1. 1. IT Dependability Management in Governmental Organisations

   Författare :Kim Weyns; Institutionen för datavetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dependability; IT management; Risk management; Information safety; Emergency management; Maturity models; Software reliability modelling; Service level agreements;

   Sammanfattning : As our dependence on IT systems increases, evaluating the dependability of critical IT systems becomes more important. This is especially true for systems that are critical in a crisis situation and whose dependability is an important factor in an organisation's capability to resolve a crisis. LÄS MER

3. 2. Dependability of IT Systems in Emergency Situations – Theory and Practice

   Författare :Kim Weyns; Institutionen för datavetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dependability; IT Systems; Emergency Management; Markov Models; Sensitivity Analysis; Swedish Municipalities;

   Sammanfattning : As our dependence on IT systems increases, evaluating the dependability of critical IT systems becomes more important. One of the main challenges in software reliability engineering is the sensitivity of software systems to a changing usage. LÄS MER

4. 3. 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

5. 4. Modeling and Tuning Security from a Quality of Service Perspective

   Författare :Stefan Lindskog; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; network security; quality of service QoS ; tunable security; dependability; security service; data protection; security evaluation; Datavetenskap; Computer Science;

   Sammanfattning : Security has traditionally been thought of as a system or network attribute that was the result of the joint endeavors of the designer, maintainer and user, among others. Even though security can never reach a level of 100%, the aim has been to provide as much security as possible, given the boundary conditions in question. With the advent of, e.g. LÄS MER

7. 5. Practical Experimentation as a Tool for Vulnerability Analysis and Security Evaluation

   Författare :Tomas Olovsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computers; dependability; vulnerabilities; tiger teams; taxonomy; operational security; analysis; security; terminology;

   Sammanfattning : The first part of this thesis describes the results of applying dependability methods to the security area. A uniform taxonomy for security, expected to contain all characteristic attributes, is presented. This taxonomy will hopefully increase the understanding of security issues. LÄS MER
