Raja, Fahimeh, Hawkey, Kirstie, Hsu, Steven, Wang, Kai-Le and Beznosov, Konstantin (2011): Promoting a physical security mental model for personal firewall warnings. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 1585-1590. Available online

We used an iterative process to design personal firewall warnings in which the functionality of a firewall is visualized based on a physical security mental model. We performed a study to determine the degree to which our proposed warnings are understandable for our participants, and the degree to which they convey the risks and encourage safe behavior as compared to warnings based on those from a popular personal firewall. Initial results show that our warnings facilitate the comprehension of warning information, better communicate risk, and increase the likelihood of safe behavior. Moreover, they provided participants with a better understanding of both the functionality of a personal firewall and the consequences of their actions.

We used an iterative process to design firewall warnings in which the functionality of a personal firewall is visualized based on a physical security metaphor. We performed a study to determine the degree to which our proposed warnings are understandable for users, and the degree to which they convey the risks and encourage safe behavior as compared to text warnings based on those from a popular personal firewall. The evaluation results show that our warnings facilitate the comprehension of warning information, better communicate the risk, and increase the likelihood of safe behavior. Moreover, they provide participants with a better understanding of both the functionality of a personal firewall and the consequences of their actions.

Raja, Fahimeh, Hawkey, Kirstie, Beznosov, Konstantin and Booth, Kellogg S. (2010): Investigating an appropriate design for personal firewalls. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 4123-4128. Available online

Personal firewalls are an important aspect of security for home computer users, but little attention has been given to their usability. We conducted semi-structured interviews to understand participants' knowledge, requirements, expectations, and misconceptions for personal firewalls. Analysis of 10 interviews shows that different design decisions (i.e., level of automation, multiple profile settings) are appropriate for users with different levels of security knowledge and experience.

Raja, Fahimeh, Hawkey, Kirstie and Beznosov, Konstantin (2009): Towards improving mental models of personal firewall users. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 4633-4638. Available online

Windows Vista's personal firewall provides its diverse users with a basic interface that hides many operational details. However, our study of this interface revealed that concealing the impact of network context on the security state of the firewall results in mental models that are unclear about the protection provided by the firewall resulting in an inaccurate understanding of the firewall configuration. We developed a prototype to support more contextually complete mental models through inclusion of network context information. Results from our initial evaluation of the prototype support our approach of improving user understanding of underlying system states by revealing hidden context, while considering the tension between complexity of the interface and security of the system.

The Windows Vista personal firewall provides its diverse users with a basic interface that hides many operational details. However, concealing the impact of network context on the security state of the firewall may result in users developing an incorrect mental model of the protection provided by the firewall. We present a study of participants' mental models of Vista Firewall (VF). We investigated changes to those mental models and their understanding of the firewall's settings after working with both the VF basic interface and our prototype. Our prototype was designed to support development of a more contextually complete mental model through inclusion of network location and connection information. We found that participants produced richer mental models after using the prototype than when working with the VF basic interface; they were also significantly more accurate in their understanding of the configuration of the firewall. Based on our results, we discuss methods of improving user understanding of underlying system states by revealing hidden context, while considering the tension between complexity of the interface and security of the system.

Jaferian, Pooya, Botta, David, Raja, Fahimeh, Hawkey, Kirstie and Beznosov, Konstantin (2008): Guidelines for designing IT security management tools. In: Proceedings of the 2008 Symposium on Computer Human Interaction for the Management of Information Technology 2008. p. 7. Available online

An important factor that impacts the effectiveness of security systems within an organization is the usability of security management tools. In this paper, we present a survey of design guidelines for such tools. We gathered guidelines and recommendations related to IT security management tools from the literature as well as from our own prior studies of IT security management. We categorized and combined these into a set of high level guidelines and identified the relationships between the guidelines and challenges in IT security management. We also illustrated the need for the guidelines, where possible, with quotes from additional interviews with five security practitioners. Our framework of guidelines can be used by those developing IT security tools, as well as by practitioners and managers evaluating tools.
