Möbius is a multi-paradigm multi-solution framework to describe and analyze stochastic models of discrete-event dynamic systems. Möbius is widely used in academia and industry for the performance and dependability assessment of technical systems. It comes with a design of experiments as well as automated support for distributing a series of simulation experiments over a network to support the exploration of design spaces for real-world applications. In addition to that, the Möbius simulator interfaces with Traviando, a separate trace analyzer and visualizer that helps to investigate the details of a complex model for validation, verification, and debugging purposes. In this paper, we outline the development of a multi-formalism model of a Lustre-like file system, the analysis of its detailed simulated behavior, and the results obtained from a simulation study.

The ADversary VIew Security Evaluation (ADVISE) model formalism provides a system security model from the perspective of an adversary. An ADVISE atomic model consists of an attack execution graph (AEG) composed of attack steps, system state variables, and attack goals, as well as an adversary profile that defines the abilities and interests of a particular adversary. The ADVISE formalism has been implemented as a Möbius atomic model formalism in order to leverage the existing set of mature modeling formalisms and solution techniques offered by Möbius. This tool paper explains the ADVISE implementation in Möbius and provides technical details for Möbius users who want to use ADVISE either alone or in combination with other modeling formalisms provided by Möbius.
