Evaluation of Anomaly Detection techniques for SCADA communication resilience
Syed Noorulhassan Shirazi,Antonios Gouglidis,Kanza Noor Syeda,Steven Simpson,Andreas Mauthe,Ioannis M. Stephanakis,David Hutchison +6 more
TL;DR: Evaluated Anomaly Detection techniques indicate that detection rate may change significantly when considering various attack types and different detections modes, and provide indications that there is a need for a robust, and preferably real-time AD technique to introduce resilience in critical infrastructures.
Book ChapterDOI
Quality evaluation in peer-to-peer IPTV services
Mu Mu,William Knowles,Panagiotis Georgopoulos,Steven Simpson,Eduardo Cerqueira,Nicholas Race,Andreas Mauthe,David Hutchison +7 more
TL;DR: This work introduces an evaluation framework to assess video service with respect of user perception, while supporting service diagnosis to identify root-causes of any detected quality degradation.
Journal ArticleDOI
An Inter-Domain Collaboration Scheme to Remedy DDoS Attacks in Computer Networks
Steven Simpson,Syed Noorulhassan Shirazi,Angelos K. Marnerides,Simon Jouet,Dimitrios P. Pezaros,David Hutchison +5 more
TL;DR: A performance evaluation is presented to show that the core filtering mechanism of antidose is operationally feasible in the emerging trend of operators’ willingness to increase the programmability of their hardware with SDN technologies such as OpenFlow, as well as to act to mitigate attacks on downstream customers.
Proceedings ArticleDOI
Assessing the impact of intra-cloud live migration on anomaly detection
Noor-ul-hassan Shirazi,Steven Simpson,Angelos K. Marnerides,Michael Watson,Andreas Mauthe,David Hutchison +5 more
TL;DR: It is found that the performance for both detectors degrades as shown by their Receiver Operating Characteristics (ROC) curves when intra-cloud live migration is initiated while VMs are under a netscan (NS) or a denial-of-service (DoS) attack.
Journal ArticleDOI
Scalable adaptive hierarchical clustering
TL;DR: A new application-level clustering algorithm capable of building an overlay spanning tree among participants of large multicast sessions, without any specific help from the network routers is proposed.
