Improving Access Review with AuthzMap

AuthzMapResearch led by LERSSE Ph.D. student Pooya Jaferian will be featured at SOUPS this July. By interviewing IT professionals, he has explored access review activity in organizations, and then modeled access review in the activity theory framework. The model suggests that access review requires an understanding of the activity context including information about the users, their job, their access rights, and the history of access policy. Guidelines of the activity theory were used to design a new user interface, AuthzMap, which was compared to two state of the practice. The experiments demonstrated that AuthzMap improved the efficiency of access review most scenarios.

Project Presentations at Graduate Course in Security

Students in my graduate course on computer security are presenting their term papers on April 10. The topics vary from evaluation of Sybil detection mechanisms to detection of DDoS attacks on grid clusters. This mini-conference is open to public.

Heuristics for Evaluating IT Security Management Tools

The usability of IT security management (ITSM) tools is hard to evaluate by regular methods, making heuristic evaluation attractive. However, standard usability heuristics (e.g., Nielsen’s) are hard to apply, as IT security management occurs within a complex and collaborative context that involves diverse stakeholders. In a joint project with CA Technologies, my Ph.D. student Pooya Jaferian has proposed a set of ITSM usability heuristics that are based on activity theory, are supported by prior research, and consider the complex and cooperative nature of security management. The paper reporting the evaluation of the heuristics received Best Paper Award at SOUPS ’11.
