Infrastructure Security Conference 2002 (InfraSec 2002) was created to promote security research and the development of practical solutions in the security of infrastructures – both government and commercial – such as the effective prevention of, detection of, reporting of, response to and recovery from security incidents. The conference, sponsored by the Datacard Group and Hewlett-Packard Laboratories, was held on October 1–3, 2002. Organizational support was provided by the Center for Cryptography, Computer and Network Security Center at the University of Wisconsin- Milwaukee. Organizing a conference is a major undertaking requiring the efforts of many individuals. The Conference President, Graham Higgins (Datacard Group), oversaw all arrangements for the conference, and the General Chair, Susan Thompson (Datacard Group), oversaw the local organization and registration. Local arrangements were directed by Jan Ward (Hewlett-Packard Laboratories) and Jamie Wilson (Datacard Group). Financial arrangements were managed by Natalie Churchill (Hewlett-Packard Laboratories). We wish to thank the organizers, without whose support this conference would not have been possible. This conference program included two keynote speakers: Bob Evans (Office of the e-Envoy) and Vic Maconachy (Department of Defense). The program committee considered 44 submissions of which 23 papers were accepted. Each submitted paper was reviewed by a minimum of three referees. These proceedings contain revised versions of the accepted papers. Revisions were not checked and the authors bear full responsibility for the content of their papers.
