Accurate Modeling Of The Siemens S7 Scada Protocol For Intrusion Detection And Digital Forensics, Amit Kleinmann, Avishai Wool
Journal of Digital Forensics, Security and Law
The Siemens S7 protocol is commonly used in SCADA systems for communications between a Human Machine Interface (HMI) and the Programmable Logic Controllers (PLCs). This paper presents a model-based Intrusion Detection Systems (IDS) designed for S7 networks. The approach is based on the key observation that S7 traffic to and from a specific PLC is highly periodic; as a result, each HMI-PLC channel can be modeled using its own unique Deterministic Finite Automaton (DFA). The resulting DFA-based IDS is very sensitive and is able to flag anomalies such as a message appearing out of its position in the normal sequence …

Personal Denial Of Service (Pdos) Attacks: A Discussion And Exploration Of A New Category Of Cyber Crime, Michael R. Bartolacci, Larry J. Leblanc, Ashley Podhradsky
Journal of Digital Forensics, Security and Law
The growth of the Internet has created a corresponding growth in Internet-based crimes and online misbehavior, particularly among younger computer-savvy people. Younger generations have grown up in a world where internet access, social networking, e-commerce and smartphones are commonplace. Given this fact, they have learned how to use, and how to abuse, technology. This leads us to define a new category of cybercrime called a Personal Denial of Service attack (PDOS). A PDOS is a cyber-crime in which an individual deliberately prevents the access of another individual or small group to online services such as email or banking. Due to …

File Detection On Network Traffic Using Approximate Matching, Frank Breitinger, Ibrahim Baggili
Journal of Digital Forensics, Security and Law
In recent years, Internet technologies changed enormously and allow faster Internet connections, higher data rates and mobile usage. Hence, it is possible to send huge amounts of data / files easily which is often used by insiders or attackers to steal intellectual property. As a consequence, data leakage prevention systems (DLPS) have been developed which analyze network traffic and alert in case of a data leak. Although the overall concepts of the detection techniques are known, the systems are mostly closed and commercial. Within this paper we present a new technique for network traffic analysis based on approximate matching (a.k.a …

Relating Admissibility Standards For Digital Evidence To Attack Scenario Reconstruction, Changwei Liu, Anoop Singhal, Duminda Wijesekera
Journal of Digital Forensics, Security and Law
Attackers tend to use complex techniques such as combining multi-step, multi-stage attack with anti-forensic tools to make it difficult to find incriminating evidence and reconstruct attack scenarios that can stand up to the expected level of evidence admissibility in a court of law. As a solution, we propose to integrate the legal aspects of evidence correlation into a Prolog based reasoner to address the admissibility requirements by creating most probable attack scenarios that satisfy admissibility standards for substantiating evidence. Using a prototype implementation, we show how evidence extracted by using forensic tools can be integrated with legal reasoning to reconstruct …

Audit: Automated Disk Investigation Toolkit, Umit Karabiyik, Sudhir Aggarwal
Journal of Digital Forensics, Security and Law
Software tools designed for disk analysis play a critical role today in forensics investigations. However, these digital forensics tools are often difficult to use, usually task specific, and generally require professionally trained users with IT backgrounds. The relevant tools are also often open source requiring additional technical knowledge and proper configuration. This makes it difficult for investigators without some computer science background to easily conduct the needed disk analysis. In this paper, we present AUDIT, a novel automated disk investigation toolkit that supports investigations conducted by non-expert (in IT and disk technology) and expert investigators. Our proof of concept design …

Evidentiary Power And Propriety Of Digital Identifiers And The Impact On Privacy Rights In The United States, Michael Losavio, Deborah Keeling
Journal of Digital Forensics, Security and Law
Media and network systems capture and store data about electronic activity in new, sometimes unprecedented ways; computational systems make for new means of analysis and knowledge development. These new forms offer new, powerful tactical tools for investigations of electronic malfeasance under traditional legal regulation of state power, particular that of Fourth Amendment limitations on police searches and seizures under the U.S. Constitution. But autonomy, identity and authenticity concerns with electronic data raise issues of public policy, privacy and proper police oversight of civil society. We examine those issues and their implications for digital and computational forensics

Effects Of The Factory Reset On Mobile Devices, Riqui Schwamm, Neil C. Rowe
Journal of Digital Forensics, Security and Law
Mobile devices usually provide a “factory-reset” tool to erase user-specific data from the main secondary storage. 9 Apple iPhones, 10 Android devices, and 2 BlackBerry devices were tested in the first systematic evaluation of the effectiveness of factory resets. Tests used the Cellebrite UME-36 Pro with the UFED Physical Analyzer, the Bulk Extractor open-source tool, and our own programs for extracting metadata, classifying file paths, and comparing them between images. Two phones were subjected to more detailed analysis. Results showed that many kinds of data were removed by the resets, but much user-specific configuration data was left. Android devices did …

Testing Framework For Mobile Device Forensics Tools, Maxwell Anobah, Shahzad Saleem, Oliver Popov
Journal of Digital Forensics, Security and Law
The proliferation of mobile communication and computing devices, in particular smart mobile phones, is almost paralleled with the increasing number of mobile device forensics tools in the market. Each mobile forensics tool vendor, on one hand claims to have a tool that is best in terms of performance, while on the other hand each tool vendor seems to be using different standards for testing their tools and thereby defining what support means differently. To overcome this problem, a testing framework based on a series of tests ranging from basic forensics tasks such as file system reconstruction up to more complex …

Technical Soddi Defenses: The Trojan Horse Defense Revisited, Chad M. Steel
Journal of Digital Forensics, Security and Law
In 2004, the Trojan horse defense was at a crossroads, having been successfully employed in two child pornography cases in the United Kingdom, resulting in acquittals. Despite the early successes, the Trojan horse defense has failed to become a regularly employed strategy. The original Trojan horse defense has now become part of the more general technical SODDI (Some Other Dude Did It) defense, which includes the possibility of unknown actors using unsecured Wi-Fi connections or having physical access to a computer to perform criminal acts. In the past ten years, it has not been effective in the United States for …

A State-Of-The-Art Review Of Cloud Forensics, Sameera Almulla, Youssef Iraqi, Andrew Jones
Journal of Digital Forensics, Security and Law
Cloud computing and digital forensics are emerging fields of technology. Unlike traditional digital forensics where the target environment can be almost completely isolated, acquired and can be under the investigators control; in cloud environments, the distribution of computation and storage poses unique and complex challenges to the investigators. Recently, the term “cloud forensics” has an increasing presence in the field of digital forensics. In this state-of-the-art review, we included the most recent research efforts that used “cloud forensics” as a keyword and then classify the literature into three dimensions: (1) survey-based, (2) technology-based and (3) forensics-procedural-based. We discuss widely accepted …

A Study Of Forensic Imaging In The Absence Of Write-Blockers, Gary C. Kessler, Gregory H. Carlton
Journal of Digital Forensics, Security and Law
Best practices in digital forensics demand the use of write-blockers when creating forensic images of digital media, and this has been a core tenet of computer forensics training for decades. The practice is so ingrained that the integrity of images created without a write-blocker are immediately suspect. This paper describes a research framework that compares forensic images acquired with and without utilizing write-blockers in order to understand the extent of the differences, if any, in the resultant forensic copies. We specifically address whether differences are superficial or evidentiary, and we discuss the impact of admitting evidence acquired without write blocking. …
