Steve is working as an analyst for Highlanders & Co.

The method described involves analyzing activities, timeframes, dependencies, and milestones to understand project flow and relationships. This is known as Critical Path Analysis (CPA).

Critical Path Analysis helps identify the sequence of crucial tasks that determine the overall project duration. In the context of threat intelligence, it assists analysts in mapping adversary activities or operational timelines to determine key steps and dependencies in attack campaigns.

Why the Other Options Are Incorrect:

B. Timeline analysis: Focuses on chronological sequencing of events, not dependency or duration analysis.

C. Cone of plausibility: Used for scenario modeling and forecasting possible outcomes.

D. Analogy analysis: Compares new situations to historical cases, not time-dependent task mapping.

Conclusion:

Steve applied Critical Path Analysis to determine activity dependencies and durations.

Final Answer: A. Critical path analysis

Explanation Reference (Based on CTIA Study Concepts):

CTIA defines CPA as a structured approach for mapping and analyzing sequences of dependent activities or events.
