What techniques would you use to evade IDS during a Port Scan? (Select 4 answers)

Bob was frustrated with his competitor, Brownies Inc., and decided to launch an attack that would
result in serious financial losses. He planned the attack carefully and carried out the attack at the
appropriate moment.
Meanwhile, Trent, an administrator at Brownies Inc., realized that their main financial transaction
server had been attacked. As a result of the attack, the server crashed and Trent needed to reboot
the system, as no one was able to access the resources of the company. This process involves
human interaction to fix it.
What kind of Denial of Service attack was best illustrated in the scenario above?

Johnny is a member of the hacking group Orpheus1. He is currently working on breaking into the
Department of Defense’s front end Exchange Server. He was able to get into the server, located in
a DMZ, by using an unused service account that had a very weak password that he was able to
guess. Johnny wants to crack the administrator password, but does not have a lot of time to crack
it. He wants to use a tool that already has the LM hashes computed for all possible permutations
of the administrator password.
What tool would be best used to accomplish this?

The FIN flag is set and sent from host A to host B when host A has no more data to transmit
(Closing a TCP connection). This flag releases the connection resources. 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.

In this type of Man-in-the-Middle attack, packets and authentication tokens are captured using a
sniffer. Once the relevant information is extracted, the tokens are placed back on the network to
gain access.

Leesa is the senior security analyst for a publicly traded company. The IT department recently
rolled out an intranet for company use only with information ranging from training, to holiday
schedules, to human resources data. Leesa wants to make sure the site is not accessible from
outside and she also wants to ensure the site is Sarbanes-Oxley (SOX) compliant. Leesa goes to
a public library as she wants to do some Google searching to verify whether the company’s
intranet is accessible from outside and has been indexed by Google. Leesa wants to search for a
website title of “intranet” with part of the URL containing the word “intranet” and the words “human

resources” somewhere in the webpage.
What Google search will accomplish this?

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?
