      Abed, Amr S.; Clancy, Charles; Levy, David S. (Springer, 2015-12-09)
      Linux containers are gaining increasing traction in both individual and industrial use, and as these containers get integrated into mission-critical systems, real-time detection of malicious cyber attacks becomes a critical ...
    • Keystroke-Dynamics Authentication Against Synthetic Forgeries 

      Stefan, Deian; Yao, Danfeng (Daphne) (IEEE, 2010)
      We describe the use of keystroke-dynamics patterns for authentication and detecting infected hosts, and evaluate its robustness against forgery attacks. Specifically, we present a remote authentication framework called ...
    • LTE PHY Layer Vulnerability Analysis and Testing Using Open-Source SDR Tools 

      Rao, R. M.; Ha, S.; Marojevic, Vuk; Reed, J. H.
      This paper provides a methodology to study the PHY layer vulnerability of wireless protocols in hostile radio environments. Our approach is based on testing the vulnerabilities of a system by analyzing the individual ...
