Provide a detailed description of how each of the following TCP flags are utilized: SYN (Synchronize) ACK (Acknowledgment) PSH (Push) URG (Urgent) RST (Reset) FIN (Finished)

Answer/Explanation:

SYN (Synchronize) :

The Synchronisation flag is a TCP flag used as a first step in establishing a 3-way handshake between two hosts.

ACK (Acknowledgment) :

The ACK flag is a TCP flag used to acknowledge the successful receipt of a packet.

PSH(Push):

The PSH flag is similar to the URG flag it tells the receiver to process packets as they are received instead of buffering them.

URG (Urgent) RST :

The URG flag is used to notify the receiver to process the urgent packets before processing all other packets. The receiver will be notified when all known urgent data has been received.

(Reset) FIN (Finished)::

The FIN flag means there is no more data from the sender. Therefore, it is used in the last packet sent from the sender
