1. Watching Smartly from the Bottom: Intrusion Detection revamped through Programmable Networks and Artificial Intelligence

Author

Subjects

Abstract

The advent of Programmable Data Planes represents an outstanding evolution and complete revolution of the Software- Defined Networking paradigm. The capacity to define the entire behavior of forwarding devices by controlling the packet parsing procedures and executing custom operations enables offloading functionalities traditionally performed at the control plane. A recent research line has explored the possibility of even offloading to the data plane part of Artificial Intelligence algorithms, and more specifically, Machine Learning ones, to increase their accuracy and responsiveness (by having more detailed visibility of the traffic). This introduces a significant opportunity for evolution in the critical field of Intrusion Detection. However, offloading functionalities to the data plane is not a straightforward task. In this paper, we discuss how Programmable Data Planes might complement different stages of an Intrusion Detection System based on Machine Learning. We present two use cases that make evident the feasibility of this approach and highlight aspects that must be considered when addressing the challenge of deploying solutions leveraging data-plane functionalities., Comment: 7 pages, 3 figures

2. ORACLE: Collaboration of Data and Control Planes to Detect DDoS Attacks

Abstract

The possibility of programming the control and data planes, enabled by the Software-Defined Networking (SDN) paradigm, represents a fertile ground on top of which novel operation and management mechanisms can be fully explored, being Distributed Denial of Service (DDoS) attack detection based on machine learning techniques the focus of this work. To carry out the detection, this paper proposes ORACLE: cOllaboRation of dAta and Control pLanEs to detect DDoS attacks, an architecture that promotes the coordination of control and data planes to detect network attacks. As its first contribution, this architecture delegates to the data plane the extraction and processing of traffic information collected per flow. This is done in order to ease the calculation and classification of the feature set used in the attack detection, as the needed flow information is already processed when it arrives at the control plane. Besides, as the second contribution, this architecture breaks the limitations to calculate some features that are not possible to implement in a traditional OpenFlow-based environment. In the evaluation of ORACLE, we obtained up to 96% of accuracy in the testing phase, using a K-Nearest Neighbor model., Comment: 6 pages, 5 figures, 5 tables, Submitted to IEEE ICC Conference

Abstract

National research and education networks (NRENs), such as ESnet, GéANT, and RNP, currently promote the employment of dynamic circuit networks (DCNs) to improve scientific communications beyond the capabilities of today's Internet. In spite of their alleged benefits to materialize user-initiated, ad hoc dedicated end-to-end circuits for high-demanding applications, DCNs also pose important challenges. Two examples are dealing with the end-user's lack of ability or willingness to understand low-level technicalities of virtual circuit establishment, and accommodating NRENs' local policies throughout the life-cycle of DCN. In this article, we seek to improve the usability of DCN services with a focus on the inexperienced end-user and the skilled network operator alike. We introduce MEICAN, a platform to manage the life-cycle of DCN from definition to provisioning of virtual circuits. We also present a case study of inter-domain circuit reservation with mixed manual and automated policy checking, and discuss lessons learned, relevant challenges, and open issues still to be overcome.

Abstract

Barcellos (b), Andre Detsch (b), Rodolfo S. Antunes (b) Keywords: Peer-to-peer; Security; Middleware Abstract: The widespread adoption of P2P applications in environments beyond ordinary file sharing demands the fulfillment of several security requirements. Important steps have been taken towards security in P2P systems, with relevant mechanisms being proposed in the past to address specific vulnerabilities. However, existing approaches lack flexibility, since they do not (include enough mechanisms to) tackle a wide range of requirements in an integrated fashion. In addition, they oblige the user/application to manipulate a complex programming interface, as well as going through a cumbersome configuration process. To address these issues, we present P2PSL (P2P Security Layer), a software architecture that allows gradual and flexible integration of security functionality into P2P applications. To show concept and technical feasibility, we have implemented P2PSL, assessed the overhead it induces, and estimated the feasibility of incorporating the layer into two categories of real world P2P applications.
