SYN scan is another form of TCP scanning. Rather than using the operating system's network functions, the port scanner generates raw IP packets itself, and monitors for responses. This scan type is also known as "half-open scanning", because it never actually opens a full TCP connection. The port scanner generates a SYN packet.
An idle scan is a TCP port scan method for determining what services are open on a target computer [1] without leaving traces pointing back at oneself. This is accomplished by using packet spoofing to impersonate another computer (called a " zombie ") so that the target believes it's being accessed by the zombie.
RST: 1 bit Reset the connection SYN: 1 bit Synchronize sequence numbers. Only the first packet sent from each end should have this flag set. Some other flags and fields change meaning based on this flag, and some are only valid when it is set, and others when it is clear. FIN: 1 bit Last packet from sender Window: 16 bits

The term half-open connection can also be used to describe an embryonic connection, i.e. a TCP connection that is in the process of being established. TCP has a three state system for opening a connection. First, the originating endpoint (A) sends a SYN packet to the destination (B). A is now in an embryonic state (specifically, SYN_SENT), and ...
