We are now at the beginning of the new phase of global economic development called new economy. The bearers of it are especially information technologies, biotechnology, material, energetic and cosmic technologies. There is reflected the influence of important integration factors as new technologies, high competitiveness (which becomes a necessity), new economic culture in the sphere of government, households and business.

Case studies are used to describe good practices. Cases studies are coded structurally using a set of indicators for each success factor and thus provide for learning of the potential users. Synthesis and generalization has been done on factors explaining motivations for introducing e-practices, the results firms seek to achieve and the benefits from the adoption of digital technologies.

The analysis and the concept description of long-term strategies for eGovernment and a long-term vision over 10 years for eGovernment are described. Activities performed by the government are analysed from the demand ("front office") and supply ("back office") point of view. Recommendations for long-term strategic decisions are based on three scenarios of the future European development till 2010: (1) "Prosperous and just Europe", (2) "Turbulent world", (3) "Recession and reorientation".

In this contribution, the short survey of the different techniques to gather raw data is given. The gain of the paper should consist in the manifestation of explicit limitation of usage this data for further utilization and deductions depending on the scaling type and validity problems during data gathering.

Brechlerová Author-Workplace-Name: Czech University of Agriculture, Prague, Czech Republic Title: Neural networks in intrusion detection systems Abstract: Security of an information system is its very important property, especially today, when computers are interconnected via internet. Because no system can be absolutely secure, the timely and accurate detection of intrusions is necessary. For this purpose, Intrusion Detection Systems (IDS) were designed. There are two basic models of IDS: misuse IDS and anomaly IDS. Misuse systems detect intrusions by looking for activity that corresponds to the known signatures of intrusions or vulnerabilities. Anomaly systems detect intrusions by searching for an abnormal system activity. Most IDS commercial tools are misuse systems with rule-based expert system structure. However, these techniques are less successful when attack characteristics vary from built-in signatures. Artificial neural networks offer the potential to resolve these problems. As far as anomaly systems are concerned, it is very difficult to build them, because it is difficult to define the normal and abnormal behaviour of a system. Also for building anomaly system, neural networks can be used, because they can learn to discriminate the normal and abnormal behaviour of a system from examples. Therefore, they offer a promising technique for building anomaly systems. This paper presents an overview of the applicability of neural networks in building intrusion systems and discusses advantages and drawbacks of neural network technology.

Vrana Author-Workplace-Name: Czech University of Agriculture, Prague, Czech Republic Title: How to approach the development of enterprise information system Abstract: Nowadays, many enterprises face the problem of implementing their enterprise information system in order to keep pace with their competition. It holds generally for all types of enterprises, as e.g. manufacturing, agricultural, trading, financial, transportation, educational, etc. This paper deals with the basic rules for building an information system of the enterprise, particularly of medium or large ones. The attention is focussed at the problems each enterprise must address before starting an IS project. These are mainly the enterprise information policy planning, project feasibility and forms of its management.
