Being a novel P2P system, P2P E-commerce faces all network security issues as ordinary P2P systems do. One of the most severe threats is the imminent worm attacks aiming at P2P systems. Simple definition and taxonomy of P2P worm are presented and characteristics of different types of P2P worm are discussed. The possibility of using P2P system to contain P2P worm is explored, and preliminary countermeasures...
The 3 most important issues for anomaly detection based intrusion detection systems by using data mining methods are: feature selection, data value normalization, and the choice of data mining algorithms. In this paper, we study primarily the feature selection of network traffic and its impact on the detection rates. We use KDD CUP 1999 dataset as the sample for the study. We group the features of...
As digital resources increasingly growing and the economic benefit of digital intellectual property rights being increasingly important, people has been increasingly emphasis on information security issues brought by the data remnants in storage devices. They try their best to prevent the potential risks. In this paper, we survey comprehensively related technologies, standards and trends of erasure,...
For application researches of the detection for the gas signal source, a method for orientation estimation of the gas signal source in the two-dimensional space and its algorithm are presented in the paper. In the method, a mode of dual-line gas sensor array is applied to sample the signals of the gas concentration in real time, and the time delay estimation, an approach of the signal processing,...
Too often projects deliver software of which the quality is difficult to predict. Sometimes the project completion is delayed due to the continuous change of requirements while the software is still being built. The quality level must align with the company needs. It is extremely important that the planned benefits of an IT system are reached. When the benefits are not achieved it will cause much...
This position paper proposes a research agenda for the field of security testing. It gives a critical account of the state of the art as seen by a practitioner and identifies questions that research failed to answer so far, or failed to answer in such a way that it would have had an impact in the real world. Three categories of research problems are proposed: theory of vulnerabilities, theory of security...
The UNICORE grid system provides a seamless, secure and intuitive access to distributed grid resources. In recent years, UNICORE 5 is used as a well-tested grid middleware system in production grids (e.g. DEISA, D-Grid) and at many supercomputer centers world-wide. Beyond this production usage, UNICORE serves as a solid basis in many European and International research projects and business scenarios...
Compliance management (CM) is the management process that an organization implements to ensure organizational compliance with relevant requirements and expectations. Compliance auditing (CA) is a child-process of CM where compliance rules and policies are individually checked against the organization to determine the level of compliance achieved by the organization. In this paper, we arrange organizational...
Collecting data on user activities is one of the fundamental middleware services in Web-enabled systems. The collected data is analyzed and used by various high-level services, like user profiling, accounting, security auditing, and system health monitoring. In this paper, we present architecture and performance evaluation of usage tracking components for service-oriented middleware systems. Presented...
This is an introduction to the proceedings of the MWS 2007 workshop held at EDOC 2007. It first explains the motivation for and background of the workshop. Then, it contains a short description of the keynote, each long and short peer-reviewed paper, and the discussion session "impact of various execution environments on middleware for web services". After the closing statements, MWS 2007...
Requirements modeling has been recently introduced in the UML world with the form of a new profile called SysML. This paper explores the possibility to link concepts used to describe requirements with those of the enterprise language of RM-ODP. Some correspondence rules are proposed and illustrated on a case study.
The Open Distributed Processing Reference Model (ODP-RM) provides viewpoints and abstract infrastructure guidelines that can be used for a basis for enterprise architecture, especially for an inter-enterprise architecture. The ODP-RM does not prescribe methodology for modeling itself, but provides common vocabulary and focus for description. This paper performs a brief analysis of the ODP-RM (and...
Accelerated by the rapid deployment of distributed systems and the Internet, online collaboration and information sharing are pervasive in enterprise computing environment. With regard to the requirements of online collaboration and information sharing, authentication information needs flexible manipulation to facilitate federation across trust domains. To achieve identity federation for federated...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
In this paper we discuss the use cases for monitoring of Web services for compliance with policies and service level agreements. In particular, the quality of service associated with Web service interactions and its monitoring rely on the proper use by both parties of related Web service protocols. This monitoring is best served by an event-centric model and an extensible scripting language, such...
