SYN (TCP)

*** Shopping-Tip: SYN (TCP)
'''SYN''' (synchronize) is a type of packet used by the Transmission Control Protocol (TCP) when initiating a new connection to synchronize the sequence numbers on two connecting computers. The SYN is acknowledged by a SYN/ACK by the responding computer. A type of denial of service attack known as a SYN flood involves sending large numbers of SYN packets and ignoring the return, thereby forcing the server to keep track of a large number of half-open connections. {{compu-network-stub}} Category:TCP/IP es:SYN
