Defining A Forensic Audit, G. S. Smith, D. L. Crumbley
Defining A Forensic Audit, G. S. Smith, D. L. Crumbley
Journal of Digital Forensics, Security and Law
Disclosures about new financial frauds and scandals are continually appearing in the press. As a consequence, the accounting profession's traditional methods of monitoring corporate financial activities are under intense scrutiny. At the same time, there is recognition that principles-based GAAP from the International Accounting Standards Board will become the recognized standard in the U.S. The authors argue that these two factors will change the practices used to fight corporate malfeasance as investigators adapt the techniques of accounting into a forensic audit engagement model.
Visualisation Of Honeypot Data Using Graphviz And Afterglow, Craig Valli
Visualisation Of Honeypot Data Using Graphviz And Afterglow, Craig Valli
Journal of Digital Forensics, Security and Law
This research in progress paper explores the use of Graphviz and Afterglow for the analysis of data emanating from a honeypot system. Honeypot systems gather a wide range of data that is often difficult to readily search for patterns and trends using conventional log file analysis techniques. The data from the honeypots has been statically extracted and processed through Afterglow scripts to produce inputs suitable for use by the DOT graph based tools contained within Graphviz. This paper explores some of the benefits and drawbacks of currently using this type of approach.
Information Overload: Cctv, Your Networks, Communities And Crime, Vandra Harris, Crispin Harris
Information Overload: Cctv, Your Networks, Communities And Crime, Vandra Harris, Crispin Harris
Australian Security and Intelligence Conference
Electronic surveillance continues to play a central but often unobserved role in contemporary Western societies and attempts to police them. This paper focuses on closed circuit television (CCTV) footage and its technological implications, particularly relating infrastructure and data storage and integrity. While CCTV might appear attractive in augmenting law enforcement systems, the authors argue that the debate on use of CCTV in crime prevention remains incomplete without an effective understanding of the diverse costs. This discussion reveals startling ICT resource needs and associated costs, together with very specific technological capacity. These contribute significantly to the costs of such systems, reinforcing …
Insecurity By Obscurity: A Review Of Soho Router Literature From A Network Security Perspective, Patryk Szewczyk, Craig Valli
Insecurity By Obscurity: A Review Of Soho Router Literature From A Network Security Perspective, Patryk Szewczyk, Craig Valli
Journal of Digital Forensics, Security and Law
Because of prevalent threats to SoHo based ADSL Routers, many more devices are compromised. Whilst an end-user may be at fault for not applying the appropriate security mechanisms to counter these threats, vendors should equally share the blame. This paper reveals that the lack of security related content and poor overall design could impact on end-users’ interpretation and willingness to implement security controls on their ADSL router. It argues that whilst the number of threats circulating the Internet is increasing, vendors are not improving their product literature.

Computer Science Faculty Publications
As detailed in Chap. 1, system implementations for dynamic taxonomies and faceted search allow a wide range of query possibilities on the data. Only when these are made accessible by appropriate user interfaces, the resulting applications can support a variety of search, browsing and analysis tasks. User interface design in this area is confronted with specific challenges. This chapter presents an overview of both established and novel principles and solutions.
Telecommunications Liberalisation In Africa: Proposed Regulatory Model For The Sadc Region, Z. N. Jobodwana
Telecommunications Liberalisation In Africa: Proposed Regulatory Model For The Sadc Region, Z. N. Jobodwana
Journal of Digital Forensics, Security and Law
The liberalisation of the telecommunication industry in Africa, and the further development of the region’s physical infrastructure was accompanied by the further development of Africa’s information, communication and technology infrastructure. Competition within the industry stimulated heavy economic investment in other sectors of the economy. The outcome of liberalisation also included the establishment of community-based structures that continue to enable communities to manage their own development and gain access to information and communication technologies (ICTs) in an unprecedented manner. The telecommunication infrastructure further stimulated the fast development of other related services, for example, ecommerce and mobile commerce (m-commerce), e-government, internet banking, …

