Describe the SYN flag and how it is used in the three-way handshake.
What will be an ideal response?
The SYN flag is sent from one computer to another when a connection is initiated; the two computers are attempting to synchronize a connection. In the TCP three-way handshake, the initiator of the communication sends a packet with the SYN flag set. The normal response is a TCP packet with the SYN and ACK flags set. The initiator then responds with an ACK flag set.
