Unauthorized access from inside or outside an organization has become a social problem in the last few years, making a system that can detect such accesses desirable. We therefore monitor normal activities using inductive logic programming (ILP) which is one of machine learning and detect anomalies. To ensure effective monitoring, we think the following two points must be considered. One point is automation of detection by ILP system, which is a rule generation engine, that always induces and updates effective rules. The other point is providing a visualization tool that reflects induced rules to the detection system. This tool enables an administrator to understand detection situations. For automated detection, we provide the ILP system with an automatic parameter adjustment function. For the visualization tool, we apply the visualization technology of a hyperbolic tree.

Globalization, collaboration and competition are forcing product realization processes to become faster and more distributed. The requirements for higher efficiency, lower cost, and better product quality lead to challenges in the design of a product realization process in which concurrency and distribution are important. A distributed process structuring method (DPSM) is presented to help engineers design process architectures, based on characteristics of the distributed environment. DPSM also provides a framework for managing collaboration. With DPSM, a process is represented hierarchically by partitioning the process and reorganizing the activities. Four typical architecture templates, sequential, parallel, integrated and distributed architectures are presented. Process architectures are constructed by mapping the process representation into the templates. DPSM is a state-of-the-science method for structuring the distributed product realization process, while ensuring its modularity and robustness. An engineering case is investigated, and the distributed architecture is implemented using agent technology.

To collaborate in a 3D environment, update messages corresponding to the change in the state of a shared object must be communicated among users. While a lot of research has been done in terms of transmission of update messages representing the motion of avatars and objects, very few works focus on the collaboration itself. In this paper, we present an architecture that enables tightly-coupled collaborative tasks to be performed efficiently in virtual environments.

Workflow management systems focus on coordinating work that is situated in the real world. A strong trend towards combining workflow and Internet technologies has recently evolved. Workspaces combine coordination technology and standard Internet technology to exhibit various benefits of explicit procedure representation, distributed and uncoupled architecture and ease of access. Its architecture is based on workflows as coordinated transformations of documents. Basic steps transform XML documents under the control of an XSL (Extensible Stylesheet Language) engine. Coordination operations affect the order of execution in the workflow. Finally, a meta-step compiles a workflow graph represented in the XML-based Workspace Coordinated Language (WSCL) into a set of XSL rules for single transformation steps. Workspaces uses a Linda-like data space for coordination via XML documents.

The concept of Electronic Service Brokerage is based on the use of new information technologies to provide a service capable of facilitating and organizing the relationship between customers and offers providers. In this paper, a framework for Electronic Brokerage Service based on the emerging agent technology is presented. The first part of this article presents the requirements for electronic brokerage and the basic principles of the multi-agent used in Abrose. In the second part, we show the functionality of the Transaction Agents which represent the users inside the broke domain of Abrose. In the last part, we evaluate the dynamic properties of the user profile and belief network managed by each Transaction Agent. This electronic brokerage service will be applied in three business domains (Tourism, Trading and Teleworking). It covers the following features: the collaborative agents for self-organizing multi-agent systems, the multi-agents system for knowledge representation of the market place domain, the dynamic knowledge capture for a domain knowledge evolution.

The demand for the systems that facilitate human interactions over the World Wide Web is growing. Shared Place is a technology for building collaboration environments tightly integrated with the Web and customized for specific user needs. XML-based Shared Place Definition Language, designed to describe collaboration functionality of the configurable components, can be merged with ordinary Web page content to create specifications of virtual places. This paper discusses basic concepts of the Shared Placed technology, the model developed to describe functionality of virtual places, Shared Place documents and the architecture of the system. The discussion is illustrated with the examples of the applications.

We discuss a vision of a work in progress on a collaborative engineering environment, the Collaborative Design Studio, being developed at the Geometric and Intelligent Computing Laboratory at Drexel University. This works seeks to integrate Computer-Aided Design (CAD) and communication tools through automatic extraction and embedding of design contest into communications, as well as provide archiving and retrieval of informal communications. While preliminary development of the studio has proceeded using relatively informal input from professional design engineers, direct evaluation by intended users of the system will be sought to guide further developments of the system to ensure that it accurately meets their needs and fits into their work environment. Such formative user input will be obtained through surveys and observations of subjects as they complete specified tasks. Future summative evaluation will attempt to measure changes in user productivity and efficiency. Discussion focuses on issues and questions relating to the effective design and evaluation of such systems, and describe proposed studies for evolving the current environment.

This report summarizes the presentations of the 6th IEEE Enterprise Security Workshop. The workshop included twenty presentations, one invited talk and on discussion session. The presentations are divided into the following categories, representing a broad range of topics: Intrusion detection and system security; Access control, Anonymity, Environment and frameworks, Key recovery, Key management and protocols, Privacy and law. The invited talk was given by Distinguished Engineer of Sun Microsystems, Radia Perlman, on the topic of IPSec key exchange standards. A lively discussion session was organized by program co-chair Germano Carroni on the topic of future of firewall. In this report, we intend to highlight interesting and provocative topics that generated the most discussions in each session. We hope it serves as thought provoking questions that are seeking answers from the readers. In addition, we hope this summary report can be used to provide some additional information for the readers when reading the technical papers. The titles and authors of the presented papers are not repeated in the following summary. The reader is advised to refer to the presentation agenda which can be found at the WETICE 2001 website.

Explores some of the new opportunities for distributed collaborative applications that emerge from the use of XML as a data specification language. We present two different approaches: the first one transparently adds asynchronous collaboration to applications whose persistent state is in XML format, while the second one helps build synchronous collaborative applications starting with an XML schema specification. Although the two approaches start with different assumptions, they both lead to the same problem - the need for a generic one-to-one conversion between objects and XML constructs. Using object properties, we define two variants of a conversion scheme for the two approaches.
