NEW QUESTION 64
Which of the following is a technique for gathering information about a remote network protected by a firewall?

• A. Warchalking
• B. Firewalking
• C. Wardialing
• D. Wardriving

Answer: B

Explanation:
Fire walking is a technique for gathering information about a remote network protected by a firewall. This technique can be used effectively to perform information gathering attacks. In this technique, an attacker sends a crafted packet with a TTL value that is set to expire one hop past the firewall. If the firewall allows this crafted packet through, it forwards the packet to the next hop. On the next hop, the packet expires and elicits an ICMP
"TTL expired in transit" message to the attacker. If the firewall does not allow the traffic, there should be no response, or an ICMP "administratively prohibited" message should be returned to the attacker. A malicious attacker can use firewalking to determine the types of ports/protocols that can bypass the firewall. To use firewalking, the attacker needs the IP address of the last known gateway before the firewall and the IP address of a host located behind the firewall. The main drawback of this technique is that if an administrator blocks ICMP packets from leaving the network, it is ineffective.
Answer option B is incorrect. Warchalking is the drawing of symbols in public places to advertise an open Wi-Fi wireless network. Having found a Wi-Fi node, the warchalker draws a special symbol on a nearby object, such as a wall, the pavement, or a lamp post. The name warchalking is derived from the cracker terms war dialing and war driving.
Answer option C is incorrect. War driving, also called access point mapping, is the act of locating and possibly exploiting connections to wireless local area networks while driving around a city or elsewhere. To do war driving, one needs a vehicle, a computer (which can be a laptop), a wireless Ethernet card set to work in promiscuous mode, and some kind of an antenna which can be mounted on top of or positioned inside the car.
Because a wireless LAN may have a range that extends beyond an office building, an outside user may be able to intrude into the network, obtain a free Internet connection, and possibly gain access to company records and other resources.
Answer option D is incorrect. War dialing or wardialing is a technique of using a modem to automatically scan a list of telephone numbers, usually dialing every number in a local area code to search for computers, Bulletin board systems, and fax machines. Hackers use the resulting lists for various purposes, hobbyists for exploration, and crackers - hackers that specialize in computer security - for password guessing.

 

NEW QUESTION 65

• C. bandwidth
• D. routing delay
• E. length of the trail

Answer: D

 

NEW QUESTION 66
Which of the following key features is used by TCP in order to regulate the amount of data sent by a host to
another host on the network?

• A. TCP timestamp
• B. Congestion control
• C. Flow control
• D. Sequence number

Answer: C

Explanation:
Flow control is the process of regulating the amount of data sent by a host to another host on the network. The
flow control mechanism controls packet flow so that a sender does not transmit more packets than a receiver
can process. TCP uses a sliding window flow control protocol. In each TCP segment, the receiver specifies in
the receive window field the amount of additional received data (in bytes) that it is willing to buffer for the
connection. The sending host can send only up to that amount of data before it must wait for an
acknowledgment and window update from the receiving host.
Answer option A is incorrect. TCP uses a sequence number for identifying each byte of data.
Answer option B is incorrect. TCP timestamp helps TCP to compute the round-trip time between the sender
and receiver.
Answer option C is incorrect. Congestion control concerns controlling traffic entry into a telecommunications
network, so as to avoid congestive collapse by attempting to avoid oversubscription of any of the processing or
link capabilities of the intermediate nodes and networks and taking resource reducing steps, such as reducing
the rate of sending packets. It should not be confused with flow control, which prevents the sender from
overwhelming the receiver.

NEW QUESTION 69
Which of the following steps of the OPSEC process examines each aspect of the planned operation to identify
OPSEC indicators that could reveal critical information and then compare those indicators with the adversary's
intelligence collection capabilities identified in the previous action?

• A. Analysis of Threats
• B. Assessment of Risk
• C. Analysis of Vulnerabilities
• D. Application of Appropriate OPSEC Measures
• E. Identification of Critical Information

Answer: C

Explanation:
OPSEC is a 5-step process that helps in developing protection mechanisms in order to safeguard sensitive
information and preserve essential secrecy.
The OPSEC process has five steps, which are as follows:
1.Identification of Critical Information: This step includes identifying information vitally needed by an adversary,
which focuses the remainder of the OPSEC process on protecting vital information, rather than attempting to
protect all classified or sensitive unclassified information.
2.Analysis of Threats: This step includes the research and analysis of intelligence, counter-intelligence, and
open source information to identify likely adversaries to a planned operation.
3.Analysis of Vulnerabilities: It includes examining each aspect of the planned operation to identify OPSEC
indicators that could reveal critical information and then comparing those indicators with the adversary's
intelligence collection capabilities identified in the previous action.
4.Assessment of Risk: Firstly, planners analyze the vulnerabilities identified in the previous action and identify
possible OPSEC measures for each vulnerability. Secondly, specific OPSEC measures are selected for
execution based upon a risk assessment done by the commander and staff.
5.Application of Appropriate OPSEC Measures: The command implements the OPSEC measures selected in
the assessment of risk action or, in the case of planned future operations and activities, includes the measures
in specific OPSEC plans.

NEW QUESTION 74
Which of the following statements are TRUE about Demilitarized zone (DMZ)?
Each correct answer represents a complete solution. Choose all that apply.

• A. Demilitarized zone is a physical or logical sub-network that contains and exposes external services of an organization to a larger un-trusted network.
• B. The purpose of a DMZ is to add an additional layer of security to the Local Area Network of an organization.
• C. Hosts in the DMZ have full connectivity to specific hosts in the internal network.
• D. In a DMZ configuration, most computers on the LAN run behind a firewall connected to a public network like the Internet.

Answer: A,B,D

Explanation:
A demilitarized zone (DMZ) is a physical or logical subnetwork that contains and exposes external services of an organization to a larger network, usually the Internet. The purpose of a DMZ is to add an additional layer of security to an organization's Local Area Network (LAN); an external attacker only has access to equipment in the DMZ, rather than the whole of the network. Hosts in the DMZ have limited connectivity to specific hosts in the internal network, though communication with other hosts in the DMZ and to the external network is allowed. This allows hosts in the DMZ to provide services to both the internal and external networks, while an intervening firewall controls the traffic between the DMZ servers and the internal network clients. In a DMZ configuration, most computers on the LAN run behind a firewall connected to a public network such as the Internet.
