EC-COUNCIL EC-Council Certified Network Defender CND Sample Questions (Q258-Q263):

NEW QUESTION # 258
Frank is a network technician working for a medium-sized law firm in Memphis. Frank and two other IT employees take care of all the technical needs for the firm. The firm's partners have asked that a secure wireless network be implemented in the office so employees can move about freely without being tied to a network cable. While Frank and his colleagues are familiar with wired Ethernet technologies, 802.3, they are not familiar with how to setup wireless in a business environment. What IEEE standard should Frank and the other IT employees follow to become familiar with wireless?

Answer: A

Explanation:
The correct IEEE standard for wireless networking in a business environment is 802.11. This series of standards defines the protocols for implementing wireless local area network (WLAN) communications in various frequencies, including 2.4, 5, and 60 GHz bands. The 802.11 standards are widely used worldwide and form the basis of wireless network products that are marketed under the Wi-Fi brand. Frank and his colleagues should familiarize themselves with the
802.11 standards to set up a secure wireless network for their firm.


NEW QUESTION # 259
The network admin decides to assign a class B IP address to a host in the network. Identify which of the following addresses fall within a class B IP address range.

Answer: C


NEW QUESTION # 260
Which of the following tools is an open source network intrusion prevention and detection system that operates
as a network sniffer and logs activities of the network that is matched with the predefined signatures?

Answer: B

Explanation:
Snort is an open source network intrusion prevention and detection system that operates as a network sniffer.
It logs activities of the network that is matched with the predefined signatures. Signatures can be designed for
a wide range of traffic, including Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram
Protocol (UDP), and Internet Control Message Protocol (ICMP). The three main modes in which Snort can be
configured are as follows:
Sniffer mode: It reads the packets of the network and displays them in a continuous stream on the console.
Packet logger mode: It logs the packets to the disk.
Network intrusion detection mode: It is the most complex and configurable configuration, allowing Snort to
analyze network traffic for matches against a user-defined rule set.
Answer option A is incorrect. Dsniff is a set of tools that are used for sniffing passwords, e-mail, and HTTP
traffic. Some of the tools of Dsniff include dsniff, arpredirect, macof, tcpkill, tcpnice, filesnarf, and mailsnarf.
Dsniff is highly effective for sniffing both switched and shared networks. It uses the arpredirect and macof tools
for switching across switched networks. It can also be used to capture authentication information for FTP,
telnet, SMTP, HTTP, POP, NNTP, IMAP, etc.
Answer option D is incorrect. Kismet is a Linux-based 802.11 wireless network sniffer and intrusion detection
system. It can work with any wireless card that supports raw monitoring (rfmon) mode. Kismet can sniff
802.11b, 802.11a, 802.11g, and 802.11n traffic. Kismet can be used for the following tasks:
To identify networks by passively collecting packets
To detect standard named networks
To detect masked networks
To collect the presence of non-beaconing networks via data traffic
Answer option B is incorrect. KisMAC is a wireless network discovery tool for Mac OS
X. It has a wide range of
features, similar to those of Kismet, its Linux/BSD namesake and far exceeding those of NetStumbler, its
closest equivalent on Windows. The program is geared towards the network security professionals, and is not
as novice-friendly as the similar applications. KisMAC will scan for networks passively on supported cards,
including Apple's AirPort, AirPort Extreme, and many third-party cards. It will scan for networks actively on any
card supported by Mac OS X itself.
Cracking of WEP and WPA keys, both by brute force, and exploiting flaws, such as weak scheduling and badly
generated keys is supported when a card capable of monitor mode is used, and when packet reinsertion can
be done with a supported card. The GPS mapping can be performed when an NMEA compatible GPS receiver
is attached. Data can also be saved in pcap format and loaded into programs, such as Wireshark.


NEW QUESTION # 261
Which firewall technology can filler application-specific commands such as CET and POST requests?

Answer: A


NEW QUESTION # 262
Ryan, a network security engineer, after a recent attack, is trying to get information about the kind of attack his users were facing. He has decided to put into production one honeypot called Kojoney.
He is interested in emulating the network vulnerability, rather than the real vulnerability system, making this probe safer and more flexible. Which type of honeypot is he trying to implement?

Answer: C

Explanation:
Ryan is implementing a low interaction honeypot with Kojoney. Low interaction honeypots are designed to emulate services and applications to a certain degree without exposing the real underlying system. They provide a safe environment that can be used to study the attacker's behavior and methods without the risk of compromising the actual system. Kojoney, specifically, is a low interaction honeypot that emulates an SSH server. It uses minimal resources and is less complex compared to high interaction honeypots, making it easier to deploy and manage. By simulating network vulnerabilities rather than actual system vulnerabilities, Kojoney can attract attackers and record their interaction, which helps in understanding the attack patterns and potentially identifying the attackers.
