Which is the normal response from live hosts to the discovery packets sent during a default Nmap sweep?
During a default Nmap sweep, a live host typically responds to a TCP SYN packet with a SYN-ACK packet. This response indicates that the port is open and the host is available to communicate. The SYN-ACK response is a standard part of the TCP three-way handshake process.
Nmap sends four packets to identify UP hosts when run as a privileged user: ICMP Echo Request TCP SYN to port 443 TCP ACK to port 80 ICMP Timestamp Request
