  • A natural human language framework for digital forensic readiness in the public cloud 
    Baror, Stacey Omeleze; Venter, H.S. (Hein); Adeyemi, Richard (Taylor and Francis, 2021)
    Currently, about half of all global enterprises are adopting and using some form of cloud computing services. In cloud computing, potential digital evidence is distributed across multiple isolated virtual machine instances. ...
  • A near-miss management system architecture for the forensic investigation of software failures 
    Bella, M.A. Bihina; Eloff, Jan H.P. (Elsevier, 2016-02)
    Digital forensics has been proposed as a methodology for doing root-cause analysis of major software failures for quite a while. Despite this, similar software failures still occur repeatedly. A reason for this is the ...
  • Necessity for ethics in social engineering research 
    Mouton, Francois; Malan, Mercia M.; Kimppa, Kai K.; Venter, H.S. (Hein) (Elsevier, 2015-11)
    Social engineering is deeply entrenched in the fields of both computer science and social psychology. Knowledge is required in both these disciplines to perform social engineering based research. Several ethical concerns ...
  • Neural network crossover in genetic algorithms using genetic programming 
    Pretorius, Kyle; Pillay, Nelishia (Springer, 2024-06)
    The use of genetic algorithms (GAs) to evolve neural network (NN) weights has risen in popularity in recent years, particularly when used together with gradient descent as a mutation operator. However, crossover operators ...
  • Nonlinear regression in dynamic environments using particle swarm optimization 
    Kuranga, Cry; Pillay, Nelishia (Springer, 2020-11)
    This paper extends a PSO-based nonlinear regression technique to dynamic environments whereby the induced model dynamically adjusts when an environmental change is detected. As such, this work hybridizes a PSO designed for ...
  • NoSQL databases : forensic attribution implications 
    Hauger, W.K. (Werner); Olivier, Martin S. (South African Institute of Electrical Engineers, 2018-06)
    NoSQL databases have gained a lot of popularity over the last few years. They are now used in many new system implementations that work with vast amounts of data. Such data will typically also include sensitive information ...
  • A notation for sets, sequences and series : possible benefits for understanding and use 
    Du Plessis, Susanna H.; Pieterse, Vreda (Springer, 2017-11)
    The use of a well-designed and uniform notational system is imperative to improve communication and understanding. Currently, a fairly consistent notational system is used to notate the elements of sets, but the notations ...
  • The notion of 'aether': Hegel versus contemporary physics 
    Gruner, Stefan; Bartelmann, Matthias (Cosmos and History Publishing Co-op, 2015)
    Hegel's historically transient notion of 'aether', developed and finally abandoned again during his short period of time at the University of Jena in the early years of the 19th century, has received comparatively little ...
  • Novel digital forensic readiness technique in the cloud environment 
    Kebande, Victor Rigworo; Venter, H.S. (Hein) (Taylor and Francis, 2018)
    This paper examines the design and implementation of a feasible technique for performing Digital Forensic Readiness (DFR) in cloud computing environments. The approach employs a modified obfuscated Non-Malicious Botnet ...
  • A novel particle swarm niching technique based on extensive vector operations 
    Schoeman, I.L.; Engelbrecht, Andries P. (Springer, 2010-09)
    Several techniques have been proposed to extend the particle swarm optimization (PSO) paradigm so that multiple optima can be located and maintained within a convoluted search space. A significant number of these impl ...
  • Observing consistency in online communication patterns for user re-identification 
    Adeyemi, Ikuesan Richard; Razak, Shukor Abd; Salleh, Mazleena; Venter, H.S. (Hein) (Public Library of Science, 2016-12-05)
    Comprehension of the statistical and structural mechanisms governing human dynamics in online interaction plays a pivotal role in online user identification, online profile development, and recommender systems. However, ...
  • On compound purposes and compound reasons for enabling privacy 
    Van Staden, W.J.S. (Wynand Johannes Christiaan); Olivier, Martin S. (Graz University of Technology, 2011-02-01)
    This paper puts forward a verification method for compound purposes and compound reasons to be used during purpose limitation. When it is absolutely necessary to collect privacy related information, it is essential ...
  • On computer simulations, with particular regard to their application in contemporary astrophysics 
    Gruner, Stefan; Bartelmann, Matthias (Cosmos and History Publishing Co-op, 2020-10)
    In this survey contribution, which extends [GBa19], we consider and discuss computer simulations from a variety of perspectives with particular attention to computer simulations in astrophysics and cosmology. We begin by ...
  • On digital forensic readiness in the cloud using a distributed agent-based solution : issues and challenges 
    Kebande, Victor Rigworo; Venter, H.S. (Hein) (Taylor and Francis, 2018)
    The need to perform digital investigations has over the years led to the exponential growth of the field of Digital Forensics (DF). However, quite a number of challenges face the act of proving – for purposes of Digital ...
  • On more or less appropriate notions of ‘computation’ 
    Gravell, Andy M.; Gruner, Stefan (Computer Society of South Africa, 2018-07)
    Half a century after the emergence of computer science (a.k.a. informatics) as an academic discipline, the notion of ‘computation’ is not yet ‘settled’. On the contrary: recent developments in the natural sciences, in ...
