Defending Against Insider Use Of Digital Steganography, James E. Wingate, Glenn D. Watt, Marc Kurtz, Chad W. Davis, Robert Lipscomb

Annual ADFSL Conference on Digital Forensics, Security and Law

The trusted insider is among the most harmful and difficult to detect threats to information security, according to the Federal Plan for Information Assurance and Cyber Security Research and Development released in April 2006. By default, employees become trusted insiders when granted the set of privileges needed to do their jobs, which typically includes access to the Internet. It is generally presumed the insiders are loyally working to achieve the organization’s goals and objectives and would not abuse the privileges given to them. However, some insiders will inevitably abuse some of their privileges. For example, a trusted insider might abuse …

Computer Geolocation Using Extracted Features, Chad M.S. Steel

Annual ADFSL Conference on Digital Forensics, Security and Law

This paper compares the extracted feature data from a sample set of hard drive images in an effort to relate the features to the physical location of the drive. A list of probable zip codes, phone numbers, place names, and IP addresses are extracted from raw drive images and compared to manually identified geolocation data. The results of the individual extractions are then analyzed to determine the feasibility in using automated extraction and analysis techniques for geolocating hard drives.

Education For Cyber Crime Investigators, David Greer, Joe Mulenex, John Hale, Gavin W. Manes

Annual ADFSL Conference on Digital Forensics, Security and Law

Digital forensics and cyber crime investigations are continually growing, rapidly changing fields requiring law enforcement agencies to meet very rigorous training requirements. New opportunities for committing criminal activity against persons, organization or property are presented every day with the proliferation of personal digital devices, computers, the internet, computer networks, and automated data systems. Whether the crime involves attacks against computer systems, electronic information, or more traditional crimes such as murder, money laundering or fraud, electronic evidence is becoming more prevalent. It is no surprise that law enforcement and criminal justice officials are being overwhelmed by the volume of investigations and …

Investigating Information Structure Of Phishing Emails Based On Persuasive Communication Perspective, Ki Jung Lee, Il-Yeol Song

Annual ADFSL Conference on Digital Forensics, Security and Law

Current approaches of phishing filters depend on classifying messages based on textually discernable features such as IP-based URLs or domain names as those features that can be easily extracted from a given phishing message. However, in the same sense, those easily perceptible features can be easily manipulated by sophisticated phishers. Therefore, it is important that universal patterns of phishing messages should be identified for feature extraction to serve as a basis for text classification. In this paper, we demonstrate that user perception regarding phishing message can be identified in central and peripheral routes of information processing. We also present a …

Towards Redaction Of Digital Information From Electronic Devices, Gavin W. Manes, Lance Watson, David Greer, Alex Barclay, John Hale

Annual ADFSL Conference on Digital Forensics, Security and Law

In the discovery portion of court proceedings, it is necessary to produce information to opposing counsel. Traditionally, this information is in paper form with all privileged information removed. Increasingly, the information requested during discovery exists in digital form and savvy counsel is requesting direct access to the original digital source: a broad spectrum of additional digital information can be often be extracted using digital forensics. This paper describes the major problems which must be solved to redact digital information from electronic devices. The primary hurdle facing digital redaction is the lack of a rational process for systematically handling encoded, encrypted, …

The Gap Between Theory And Practice In Digital Forensics, Joseph C. Sremack

Annual ADFSL Conference on Digital Forensics, Security and Law

Digital forensics is a young field that is being defined by the reactive nature of its development – in terms of both research and practice. As technology develops, digital forensics is forced to react and adapt. The rapid development of technology and the lack of an established theoretical foundation has led to a disconnect between the theory and practice of digital forensics. While the base theoretical issues are being worked on by researchers, practitioners are dealing with entirely new sets of issues. The complexity of investigations is increasing, and anti-forensics techniques are advancing as well. The disconnect will be resolved …

Teams Responsibilities For Digital Forensic Process, Salma Abdalla, Sherif Hazem, Sherif Hashem

Annual ADFSL Conference on Digital Forensics, Security and Law

This paper presents a detailed digital forensics process model and the responsible teams to perform it. The discussed model presents three teams and a forensic leader who coordinate between the three teams; these teams are physical crime scene team, laboratory examination team and courtroom team. These teams are responsible of achieving the digital forensic model by applying five main phases which are preparation phase, physical forensics and investigation phase, digital forensics phase, reporting and presentation phase and closure phase.

Most of the existing models in this field are either theoretical that deals with data processing or based on a legal …

New Federal Rules And Digital Evidence, Gavin W. Manes, Elizabeth Downing, Lance Watson, Christopher Thrutchley

Annual ADFSL Conference on Digital Forensics, Security and Law

The newly revised Federal Rules of Civil Procedure and developments under the Federal Rules of Evidence have a significant impact on the use, collection, and treatment of digital evidence for legal proceedings. The Rules now formally grant electronic documents and digital evidence the same status as paper and other forms of tangible evidence. As a result, the availability and proper preservation of potentially relevant electronic evidence must be considered, at the very latest, in the preliminary stages of litigation and, at the earliest, as soon as litigation is reasonably anticipated. It is important for professionals to be familiar with the …

Monitoring And Surveillance In The Workplace: Lessons Learnt? – Investigating The International Legal Position, Verine Etsebeth

Annual ADFSL Conference on Digital Forensics, Security and Law

When considering the legal implications of monitoring and surveillance in the workplace, the question may be asked why companies deploy computer surveillance and monitoring in the first place. Several reasons may be put forward to justify why more than 80% of all major American firms monitor employee e-mails and Internet usage. However, what most companies forget is the fact that the absence or presence of monitoring and surveillance activities in a company holds serious legal consequences for companies. From the discussion in this paper it will become apparent that there is a vast difference in how most countries approach this …

