   Sammanfattning : Information technology (IT) systems are growing in complexity and are becoming more and more connected. Such connected systems can increase flexibility and productivity while also introducing security threats. LÄS MER

4. 3. Securing Judgement : Rethinking Security and Online Information Threats

   Författare :Hedvig Ördén; Hans Agné; Sharon Rider; Stefan Borg; Magnus Ekengren; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; security studies; critical security studies; cyber security; disinformation; Arendt; post-foundationalism; political theory; EU security policy; Political Science; statsvetenskap;

   Sammanfattning : The contemporary debate in democracies routinely describes online information threats such as misinformation, disinformation and deception as security-issues in need of urgent attention. Despite this pervasive discourse, policymakers often appear incapable of articulating what security means in this context. LÄS MER

5. 4. Tool Support for Enterprise Architecture Analysis : with application in cyber security

   Författare :Markus Buschle; Pontus Johnson; Stephan Aier; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Enterprise Architecture; Decision-making; Model-based analysis; Property analysis; Cyber security; Software tool; Design Science; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : In today’s companies, business processes and information technology areinterwoven. Old and new systems as well as off-the-shelf products and tailoredsolutions are used. This results in heterogeneous, often complex ITlandscapes. The impact of changes and the affected systems are difficult toidentify. LÄS MER

7. 5. 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
