NEW QUESTION # 81
To secure his company's network, Tim the network admin, installed a security device that inspected all inbound and outbound network traffic for suspicious patterns. The device was configured to alert him if it found any such suspicious activity. Identify the type of network security device installed by Tim?
- A. Firewall
- B. Honeypot
- C. Proxy server
- D. Intrusion Detection System (IDS)
Answer: D
Explanation:
The network security device described is an Intrusion Detection System (IDS). An IDS monitors all inbound and outbound network traffic for suspicious patterns and is configured to alert the network administrator if it detects any such activity. This aligns with the primary function of an IDS, which is to serve as a monitoring system, not necessarily to block traffic like a firewall or act as a decoy like a honeypot. It differs from a proxy server, which would primarily manage and forward web requests on behalf of clients. The IDS operates by analyzing traffic and identifying potential threats based on known signatures or anomalies in network behavior, thereby enabling the network admin to take appropriate action to secure the network12.
References: The explanation provided is based on standard network security practices and the functionalities of an Intrusion Detection System (IDS) as outlined in network security resources. For detailed and specific references, please consult the latest Certified Network Defender (CND) study materials and documents provided by the EC-Council.
NEW QUESTION # 82
Which of the following attacks is a class of brute force attacks that depends on the higher likelihood of collisions found between random attack attempts and a fixed degree of permutations?
- A. Replay attack
- B. Phishing attack
- C. Birthday attack
- D. Dictionary attack
Answer: C
Explanation:
A birthday attack is a class of brute force attacks that exploits the mathematics behind the birthday problem in probability theory. It is a type of cryptography attack. The birthday attack depends on the higher likelihood of collisions found between random attack attempts and a fixed degree of permutations. Answer option D is incorrect. A dictionary attack is a technique for defeating a cipher or authentication mechanism by trying to determine its decryption key or passphrase by searching likely possibilities.A dictionary attack uses a brute-force technique of successively trying all the words in an exhaustive list (from a pre-arranged list of values). In contrast with a normal brute force attack, where a large proportion key space is searched systematically, a dictionary attack tries only those possibilities which are most likely to succeed, typically derived from a list of words in a dictionary. Generally, dictionary attacks succeed because many people have a tendency to choose passwords which are short (7 characters or fewer), single words found in dictionaries, or simple, easily-predicted variations on words, such as appending a digit. Answer option A is incorrect. Phishing is a type of internet fraud attempted by hackers. Hackers try to log into system by masquerading as a trustworthy entity and acquire sensitive information, such as, username, password, bank account details, credit card details, etc. After collecting this information, hackers try to use this information for their gain. Answer option B is incorrect. A replay attack is a form of network attack in which a valid data transmission is maliciously or fraudulently repeated or delayed. This is carried out either by the originator or by an adversary who intercepts the data and retransmits it, possibly as part of a masquerade attack by IP packet substitution.
NEW QUESTION # 83
Identify the spread spectrum technique that multiplies the original data signal with a pseudo random noise spreading code.
- A. DSSS
- B. OFDM
- C. ISM
- D. FHSS
Answer: A
Explanation:
The spread spectrum technique that involves multiplying the original data signal with a pseudo-random noise spreading code is known as Direct Sequence Spread Spectrum (DSSS). In DSSS, the data signal is combined with a higher data-rate bit sequence, also known as a chipping code, which divides the data according to a spreading ratio. The chipping code is a pseudo-random code sequence that spreads the signal across a wider bandwidth. This process allows the signal to be more resistant to interference and eavesdropping.

NEW QUESTION # 85
Steven is a Linux system administrator at an IT company. He wants to disable unnecessary services in the system, which can be exploited by the attackers. Which among the following is the correct syntax for disabling a service?
- A. $ sudo systemctl disable [service]
- B. $ sudo system-ctl disable [service]
- C. $ sudo system ctl disable [service]
- D. $ sudo system.ctl disable [service]
Answer: A
Explanation:
The correct syntax to disable a service in Linux using the systemctl command is sudo systemctl disable
[service-name]. This command is used to prevent a service from starting automatically at boot.
The systemctl command is part of the systemd system and service manager, which is used by many Linux distributions to bootstrap the user space and manage system processes after booting. This is the standard way to manage services on systems that use systemd.
References: The information is consistent with the usage of the systemctl command as described in various Linux documentation and resources, including the official ECCouncil Network Defender (CND) course materials. It is also corroborated by authoritative sources on Linux service management12.