An Exploratory Analysis Of Computer Mediated Communications On Cyberstalking Severity, Stephen D. Barnes, David P. Biros

Annual ADFSL Conference on Digital Forensics, Security and Law

The interaction between disjunctive interpersonal relationships, those where the parties to the relationship disagree on the goals of the relationship, and the use of computer mediated communications channels is a relatively unexplored domain. Bargh (2002) suggests that CMC channels can amplify the development of interpersonal relationships, and notes that the effect is not constant across communications activities. This proposal suggests a line of research that explores the interaction between computer mediated communications (CMC) and stalking, which is a common form of disjunctive relationships. Field data from cyberstalking cases will be used to look at the effects of CMC channels on …

The General Digital Forensics Model, Steven Rigby, Marcus K. Rogers

Annual ADFSL Conference on Digital Forensics, Security and Law

The lack of a graphical representation of all of the principles, processes, and phases necessary to carry out an digital forensic investigation is a key inhibitor to effective education in this newly emerging field of study. Many digital forensic models have been suggested for this purpose but they lack explanatory power as they are merely a collection of lists or one-dimensional figures. This paper presents a new multi-dimensional model, the General Digital Forensics Model (GDFM), that shows the relationships and inter-connectedness of the principles and processes needed within the domain of digital forensics.

Keywords: process model, computer forensics, expert learning, …

Guideline Model For Digital Forensic Investigation, Salma Abdalla, Sherif Hazem, Sherif Hashem

Annual ADFSL Conference on Digital Forensics, Security and Law

This paper proposes a detailed guideline model for digital forensics; the proposed model consists of five main phases, Preparation phase, Physical Forensics and Investigation Phase, Digital Forensics Phase, Reporting and Presentation Phase, and Closure Phase.

Most of the existing models in this field do not cover all aspects of digital forensic investigations, as they focus mainly on the processing of digital evidence or on the legal points. Although they gave good information to base on it a guide, but they are not detailed enough to describe fully the investigative process in a way that can be used by investigators during …

The Evolution Of Internet Legal Regulation In Addressing Crime And Terrorism, Murdoch Watney

Annual ADFSL Conference on Digital Forensics, Security and Law

Internet regulation has evolved from self-regulation to the criminalization of conduct to state control of information available, accessed and submitted. Criticism has been leveled at the different forms of state control and the methods employed to enforce state control. After the terrorist attack on the USA on 11 September 2001, governments justify Internet state control as a law enforcement and national security tool against the abuse and misuse of the Internet for the commission of serious crimes, such as phishing, child pornography; terrorism and copyright infringement. Some Internet users and civil rights groups perceive state control as an abomination which …

Roundup Ready Alfalfa: Results After One Year On The Market, S. Ray Smith

Kentucky Alfalfa and Stored Forage Conference

Roundup Ready alfalfa has now been on the market for over a year with close to 30 varieties available or soon to be available across the U.S. This technology provides many new options for alfalfa producers in Kentucky. Several people have asked us which variety is highest yielding and unfortunately we have not been able to provide a good answer. The technology is so new (just approved fall 2005) that few of these varieties have been entered into University yield trials. Companies do have some private data, but they often don’t compare to the varieties you are familiar with. So …

Cowpea Aphids: Where Did They Come From, Will They Be Back?, Lee H. Townsend

Kentucky Alfalfa and Stored Forage Conference

Clearly, something was unusual back in March when large numbers of very dark aphids were found covering stems and tips in Logan, Marion, and Barren counties. They were the cowpea aphid or black legume aphid (Aphis craccivora), a sap-feeding insect known to occur in at least 28 states scattered over the US and into Canada. The cowpea aphid is the only black aphid found infesting alfalfa. Winged or wingless adults are usually shiny black, while the smaller nymphs are dull gray to black. Usually. they are lined along stems or clustered in the expanding leaf tips.

Hay Heating, Hay Sweat And Spontaneous Combustion, Tom Keene, Doug Overhults

Kentucky Alfalfa and Stored Forage Conference

Making hay in central Kentucky can be one of the most trying on farm endeavors a producer can undertake. Our plentiful moisture, rolling topography, and climate make Kentucky ideal for producing high quality forage for either grazing or hay making. However, that same moisture either in the form of rain or high humidity can sometimes make it devilishly hard to make quality hay here in Kentucky.

Alfalfa For Summer Grazing, John Johns

Kentucky Alfalfa and Stored Forage Conference

Alfalfa can make an excellent grazing forage for cattle in the summer as well as at other times of year provided that good grazing management is utilized. Alfalfa can be grazed very close to the ground but should not be grazed continuously. Initial regrowth after grazing comes from nutrient reserves in the root; therefore, a sufficient rest period or regrowth period without grazing must be allowed for these nutrients to be replenished. In summer, this rest period is 30 to 35 days. In adequate rest for root nutrient replenishment is not allowed, the plant will be weakened and stand life …

Alfalfa Hay For Horses, Robert Coleman

Kentucky Alfalfa and Stored Forage Conference

Horses are designed to eat forage and quality forage is the basis for the feeding programs of all classes of horse. However, when one considers hay as that basic forage, what criteria are used to describe quality horse hay? In general terms, quality horse hay should supply needed nutrients, be palatable and should be free of anything harmful to the horse.

Requirements For Successful Alfalfa Establishment, Garry D. Lacefield
