Automated classification of computer network attacks

Author: Van Heerden, Renier P ; Leenen, L ; Irwin, B Date: Nov 2013 In this paper we demonstrate how an automated reasoner, HermiT, is used to classify instances of computer network based attacks in conjunction with a network attack ontology. The ontology describes different types of network attacks through ... Read more

Classifying network attack scenarios using an ontology

Author: Van Heerden, Renier P ; Irwin, B ; Burke, Ivan D Date: Mar 2012 This paper presents eight of the most significant computer hacking events (also known as computer attacks). These events were selected because of their unique impact, methodology, or other properties. A temporal computer attack model is ... Read more
Classifying the Authenticity of Evaluated Smartphone Data

Author: Pieterse, Heloise ; Oliver, DM ; Van Heerden, Renier P Date: Aug 2019 Advances in smartphone technology coupled with the widespread use of such devices to accomplish daily tasks create valuable sources of smartphone data. Such data becomes increasingly important when smartphones are linked to civil or criminal ... Read more
Comparing models of offensive cyber operations

Author: Grant, T ; Burke, Ivan D ; Van Heerden, Renier P Date: Mar 2012 The purpose of this paper is to find, formalise, and compare models of the offensive cyber operations process available in the open scientific literature. Seven models were sufficiently well described for formalisation using Structured Analysis ... Read more
Comparing models of offensive cyber operations

Author: Grant, T ; Burke, Ivan D ; Van Heerden, Renier P Date: Oct 2015 Based on the idea that offensive cyber operations should be studied and merge from the darkness in which they typically hide, Grant and his colleagues embarked on a research program to explore the potential answers to the question, " What ...

A computer network attack taxonomy and ontology

Author: Van Heerden, Renier P ; Irwin, B ; Burke, Ivan D ; Leenen, L Date: 2012 Computer network attacks differ in the motivation of the entity behind the attack, the execution and the end result. The diversity of attacks has the consequence that no standard classification exists. The benefit of automated classification ... Read more

Developing a virtualised testbed environment in preparation for testing of network based attacks

Author: Van Heerden, Renier P ; Pieterse, Heloise ; Burke, Ivan D ; Irwin, B Date: Nov 2013 Computer network attacks are difficult to simulate due to the damage they may cause to live networks and the complexity required simulating a useful network. We constructed a virtualised network within a vSphere ESXi environment which is able ... Read more
Evaluating the authenticity of smartphone evidence

Author: Pieterse, Heloise ; Olivier, Marius ; Van Heerden, Renier P Date: Aug 2017 The widespread use and rich functionality of smartphones have made them valuable sources of digital evidence.

Graphical passwords: a qualitative study of password patterns

Author: Vorster, J ; Van Heerden, Renier P Date: Mar 2015 Graphical passwords schemas are becoming more main-stream. There are many different approaches to graphical passwords, each with its own drawbacks and advantages. There has been many studies to suggest that graphical passwords should be ... Read more
Heuristic attacks against graphical password generators

Author: Peach, S ; Vorster, J ; Van Heerden, Renier P Date: May 2010 In this paper the authors explore heuristic attacks against graphical password generators. A new trend is emerging to use user clickable pictures to generate passwords. This technique of authentication can be successfully used for - for example ... Read more
Human perception of the measurement of a network attack taxonomy in near real-time

Author: Van Heerden, Renier P ; Malan, MM ; Mouton, F ; Irwin, B Date: Jul 2014 This paper investigates how the measurement of a network attack taxonomy can be related to human perception. Network attacks do not have a time limitation, but the earlier its detected, the more damage can be prevented and the more ... Read more
Implementing honeypots as part of a simple cost effective wireless intrusion detection system

Author: Velupillai, HM ; Van Heerden, Renier P ; Vorster, J Date: Sep 2007 Wireless networks face innovative intrusion methods that have never been focused on wired networks.
