Often times attackers will run scans against the network to identify different network and operating
systems, and resources that are available. If an attacker runs scans on the network, and you are
logging the connections, which of the following represent the legitimate combination of packets
that will be sent between the attacker and target?

A.
Attacker PSH-FIN Scan, Target RST-FIN Response

B.
Attacker ACK Scan, Target NULL Response

C.
Attacker NULL Scan, Target RST Response

D.
Attacker SYN Scan, Target NULL Response

E.
Attacker FIN Scan, Target RST Response
