The 1st InternationalConference on Information Systems Security (ICISS 2005) was held December 19 21, 2005 at Jadavpur University, Kolkata, India. The objectives of the conference were to discuss in depth the current state of the research and practice in information systems security, enable participants to bene?tfrompersonalcontactwithotherresearchersandexpandtheirknowledge, and disseminate the research results. This volumecontains 4 invitedpapers,19refereedpapersthat werepresented at the conference, and 5 ongoing project summaries. The refereed papers, which were selected from the 72 submissions, were rigorouslyreviewed by the Program Committee members. The volume provides researcherswith a broad perspective of recent developments in information systems security. A special note of thanks goes to the many volunteers whose e?orts made this conference a success. We wish to thank Prem Chand, Ernesto Damiani, Patrick McDaniel, R. Sekar, and Vijay Varadharajan for agreeing to deliver the invited talks, the authors for their worthy contributions, and the referees for their time and e?ort in reviewing the papers. We are grateful to Arun Majumdar and Aditya Bagchi for serving as the General Chairs. Last, but certainly not least, our thanks go to Vijay Kowtha of the U.S. O?ce ofNaval ResearchGlobal and MichaelCheetham of the INDO-US Science & Technology Forum for providing the generous ?nancial support.
