Technology Corner: Virtual Crime Scene Reconstruction: The Basics Of 3d Modeling, Nick V. Flor

Journal of Digital Forensics, Security and Law

Digital crime scenes take place in the context of physical crime scenes. Virtual crime scene reconstruction is an activity where investigators create a 3- dimensional (3-D) model of an actual crime scene for the purpose of determining the events that lead to the crime. While virtual crime scene reconstruction is currently used for analyzing physical scenes, it can also help investigators visualize and explore ways digital media could have been used to perpetrate a crime. In this technology corner we explore one of the technologies underlying virtual crime scene reconstruction: 3-D modeling.

Designing A Knowledge Distribution Simulator, Martin Hill, Graham Fletcher Jan 2011

Designing A Knowledge Distribution Simulator, Martin Hill, Graham Fletcher

Australian Information Warfare and Security Conference

To make good decisions, we need to be suitably informed. 'Good' and 'Suitably' in this case depend on the informational needs of the decision and the mechanisms of getting the information to the decision maker in time. The trade-offs in qualities, quantities, timeliness, impacts on other activities, and so on are infamously wickedly complex, and usually buried in a clutter of special circumstances, personality characteristics, environments unsuitable for study, and so on. Decision-making systems can be explored using case studies and exercises, but these are limited by the expense and time of using real people. A virtual simulator for large …

A Risk Index Model For Security Incident Prioritisation, Nor Badrul Anuar, Steven Furnell, Maria Papadaki, Nathan Clarke Jan 2011

A Risk Index Model For Security Incident Prioritisation, Nor Badrul Anuar, Steven Furnell, Maria Papadaki, Nathan Clarke

Australian Information Security Management Conference

With thousands of incidents identified by security appliances every day, the process of distinguishing which incidents are important and which are trivial is complicated. This paper proposes an incident prioritisation model, the Risk Index Model (RIM), which is based on risk assessment and the Analytic Hierarchy Process (AHP). The model uses indicators, such as criticality, maintainability, replaceability, and dependability as decision factors to calculate incidents’ risk index. The RIM was validated using the MIT DARPA LLDOS 1.0 dataset, and the results were compared against the combined priorities of the Common Vulnerability Scoring System (CVSS) v2 and Snort Priority. The experimental …
