Robust traffic classification with mislabelled training samples

Traffic classification plays the significant role in the network security and management. However, accurate classification is challenging if the training data is contaminated with unclean traffic. Recent researches often assume clean training data, and hence performance reduced on real-time network traffic. To meet this challenge, in this paper, we propose a robust method, Unclean Traffic Classification (UTC), which incorporates noise elimination and suspected noise reweighting. Firstly, UTC eliminates strong noisy training data identified by a consensus filtering with multiple classifiers. Furthermore, UTC estimates the relevance of remaining training data and learns a robust traffic classifier. Through a number of experiments on a real-world traffic dataset, we show that the new method outperforms existing state-of-the-art traffic classification methods, under the extremely difficult circumstance with unclean training data.

The longest conflict : Australia's climate security challenge

The Longest Conflict reveals our closest allies, the United States and United Kingdom, are taking climate security extremely seriously. Yet Australia’s defence establishment has not developed a strategic framework addressing climate security. Nor do we have a robust, whole of government plan for climate change.

National security, surveillance and terror: Canada and Australia in comparative perspective

This edited collection brings together leading scholars to comparatively investigate national security, surveillance and terror in the early 21st century in two major western jurisdictions, Canada and Australia. Observing that much debate about these topics is dominated by US and UK perspectives, the volume provides penetrating analysis of national security and surveillance practices in two under-studied countries that reveals critical insights into current trends. Written by a wide range of experts in their respective fields, this book addresses a fascinating array of timely questions about the relationship among national security, privacy and terror in the two countries and beyond. Chapters include critical assessments of topics such as: National Security Intelligence Collection since 9/11, The Border as Checkpoint in an Age of Hemispheric Security and Surveillance, Unmanned Aerial Vehicles and Law Enforcement, as well as Federal Government Departments and Security Regimes. An engaging and empirically driven study, this collection will be of great interest to scholars of security and surveillance studies, policing, and comparative criminology.
