      Abouzakhar, Nasser; Bakar, Abu (2010-09-03)
      The rapid growth of Internet malicious activities has become a major concern to network forensics and security community. With the increasing use of IT technologies for managing information there is a need for stronger ...

    • Cloud Security : A Review of Recent Threats and Solution Models 

      Ugorji, Betrand; Abouzakhar, Nasser; Sapsford, John (Academic Conferences Ltd., 2013-10-18)
      The most significant barrier to the wide adoption of cloud services has been attributed to perceived cloud insecurity (Smitha, Anna and Dan, 2012). In an attempt to review this subject, this paper will explore some of the ...

    • A Comparative Study of Hidden Markov Model and Support Vector Machine in Anomaly Intrusion Detection 

      Jain, Ruchi; Abouzakhar, Nasser (2013-12)
      This paper aims to analyse the performance of Hidden Markov Model (HMM) and Support Vector Machine (SVM) for anomaly intrusion detection. These techniques discriminate between normal and abnormal behaviour of network ...

    • Critical Infrastructure Cybersecurity : A Review of Recent Threats and Violations 

      Abouzakhar, Nasser (2013-07-12)
      Most of current industries and their critical infrastructure rely heavily on the Internet for everything. The increase in the online services and operations for various industries has led to an increase in different security ...

    • Evaluation of Intelligent Intrusion Detection Models 

      Abouzakhar, Nasser; Manson, Gordon (2004)
      This paper discusses an evaluation methodology that can be used to assess the performance of intelligent techniques at detecting, as well as predicting, unauthorised activities in networks. The effectiveness and the ...

    • A Fingerprint Matching Model using Unsupervised Learning Approach 

      Abouzakhar, Nasser; Bello Abdulazeez, Muhammed (2009-09-01)
      The increase in the number of interconnected information systems and networks to the Internet has led to an increase in different security threats and violations such as unauthorised remote access. The existing network ...

    • Hidden Markov Model Based Anomaly Intrusion Detection 

      Jain, Ruchi; Abouzakhar, Nasser (2012)
      This paper aims to investigate and identify distinguishable TCP services, that comprise of both attack and normal types of TCP packets, using J48 decision tree algorithm. A predictive model capable of discriminating between ...

    • Information Security and Digital Forensics in the world of Cyber Physical Systems 

      Jones, Andrew; Vidalis, Stilianos; Abouzakhar, Nasser (Institute of Electrical and Electronics Engineers (IEEE), 2017-01-26)
      The security of Cyber Physical Systems and any digital forensic investigations into them will be highly dependent on data that is stored and processed in the Cloud. This paper looks at a number of the issues that will need ...
