Abstract

The goal of information security is to be able not just to put in place measures to detect and mitigate attacks but also to predict attacks, deter attackers from attacking, and thus defend the systems from attack in the first place. Data protection should be based on the lessons learned over time, both within the organization and in other organizations. Over the time, a large number of methodologies for identifying information security risks were proposed and adopted and simplified approach to different methodologies has led to their classification in quantitative and qualitative, especially in terms of metrics used to quantify risk. This chapter proposes an international overview regarding the quantitative and qualitative analysis methods for information risk analysis. In practice almost always use a combination of these methods, depending on the characteristics of the organization investigated the degree of uncertainty associated with the method of analysis and risk management.
