Question 8

You are utilizing the Analysis of Competing Hypotheses (ACH) matrix to evaluate a potential APT intrusion. After populating your hypotheses and evidence, you notice that your primary hypothesis has a high number of 'consistent' evidence ratings but several 'contradictory' data points. How should you proceed according to standard ACH methodology?

Accepted Answer

Refine the evidence definitions to focus on the contradictory data points to assess if the hypothesis remains viable.. ACH methodology dictates that you should focus on evidence that disproves hypotheses rather than supports them. Finding contradictory evidence is more diagnostic than finding supporting evidence.

Discard the hypothesis immediately if any contradictory evidence exists.

Answer

Increase the weight of supporting evidence to balance the matrix.
