Partial IDS failure affects detection in areas where?

Partial IDS failure affects detection in areas where?

• A. Two or more sensors form a line of detection at the boundary
• B. One sensor fails
• C. All sensors fail
• D. No impact on detection

Answer: (A)

The idea here is that perimeter detection is built from lines of detection created by multiple sensors working together. Those lines form the boundary between protected and unprotected areas. When a partial IDS failure occurs, the most noticeable impact shows up along those boundary lines, where two or more sensors contribute to the detection. If a sensor along such a line fails, that line’s effectiveness is weakened exactly along that boundary, creating a gap or reduced detection there. Areas away from those boundary lines or covered by other lines may still be monitored, but the boundary where the line is defined by multiple sensors becomes vulnerable. So the partial failure affects detection in the regions where two or more sensors form a line of detection at the boundary.
