Question 4: What’s the three-way handshake?
Answer: A three-way Handshake (also known TCP-3way Handshake) is a way to establish a connection between client and server over TCP/IP networks. This mechanism allows the client and server to send each other acknowledgement and synchronization packets before any data transmission takes place.
Three-way handshake: The client sends a SYN TCP packet asking for a connection request (synchronizing) and a sequence number to the server. The server replies with the SYN/ACK packet acknowledging the connection request. It also assigns a sequence number. To accept the server’s response, the client sends an ACK packet.
Question 5: What exactly is data leakage? Describe it in your own words.