CORRECT TEXT
Fill in the blank with the appropriate term.The ______________is a communication protocol that communicates information between the network routers and the multicast end stations.
Answer:
Explanation:
IGMP
Explanation:
The Internet Group Management Protocol (IGMP) is a communication protocol that communicates information between the network routers and the multicast end stations. It allows the receivers to request a multicast data stream from a specific group address. However, multicast traffic is sent to a single MAC address but is processed by multiple hosts.The IGMP allows an end station to connect to a multicast group and leave it, while being connected to the group address. It can be effectively used for gaming and showing online videos. Although it does not actually act as a transport protocol, it operates above the network layer. It is analogous to ICMP for unicast connections. It is susceptible to some attacks, so firewalls commonly allow the user to disable it if not needed.
NEW QUESTION # 91
Rosa is working as a network defender at Linda Systems. Recently, the company migrated from Windows to MacOS. Rosa wants to view the security related logs of her system, where con she find these logs?
- A. /Library/Logs/Sync
- B. /Library/Logs
- C. /var/log/cups/access-log
- D. /private/var/log
Answer: D
Explanation:
In MacOS, security-related logs are typically stored in the /private/var/log directory. This location is used to store various system logs, including authentication attempts and other security events. The secure.log file within this directory is particularly relevant for tracking security incidents, as it records authentication attempts and other security-related events. It's important for network defenders like Rosa to be familiar with these log locations to monitor and respond to potential security issues on the systems they manage12.
References: The information provided here is consistent with standard MacOS logging practices and the EC-Council's Certified Network Defender (CND) curriculum, which includes understanding the security mechanisms of different operating systems and how to locate and interpret system logs12. For more detailed information, please refer to the official CND study materials and documents provided by the EC-Council.
NEW QUESTION # 92
Which of the following attack signature analysis techniques are implemented to examine the header information and conclude that a packet has been altered?
- A. Atomic signature-based analysis
- B. Context-based signature analysis
- C. Composite signature-based analysis
- D. Content-based signature analysis
Answer: C
Explanation:
Composite signature-based analysis is a technique used in intrusion detection systems to examine multiple attributes or behaviors over time to identify potential threats. This method can analyze packet headers to detect anomalies that may indicate a packet has been altered. It looks at a series of packets or fragments to determine if they are part of a legitimate session or if they have been manipulated as part of an attack, such as overlapping fragments which cannot be reassembled properly. This approach is more comprehensive than atomic signature-based analysis, which examines single events or packets in isolation, and provides a more contextual understanding compared to context-based or content-based analyses.
NEW QUESTION # 93
Jorge has developed a core program for a mobile application and saved it locally on his system. The next day, when he tried to access the file to work on it further, he found it missing from his system.
Upon investigation, it was discovered that someone got into his system since he had not changed his login credentials, and that they were the ones that were given to him by the admin when he had joined the organization. Which of the following network security vulnerabilities can be attributed to Jorge's situation?
- A. Network device misconfiguration
- B. System account vulnerabilities
- C. Default password and settings
- D. User account vulnerabilities
Answer: C
Explanation:
Jorge's situation is a classic example of the security risks posed by using default passwords and settings. When systems are set up with default credentials, they are often well-known and can be easily exploited by attackers. In this case, since Jorge did not change the login credentials that were given to him by the admin, it allowed unauthorized access to his system. This type of vulnerability is a common oversight that can lead to data breaches and unauthorized system manipulation. It is crucial for users and administrators to change default passwords to something secure and unique to prevent such vulnerabilities.
NEW QUESTION # 94
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.
- A. 169.254.254.254
- B. 255.255.255.0
- C. 18.12.4.1
- D. 172.168.12.4
Answer: C
Explanation:
Class B IP addresses range from 128.0.0.0 to 191.255.255.255. The first two bits of the first octet in a Class B address are always set to '10', and the default subnet mask is 255.255.0.0. Option B, 18.12.4.1, falls within this range, with the first octet being 18, which is between 128 and 191. References: The information is based on the standard IP address classification as per the IPv4 protocol1234.

NEW QUESTION # 96
An administrator wants to monitor and inspect large amounts of traffic and detect unauthorized attempts from inside the organization, with the help of an IDS. They are not able to recognize the exact location to deploy the IDS sensor. Can you help him spot the location where the IDS sensor should be placed?
- A. Location 1
- B. Location 4
- C. Location 3
- D. Location 2
Answer: C
Explanation:
In the context of Certified Network Defender (CND), an IDS sensor should be placed at a location where it can effectively monitor and inspect traffic to detect unauthorized attempts. Location 3, which is situated after the firewall but before the network backbone, is ideal for this purpose. At this location, the IDS can analyze traffic that has passed through the firewall, allowing it to focus on potentially harmful traffic that could affect the internal network. It provides visibility into both incoming and outgoing traffic, enabling comprehensive monitoring and detection of any unauthorized or malicious activity.
References: The placement of IDS is crucial for effective monitoring and detection, as discussed in EC-Council's Certified Network Defender courseware12. It is also aligned with the NIST Cybersecurity Framework, which emphasizes the importance of identifying, protecting, detecting, responding, and recovering from security incidents2.
