Cindy is the network security administrator for her company. She just got back from a security
conference in Las Vegas where they talked about all kinds of old and new security threats; many of
which she did not know of. She is worried about the current security state of her company's network so
she decides to start scanning the network from an external IP address. To see how some of the hosts on
her network react, she sends out SYN packets to an IP range. A number of IPs responds with a SYN/ACK
response. Before the connection is established, she sends RST packets to those hosts to stop the session.
She has done this to see how her intrusion detection system will log the traffic. What type of scan is
Cindy attempting here?
