   Sammanfattning : Among a wide variety of topics that are covered by Dynamic Security Assessment (DSA), maintaining synchronous operation and acceptable voltage profiles stand out. These two stability categories are mostly jeopardized in the seconds after a large contingency occurs. LÄS MER

4. 3. A framework and theory for cyber security assessments

   Författare :Teodor Sommestad; Mathias Ekstedt; Ruth Breu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cyber security; security assessment; vulnerability assessment; architecture modeling; enterprise architecture;

   Sammanfattning : Information technology (IT) is critical and valuable to our society. An important type of IT system is Supervisor Control And Data Acquisition (SCADA) systems. These systems are used to control and monitor physical industrial processes like electrical power supply, water supply and railroad transport. LÄS MER

5. 4. Security in Physical Distribution Networks - A Survey Study of Swedish Transport Operators

   Författare :Luca Urciuoli; Teknisk logistik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antagonistic threats.; supply chain security; cargo security; physical distribution security; transportation security; cargo theft; Quantitative Risk Assessment;

   Sammanfattning : The objective of this study is to understand what factors influence the security of physical distribution networks. Thereafter it aims to bring to light what security measures exist today to enhance security and finally how to determine the profitability of security investments. LÄS MER

7. 5. Security in Physical Distribution - Causes, mitigation measures and an investment model

   Författare :Luca Urciuoli; Teknisk logistik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; security investments.; security measures in supply chains; causes of security vulnerability; antagonistic risks; security; physical distribution;

   Sammanfattning : Recent statistics and terror events testify an increased vulnerability of distribution networks. Antagonistic threats as theft, counterfeiting, contamination and terror are burdening supply chains with unexpected costs in form of lost cargo, production downtimes, lower customer satisfaction, and higher transportation costs.
