Intrusion detection systems (IDSs) have been substantially improved in recent past. However, network attacks have become more sophisticated and increasingly complex: many of current attacks are coordinated and originated in multiple networks. To detect these attacks, IDSs need to obtain information on network events from multiple networks or administrative domains. This work demonstrates that a Distributed IDS (DIDS) can be composed of existing IDSs, improving the detection of misuses in a multiple network environment. We use a grid middleware for creating a service-based intrusion detection grid. We demonstrate through experimental results that the proposed DIDS allows the integration of heterogeneous existing IDSs and improves the detection of attacks by exploring the synergy between existing IDSs.

Concepts and principles of TINA (Telecommunications Information networking Architecture) are introduced with the objective of correcting problems of centralized service control and service data model existent in INs (intelligent networks). Now, it is becoming clear that future sophisticated services breaking away from the simple telephony call model, e.g., multimedia, multi-party conferencing, etc., will need to be rapidly and efficiently introduced, deployed, operated and managed. In this context, TINA developed a comprehensive architecture for multi-service networks that will support multimedia services. On the other hand, the provisioning of all the service management functionality for TINA services (i.e. FCAPS) is still an open research question. In this paper, we discuss accounting features and requirements, security of accounting management, and issues for their integration in a TINA-based service environment. A prototype has been implemented to validate the concepts and results are also presented.

Ship design is often multidisciplinary involving several design elements with various types of objectives and constraints (O/C) some easily described as mathematical formulas, others better modeled as descriptive assertions. This paper describes a method based on fuzzy functions and an integrated performance index to model O/C using descriptive assertions to be used with mathematical formulas in optimization. Another issue addressed in this paper concerns the coordination of design elements when sequentially coupled, that is, when one leads the other and the performance of the follower depends greatly on the design of the leader. Based on neuro-fuzzy techniques, the method described here coordinates and optimizes sequentially coupled elements. The two methods are applied to machinery arrangement (MA) and pipe routing (PR). Preliminary models for optimization of MA and PR are described considering convenience, producibility: engine room size, interference and location as factors in the O/C set. Some test results from MA/PR applications are presented and discussed. The methods are generic and can be extended to other elements in ship design. They are mutually independent and may be used separately Two advantages of their use are an improvement in overall performance and a reduction in the need for redesign of elements.
