Abstract
Taiwan is a small island located in Far East of Asia, but its business organisations have the most market shares of supplying information technology hardware worldwide. Most local suppliers of these Taiwan-based high-tech companies are small or medium sized business. However, some companies in Taiwan are multi-national organisations with significant revenue and a large amount of suppliers. Therefore, Taiwan, as a new developed country, provides an ideal setting for us to explore various information system security threats encountered by their organisations and evaluate their achievement of security objectives and various counter measurements implemented by those organisations. The major purpose of this study is to provide some insight to the information systems security issues of e-business in Taiwan for researchers and practitioners.
