Answer:
c) Syn flooding is a form of denial of service attack in which a hostile client repeatedly sends SYN packets to every port on the server using fake IP addresses.
Explanation:
In the TCP/IP communication, when a client wants to establish a connection with a server, it sends a SYN (synchronize) packet to the server's port. The server then responds with a SYN-ACK (synchronize-acknowledge) packet, and the client responds with an ACK (acknowledge) packet. This process is called the "three-way handshake" and it establishes a connection between the client and server.
In a SYN flood attack, the attacker sends a large number of SYN packets to the server, but never completes the three-way handshake by sending the final ACK packet. This causes the server to wait for the non-existent ACK packets, tying up resources and making the server unavailable to legitimate clients.
