Games played within dynamic models have been explored in various domains, including cybersecurity and planning. Our paper introduces Obstruction Logic, a formalism designed for analyzing specific games featuring temporal objectives, which unfold within dynamic models. These games involve players whose actions can impact the underlying game model. We demonstrate how this logic can be employed to express significant properties within the realm of cybersecurity games, particularly those defined on attack graphs. An expanded version of our research has been published in ECAI 2023.
