College Student Home Computer Security Adoption, Chet L. Claar, Robert C. Shields, David Rawlinson, Robert Lupton

All Faculty Scholarship for the College of the Sciences

The home Internet user faces a hostile environment abundant in potential attacks on their computers. These attacks have been increasing at an alarming rate and cause damage to individuals and organizations regularly, and have the potential to cripple the critical infrastructures of entire countries. Recent research has determined that some individuals are not utilizing additional software protections available to mitigate these potential security risks. This paper seeks to clarify the reasons by proposing a conceptual framework that utilizes the Health Belief Model as a possible way to explain why some people do not perceive a threat sufficient to prompt the …

A Simple Experiment With Microsoft Office 2010 And Windows 7 Utilizing Digital Forensic Methodology, Gregory H. Carlton

Journal of Digital Forensics, Security and Law

Digital forensic examiners are tasked with retrieving data from digital storage devices, and frequently these examiners are expected to explain the circumstances that led to the data being in its current state. Through written reports or verbal, expert testimony delivered in court, digital forensic examiners are expected to describe whether data have been altered, and if so, then to what extent have data been altered. Addressing these expectations results from opinions digital forensic examiners reach concerning their understanding of electronic storage and retrieval methods. The credibility of these opinions evolves from the scientific basis from which they are drawn using …

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 …

Notice And Consent In A World Of Big Data, Fred H. Cate, Viktor Mayer-Schönberger

Articles by Maurer Faculty

• Nowadays individuals are often presented with long and complex privacy notices routinely written by lawyers for lawyers, and are then requested to either ‘consent’ or abandon the use of the desired service.
• The over-use of notice and consent presents increasing challenges in an age of ‘Big Data’.
• These phenomena are receiving attention particularly in the context of the current review of the OECD Privacy Guidelines.
• In 2012 Microsoft sponsored an initiative designed to engage leading regulators, industry executives, public interest advocates, and academic experts in frank discussions about the role of individual control and notice and consent in data protection …

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 …

Measuring Inconsistency Methods For Evidentiary Value, Fred Cohen

Journal of Digital Forensics, Security and Law

Many inconsistency analysis methods may be used to detect altered records or statements. But for admission as evidence, the reliability of the method has to be determined and measured. For example, in China, for evidence to be admitted, it has to have 95% certainty of being correct,1 and that certainty must be shown to the court, while in the US, evidence is admitted if it is more probative than prejudicial (a >50% standard).2 In either case, it is necessary to provide a measurement of some sort in order to pass muster under challenges from the other side. And in most …

Technology Corner Visualising Forensic Data: Evidence (Part 1), Damian Schofield, Ken Fowle

Journal of Digital Forensics, Security and Law

Visualisation is becoming increasingly important for understanding information, such as investigative data (for example: computing, medical and crime scene evidence) and analysis (for example: network capability assessment, data file reconstruction and planning scenarios). Investigative data visualisation is used to reconstruct a scene or item and is used to assist the viewer (who may well be a member of the general public with little or no understanding of the subject matter) to understand what is being presented. Analysis visualisations, on the other hand, are usually developed to review data, information and assess competing scenario hypotheses for those who usually have an …

How Often Is Employee Anger An Insider Risk I? Detecting And Measuring Negative Sentiment Versus Insider Risk In Digital Communications, Eric Shaw, Maria Payri, Michael Cohn, Ilene R. Shaw

Journal of Digital Forensics, Security and Law

This research introduced two new scales for the identification and measurement of negative sentiment and insider risk in communications in order to examine the unexplored relationship between these two constructs. The inter-rater reliability and criterion validity of the Scale of Negativity in Texts (SNIT) and the Scale of Insider Risk in Digital Communications (SIRDC) were established with a random sample of email from the Enron archive and criterion measures from established insiders, disgruntled employees, suicidal, depressed, angry, anxious, and other sampled groups. In addition, the sensitivity of the scales to changes over time as the risk of digital attack increased …

How Often Is Employee Anger An Insider Risk Ii? Detecting And Measuring Negative Sentiment Versus Insider Risk In Digital Communications–Comparison Between Human Raters And Psycholinguistic Software, Eric Shaw, Maria Payri, Michael Cohn, Ilene R. Shaw

Journal of Digital Forensics, Security and Law

This research uses two recently introduced observer rating scales, (Shaw et al., 2013) for the identification and measurement of negative sentiment (the Scale for Negativity in Text or SNIT) and insider risk (Scale of Indicators of Risk in Digital Communication or SIRDC) in communications to test the performance of psycholinguistic software designed to detect indicators of these risk factors. The psycholinguistic software program, WarmTouch (WT), previously used for investigations, appeared to be an effective means for locating communications scored High or Medium in negative sentiment by the SNIT or High in insider risk by the SIRDC within a randomly selected …
