The International Workshop on Security in Information Systems is an annual event organized in conjunction with ICEIS conferences. The workshop is primarily focussed on high quality and innovative research papers from different fields related to the most recent developments in Information Systems Security. Traditionally the best papers are published in a reputable journal dealing with WOSIS topics. This year, authors will have the opportunity to have their work selected for publication in an extended version in the well recognized ISI ranked Publication Computer Standards and Interfaces journal. We would like to thank Professor Bhavani Thuraisingham, editor in Chief of CS&I for giving her support to this project from the beginning. The Computer Standards and Interfaces journal is concerned with the specification, development and application of standards and with highlevel publications of developments and methods in the areas of Standards, Information Management, Formal Methods;
Data Acquisition; Digital Instruments Standardization; Software Quality, Software Process; and Distributed Systems, Open Systems, and E-Topics. The last two areas are particularly close to WOSIS, including Information Systems, Distributed computing, Internet, Network security, Cryptology, E-services, Ebusiness, E-commerce, and so on. As standards are always present in many security areas such as Cryptographic protocols, web services and biometric security, etc and there are many people working in the development of security standards, this union has proved to be very productive. As a consequence, this year the review process has been particularly complex due to the excellent standard of the work submitted. Specifically, we have received a total of 35 submissions, a significant number of papers. All the submissions were reviewed by at least two program committee members or other experts in the field, although there were on average three reviewers for each paper. Finally, 16 papers have been accepted and 7 short papers will also have the chance to be presented during the sessions due to the excellent quality of the research. As usual, WOSIS 2007 will be held over two days in order for all the contributors to have time to hold talks and present their work. We would like to thank all the authors who took the time to submit papers to WOSIS, even though they were not finally accepted. Because of the high standard of the work submitted the review process was very difficult, and some good papers had to be rejected because of the sheer volume of work received. We would also to express our gratitude for the excellent work done by the Program Committee and the external reviewers. Special thanks to Dr. Ruth Breu who will honour us by offering the Keynote Speech which we hope you find motivating. The publication of the best papers in the prestigious Computer Standards and Interfaces Journal, along with the presence of a renowned Program Committee and Keynote Speaker, will contribute to the success of the 5th edition of WOSIS. We are indeed very happy that WOSIS has been well received and hope we can make progress in this direction in the future. Last but not least, on behalf of the Organizing and Program Committees we sincerely hope you enjoy the WOSIS technical program and the pleasant surroundings of Madeira during your free time. Looking forward to see you in WOSIS 2008!
