Abstract
ISO27001 is a popular certification on Information Security Management System (ISMS). However, there are very few empirical studies investigating the market impact of ISO27001. In this research, we employed event study to analyze the financial impact of organizations after obtaining ISO 27001 certification in Taiwan. Among 456 certified organizations, we selected 23 public firms as samples and tested their stock price as well as ROA performance in both short-term and long-term. The results indicate that ISO27001 certification did not lead to significant abnormal performance. Hence, we argue that the necessity of certification should be reconsidered and future research can pay more attention on ISO27001 certification’s value in other dimensions and its contribution on internal improvement.
