Phase 1 – Requirements Discovery

The first task in the DE life cycle is to collect detection requirements. The Requirements Discovery phase can be initiated from multiple sources, as described here, and results in detection requirements, which will be passed onto the Triage phase for further evaluation. At a high level, we can analyze inputs and outputs for each phase. In this case, we have the following:

  • Input: Findings from detection requirement sources
  • Output: Detection requirement(s) with the details specified in the Characteristics of a complete detection requirement section

This section will outline various aspects of the Requirements Discovery phase, such as what a detection requirement should include and where those requirements come from. To start, we’ll examine the characteristics of a complete detection and provide a template so that you can gather such information in your organization. Then, we’ll dive into the sources that detection...
