    • List weak points on their network
    • Use attack as a launching point to penetrate deeper into the network
    • Demonstrate that no system can be protected against DoS attacks

  8. Paul’s company is in the process of undergoing a complete security audit including logical and physical security testing. After all logical tests were performed; it is now time for the physical round to begin. None of the employees are made aware of this round of testing. The security-auditing firm sends in a technician dressed as an electrician. He waits outside in the lobby for some employees to get to work and follows behind them when they access the restricted areas. After entering the main office, he is able to get into the server room telling the IT manager that there is a problem with the outlets in that room. What type of attack has the technician performed?

    • Tailgating
    • Backtrapping
    • Man trap attack
    • Fuzzing
  9. On Linux/Unix based Web servers, what privilege should the daemon service be run under?

    • Guest
    • Root
    • You cannot determine what privilege runs the daemon service
    • Something other than root
  10. What will the following URL produce in an unpatched IIS Web Server? co%af../..%co%af../windows/system32/cmd.exe?/c+dir+c:\

    • Directory listing of C: drive on the web server
    • Insert a Trojan horse into the C: drive of the web server
    • Execute a buffer flow in the C: drive of the web server
    • Directory listing of the C:\windows\system32 folder on the web server
  11. What is kept in the following directory? HKLM\SECURITY\Policy\Secrets

    • Cached password hashes for the past 20 users
    • Service account passwords in plain text
    • IAS account names and passwords
    • Local store PKI Kerberos certificates

    • %systemroot%\system32\LSA
    • %systemroot%\system32\drivers\etc
    • %systemroot%\repair
    • %systemroot%\LSA

    • allinurl:”exchange/logon.asp”
    • intitle:”exchange server”
    • locate:”logon page”
    • outlook:”search”
  14. When setting up a wireless network with multiple access points, why is it important to set each access point on a different channel?

    • Multiple access points can be set up on the same channel without any issues
    • Avoid over-saturation of wireless signals
    • So that the access points will work on different frequencies
    • Avoid cross talk
  15. You are running through a series of tests on your network to check for any security vulnerabilities.

    After normal working hours, you initiate a DoS attack against your external firewall. The firewall Quickly freezes up and becomes unusable.

  18. After passing her CEH exam, Carol wants to ensure that her network is completely secure. She implements a DMZ, stateful firewall, NAT, IPSEC, and a packet filtering firewall. Since all security measures were taken, none of the hosts on her network can reach the Internet. Why is that?

    • Stateful firewalls do not work with packet filtering firewalls
    • NAT does not work with stateful firewalls
    • IPSEC does not work with packet filtering firewalls
    • NAT does not work with IPSEC
  19. Jason has set up a honeypot environment by creating a DMZ that has no physical or logical access to his production network. In this honeypot, he has placed a server running Windows Active Directory. He has also placed a Web server in the DMZ that services a number of web pages that offer visitors a chance to download sensitive information by clicking on a button. A week later, Jason finds in his network logs how an intruder accessed the honeypot and downloaded sensitive information. Jason uses the logs to try and prosecute the intruder for stealing sensitive corporate information. Why will this not be viable?

    • Enticement
    • Intruding into a honeypot is not illegal
    • Intruding into a DMZ is not illegal
