The Cyber Risk group at SINTEF Digital focuses on industry-driven research and development within security risk assessment, cybersecurity, software quality, model-driven analysis and development, as well as empirical research on methods and tools.
Information and security technologies (ICT) have over several decades brought significant benefits to enterprises, individuals, and society as a whole. ICT and information infrastructures have become a cornerstone for a broad range of services that today we take for granted; people and organizations have access to more and better services than ever before within most areas of society, including banking and finance, communication, entertainment, health, power supply, social interactions, transportation and social participation. As a result, our daily lives, fundamental rights, economies and social security depend on ICT working seamlessly.
At the same time, ICT continues to introduce numerous new threats and vulnerabilities, and stakeholders are exposed to security incidents of many different kinds and degree of severity. Our research group develops methods, modelling techniques and tools to aid stakeholders in managing and assessing security risk, and in maintaining system and software security and quality. Our two books present major contributions in this respect.
- Atle Refsdal, Bjørnar Solhaug and Ketil Stølen: Cyber-Risk Management (Springer, 2015). The book can be ordered from Springer in printed version or electronically. See also the product flyer.
- Mass Soldal Lund, Bjørnar Solhaug and Ketil Stølen: Model-Driven Risk Analysis - The CORAS Approach (Springer, 2011). The book can be ordered from Springer in printed version or electronically. See also the product flyer.
Our cyber risk research is based on industry best practices and established international standards. Relevant standards include ISO 31000 on risk management, the ISO/IEC 27000 series on information security, as well as the OMG Unified Modeling Language (UML). Our main research interests are as follows:
- Security risk management
- Information security
- Model-driven risk analysis
- Model-driven security architecture
- Model-based quality assessment and prediction
- System modeling, refinement and semantics
- Tools for modeling, analysis and documentation
- Empirical research on methods and tools
- The CORAS approach to model-driven risk analysis. The approach includes a method, a modeling language and an open source tool. You may read the guided tour of the CORAS method for a quick introduction.
- The PREDIQT method resulting from the PhD thesis of Aida Omerovic.
- The STAIRS methodology developed in collaboration with the University of Oslo.
We have since more than ten years organized a series of public seminars where research results and new technologies are presented and discussed. The seminars are held in Norwegian and attract people from industry, public sector and academia.
- The next seminar is held on Tuesday April 4, 10:00-14:00, and addresses risk aggregation. The topic of the seminar is Risk Aggregation - What works in practise?
