QUESTION 34
Which of the following technologies is used to detect unauthorized attempts to access and manipulate
computer systems locally or through the Internet or an intranet?
A. Demilitarized zone (DMZ)
B. Firewall
C. Intrusion detection system (IDS)
D. Packet filtering
Correct Answer: C
Explanation
Explanation/Reference:
An Intrusion detection system (IDS) is used to detect unauthorized attempts to access and manipulate
computer systems locally or through the Internet or an intranet. It can detect several types of attacks and
malicious behaviors that can compromise the security of a network and computers. This includes network
attacks against vulnerable services, unauthorized logins and access to sensitive data, and malware (e.g.
viruses, worms, etc.). An IDS also detects attacks that originate from within a system. In most cases, an
IDS has three main components: Sensors, Console, and Engine. Sensors generate security events. A
console is used to alert and control sensors and to monitor events. An engine is used to record events and
to generate security alerts based on received security events. In many IDS implementations, these three
components are combined into a single device. Basically, following two types of IDS are used :
Network-based IDSHost-based IDS
Answer option D is incorrect. Packet filtering is a method that allows or restricts the flow of specific types of
packets to provide security. It analyzes the incoming and outgoing packets and lets them pass or stops
them at a network interface based on the source and destination addresses, ports, or protocols. Packet
filtering provides a way to define precisely which type of IP traffic is allowed to cross the firewall of an
intranet. IP packet filtering is important when users from private intranets connect to public networks, such
as the Internet.
Answer option B is incorrect. A firewall is a tool to provide security to a network. It is used to protect an
internal network or intranet against unauthorized access from the Internet or other outside networks. It
restricts inbound and outbound access and can analyze all traffic between an internal network and the
Internet. Users can configure a firewall to pass or block packets from specific IP addresses and ports.
Answer option A is incorrect. Demilitarized zone (DMZ) or perimeter network is a small network that lies in
between the Internet and a private network. It is the boundary between the Internet and an internal
network, usually a combination of firewalls and bastion hosts that are gateways between inside networks
and outside networks. DMZ provides a large enterprise network or corporate network the ability to use the
Internet while still maintaining its security.

QUESTION 44
Which of the following types of attacks entices a user to disclose personal information such as social
security number, bank account details, or credit card number?
A. Password guessing attack
B. Spoofing
C. Phishing
D. Replay attack
Correct Answer: C
Explanation
Explanation/Reference:
Phishing is a type of scam that entice a user to disclose personal information such as social security
number, bank account details, or credit card number. An example of phishing attack is a fraudulent e-mail
that appears to come from a user’s bank asking to change his online banking password. When the user
clicks the link available on the e-mail, it directs him to a phishing site which replicates the original bank
site. The phishing site lures the user to provide his personal information. Answer option B is incorrect.
Spoofing is a technique that makes a transmission appear to have come from an authentic source by
forging the IP address, email address, caller ID, etc. In IP spoofing, a hacker modifies packet headers by
using someone else’s IP address to his identity. However, spoofing cannot be used while surfing the
Internet, chatting on- line, etc. because forging the source
IP address causes the responses to be misdirected. Answer option D is incorrect. Replay attack is a type
of attack in which attackers capture packets containing passwords or digital signatures whenever packets
pass between two hosts on a network.
In an attempt to obtain an authenticated connection, the attackers then resend the captured packet to the
system.
Answer option A is incorrect. A password guessing attack occurs when an unauthorized user tries to log
on repeatedly to a computer or network by guessing usernames and passwords. Many password guessing
programs that attempt to break passwords are available on the Internet. Following are the types of
password guessing attacks:
Brute force attack
Dictionary attack

B. It has a maximum transmission range of 200 meters.
C. It does not require a line-of-sight connection between devices.
D. It requires a line-of-sight connection between devices.
Correct Answer: AC
Explanation
Explanation/Reference:
Bluetooth is a standard for very low powered and short-range radio connections. As a radio technology, it
does not require a line-of-sight connection as an infrared connection does. Bluetooth is used to link
Personal Digital Assistant (PDA), mobile phones, and laptops, and provides them with Internet access via
hot spots. It uses the 2.4 Ghz spectrums with a data transfer rate of about 1
Mbps. Bluetooth networks are not permanent as compared to other networks where a central
communication point is needed such as a hub or a router. A Bluetooth network can be formed when two
Bluetooth devices are within a range of ten meters, enabling them to communicate directly with each other.
This dynamically created network is known as a piconet. A Bluetooth-enabled device can support up to
seven other Bluetooth devices in a master-slave relationship; the first Bluetooth device is the master, and
all the other devices are slaves that communicate with the master in one piconet. The maximum
transmission range of Bluetooth is around 10 meters.
Answer option D is incorrect. The infrared devices require a line-of-sight connection between devices.
Answer option B is incorrect. The maximum transmission range of Bluetooth is around 10 meters.
