Question:
Which of the following information is false?
A. nmap can be used to get reverse dns names
B. ps displays the currently-running processes.
C. nmap sends specially crafted packets to the target host and then analyzes the responses.
D. top displays the top CPU processes
Explanation:
nmap (network mapper) is a security scanner used to discover hosts and services on a computer network, thus creating the "map" of the network. To accomplish this goal, nmap sends specially crafted packets to the target host and then analyzes the responses.
Unlike many simple port scanners that just send packets at some predefined constant rate, nmap accounts for the network conditions (latency fluctuations, network congestion, the target interference with the scan) during the run.
