Future Forums are multiphase user centered design workshops, with the early phases aiming to initiate discussions, that then leads to the co-design of game elements centered around aspects of code security. The same procedure was followed for each of the three Future Forums, each focusing to a slightly different theme around cyber security. By engaging code-citizens in discussions on cyber security that are rooted in their personal experiences and individual viewpoints, several themes emerged, such as the role of coder practices and ethical behavior in security while coding. Findings gave us a deep insight in the code-citizens’ ecosystem during code development – both in terms of their individual beliefs and practices, and the practicalities they have to consider. Discussions were followed by the co-design and co-creation of game elements. The game elements code-citizens co-created allowed us to observe how code elements and code practices are represented with game elements, informing future designs of security oriented serious games. This paper discusses the implications these findings have to the design of cyber security oriented serious games, and to the wider HCI community working with similar methodologies.

System level provenance is of widespread interest for applications such as security enforcement and information protection. However, testing the correctness or completeness of provenance capture tools is challenging and currently done manually. In some cases there is not even a clear consensus about what behavior is correct. We present an automated tool, ProvMark, that uses an existing provenance system as a black box and reliably identifies the provenance graph structure recorded for a given activity, by a reduction to subgraph isomorphism problems handled by an external solver. ProvMark is a beginning step in the much needed area of testing and comparing the expressiveness of provenance systems. We demonstrate ProvMark's usefuless in comparing three capture systems with different architectures and distinct design philosophies.
