Metrics and Methods for Security Risk Management

Security problems have evolved in the corporate world because of technological changes, such as using the Internet as a means of communication. With this, the creation, transmission, and storage of information may represent security problem.

Metrics and Methods for Security Risk Management is of interest, especially since the 9/11 terror attacks, because it addresses the ways to manage risk security in the corporate world. The book aims to provide information about the fundamentals of security risks and the corresponding components, an analytical approach to risk assessments and mitigation, and quantitative methods to assess the risk components. In addition, it also discusses the physical models, principles, and quantitative methods needed to assess the risk components. The by-products of the methodology used include security standards, audits, risk metrics, and program frameworks. Security professionals, as well as scientists and engineers who are working on technical issues related to security problems will find this book relevant and useful.

• Offers an integrated approach to assessing security risk
