  1. 1. A Quantitative Approach to Computer Security from a Dependability Perspective

    Författare :Erland Jonsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intrusions; computers; modelling; vulnerability; dependability evaluation; experimentation; terminology; operational security; reliability; concepts; measures;

    Sammanfattning : Security and dependability represent two very important attributes of modern computer systems, especially in the light of the increasing complexity and criticality of these systems. These two disciplines have traditionally been treated separately, although lately some attempts have been made to integrate them. LÄS MER

  4. 3. Long-term cognitive outcome of childhood traumatic brain injury

    Författare :Catherine Aaro Jonsson; Ann-Charlotte Smedler; Ingrid Emanuelson; Erland Hjelmquist; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; traumatic brain injury; childhood; adolescence; neurosurgical care; cognitive development; executive functions; memory; verbal functions; long-term outcome; recovery; rehabilitation; follow-up; cluster analysis; Psychology; Psykologi; psykologi; Psychology;

    Sammanfattning : There is limited knowledge of cognitive outcome extending beyond 5 years after childhood traumatic brain injury, CTBI. The main objectives of this thesis were to investigate cognitive outcome at 6-14 years after CTBI, and to evaluate if advancements in the neurosurgical care, starting 1992, did influence long-term outcome and early epidemiology.

  5. 4. Adaptive Real-time Anomaly Detection for Safeguarding Critical Networks

    Författare :Kalle Ring Burbeck; Simin Nadjm-Tehrani; Erland Jonsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intrusion detection; anomaly detection; real-time; clustering; adaptation; IP networks; Computer science; Datalogi;

    Sammanfattning : Critical networks require defence in depth incorporating many different security technologies including intrusion detection. One important intrusion detection approach is called anomaly detection where normal (good) behaviour of users of the protected system is modelled, often using machine learning or data mining techniques.
