- W4210420904 abstract "Information technology system (ITS), informally, consists of hardware and software infrastructure (e.g., workstations, servers, laptops, installed software packages, databases, LANs, firewalls, etc.), along with physical and logical connections and inter-dependencies between various items. Nowadays, every company owns and operates an ITS, but detailed information about the system is rarely publicly available. However, there are many situations where the availability of such data would be beneficial. For example, cyber ranges need descriptions of complex realistic IT systems in order to provide an effective training and education platform. Furthermore, various algorithms in cybersecurity, in particular attack tree generation, need to be validated on realistic models of IT systems. In this paper, we describe a system we call the Generator that, based on the high-level requirements such as the number of employees and the business area the target company belongs to, generates a model of an ITS that satisfies the given requirements. We put special emphasis on the following two criteria: the generated ITS models a large amount of details, and ideally resembles a real system. Our survey of related literature found no sufficiently similar prior works, so we believe that this is the first attempt of building something like this. We created a proof-of-concept implementation of the Generator, validated it by generating ITS models for a simplified fictional financial institution, and analyzed the Generators performance with respect to the problem size. The research was done in an iterative manner, with coauthors continuously providing feedback on intermediate results. (...) We intend to extend this prototype to allow probabilistic generation of IT systems when only a subset of parameters is explicitly defined, and further develop and validate our approach with the help of domain experts." @default.
