  5. A new wireless client is configured to join a 802.11 network. This client uses the same hardware and software as many of the other clients on the network. The client can see the network, but cannot connect. A wireless packet sniffer shows that the Wireless Access Point (WAP) is not responding to the association requests being sent by the wireless client. What is a possible source of this problem?

    • The WAP does not recognize the client’s MAC address
    • The client cannot see the SSID of the wireless network
    • Client is configured for the wrong channel
    • The wireless client is not configured to use DHCP
  6. What is correct about digital signatures?

    • A digital signature cannot be moved from one signed document to another because it is the hash of the original document encrypted with the private key of the signing party.
    • Digital signatures may be used in different documents of the same type.
    • A digital signature cannot be moved from one signed document to another because it is a plain hash of the document content.
    • Digital signatures are issued once for each user and can be used everywhere until they expire.
  7. What does a firewall check to prevent particular ports and applications from getting packets into an organization?

    • Transport layer port numbers and application layer headers
    • Presentation layer headers and the session layer port numbers
    • Network layer headers and the session layer port numbers
    • Application layer port numbers and the transport layer headers
  8. Which of the following programming languages is most susceptible to buffer overflow attacks, due to its lack of a built-in bounds checking mechanism?

    #include <string.h>
    int main(){
    char buffer[8];
    strcpy(buffer, ““11111111111111111111111111111””);

    • Python
    • Java
    • C++
  9. Scenario:
    1. Victim opens the attacker’s web site.
    2. Attacker sets up a web site which contains interesting and attractive content like ‘Do you want to make $1000 in a day?’.
    3. Victim clicks to the interesting and attractive content URL.
    4. Attacker creates a transparent ‘iframe’ in front of the URL which victim attempts to click, so victim thinks that he/she clicks to the ‘Do you want to make $1000 in a day?’ url but actually he/she clicks to the content or UPL that exists in the transparent ‘iframe’ which is setup by the attacker.

    What is the name of the attack which is mentioned in the scenario?

    • Session Fixation
    • HTML Injection
    • HTTP Parameter Pollution
    • Clickjacking Attack

    • TCP/IP doesn’t support ICMP.
    • You need to run the ping command with root privileges.
  13. A large mobile telephony and data network operator has a data center that houses network elements. These are essentially large computers running on Linux. The perimeter of the data center is secured with firewalls and IPS systems.

    What is the best security policy concerning this setup?

    • Network elements must be hardened with user ids and strong passwords. Regular security tests and audits should be performed.
    • As long as the physical access to the network elements is restricted, there is no need for additional measures.
    • There is no need for specific security measures on the network elements as long as firewalls and IPS systems exist.
    • The operator knows that attacks and down time are inevitable and should have a backup site.
