Exploring The Use Of Plc Debugging Tools For Digital Forensic Investigations On Scada Systems, Tina Wu, Jason R.C. Nurse Jan 2015

Exploring The Use Of Plc Debugging Tools For Digital Forensic Investigations On Scada Systems, Tina Wu, Jason R.C. Nurse

Journal of Digital Forensics, Security and Law

The Stuxnet malware attack has provided strong evidence for the development of a forensic capability to aid in thorough post-incident investigations. Current live forensic tools are typically used to acquire and examine memory from computers running either Windows or Unix. This makes them incompatible with embedded devices found on SCADA systems that have their own bespoke operating system. Currently, only a limited number of forensics tools have been developed for SCADA systems, with no development of tools to acquire the program code from PLCs. In this paper, we explore this problem with two main hypotheses in mind. Our first hypothesis …

Framing The Question, "Who Governs The Internet?", Robert J. Domanski Jan 2015

Framing The Question, "Who Governs The Internet?", Robert J. Domanski

Publications and Research

There remains a widespread perception among both the public and elements of academia that the Internet is “ungovernable”. However, this idea, as well as the notion that the Internet has become some type of cyber-libertarian utopia, is wholly inaccurate. Governments may certainly encounter tremendous difficulty in attempting to regulate the Internet, but numerous types of authority have nevertheless become pervasive. So who, then, governs the Internet? This book will contend that the Internet is, in fact, being governed, that it is being governed by specific and identifiable networks of policy actors, and that an argument can be made as to …

On Identities In Modern Networks, Libor Polcak, Radek Hranick, Tomas Martınek

Journal of Digital Forensics, Security and Law

Communicating parties inside computer networks use different kind of identifiers. Some of these identifiers are stable, e.g., logins used to access a specific service, some are only temporary, e.g., dynamically assigned IP addresses. This paper tackles several challenges of lawful interception that emerged in modern networks. The main contribution is the graph model that links identities learnt from various sources distributed in a network. The inferred identities result into an interception of more detailed data in conformance with the issued court order. The approach deals with network address translation, short-lived identifiers and simultaneous usage of different identities. The approach was …

An Efficient Similarity Digests Database Lookup – A Logarithmic Divide & Conquer Approach, Frank Breitinger, Christian Rathgeb, Harald Baier Jan 2014

An Efficient Similarity Digests Database Lookup – A Logarithmic Divide & Conquer Approach, Frank Breitinger, Christian Rathgeb, Harald Baier

Journal of Digital Forensics, Security and Law

Investigating seized devices within digital forensics represents a challenging task due to the increasing amount of data. Common procedures utilize automated file identification, which reduces the amount of data an investigator has to examine manually. In the past years the research field of approximate matching arises to detect similar data. However, if n denotes the number of similarity digests in a database, then the lookup for a single similarity digest is of complexity of O(n). This paper presents a concept to extend existing approximate matching algorithms, which reduces the lookup complexity from O(n) to O(log(n)). Our proposed approach is based …

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 …
