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.
This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The (TCP) and the (UDP) only need one for , bidirectional traffic. They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist.
Superscan is a tool used by system administrators, crackers and script kiddies to evaluate a computer's security. System administrators can use it to test for possible unauthorised open ports on their computer networks , whereas crackers use it to scan for insecure ports in order to gain illegal access to a system.
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 ...
