A penetration tester has been given an assignment to attack a series of targets in the 192.168.1.0/24 range, triggering as few alarms and countermeasures as possible.
Which of the following Nmap scan syntaxes would BEST accomplish this objective?
Correct Answer: D. nmap -sS -O 192.168.1.2/24 -T1
The goal is to scan a network stealthily, minimizing alarms and avoiding detection by IDS/IPS. The correct answer must use a low-noise scanning technique with a slow timing template to evade detection.
nmap -sS -O 192.168.1.2/24 -T1-sS → SYN scan (Stealth Scan)
-sT) and less likely to trigger alarms.-O → OS Detection
192.168.1.2/24 → Scans the entire subnet (192.168.1.0 - 192.168.1.255)-T1 → Very slow timing template (Paranoid Mode)
Why the Other Options Are Incorrect:
nmap -sT -vvv -O 192.168.1.2/24 -PO
-sT → TCP Connect Scan
-vvv → Very verbose output (good for user, but not for stealth).-PO → Disables ping checks, which could make scanning less efficient but does not help stealth much.-sT.nmap -sV 192.168.1.2/24 -PO
-sV → Version detection
-PO → Disables ICMP ping, but this alone does not make scanning stealthy.-sV is aggressive and not stealthy.nmap -sA -v -O 192.168.1.2/24
-sA → ACK Scan
-sA is not useful for discovering targets.No Payment Cards Needed
