One type of port scan can determine which ports are in a listening state on the network, and can
then perform a two way handshake.
Which type of port scan can perform this set of actions?
A.
A TCP (transmission Control Protocol) fin scan
B.
A TCP (transmission Control Protocol) connect scan
C.
A TCP (transmission Control Protocol) null scan
D.
A TCP (transmission Control Protocol) SYN (Synchronize) scan
Explanation:
In SYN scanning, a TCP SYN packet is sent to the port(s) to be scanned. If the port responds with
a TCP SYN ACK packet, then the port is listening. If it replies with a TCP RST packet, then it is
not.
