The design and implementation of a local area network configurational audit tool

Configurational audit deals with identifying oversights or omissions in the use of otherwise secure computer security controls. Over the past decade, these errors, and the system vulnerability they create, have featured in many successful computer system attacks. Often, such vulnerability is easily introduced to systems, but difficult to manually detect. This thesis deals with configurational audit tools, which are used detect such vulnerability; an overview of technical vulnerability, as well as the field of configurational audit, are provided. A configurational audit and conformance tool called NetAudit is described. This tool, designed for the Novell NetWare 3.1x LAN operating system, uses conformance testing as its primary means of detecting vulnerability. The design and implementation of NetAudit are described, and the effectiveness of conformance testing as a means of performing configurational audit is assessed

Air Traffic Management Abbreviation Compendium

As in all fields of work, an unmanageable number of abbreviations are used today in aviation for terms, definitions, commands, standards and technical descriptions. This applies in general to the areas of aeronautical communication, navigation and surveillance, cockpit and air traffic control working positions, passenger and cargo transport, and all other areas of flight planning, organization and guidance. In addition, many abbreviations are used more than once or have different meanings in different languages. In order to obtain an overview of the most common abbreviations used in air traffic management, organizations like EUROCONTROL, FAA, DWD and DLR have published lists of abbreviations in the past, which have also been enclosed in this document. In addition, abbreviations from some larger international projects related to aviation have been included to provide users with a directory as complete as possible. This means that the second edition of the Air Traffic Management Abbreviation Compendium includes now around 16,500 abbreviations and acronyms from the field of aviation

An evaluation of the challenges of Multilingualism in Data Warehouse development

In this paper we discuss Business Intelligence and define what is meant by support for Multilingualism in a Business Intelligence reporting context. We identify support for Multilingualism as a challenging issue which has implications for data warehouse design and reporting performance. Data warehouses are a core component of most Business Intelligence systems and the star schema is the approach most widely used to develop data warehouses and dimensional Data Marts. We discuss the way in which Multilingualism can be supported in the Star Schema and identify that current approaches have serious limitations which include data redundancy and data manipulation, performance and maintenance issues. We propose a new approach to enable the optimal application of multilingualism in Business Intelligence. The proposed approach was found to produce satisfactory results when used in a proof-of-concept environment. Future work will include testing the approach in an enterprise environmen
