As the IEEE Transactions on Dependable and Secure Computing enters its fourth year, it is taking its place as a premier IEEE Computer Society transaction, with its value and impact being recognized in the peer community worldwide. Last year, we mapped out the challenges and new directions the journal would pursue. In the journal's fourth year, I see the transactions continuing to evolve and maintain its high profile in the dependability and security arenas. A brief overview of this issue's offerings shows the range and quality of this up-and-coming journal. Cai et al.'s "Wormshield: Fast Worm Signature Generation with Distributed Fingerprint Aggregation" presents both theoretical modeling and experimental results on a collaborative worm signature generation system that employs distributed fingerprint filtering and aggregation and multiple edge networks. "Modeling and Simulation Study of the Propagation and Defense of Internet E-mail Worm" by Zou et al. introduces an e-mail worm simulation model that accounts for the behaviors of e-mail users, including e-mail checking time and the probability of opening an e-mail attachment. "Fast Worm Containment Using Feedback Control" by Dantu et al. proposes a novel security architecture based on control system theory. Peisert et al. demonstrate the value of analyzing sequences of function calls for forensic analysis in "Analysis of Computer Intrusions Using Sequences of Function Calls." Reay et al. survey the adoption of the Platform for Privacy Preferences Protocol (PCP) on Internet Web sites to determine if P3P is a growing or stagnant technology in "A Survey and Analysis of the P3P Protocol's Agents, Adoption, Maintenance, and Future."
We have established yearly special issues based on the two major conferences in the Dependability and Security areas: the Conference on Dependable Systems and Networks and the Symposium on Security and Privacy. Future issues will include the publication of the second edition of each of these special issues. Given the status of TDSC at this time as a quarterly journal, we plan on keeping these special issues as we move forward, looking out for new opportunities for topical special issues.
A statistic of interest is that, during the past year, TDSC received a total of 185 manuscripts, up from 179 last year. In 2007, we have so far received 51 manuscripts. Last year, we published 29 papers in four issues.
This year we welcome new Associate Editors: Brian Randell, Lisa Spainhower, Doug Tygar, and Jeannette M. Wing. Each of them brings unique experience which adds to the ability of the editorial board to maintain the excellent quality of the journal. Completing their terms as Associate Editors are Mark Dacier, Jean-Claude Laprie, and Carl Landwehr. I would like to thank them for their outstanding service and dedication to this journal since its inception.
On this fourth anniversary, I wish to thank all of our 2006 associate editors, authors, and reviewers, each of whom makes the success of TDSC possible. I also wish to thank the wonderful publications staff at the IEEE Computer Society Publications office, in particular Suzanne Wagner and Joyce Arnold, whose support and dedication have helped us through our third year. Here at the University of Illinois, special thanks go to Heidi Leerkamp and Gerasimoula Kokkosis for providing exceptional support during this past year. Most importantly, my thanks go to the peer community at large—with your support TDSC goes forth into its fourth year with confidence and enthusiasm.
