Question 32

Some passwords are stored using specialized encryption algorithms known as hashes. Why is this an appropriate method?

Options:

It is impossible to crack hashed user passwords unless the key used to encrypt them is obtained.

If a user forgets the password, it can be easily retrieved using the hash key stored by administrators.

Hashing is faster compared to more traditional encryption algorithms.

Passwords stored using hashes are non-reversible, making finding the password much more difficult.

Question 33

Hayden is the network security administrator for her company, a large finance firm based in Miami. Hayden just returned 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. Hayden 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 does this to see how her intrusion detection system will log the traffic. What type of scan is Hayden attempting here?

Options:

Hayden is attempting to find live hosts on her company's network by using an XMAS scan

She is utilizing a SYN scan to find live hosts that are listening on her network

The type of scan, she is using is called a NULL scan

Hayden is using a half-open scan to find live hosts on her network