Self-Reported Cyber Crime: An Analysis On The Effects Of Anonymity And Pre-Employment Integrity, Ibrahim Baggili, Marcus Rogers
Electrical & Computer Engineering and Computer Science Faculty Publications
A key issue facing today’s society is the increase in cyber crimes. Cyber crimes pose threats to nations, organizations and individuals across the globe. Much of the research in cyber crime has risen from computer science-centric programs, and little experimental research has been performed on the psychology of cyber crime. This has caused a knowledge gap in the study of cyber crime. To this end, this research focuses on understanding psychological concepts related to cyber crime. Through an experimental design, participants were randomly assigned to three groups with varying degrees of anonymity. After each treatment, participants were asked to self-report …
Special Set Linear Algebra And Special Set Fuzzy Linear Algebra, Florentin Smarandache, W.B. Vasantha Kandasamy, K. Ilanthenral
Special Set Linear Algebra And Special Set Fuzzy Linear Algebra, Florentin Smarandache, W.B. Vasantha Kandasamy, K. Ilanthenral
Branch Mathematics and Statistics Faculty and Staff Publications
This book for the first time introduces the notion of special set linear algebra and special set fuzzy linear algebra. This is an extension of the book set linear algebra and set fuzzy linear algebra. These algebraic structures basically exploit only the set theoretic property, hence in applications one can include a finite number of elements without affecting the systems property. These new structures are not only the most generalized structures but they can perform multi task simultaneously; hence they would be of immense use to computer scientists. This book has five chapters. In chapter one the basic concepts about …
Multiuser Private Queries Over Encrypted Databases, Yanjiang Yang, Feng Bao, Xuhua Ding, Robert H. Deng
Multiuser Private Queries Over Encrypted Databases, Yanjiang Yang, Feng Bao, Xuhua Ding, Robert H. Deng
Research Collection School Of Computing and Information Systems
Searchable encryption schemes allow users to perform keyword-based searches on an encrypted database. Almost all existing such schemes only consider the scenario where a single user acts as both the data owner and the querier. However, most databases in practice do not just serve one user; instead, they support search and write operations by multiple users. In this paper, we systematically study searchable encryption in a practical multiuser setting. Our results include a set of security notions for multiuser searchable encryption as well as a construction which is provably secure under the newly introduced security notions. We also discuss how …
A Comprehensive Study For Rfid Malwares On Mobile Devices, Qiang Yan, Yingjiu Li, Tieyan Li, Robert Huijie Deng
A Comprehensive Study For Rfid Malwares On Mobile Devices, Qiang Yan, Yingjiu Li, Tieyan Li, Robert Huijie Deng
Research Collection School Of Computing and Information Systems
Radio Frequency Identification (RFID) technique has been widely accepted as wireless identification standard in the business world. While RFID technique enables efficient collection of identification information, it also introduces new security risk due to the emerging of RFID malwares. This risk becomes increasingly severe due to the adoption of internet in RFID applications (e.g., track and trace in EPCglobal network) and the use of mobile devices as RFID readers. The prior work to defend the threat of RFID malwares has mainly focused on the protection of front-end tag-reader communications and back-end database systems. Less work has been conducted to defend …

Online Child Sexual Abuse: The French Response, Mohamed Chawki
Online Child Sexual Abuse: The French Response, Mohamed Chawki
Journal of Digital Forensics, Security and Law
Online child sexual abuse is an increasingly visible problem in society today. The introduction, growth and utilization of information and telecommunication technologies (ICTs) have been accompanied by an increase in illegal activities. With respect to cyberspace the Internet is an attractive environment to sex offenders. In addition to giving them greater access to minors, extending their reach from a limited geographical area to victims all around the world, it allows criminals to alter or conceal their identities. Sexual predators, stalkers, child pornographers and child traffickers can use various concealment techniques to make it more difficult for investigators to identify them …
Correlating Orphaned Windows Registry Data Structures, Damir Kahvedžić, Tahar Kechadi
Correlating Orphaned Windows Registry Data Structures, Damir Kahvedžić, Tahar Kechadi
Journal of Digital Forensics, Security and Law
Recently, it has been shown that deleted entries of the Microsoft Windows registry (keys) may still reside in the system files once the entries have been deleted from the active database. Investigating the complete keys in context may be extremely important from both a Forensic Investigation point of view and a legal point of view where a lack of context can bring doubt to an argument. In this paper we formalise the registry behaviour and show how a retrieved value may not maintain a relation to the part of the registry it belonged to and hence lose that context. We …

