Which of the following is NOT a step in regressive analysis?

The question aims to outline the steps involved in regressive analysis, which is a method used to examine the effects of implemented countermeasures on vulnerabilities. The correct response highlights that analyzing potential vulnerabilities related to specific assets is not a step in regressive analysis.

Regressive analysis primarily focuses on evaluating the effectiveness of current countermeasures by looking at what vulnerabilities still remain, identifying ineffective countermeasures, and assessing the vulnerabilities of an asset in an unprotected state. This process is about understanding and evaluating the impact of existing protections rather than identifying vulnerabilities that could potentially exist. By understanding what vulnerability currently exists with the implemented countermeasures in place, one can reassess and refine security measures more effectively.

Therefore, identifying potential vulnerabilities related to specific assets falls outside the scope of regressive analysis. Instead, that activity is more aligned with a preliminary assessment or threat analysis phase, where one seeks to recognize all possible vulnerabilities before any defenses are applied. This distinction is crucial for risk management as it informs the ongoing development and refinement of security strategies within DoD programs.
