• Question 253:

  Harold works for Jacobson Unlimited in the IT department as the security manager. Harold has created a security policy requiring all employees to use complex 14 character passwords.

  Unfortunately, the members of management do not want to have to use such long complicated passwords so they tell Harold's boss this new password policy should not apply to them. To comply with the management's wishes, the IT department creates another Windows domain and moves all the management users to that domain. This new domain has a password policy only requiring 8 characters.

  Harold is concerned about having to accommodate the managers, but cannot do anything about it. Harold is also concerned about using LanManager security on his network instead of NTLM or NTLMv2, but the many legacy applications on the network prevent using the more secure NTLM and NTLMv2. Harold pulls the SAM files from the DC's on the original domain and the new domain using Pwdump6.

  Harold uses the password cracking software John the Ripper to crack users' passwords to make sure they are strong enough. Harold expects that the users' passwords in the original domain will take much longer to crack than the management's passwords in the new domain. After running the software, Harold discovers that the 14 character passwords only took a short time longer to crack than the 8 character passwords.

  Why did the 14 character passwords not take much longer to crack than the 8 character passwords?

  A. Harold should have used Dumpsec instead of Pwdump6

  B. Harold's dictionary file was not large enough

  C. Harold should use LC4 instead of John the Ripper

  D. LanManger hashes are broken up into two 7 character fields

  Correct Answer: D

• Question 254:

  Jess the hacker runs L0phtCrack's built-in sniffer utility that grabs SMB password hashes and stores them for offline cracking. Once cracked, these passwords can provide easy access to whatever network resources the user account has access to. But Jess is not picking up hashes from the network.

  Why?

  A. The network protocol is configured to use SMB Signing

  B. The physical network wire is on fibre optic cable

  C. The network protocol is configured to use IPSEC

  D. L0phtCrack SMB sniffing only works through Switches and not Hubs

  Correct Answer: A

• Question 256:

  LAN Manager Passwords are concatenated to 14 bytes, and split in half. The two halves are hashed individually. If the password is 7 characters or less, than the second half of the hash is always:

  A. 0xAAD3B435B51404EE

  B. 0xAAD3B435B51404AA

  C. 0xAAD3B435B51404BB

• Question 257:

  Hampton is the senior security analyst for the city of Columbus in Ohio. His primary responsibility is to ensure that all physical and logical aspects of the city's computer network are secure from all angles. Bill is an IT technician that works with Hampton in the same IT department. Bill's primary responsibility is to keep PC's and servers up to date and to keep track of all the agency laptops that the company owns and lends out to its employees. After Bill setup a wireless network for the agency, Hampton made sure that everything was secure. He instituted encryption, rotating keys, turned off SSID broadcasting, and enabled MAC filtering. According to agency policy, only company laptops are allowed to use the wireless network, so Hampton entered all the MAC addresses for those laptops into the wireless security utility so that only those laptops should be able to access the wireless network.

  Hampton does not keep track of all the laptops, but he is pretty certain that the agency only purchases Dell laptops. Hampton is curious about this because he notices Bill working on a Toshiba laptop one day and saw that he was on the Internet. Instead of jumping to conclusions, Hampton decides to talk to Bill's boss and see if they had purchased a Toshiba laptop instead of the usual Dell. Bill's boss said no, so now Hampton is very curious to see how Bill is accessing the Internet. Hampton does site surveys every couple of days, and has yet to see any outside wireless network signals inside the company's building.

  How was Bill able to get Internet access without using an agency laptop?

  A. Bill spoofed the MAC address of Dell laptop

  B. Bill connected to a Rogue access point

  C. Toshiba and Dell laptops share the same hardware address

  D. Bill brute forced the Mac address ACLs

  Correct Answer: A

  However, host A can continue to receive data as long as the SYN sequence numbers of transmitted packets from host B are lower than the packet segment containing the set FIN flag.

  A. false

  B. true

  Correct Answer: B
