1. 1. 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
