      Begnum, Miriam Eileen Nes; Finstadsveen, Johan; Begnum, Kyrre (The proceedings of Unitech : International Conference on Universal Technologies;2010, Chapter; Peer reviewed, 2010)
      Standard computer peripherals are often challenging to use for mobility impaired, and in particular controlling computer mouse movements efficiently and without risking strain injuries. Projected touch screen technology ...

    • Evading a Machine Learning-based Intrusion Detection System through Adversarial Perturbations 

      Fladby, Torgeir; Haugerud, Hårek; Nichele, Stefano; Begnum, Kyrre; Yazidi, Anis (RACS: Research in Applied Computation Symposium; RACS '20: International Conference on Research in Adaptive and Convergent Systems, Chapter; Peer reviewed; Conference proceeding, 2020-10)
      Machine-learning based Intrusion Detection and Prevention Systems provide significant value to organizations because they can efficiently detect previously unseen variations of known threats, new threats related to known ...

    • The Hydra: A layered, redundant configuration management approach for cloud-agnostic disaster recovery 

      Huang, Ke; Begnum, Kyrre (IEEE International Conference on Cloud Computing Technology and Science;, Chapter; Peer reviewed, 2013)
      This paper demonstrates a bottom-up approach to developing autonomic fault tolerance and disaster recovery on cloud-based deployments. We avoid lock-in to specific recovery features provided by the cloud itself, and instead ...

    • IncludeOS: A minimal, resource efficient unikernel for cloud services 

      Bratterud, Alfred; Walla, Alf-Andre; Haugerud, Hårek; Engelstad, Paal E.; Begnum, Kyrre (IEEE International Conference on Cloud Computing Technology and Science;2015, Journal article; Peer reviewed, 2015)
      The emergence of cloud computing as a ubiquitous platform for elastically scaling services has generated need and opportunity for new types of operating systems. A service that needs to be both elastic and resource efficient ...

    • On achieving intelligent traffic-aware consolidation of virtual machines in a data center using Learning Automata
