Achieving Business Value in Information Security

Inhaltsangabe:Abstract: 
The beginning of the 21st century with the fear of the "Year 2000"-threat (Y2K) became a milestone for the "Information Age", a term coined for the post-industrial stage of leading countries „[…] when information and information technologies become the main strategic national resource which results in an avalanche growth of information dependence in all spheres of society and state activities.”. In organisations the awareness of the dependence on information has led to corporate initiatives to treat information as an asset, which includes various efforts for its protection. Management trends such as "knowledge management" have identified "knowledge sharing" as a new means for achieving competitive advantage, thus promoting information to be disseminated. Due to an ever closer relationship with customers, suppliers and even competitors, organisations have expanded their "information network" outside of the original boundaries.

Then again, although paying lip-service to treating information as an asset, top-management usually does not act upon it: the average InfoSec spending in the U.S. today is only 0.4 percent of an organisation’s revenue. 
In the following work it will be shown that a new approach to and a new understanding of InfoSec is vital for organisations to excel in the challenges faced by the information environment of the 21st century. The key focus of this study is to link existing InfoSec approaches to the concept of business value by ensuring their strategic fit with the corporate objectives. The first part will provide a common foundation with an evaluation of the role of information for organisations, relevant trends […]
