WebWhen you establish a new TCP connection (3 way handshake) then the initial sequence number is a random 32 bit value. The receiver will use this sequence number and sends back an acknowledgment. Protocol analyzers like wireshark will often use a relative sequence number of 0 since it’s easier to read than some high random number. WebUsing 3-way handshake, it is possible to check for open ports. a) True b) False View Answer 7.

This will initiate an entry in the firewall's state table.

WebThe three stages of a TCP connection—synchronize (SYN), synchronize-acknowledge (SYN-ACK), and acknowledge (ACK)—are used by a stateful inspection firewall to identify the parties involved in order to spot a potential threat.