Continuous Fraud Detection In Enterprise Systems Through Audit Trail Analysis, Peter J. Best, Pall Rikhardsson, Mark Toleman
Continuous Fraud Detection In Enterprise Systems Through Audit Trail Analysis, Peter J. Best, Pall Rikhardsson, Mark Toleman
Journal of Digital Forensics, Security and Law
Enterprise systems, real time recording and real time reporting pose new and significant challenges to the accounting and auditing professions. This includes developing methods and tools for continuous assurance and fraud detection. In this paper we propose a methodology for continuous fraud detection that exploits security audit logs, changes in master records and accounting audit trails in enterprise systems. The steps in this process are: (1) threat monitoringsurveillance of security audit logs for ‘red flags’, (2) automated extraction and analysis of data from audit trails, and (3) using forensic investigation techniques to determine whether a fraud has actually occurred. We …

A Synopsis Of Proposed Data Protection Legislation In Sa, Francis S. Cronjé
Journal of Digital Forensics, Security and Law
Privacy International1 made the following statement regarding South Africa’s financial sector in its 2005 world survey: “South Africa has a well-developed financial system and banking infrastructure. Despite the sophistication of the financial sector, the privacy of financial information is weakly regulated by a code of conduct for banks issued by the Banking Council.” This extract highlights some of the problems South Africa are experiencing with its current status on privacy as viewed from an International perspective. In recent years the International society has stepped up its efforts in creating a global village wherein the individual could be assured of having …

Detection Of Steganography-Producing Software Artifacts On Crime-Related Seized Computers, Asawaree Kulkarni, James Goldman, Brad Nabholz, William Eyre
Detection Of Steganography-Producing Software Artifacts On Crime-Related Seized Computers, Asawaree Kulkarni, James Goldman, Brad Nabholz, William Eyre
Journal of Digital Forensics, Security and Law
Steganography is the art and science of hiding information within information so that an observer does not know that communication is taking place. Bad actors passing information using steganography are of concern to the national security establishment and law enforcement. An attempt was made to determine if steganography was being used by criminals to communicate information. Web crawling technology was used and images were downloaded from Web sites that were considered as likely candidates for containing information hidden using steganographic techniques. A detection tool was used to analyze these images. The research failed to demonstrate that steganography was prevalent on …

Prevention Is Better Than Prosecution: Deepening The Defence Against Cyber Crime, Jacqueline Fick
Prevention Is Better Than Prosecution: Deepening The Defence Against Cyber Crime, Jacqueline Fick
Journal of Digital Forensics, Security and Law
In the paper the author proposes that effectively and efficiently addressing cyber crime requires a shift in paradigm. For businesses and government departments alike the focus should be on prevention, rather than the prosecution of cyber criminals. The Defence in Depth strategy poses a practical solution for achieving Information Assurance in today’s highly networked environments. In a world where “absolute security” is an unachievable goal, the concept of Information Assurance poses significant benefits to securing one of an organization’s most valuable assets: Information. It will be argued that the approach of achieving Information Assurance within an organisation, coupled with the …
To License Or Not To License Revisited: An Examination Of State Statutes Regarding Private Investigators And Digital Examiners, Thomas Lonardo, Doug White, Alan Rea
To License Or Not To License Revisited: An Examination Of State Statutes Regarding Private Investigators And Digital Examiners, Thomas Lonardo, Doug White, Alan Rea
Journal of Digital Forensics, Security and Law
In this update to the previous year's study, the authors examine statutes that regulate, license, and enforce investigative functions in each US state. After identification and review of Private Investigator licensing requirements, the authors find that very few state statutes explicitly differentiate between Private Investigators and Digital Examiners. After contacting all state agencies the authors present a distinct grouping organizing state approaches to professional Digital Examiner licensing. The authors conclude that states must differentiate between Private Investigator and Digital Examiner licensing requirements and oversight.
The Impact Of Hard Disk Firmware Steganography On Computer Forensics, Iain Sutherland, Gareth Davies, Nick Pringle, Andrew Blyth
The Impact Of Hard Disk Firmware Steganography On Computer Forensics, Iain Sutherland, Gareth Davies, Nick Pringle, Andrew Blyth
Journal of Digital Forensics, Security and Law
The hard disk drive is probably the predominant form of storage media and is a primary data source in a forensic investigation. The majority of available software tools and literature relating to the investigation of the structure and content contained within a hard disk drive concerns the extraction and analysis of evidence from the various file systems which can reside in the user accessible area of the disk. It is known that there are other areas of the hard disk drive which could be used to conceal information, such as the Host Protected Area and the Device Configuration Overlay. There …

