• Question 361:

  The GET method should never be used when sensitive data such as credit card is being sent to a CGI program. This is because any GET command will appear in the URL, and will be logged by any servers. For example, let's say that you've entered your credit card information into a form that uses the GET method. The URL may appear like this:

  https://www.xsecurity-bank.com/creditcard.asp?cardnumber=453453433532234

  The GET method appends the credit card number to the URL. This means that anyone with access to a server log will be able to obtain this information.

  How would you protect from this type of attack?

  A. Never include sensitive information in a script

  B. Use HTTPS SSLv3 to send the data instead of plain HTTPS

  C. Replace the GET with POST method when sending data

  D. Encrypt the data before you send using GET method

  Correct Answer: C

• Question 362:

  Perimeter testing means determining exactly what your firewall blocks and what it allows.

  To conduct a good test, you can spoof source IP addresses and source ports.

  Which of the following command results in packets that will appear to originate from the system at 10.8.8.8? Such a packet is useful for determining whether the firewall is allowing random packets in or out of your network.

  A. hping3 -T 10.8.8.8 -S netbios -c 2 -p 80

  B. hping3 -Y 10.8.8.8 -S windows -c 2 -p 80

• Question 367:

  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?

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

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

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

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