Network security analysts presently lack tools for routinely screening large collections of network traffic for structures of interest. This is particularly the case when the structures of interest are embodied as summaries of sets of related traffic, essentially behaviour descriptions. This paper sketches a methodology to provide such capability, in the context of flow data. The methodology generates...
The intensive growth of processing power, data storage and transmission capabilities has revolutionized many aspects of science. These resources are essential to achieve high-quality results in many application areas. In this context, the University of Luxembourg (UL) operates since 2007 an High Performance Computing (HPC) facility and the related storage by a very small team. The aspect of bridging...
The cloud computing landscape has recently developed into a spectrum of cloud architectures, leading to a broad range of management tools for similar operations but specialized for certain deployment scenarios. This both hinders the efficient reuse of algorithmic innovations within cloud management operations and increases the heterogeneity between different management systems. Our overarching goal...
The process of packet filtering becomes time consuming as filtering policies become larger and more complex. New firewall designs are needed to meet the challenges associated with the high-speed networks. For this reason, access control lists in firewalls need to be flexible enough to give us the possibility to implement efficiently new high-performance filtering strategies. The precedence relationships...
