Bridging the gap between information security and strategic planning
This publication is a reflection of the author's firsthand experience as an information security consultant, working for an array of clients in the private and public sectors. Readers discover how to work with their organizations to develop and implement a successful information security plan by improving management practices and by establishing information security as an integral part of overall strategic planning.
The book starts with an overview of basic concepts in strategic planning, information technology strategy, and information security strategy. A practical guide to defining an information security strategy is then provided, covering the "nuts and bolts" of defining long-term information security goals that effectively protect information resources. Separate chapters covering technology strategy and management strategy clearly demonstrate that both are essential, complementary elements in protecting information.
Following this practical introduction to strategy development, subsequent chapters cover the theoretical foundation of an information security strategy, including:
* Examination of key enterprise planning models that correspond to different uses of information and different strategies for securing information
* Review of information economics, an essential link between information security strategy and business strategy
* Role of risk in building an information security strategy
Two separate case studies are developed, helping readers understand how the development and implementation of information security strategies can work within their own organizations.
This is essential reading for information security managers, information technology executives, and consultants. By linking information security to general management strategy, the publication is also recommended for nontechnical executives who need to protect the value and security of their organization's information.
