Abstract for the Call for Participants The human factor is often described as the weakest part of a security system and users are often described as the weakest link in the security chain. This workshop will seek to understand the roles and demands placed on users of security systems, and explore design solutions that can assist in making security systems usable and effective. In addition to examining end-users, this workshop will also examine the issues faced by security system developers and operators. The primary motivation for the workshop is that previous research on HCI and Security (HCISEC) has been scattered in different conferences and journals, and information sharing has been difficult. The goal of the workshop is to build a network of interested people, share research activities and results, discuss high priority areas for research and development, and explore opportunities for collaboration. Security is a large topic so there are many areas where HCI is important. Three obvious areas of interest are authentication (passwords, biometrics, etc.), security operations (intrusion detection, vigilance, policies and practices, etc.), and developing secure systems (developing for security, understanding users, installation and operation support, etc.). We are interested in receiving submissions on these topics, and suggestions of other possible topic areas are also welcome. Contributions should be in the CHI 2003 Extended Abstracts style, 2 to 4 pages long. Participants will be selected based on the contribution to the goals of the workshop, the shared interests of the other participants, and likelihood to promote discussion and collaboration.
