Slower scans are less detectable?

• A. Faster scans are less detectable
• B. Slower scans are more detectable
• C. Slower scans are less detectable
• D. Timing templates do not affect detectability

Answer: (C)

Slower scans are less detectable because sending fewer packets per second makes the probing activity blend more with normal network traffic. Security systems, rate limits, and IDS/IPS heuristics often flag rapid, high-volume scans, so dialing down the scan speed reduces the chances of triggering alarms. Nmap’s timing templates let you trade speed for stealth, with slower settings producing quieter probes. That’s why the statement is correct: slower scans tend to be less detectable. In contrast, faster scans generate more traffic and are more likely to be noticed, and timing templates definitely affect detectability.
