moving rapidly towards the implementation of IP Telephony. What will be the effect on network security overall? Will the push to IP Telephony damage the good work already devoted to security networks? As more doorways open up on our networks there is an increased chance we have opened another unseen vector for hackers and other malicious organisation or individuals to access the data stored on server and users workstations, corrupting that data or destroying it. Is it better from a security perspective to have IP telephony only between PBX …
The Need For An Investigation Into Possible Security Threats Associated With Sql Based Emr Software, Lee Heinke
The Need For An Investigation Into Possible Security Threats Associated With Sql Based Emr Software, Lee Heinke
Australian Information Security Management Conference
An increasing amount of E-health software packages are being bundled with Standard Query Language (SQL) databases as a means of storing Electronic Medical Records (EMR’s). These databases allow medical practitioners to store, change and maintain large volumes of patient information. The software that utilizes these databases pulls data directly from fields within the database based on standardized query statements. These query statements use the same methods as web-based applications to dynamically pull data from the database so it can be manipulated by the Graphical User Interface (GUI). This paper proposes a study for an investigation into the susceptibility of popular …
Extensible Pre-Authentication In Kerberos, Phillip L. Hellewell
Extensible Pre-Authentication In Kerberos, Phillip L. Hellewell
Theses and Dissertations
Organizations need to provide services to a wide range of people, including strangers outside their local security domain. As the number of users grows larger, it becomes increasingly tedious to maintain and provision user accounts. It remains an open problem to create a system for provisioning outsiders that is secure, flexible, efficient, scalable, and easy to manage. Kerberos is a secure, industry-standard protocol. Currently, Kerberos operates as a closed system; all users must be specified upfront and managed on an individual basis. This paper presents EPAK (Extensible Pre-Authentication in Kerberos), a framework that enables Kerberos to operate as an open …
Oil. Changing Geopolitics Of Oil In Asia & The Usa, Jay Hein, John Clark, Robert Ebel, Dong Hyung Cha, Richard Lotspeich
Oil. Changing Geopolitics Of Oil In Asia & The Usa, Jay Hein, John Clark, Robert Ebel, Dong Hyung Cha, Richard Lotspeich
New England Journal of Public Policy
One of the most important responsibilities the United States assumed following World War II was ensuring the stable flow of relatively inexpensive oil to the industrialized and industrializing countries of the world. A glance at a list of the top petroleum exporting countries shows that most of them are poor, have despotic governments, and experience frequent bouts of political instability and ideological extremism.
Survey Of Supercomputer Cluster Security Issues, George Markowsky, Linda Markowsky
Survey Of Supercomputer Cluster Security Issues, George Markowsky, Linda Markowsky
Computer Science Faculty Research & Creative Works
The authors believe that providing security for supercomputer clusters is different from providing security for stand-alone PCs. The types of programs that supercomputer clusters run and the sort of data available on supercomputer clusters are fundamentally different from the programs and data found on stand-alone PCs. This situation might attract a different type of attacker with different goals and different tactics. This paper discusses the results of a questionnaire sent out to many supercomputer clusters in the United States and relates them to a literature search that was also undertaken. These results suggest approaches that can be taken to further …
Virtual Walls: Protecting Digital Privacy In Pervasive Environments, Apu Kapadia, Tristan Henderson, Jeffrey Fielding, David Kotz
Virtual Walls: Protecting Digital Privacy In Pervasive Environments, Apu Kapadia, Tristan Henderson, Jeffrey Fielding, David Kotz
Dartmouth Scholarship
As pervasive environments become more commonplace, the privacy of users is placed at an increased risk. The numerous and diverse sensors in these environments can record contextual information about users, leading to users unwittingly leaving “digital footprints.” Users must therefore be allowed to control how their digital footprints are reported to third parties. While a significant amount of prior work has focused on location privacy, location is only one specific type of footprint, and we expect most users to be incapable of specifying fine-grained policies for a multitude of footprints. In this paper we present a policy language based on …

The Benefits & Concerns Of Public Data Availability In Australia: A Survey Of Security Experts, Roba Abbas
The Benefits & Concerns Of Public Data Availability In Australia: A Survey Of Security Experts, Roba Abbas
Faculty of Informatics - Papers (Archive)
This paper gauges the attitudes of security experts in Australia with regards to public data availability on critical infrastructure protection (CIP). A qualitative survey was distributed to a individuals considered experts in CIP-related research in Australia, in order to address the censorship versus open access debate concerning public data. The intention of the study was to gain an insight into the perceived benefits and threats of public data availability by security experts, and to provide the basis for a security solution to be utilised by the Australian Government sector (at all levels). The findings however can also be applied to …

Modelling Mas-Specific Security Features, Ghassan Beydoun, Graham C. Low, Haralambos Mouratidis, Brian Henderson-Sellers
Faculty of Informatics - Papers (Archive)
In this paper, we pursue a modelling approach to address security requirements for multi-agent systems (MAS). This will allow developers to account for both the system and agent-specific security requirements of a MAS during the requirements phase and throughout the whole Software Development Lifecycle of the system. We focus on autonomy, mobility and cooperation of individual agents and how these create additional security vulnerabilities to the system. In proposing a set of generic modelling primitives for these engendered requirements in the analysis of the MAS, we extend our recently proposed MAS metamodel.

Rfid-Based Anti-Theft Auto Security System With An Immobilizer, Geeth Jayendra, Sisil Kumarawadu, Lasantha Meegahapola
Faculty of Informatics - Papers (Archive)
This paper presents a novel radio frequency identification (RFID) based vehicle immobilizer system, which features low hacking probability while preserving the safety of the passengers of the hijacked vehicle. The immobilizer uses the active RFID technology where the tag is generated with comparatively large character sets. The receiving unit is intelligently integrated into three control circuits in the vehicle, namely, ignition circuit, power control unit, and automatic gear changing system, enabling it to bring the vehicle speed down to zero in a safe step by step manner. The anti-theft auto security system proposed here was tested under different weather conditions …
Providing Vanet Security Through Active Position Detection, Gongjun Yan, Gyanesh Choudhary, Michele C. Weigle, Stephan Olariu
Providing Vanet Security Through Active Position Detection, Gongjun Yan, Gyanesh Choudhary, Michele C. Weigle, Stephan Olariu
Computer Science Faculty Publications
Our main contribution is a novel approach to enhancing position security in VANET. We achieve local and global position security by using the on-board radar to detect neighboring vehicles and to confirm their announced coordinates. We compute cosine similarity among data collected by radar and neighbors' reports to filter the forged data from the truthful data. Based on filtered data, we create a history of vehicle movement. By checking the history and computing similarity, we can prevent a large number of Sybil attacks and some combinations of Sybil and position-based attacks.

The focus of the paper is on the analysis of performance effects of different security solutions modeled as aspects in UML. Aspect oriented modeling (AOM) allows software designers to isolate and separately address solutions for crosscutting concerns, which are defined as distinct UML aspect models, then are composed with the primary UML model of the system under development. For performance analysis we use techniques developed previously in the PUMA project, which take as input UML models annotated with the standard UML Profile for Schedulability, Performance and Time (SPT), and transform them first into Core Scenario Model (CSM) and then into …
