Direct and Indirect are ?

• A. Monitoring Techniques
• B. Survey Techniques
• C. Detection Techniques
• D. Sampling Techniques

Answer: (A)

Direct and indirect refer to monitoring techniques. In reconnaissance, monitoring is about observing what’s happening over time to gather information about a target. Direct monitoring means actively collecting data as it happens—real-time observation or live data capture. Indirect monitoring uses secondary information and artifacts to infer activity—such as logs, public records, metadata, or other sources that indicate what’s going on without watching in real time. Together, they describe the ways you monitor a situation, so Monitoring Techniques is the best fit.

Surveys are about asking questions to gather information, which isn’t about ongoing observation. Detection techniques focus on spotting events or anomalies. Sampling techniques involve selecting a subset of data for analysis, not the act of monitoring itself.
