Constructing a signature for detection involves:

The correct answer is A. Identifying unique patterns of attack. Constructing a detection signature means capturing the distinctive, repeatable characteristics of an attack - specific byte sequences, behavioral patterns, network traffic anomalies, or registry changes - so that a security tool (IDS/IPS, SIEM, AV) can reliably recognize that…

Explanation

Constructing a detection signature means capturing the distinctive, repeatable characteristics of an attack - specific byte sequences, behavioral patterns, network traffic anomalies, or registry changes - so that a security tool (IDS/IPS, SIEM, AV) can reliably recognize that attack when it occurs again. Option B (estimating cost) and Option D (calculating downtime) are business-impact activities, not technical detection engineering tasks. Option C (predicting future vectors) describes threat intelligence or forecasting work, which precedes signature creation but is not the act of building one.

Memory tip: Think of a signature like a criminal's fingerprint - you're not guessing what crime they'll commit next (C) or tallying the damage (B/D); you're capturing the unique mark they leave behind so you can ID them on sight.
