Knowledge Requirement

Architectural risk analysis is knowledge intensive. For example, Microsoft’s STRIDE model involves the understanding and application of several risk categories during analysis [4] [Howard and LeBlanc 2003]. Similarly, my risk analysis approach involves three basic steps (described more fully later in the chapter):

  1. Attack resistance analysis
  2. Ambiguity analysis
  3. Weakness analysis

Knowledge is most useful in each of these steps: the use of attack patterns [Hoglund and McGraw 2004] and exploit graphs for understanding attack resistance analysis, knowledge of design principles for use in ambiguity analysis [Viega and McGraw 2001], and knowledge regarding security issues in commonly used frameworks (.NET and J2EE being two examples) and other third-party components to perform weakness analysis. These three subprocesses of my approach to risk analysis are discussed in detail in this chapter.

For more on the kinds of knowledge useful to all aspects of software security, including architectural risk analysis, see Chapter 11.
