Most companies and government agencies rely on computer networks to store and manage their organizations' data; it is essential that measures are put in place to secure those networks and keep them functioning optimally. Network administrators need to define their security management systems to cover all parts of their computer and network resources. Organizations interested in implementing a comprehensive security management system should start by documenting all business processes that are critical to an organization and then analyzing the risks associated with them, then implement the controls that can protect those processes from external and internal threats. Internet threats are not usually the cause of someone with malicious intent but someone who accidentally downloads a Trojan or accidentally moves or deletes a directory or critical files. The final step is performing recursive checking of the policies the organization has put in place to adjust for new technologies that need to be protected or new ways that external threats can damage the network. The easiest way to implement security management systems is to use the Plan-Do-Act-Check process to step though the necessary procedures.

This document provides an update on the development of OntoSearch(1)(2), an ontology search engine designed to help users find RDF based ontological information on the Semantic Web. It uses the Google API to search several million documents on the Semantic Web and uses these results to populate a local repository of ontological data. This is then searched using queries optimised for the relation- ships within Ontologies. It supports various visualisation and representational algorithms. These facilities allow the user to make a rapid assessment of the files retrieved.

Chaosynth is a cellular automata-based granular synthesis system whose capabilities for producing unusual complex dynamic sounds are limitless. However, due to its newness and flexibility, potential users have found it very hard to explore its possibilities as there is no clear referential framework to hold on to when designing sounds. Standard software synthesis systems take this framework for granted by adopting a taxonomy for synthesis instruments that has been inherited from the acoustic musical instruments tradition, i.e. woodwind, brass, string, percussion, etc. Sadly, the most interesting synthesised sounds that these systems can produce are simply referred to as effects. This scheme clearly does not meet the demands of more innovative software synthesizers. In order to alleviate this problem, we propose an alternative taxonomy for Chaosynth timbres. The paper begins with a brief introduction to the basic functioning of Chaosynth. It then presents our proposed taxonomy and ends with concluding comments. A number of examples are provided on this volume's Organised Sound CD.