Electronic Forms-Based Computing For Evidentiary Analysis, Andy Luse, Brian Mennecke, Anthony M. Townsend
Journal of Digital Forensics, Security and Law
The paperwork associated with evidentiary collection and analysis is a highly repetitive and time-consuming process which often involves duplication of work and can frequently result in documentary errors. Electronic entry of evidencerelated information can facilitate greater accuracy and less time spent on data entry. This manuscript describes a general framework for the implementation of an electronic tablet-based system for evidentiary processing. This framework is then utilized in the design and implementation of an electronic tablet-based evidentiary input prototype system developed for use by forensic laboratories which serves as a verification of the proposed framework. The manuscript concludes with a discussion …
Graduate Accounting Students' Perception Of It Forensics: A Multi-Dimensional Analysis, Grover S. Kearns
Graduate Accounting Students' Perception Of It Forensics: A Multi-Dimensional Analysis, Grover S. Kearns
Journal of Digital Forensics, Security and Law
Forensics and information technology (IT) have become increasingly important to accountants and auditors. Undergraduate accounting students are introduced to general IT topics but discussion of forensic knowledge is limited. A few schools have introduced an undergraduate major in forensic accounting. Some graduate schools offer accounting students an emphasis in forensic or fraud accounting that includes instruction in forensics and information technology. When students do not view the IT topics as being equally important to their careers as traditional accounting topics, these attitudes may reduce the quality of the course. In an effort to assess student attitudes, a survey of 46 …

Critical infrastructures are the physical and virtual systems essential to the minimum operations of the economy and the government. Critical Infrastructure Protection (CIP) is a critical agenda item for governments in the developed countries. In these countries, policies and procedures on CIP are already in place and required laws are in action as well. In Turkey, some official introductory studies have been performed in 2009. However, there are a number of steps that Turkey still has to take. In this study, key definitions are provided firstly. After the definitions, the efforts of USA, EU, OECD and NATO are summarized. The …
Multicast Encryption Infrastructure For Security In Sensor Networks, Richard R. Brooks, Brijesh Pillai, Matthew Pirretti, Michele C. Weigle
Multicast Encryption Infrastructure For Security In Sensor Networks, Richard R. Brooks, Brijesh Pillai, Matthew Pirretti, Michele C. Weigle
Computer Science Faculty Publications
Designing secure sensor networks is difficult. We propose an approach that uses multicast communications and requires fewer encryptions than pairwise communications. The network is partitioned into multicast regions; each region is managed by a sensor node chosen to act as a keyserver. The keyservers solicit nodes in their neighborhood to join the local multicast tree. The keyserver generates a binary tree of keys to maintain communication within the multicast region using a shared key. Our approach supports a distributed key agreement protocol that identifies the compromised keys and supports membership changes with minimum system overhead. We evaluate the overhead of …
