Differentially private transmission control protocol synchronise packet counts

Author: Mkuzangwe, Nenekazi NP ; Nelwamondo, Fulufhelo V Date: Sep 2019 Real Transmission Control Protocol synchronise (TCP SYN) packet counts availability will be of great benefit in anomaly detection. TCP SYN packet counts can beused for training intrusion detection system to detect a denial of service attack ... Read more
Ensemble of classifiers based network intrusion detection system performance bound

Author: Mkuzangwe, Nenekazi NP ; Nelwamondo, Fulufhelo V Date: Nov 2017 This paper provides a performance bound of a network intrusion detection system (NIDS) that uses an ensemble of classifiers. Currently researchers rely on implementing the ensemble of classifiers based NIDS before they can determine the ... Read more
A fuzzy logic based network intrusion detection system for predicting the TCP SYN flooding attack

Author: Mkuzangwe, Nenekazi NP ; Nelwamondo, Fulufhelo V Date: Apr 2017 Fuzzy logic is one of the powerful tools for reasoning under uncertainty and since uncertainty is an intrinsic characteristic of intrusion analysis, Fuzzy logic is therefore an appropriate tool to use to analyze intrusions in a Network. This ... Read more
Implementation of anomaly detection algorithms for detecting transmission control protocol synchronized flooding attacks

Author: Mkuzangwe, Nenekazi NP ; McDonald, Andre M ; Nelwamondo, Fulufhelo V Date: Aug 2015 This work implements two anomaly detection algorithms for detecting Transmission Control Protocol Synchronized (TCP SYN) flooding attack. The two algorithms are an adaptive threshold algorithm and a cumulative sum (CUSUM) based algorithm. ... Read more
