  • a brick wall a locked door and a bandit a physical security metaphor for Firewall warnings
    2011
    Co-Authors: Fahimeh Raja, Kirstie Hawkey, Steven Hsu, Kaile Clement Wang, Konstantin Beznosov
    Abstract:

    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.

  • revealing hidden context improving mental models of Personal Firewall users
    2009
    Co-Authors: Fahimeh Raja, Kirstie Hawkey, Konstantin Beznosov
    Abstract:

    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.

    Abstract:

    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.

  • Analysis and Design of Common Personal Firewall on Windows Platform
    2009
    Co-Authors: Gui Chao
    Abstract:

    The main functional attributes of Personal Firewall system are defined.The core technology for realizing is packets filtering.The Architecture of Window's Network(AWN) is presented,and on the basis of comparison between OSI and AWN,several solutions of packet filtering are listed.The solution using SPI is selected after reviewing and its key realization points to filter packets are offered.The Personal Firewall system realized using SPI shows good performance for filter network packets.

  • research on the Personal Firewall based on windows
    2010
    Co-Authors: Zhuang Weihua
    Abstract:

    A new method based on Windows kernel mode and user mode is proposed so as to solve the problems of packet capture in Personal Firewall products.The method is based on Windows Socket 2 SPI and NDIS HOOK.It avoids the defect of single way to capture packet.And theoretically,it can capture all the packets.Experimental results show that experimental system based on the new method of packet capture is effective and stable.
