2015-11-16: What were the most important design choices in the development of the CORAS language? Check out the paper The CORAS Language - Why it is designed the way it is.

2015-09-03: A book focusing on risk management and assessment with respect to cybersecurity is now available: A. Refsdal, B. Solhaug and K. Stølen: Cyber-Risk Management. Springer, 2015. See Springer page.

2014-12-19: A new version (v1.4) of the Eclipse-based CORAS tool is now released. It is available for both the 32-bit and the 64-bit versions of Windows and Java, as well as for other major platforms such as Mac and Linux. See downloads.

2014-10-23: Existing standards and established methods and techniques provide little or no support for how to handle the complexity of large systems. Novel techniques for compositional risk modeling using CORAS is presented in a recent paper.

2013-12-28 A new version of the formal semantics for the CORAS modeling language is now available. Whereas the previous semantics was based on probabilities and probability reasoning, the new version supports reasoning about likelihoods using frequencies and frequency intervals. In the practical setting of risk modeling and analysis, frequencies are more adequate and suitable than probabilities. The new semantics can be found in the appendix of a technical report.

2012-10-08 For an introduction to CORAS, Chapter 3 of the CORAS book (A Guided Tour of the CORAS Method) can be downloaded for free from Springer. See also the product flyer for information about the book.
