Duration malware remains undetected in a system.

• A. Remediation and Response
• B. Detection
• C. Collective Intelligence
• D. Malware Dwell Time

Answer: (D)

Malware dwell time is the period that malware stays in a system undetected before it’s found and removed. This metric is central because the longer malicious code remains hidden, the more opportunity the attacker has to move laterally, escalate privileges, steal data, or lock files, increasing damage and complicating cleanup. The term directly captures the idea of how long the malware operates unseen, which is why it’s the best answer here.

Detection describes the ability to identify threats, not how long they’ve been present. Remediation and Response refer to actions taken after a threat is found, not the duration the threat was in the environment. Collective Intelligence involves sharing threat information to improve defenses, not the length of time malware remains undetected. So the concept being tested is the duration malware remains undetected, i.e., malware dwell time.
