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
Classification of Security Operation Centers

Author: Jacobs, P ; Arnab, A ; Irwin, B Date: Aug 2013 Security Operation Centers (SOCs) are a necessary service for organisations that want to address compliance and threat management. While there are frameworks in existence that addresses the technology aspects of these services, a holistic ... 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
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
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
Investigating multi-thread utilization as a software defence mechanism against side channel attacks

Author: Frieslaar, Ibraheem ; Irwin, B Date: Nov 2016 A state-of-the-art software countermeasure to defend against side channel attacks is investigated in this work. The implementation of this novel approach consists of using multithreads and a task scheduler on a microcontroller to purposefully ... Read more
An investigation into the signals leakage from a smartcard based on different runtime code

Author: Frieslaar, I ; Irwin, B Date: Sep 2015 This paper investigates the power leakage of a smartcard. It is intended to answer two vital questions: what information is leaked out when different characters are used as output; and does the length of the output affect the ... Read more
Mapping the most significant computer hacking events to a temporal computer attack model

Author: Van Heerden, Renier P ; Pieterse, Heloise ; Irwin, B Date: Sep 2012 This paper presents 8 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 presented ... Read more
Multi sensor national cyber security data fusion

Author: Swart, I ; Irwin, B ; Grobler, M Date: Mar 2015 A proliferation of cyber security strategies have recently been published around the world with as many as thirty five strategies documented since 2009. These published strategies indicate the growing need to obtain a clear view of a country’s ... Read more
A multi-threading approach to secure VERIFYPIN

Author: Frieslaar, Ibraheem ; Irwin, B Date: Oct 2016 This research investigates the use of a multi-threaded framework as a software countermeasure mechanism to prevent attacks on the verifypin process in a pin-acceptance program. The implementation comprises of using various mathematical ... Read more
An overview of Linux container based network emulation

Author: Peach, Schalk W ; Irwin, B ; Van Heerden, Renier P Date: Jul 2016 The objective of this paper is to assess the current state of Container-Based Emulator implementations on the Linux platform. Through a narrative overview, a selection of open source Container-Based emulators are analysed to collect information ... Read more
The pattern-richness of graphical passwords

Author: Vorster, JS ; Van Heerden, Renier P ; Irwin, B Date: Aug 2016 Conventional (text-based) passwords have shown patterns such as variations on the username, or known passwords such as ”password”, ”admin” or ”12345”. Patterns may similarly be detected in the use of Graphical passwords (GPs). The most ... Read more
Towards a platform to visualize the state of South Africa's information security

Author: Swart, I ; Irwin, B ; Grobler, M Date: Aug 2014 Attacks via the Internet infrastructure is increasingly becoming a daily occurrence and South Africa is no exception. In response, certain governments have published strategies pertaining to information security on a national level. These ... Read more
Towards a software approach to mitigate correlation power analysis

Author: Frieslaar, I ; Irwin, B Date: Jul 2016 In this research we present a novel implementation for a software countermeasure to mitigate Correlation Power Analysis (CPA). This countermeasure combines pseudo controlled-random dummy code and a task scheduler using multi threads to form ... Read more
Violations of good security practices in graphical passwords schemes: Enterprise constraints on scheme-design

Author: Vorster, J ; Irwin, B ; Van Heerden, Renier P Date: Mar 2018 During the past decade, the sophistication and maturity of Enterprise-level Information Security (EIS) Standards and Systems has increased significantly. This maturity, particularly in the handling of enterprise-wide capability models, has ... Read more
