Abstract

Since the beginnings of time, human beings have displayed a strong need for safety and security. As a matter of course, this need has been oriented towards the specific situations of the time. In the 19^th and 20^th centuries, the so-called “industrial age”, this safety and security need was displayed in physical security measures, including measures and equipment to protect factory workers. Helmet and gloves remain essential parts of workers clothing on every building site. With the development of electronic data processing and the internet our society is moving rapidly into the “information age”. Modern information and communication technology allows data to be collected, saved, transmitted, and used in numerous ways. This development has led to an outstanding growth of processed information and produces new central resource - raw material information. Some of this information is freely accessible, some not. Information systems (IS) security demands that information is kept confidential and that the dependability of processing information systems is guaranteed.
