Securely erasing data is of key importance to anyone that is concerned with the security of their sensitive information, whether an individual or an organization. Simply deleting the data in question or formatting the storage device is not enough to ensure that the data cannot be recovered. Furthermore, with the uptake of Universal Serial Bus drives (USBs) flash memory based storage devices have replaced previous portable secondary storage media. Therefore, it is of a major concern whether these tools and products developed for securely erasing data secondary storage Hard Disk Drives (HDDs) would be as efficient when targeting the USB …
Security Analysis And Forensic Investigation Of Home & Commercial Alarm Systemsin New Zealand: Current Research Findings, Alastair Nisbet, Maria Kim
Security Analysis And Forensic Investigation Of Home & Commercial Alarm Systemsin New Zealand: Current Research Findings, Alastair Nisbet, Maria Kim
Australian Digital Forensics Conference
Alarm systems with keypads, sensors and sirens protect our homes and commercial premises from intruders. The reliability of these systems has improved over the past years but the technology has remained largely as it was 3 decades ago. With simple keypads and generally 4 digit PIN codes used for setting and unsetting the alarms, the main protection against a determined intruder is the necessity to choose robust PIN codes. However, with PIN codes chosen that are generally easy to remember and therefore relatively easy to guess, or numbers chosen to follow a pattern on the keypad, the main protection from …
A Forensic Comparison: Windows 7 And Windows 8, Peter J. Wilson
A Forensic Comparison: Windows 7 And Windows 8, Peter J. Wilson
Theses
Whenever a new operating system or new version of an operating system is released, forensic investigators must re-examine the new operating system or new version. They do so to determine if there are significant differences that will impact and change the way they perform their investigations. With the release of Microsoft's latest operating system, Windows 8, and its update, Windows 8.1, understanding the similarities and differences between Windows 8 and previous operating systems such as Windows 7 is critical. This paper forensically examines Windows 7 and Windows 8 to determine those similarities and differences.

Data Carving Parser Generation, Benjamin Nathaniel Kelley
Masters Theses, 2010-2019
As our day to day interaction with technology continues to grow, so does the amount of data created through this interaction. The science of digital forensics grew out of the need for specialists to recover, analyze, and interpret this data. When events or actions, either by accident or with criminal intent create, delete or manipulate data, it is the role of a digital forensics analyst to acquire this data and draw conclusions about the discovered facts about who or what is responsible for the event. This thesisidentifies a gap in the research between data analysis and interpretation. Current research and …
Distributed Digital Forensics On Pre-Existing Internal Networks, Jeremiah Jens Nielsen
Distributed Digital Forensics On Pre-Existing Internal Networks, Jeremiah Jens Nielsen
Open Access Theses
Today's large datasets are a major hindrance on digital investigations and have led to a substantial backlog of media that must be examined. While this media sits idle, its relevant investigation must sit idle inducing investigative time lag. This study created a client/server application architecture that operated on an existing pool of internally networked Windows 7 machines. This distributed digital forensic approach helps to address scalability concerns with other approaches while also being financially feasible. Text search runtimes and match counts were evaluated using several scenarios including a 100 GB image with prefabricated data. When compared to FTK 4.1, a …

Sellers Continue To Give Away Confidential Information On Second Hand Memory Cards Sold In Australia, Patryk Szewczyk, Nikki Robins, Krishnun Sansurooah
Australian Digital Forensics Conference
Second hand storage devices can be treasure troves of confidential data. This study investigated the remnant data on second hand memory cards that were purchased through Australian second hand auction websites throughout 2013. Memory cards continue to increase in capacity and are used in both smart phones and tablet computers as persistent storage. During this study a total of 140 second hand memory cards were purchased throughout 2013. Each memory card had its data recovered and subsequently analysed. The results show that sellers are sending memory cards with no evidence of erasure; poor attempts to erase data; or simply asking …
Information Security Challenge Of Qr Codes, Nik Thompson, Kevin Lee
Information Security Challenge Of Qr Codes, Nik Thompson, Kevin Lee
Journal of Digital Forensics, Security and Law
The discipline of information security must adapt to new technologies and methods of interaction with those technologies. New technologies present both challenges and opportunities for the security professional, especially for areas such as digital forensics. Challenges can be in the form of new devices such as smartphones or new methods of sharing information, such as social networks. One such rapidly emerging interaction technology is the use of Quick Response (QR) codes. These offer a physical mechanism for quick access to Web sites for advertising and social interaction. This paper argues that the common implementation of QR codes potentially presents security …

Analysis Of A Second Hand Google Mini Search Appliance, Stephen Larson
Journal of Digital Forensics, Security and Law
Information and the technological advancements for which mankind develops with regards to its storage has increased tremendously over the past few decades. As the total amount of data stored rapidly increases in conjunction with the amount of widely available computer-driven devices being used, solutions are being developed to better harness this data (LaTulippe, 2011). One of these solutions is commonly known as a search appliance. Search appliances have been used in e-discovery for several years. The Google Mini Search Appliance (Mini) has not only been used for e-discovery, but for indexing and searching internal documents. To accomplish these tasks, search …

The Advanced Data Acquisition Model (Adam): A Process Model For Digital Forensic Practice, Richard Adams, Val Hobbs, Graham Mann
Journal of Digital Forensics, Security and Law
As with other types of evidence, the courts make no presumption that digital evidence is reliable without some evidence of empirical testing in relation to the theories and techniques associated with its production. The issue of reliability means that courts pay close attention to the manner in which electronic evidence has been obtained and in particular the process in which the data is captured and stored. Previous process models have tended to focus on one particular area of digital forensic practice, such as law enforcement, and have not incorporated a formal description. We contend that this approach has prevented the …
