Proposta de dissertação do MEI Título: Secure Sketch-Based Monitoring for SDN-based Intrusion Detection Proponente(s): Henrique Domingos Créditos: 42 ECTS Área científica: Computer Systems and Networks Início preferencial: Qualquer semestre URL: Já estão em curso trabalhos preliminares executados pelo alunos: Breve descrição: The accuracy provided by conventional sampling-based monitoring approaches, such as Cisco NetFlow and other solutions, is increasingly being considered insufficient to meet the requirements of today’s networks in modern data-centers. By summarizing all traffic for specific statistics of interest, alternative sketch-based approaches have been shown to achieve higher levels of accuracy for the same cost, being particularly interesting for SDNs (Software Defines Networks) and the new generation of its internetworking devices. Existing switches lack the necessary capability and flexibility to perform the sort of processing required by this approach. However, the emergence of programmable SDN switches and the processing they enable in the data plane has recently led sketch-based solutions to be possible in switching hardware. One limitation of recent proposals is that they lack security and efficiency and this is the core objective of this dissertation. Observações:
